Immigrant women care workers keep Ontario’s home care afloat under exploitative conditions

Source: The Conversation – Canada – By Naomi Lightman, Associate Professor of Sociology, Toronto Metropolitan University

Despite recent provincial investments, Ontario’s home-care system is still in crisis. Underfunding, rationed care and ideological preferences for privatization of services undermine dignified aging and care for those in need of support at home.

At the same time, home-care providers, who are disproportionately racialized immigrant women, experience precarious, exploitative and sometimes dangerous working conditions.

My newly released research report, entitled “Caring about Care Workers: Centring Immigrant Women Personal Support Workers in Toronto’s Home Care Sector,” is a collaboration with Social Planning Toronto(SPT), a non-profit, community-based agency. In it, we highlight the concerns and preferences of these undervalued workers.

Our report presents data from interviews with 25 immigrant women working as personal support workers (PSWs) in home care in the City of Toronto. Our conversations, conducted between 2023 and 2025, focused on employment conditions and workplace safety, the critical need for systems change and the possibilities for building PSW collective power.

A vital service held together by precarious labour

Home care provides crucial supports to seniors who want to live in their own homes longer, facilitates the autonomy of people with disabilities and aids in the recovery of individuals following a hospital stay.

Their work both supports widespread client preferences to “age in place” and reduces pressure on hospitals and emergency departments. Yet it is routinely neglected and chronically under-resourced.

PSWs provide the majority of home care services. In 2022, an estimated 28,854 individuals were employed as PSWs in the home-care sector in Ontario. Home-care PSWs collectively provided 36.7 million hours of care to Ontario residents in 2023-24 through the provincially funded system.

Immigrant and racialized women comprise the majority of home care PSWs in the Greater Toronto Area. Home-care PSW labour is characterized by low wages, lack of employment benefits, health and safety risks and unique challenges associated with working alone in private homes.

Among PSWs in Ontario, those working in the home and community care sector have the lowest average wage, making about 21 per cent less on average than PSWs working in hospitals and 17 per cent less than those in long-term care. Inadequate provincial funding and inequitable and restrictive funding arrangements are the primary drivers that create and exacerbate these unacceptable conditions.

PSWs are absorbing the real cost of care

Our research participants explained how the normal costs associated with providing home care are offloaded onto them in several ways.

First, most PSWs in home care provide personal care to multiple clients each day. Travel between client homes is a requirement of their work. Yet participants shared that they either receive low pay or no pay for travel time between client homes.

One of our participants, Kemi, explained how travel time works in her agency:

“The travel time that we are paid is one hour. If I’m working five hours, that’s six hours I’ll be paid. But the thing is that the travel time amount is not the same as your regular wage… travel time is paid some amount less.”

If it takes more than an hour a day to travel between client homes, Kemi does not receive any compensation for that additional time. Yet this is a reality for her on a regular basis.

Joy, another participant, noted that PSWs in her agency personally pay more than half of their transit costs:

“They give us $1.60 per travel, but the payment we give the TTC is $3.50. I requested the company to make it the same, or at least a free TTC pass for the month. But the employer said it wasn’t appropriate.”

At the same time, many PSWs have long gaps of unpaid time between client visits during their workday. These gaps in their workday result in a full-time shift but only part-time compensation, with many getting paid for only a few hours each day. The result is full time work for a part-time wage.

In addition, participants noted that PSWs can have their work hours and income reduced if their caseload is reduced. This occurs when a client dies, moves, enters hospital or long-term care, switches home care providers or no longer requires services.

Ann-Marie described the precariousness of working in home care:

“You know why the hours are not guaranteed? For instance, I have eight clients, and out of eight clients, I have three clients that passed away. That’s all my hours reduced until they able to find another client to fit into my schedule.”

Reform must start with fair working conditions

Our report provides detailed policy recommendations targeted to both levels of government, home-care service provider organizations, unions and the community sector.

In particular, we advocate for the creation of a comprehensive public non-profit home-care system where home care workers, Ontario residents receiving care and their families play a central role. Rather than continuing with a fee-for-service model, we recommend adopting a grant-based funding model to better support the full cost of care provision.

We also advocate for developing employment standards for home care PSWs and improvement of public transparency and accountability in home care through data collection and analysis, along with regular public reporting and independent research. And, finally, rather than continuing to allow large home-care companies to extract millions in profit, we want every public dollar to support high-quality care and good working conditions for home care workers.

For the good of everyone in Ontario, it’s essential that the provincial government take bold action to reform the home-care system. The very least we can do for these essential and valuable workers is to ensure fair compensation, guaranteed work hours and good working conditions.

Aging bridges are crumbling. Here’s how new technologies can help detect danger earlier

Source: The Conversation – Canada – By Amirreza Torabizadeh, PhD candidate, Civil Engineering, Concordia University

New signs of deterioration recently discovered on the Île-aux-Tourtes Bridge in Montréal have spurred the Québec government to reinforce beams and install shoring just to keep the structure open.

The bridge carries about 87,000 vehicles a day, yet requires constant monitoring and emergency repairs to ensure its safety.

This is a reminder of how aging concrete can deteriorate and cause safety problems.

Canada has thousands of concrete bridges like Île-aux-Tourtes that are reaching or exceeding their intended lifespans. As these structures age, they become more prone to deterioration, much of it happening slowly and out of sight.

Detecting danger earlier

Our research focuses on the modelling of concrete structures that might deteriorate due to environmental stresses and aging. Our goal is to determine how long a structure remains safe and, if necessary, what retrofitting strategies are applicable.

To fully understand these risks, researchers can make use of the most recent technological advances such as drone imaging, AI-assisted defect detection and non-destructive testing to collect regular and reliable data about a structure’s condition.

Combining these technologies with advanced computer modelling techniques could move Canada towards a system that detects danger earlier, prevents costly failures and supports smarter decisions about repair and retrofit strategies.

Across Canada, many of the concrete bridges built between the 1960s and 1980s are now nearing the end of their service life. The 2019 Canadian Infrastructure Report Card found that nearly 40 per cent of the country’s roads and bridges were in fair, poor or very poor condition, showing how widespread the problem has become.

Due to environmental conditions in Canada, freeze-thaw cycles, road salt and moisture serve to accelerate cracking and surface deterioration. Research on concrete durability in cold climates has documented how these mechanisms gradually reduce structural performance.

Climate change is also intensifying heavy rainfall, temperature swings and loading conditions, all of which place additional stress on aging structures. In Western Canada, seismic vulnerability adds another layer of risk for older concrete bridges.

Together, these factors contribute to growing maintenance backlogs and a pattern where deterioration is often addressed only after it becomes visible or disruptive.

Old inspection models are inefficient

Traditional bridge inspections performed by rope access teams — trained professionals who use ropes and specialized gear to work at height on complex structures like bridges — often require lane closures, disrupt traffic and are expensive.

As a result, these inspections are infrequent, allowing damage to develop unnoticed between inspection cycles. The information collected during these inspections is often inconsistent, since different crews may use different ways of recording defects.

When problems are found late, repairs require more lane closures, detours and long work periods. These shutdowns also carry economic costs because downtime affects businesses, commuters and essential services. Earlier detection would let cities plan smaller repairs and use strengthening methods that cause less disruption.

Cost, time and accuracy are the three main factors engineers must balance when assessing aging infrastructure. Our research focuses on accurately predicting the structural risks by modelling how concrete deteriorates over time by considering the occurrence of cracks and environmental stresses.

But even the best model relies on the sufficiency of the collected field information and how much it represents the current state of the structure. To predict the behaviour of a bridge accurately, data must be precise, consistent and updated regularly, something that traditional inspections rarely provide.

How tech can help

New technological advancements on data science and observation techniques are now changing this landscape.

Drones can capture high-resolution images of cracks and surface damage in minutes, without lane closures or heavy equipment. AI systems can scan these images and highlight subtle patterns that might go unnoticed in a manual survey. Other non-destructive testing methods, like radar or ultrasonic scanning, can detect hidden problems beneath the surface.

When these technologies are combined with advanced computer modelling, civil engineers get a much clearer picture of the state of a structure. This early and accurate understanding helps them plan repairs that are faster and less disruptive. It also reduces downtime — the closures and delays that can create economic costs for businesses and commuters.

With better information, communities can choose repair and retrofit solutions that are more efficient and better timed.

Canada cannot rely on infrequent inspections and emergency repairs to manage its aging bridges. By combining better models with more consistent and automated data collection, engineers can detect problems earlier and avoid the large disruptions that come with last-minute closures.

These tools will not replace engineers, but they will give decision-makers clearer information and more time to plan. Investing in these modern approaches now can help keep our bridges safer, our cities moving and our communities better protected in the years ahead.

Concrete with a human touch: Can we make infrastructure that repairs itself?

Source: The Conversation – Canada – By Mouna Reda, Post doctorate fellow, Department of Civil Engineering, McMaster University

As winter approaches, Canada’s roads, bridges, sidewalks and buildings are facing a familiar problem: cracks caused by large temperature swings. These cracks weaken infrastructure and cost millions to repair every year.

But what if concrete could heal itself like human skin, keeping our structures, roads and bridges strong and saving millions of dollars?

Concrete is the most widely used construction material, known for its durability and low maintenance. Yet it’s still susceptible to cracking.

Concrete is made by mixing cement, water, aggregate and other chemicals used to enhance its properties. As cement reacts with water, it forms a paste that binds everything together.

During this process, changes in volume, improper placement and finishing, and later environmental factors can create cracks. These cracks allow water, other liquids, gases and harmful chemicals to penetrate the concrete, compromising its strength over time.

This challenge has led researchers to eagerly explore what can be done to heal these cracks. In our research, we are researching how self-healing concrete can make infrastructure more durable.

Self-healing concrete

When our skin is cut, it’s able to heal on its own. Inspired by this, researchers started re-imagining concrete with similar abilities.

Traditional concrete is able to mend small cracks when water triggers leftover cement in a process known as autogenous healing. This process, however, is very slow and limited to narrow cracks. Since concrete is man-made, it has limited ability to “self-heal” without a little extra help. This led researchers to develop what is called autonomous healing.

Autonomous healing mimics nature by adding special materials like minerals, polymers, micro-organisms or other healing agents into concrete. These materials react chemically or physically with concrete to fill the cracks.

The first modern concept of self-healing concrete was introduced by American researcher Carolyn M. Dry in the early 1990s. In 2006, Dutch microbiologist Hendrik M. Jonkers developed a special concrete that uses bacteria to heal cracks.

Later, Jonkers and civil engineer Erik Schlangen gained attention with “bio-concrete” that incorporates bacteria in spore form. When moisture enters a crack, the spores activate and produce calcium carbonate, one of the most suitable fillers for concrete.

This process, called microbiologically induced calcite precipitation, can heal cracks up to one millimetre wide. The process, however, is very slow and depends on the presence of calcium and moisture in concrete, which makes applying it on a large scale challenging.

Beyond bacteria

The limitations of bacteria-based self-healing led researchers to explore chemical-based mechanisms. These healing agents will react with water, air, cement or curing agent to fill in cracks quickly.

Healing agents can work in two ways: some use a single material, like sodium silicate. Others, like dicyclopentadiene, need two materials. For a two-component type, a substance must be added to start the reaction, and both materials must be released at the same time to repair cracks.

This chemical method can repair larger cracks and works faster than the bacteria-based approaches but comes with its own challenges. The biggest question is: How can we ensure the healing agent survives concrete mixing and is only released when a crack forms?

To address this, researchers store the healing agent in protective mediums — either a special network (called a vascular network) or tiny capsules. These storage mediums protect the healing material until a crack forms. When that happens, the capsules or network rupture to release the healing agent and fill the crack.

Vascular networks require an external reservoir to supply the healing agent, which makes them difficult to cast, vulnerable to damage during casting and susceptible to leaks. Because of this, encapsulation has emerged as a promising approach.

Encapsulation as a potential solution

Encapsulation involves coating the active agent with polymeric shells to create micro-capsules. Despite its promise, this technique still faces hurdles. Researchers use different methods to make and test the capsules, and there is no standardized way to compare results or test efficacy. The bond between the capsule and the surrounding concrete poses additional challenges and needs more investigation.

In our lab at McMaster University, we are researching the optimum geometrical and mechanical properties of capsules that are compatible with the surrounding concrete. The capsules should survive concrete harsh mixing conditions, while still rupture upon cracking.

We’re also developing a standarized test method to evaluate the survival capsule rate during mixing, and another test to evaluate the efficiency of the self-healing concrete system. And we’re investigating the feasibility of incorporating both bacteria- and chemical-based capsules for short- and long-term self-healing.

More research is needed to determine which self-healing method works best —bio-concrete, chemical-based concrete or perhaps a combination of both.

Ultimately, finding ways to integrate these solutions into infrastructure will benefit communities around the world. Cracks in concrete don’t just look bad; they lead to deterioration over time and costly repairs. That is why developing concrete that resists cracking or heals itself is so important.

Possible ancient artifacts are found in a B.C. thrift shop — and archeology scholars are on the case

Source: The Conversation – Canada – By Cara Tremain, Assistant Professor, Archaeology, Simon Fraser University

An unusual email arrived in the inbox of a faculty member at the department of archeology at Simon Fraser University in the spring of 2024.

This email was from a thrift shop, Thrifty Boutique in Chilliwack, B.C. — unlike the many queries archeologists receive every year to authenticate objects that people have in their possession.

The shop wanted to determine whether items donated to the store (and initially put up for sale) were, in fact, ancient artifacts with historical significance. Shop employees relayed that a customer, who did not leave their name, stated the 11 rings and two medallions (though one may be a belt buckle) in the display case with a price tag of $30 were potentially ancient.

Thrifty Boutique wasn’t looking for a valuation of the objects, but rather guidance on their authenticity.

Eclectic collection

As archeology faculty, we analyzed these objects with Babara Hilden, director of Museum of Archaeology and Ethnology at Simon Fraser University, after the store arranged to bring the items to the museum.

Our initial visual analysis of the objects led us to suspect that, based on their shapes, designs and construction, they were ancient artifacts most likely from somewhere within the boundaries of what was once the Roman Empire. They may date to late antiquity (roughly the third to sixth or seventh century) and/or the medieval period.

The initial dating was based largely on the decorative motifs that adorn these objects. The smaller medallion appears to bear a Chi Rho (Christogram), which was popular in the late antiquity period. The larger medallion (or belt buckle) resembles comparable items from the Byzantine Period.

The disparities between the two objects, suggesting different time periods, make it unlikely they’re from the same hoard. We expect they were assembled into an eclectic collection by the unknown person (as of yet) who acquired them prior to their donation to Thrifty Boutique.

With the exciting revelation that the objects may be authentic ancient artifacts, the thrift store offered to donate them to SFU’s archeology museum. The museum had to carefully consider whether it had the capacity and expertise to care for these objects in perpetuity, and ultimately decided to commit to their care and stewardship because of the potential for student learning.

Officially accepting and officially transferring these objects to the museum took more than a year. We grappled with the ethical implications of acquiring a collection without known provenance (history of ownership) and balanced this against the learning opportunities that it might offer our students.

Ethical and legal questions

Learning to investigate the journey of the donated objects is akin to the process of provenance research in museums.

In accepting items without known provenance, museums must consider the ethical implications of doing so. The Canadian Museums Association Ethics Guidelines state that “museums must guard against any direct or indirect participation in the illicit traffic in cultural and natural objects.”

When archeological artifacts have no clear provenance, it is difficult — if not impossible — to determine where they originally came from. It is possible such artifacts were illegally acquired through looting, even though the Canadian Property Import and Export Act exists to restrict the importation and exportation of such objects.

We are keenly aware of the responsibility museums have to not entertain donations of illicitly acquired materials. However, in this situation, there is no clear information — as yet — about where these items came from and whether they are ancient artifacts or modern forgeries. Without knowing this, we cannot notify authorities nor facilitate returning them to their original source.

With a long history of ethical engagement with communities, including repatriation, the Museum of Archaeology and Ethnology is committed to continuing such work. This donation would be no different if we’re able to confirm our suspicions about their authenticity.

Archeological forgeries

Archeological forgeries, while not widely publicized, are perhaps more common than most realize — and they plague museum collections around the world.

Well-known examples of the archeological record being affected by inauthentic artifacts are the 1920s Glozel hoax in France and the fossil forgery known as Piltdown Man.

Other examples of the falsification of ancient remains include the Cardiff Giant and crystal skulls, popularized in one of the Indiana Jones movies.

Various scientific techniques can help determine authenticity, but it can sometimes prove impossible to be 100 per cent certain because of the level of skill involved in creating convincing forgeries.

Copies of ancient artefacts

Other copies of ancient artifacts exist for honest purposes, such as those created for the tourist market or even for artistic purposes. Museums full of replicas still attract visitors, because they are another means of engaging with the past, and we are confident that the donation therefore has a place within the museum whether the objects are authentic or not.

By working closely with the objects, students will learn how to become archeological detectives and engage with the process of museum research from start to finish. The information gathered from this process will help to determine where the objects may have been originally uncovered or manufactured, how old they might be and what their original significance may have been.

Object-based learning using museum collections demonstrates the value of hands-on engagement in an age of increasing concern about the impact of artificial intelligence on education.

New course designed to examine items

The new archeology course we have designed, which will run at SFU in September 2026, will also focus heavily on questions of ethics and provenance, including what the process would look like if the objects — if determined to be authentic — could one day be returned to their country of origin.

The students will also benefit from the wide-ranging expertise of our colleagues in the department of archeology at SFU, including access to various technologies and avenues of archeological science that might help us learn more about the objects.

This will involve techniques such as X-ray fluorescence, which can be used to investigate elemental compositions of materials and using 3D scanners and printers to create resources for further study and outreach.

Mentoring with museum professionals

Local museum professionals have also agreed to help mentor the students in exhibition development and public engagement, a bonus for many of our students who aspire to have careers in museums or cultural heritage.

Overall, the course will afford our students a rare opportunity to work with objects from a regional context not currently represented in the museum while simultaneously piecing together the story of these items far from their probable original home across the Atlantic.

We are excited to be part of their new emerging story at Simon Fraser, and can’t wait to learn more about their mysterious past.

Donald Trump’s Ukraine peace deal would leave the country vulnerable to future Russian attacks

Source: The Conversation – Canada – By James Horncastle, Assistant Professor and Edward and Emily McWhinney Professor in International Relations, Simon Fraser University

United States President Donald Trump’s envoy, Steve Witkoff, and a key adviser to Russian President Vladimir Putin, Kirill Dmitriev, recently agreed to a 28-point peace plan to end the war in Ukraine.

Such an agreement, on the surface, would be cause for good news. The human toll of the conflict, although shrouded in secrecy by both Russia and Ukraine, is high.

Just one problem: the U.S. and Russia did not include Ukraine in the deliberations. Not only is that patronizing, no matter how the Trump administration has sought to spin it, but it means the agreement reflects Russian demands and goals for the war.

As such, not only is the deal a non-starter, but it also puts Ukraine in the unenviable position of saying no to a mercurial American president.

The search for peace

Since Russia’s full-scale invasion of Ukraine in February 2022, there have been several initiatives seeking peace.

One of the earliest efforts took place in Turkey soon after the invasion. Despite Russia’s efforts to portray Ukraine’s withdrawal from the talks as being American-led, what ultimately scuttled the peace process were revelations of Russian atrocities in the Kyiv suburb of Bucha.

In the aftermath of this failure, both Russia and Ukraine reverted to pursuing their own goals for the conflict. For Ukraine, this meant the complete restoration of its territory from Russian occupation. Ukraine’s failed summer 2023 counter-offensive, however, dashed hopes for a quick victory.

Since this failure, both Ukraine and Russia have accepted that a war of out-manoeuvring one another for a rapid victory is unlikely. Instead, the war in Ukraine is now a protracted, attrition-based conflict.

In such a scenario, the role of outside support is critical. Ukraine has advocated for American participation in peace negotiations, but the talks leading to the 28-point peace plan signalled the Americans were siding with Russia and acceding to Russian demands.

Ukrainian officials have since met with both European and American officials to chart another path forward.

The peace plan’s many problems

Ukraine’s supporters have rightfully argued that the 28-point peace plan heavily favours Russia. The plan’s bias was so evident that U.S. Secretary of State Marco Rubio reportedly told senators it represented a Russian “wish list,” although he later denied saying that.

There are multiple provisions that make the deal unworkable from a Ukrainian perspective.

The first is that under the plan, Ukraine must cede all of Donetsk and Luhansk in the eastern reaches of the country to Russia. While Russia has seized Luhansk in its entirety, key portions of Donetsk remain under Ukrainian control.

Ukraine’s control of these parts of Donetsk goes beyond symbolic value. These areas consist of terrain and fortifications that are ideal for defensive operations. If Ukraine surrendered this territory to Russia, central Ukraine would be left vulnerable to rapid Russian assaults in the future.

Accepting a bad deal?

Ukrainian officials have struck a delicate balance since Trump announced his peace plan. If Ukrainian officials outright reject it, Trump will probably abandon Ukraine at a moment of need. If Ukraine fully acquiesces, it will be left vulnerable to future aggression. It’s also doubtful any officials who sign the Russia-friendly agreement will survive politically.

Ukrainian officials have consequently cultivated their ties with European officials while playing for time on the more contentious issues in the plan. Specifically, President Volodymyr Zelenskyy has said that the territorial aspects of the proposed agreement are the most troublesome.

Realistically, Ukraine isn’t likely to recover areas like Crimea. But Trump asking Ukrainian officials to surrender territory they have not yet lost in Donetsk is a bridge too far.

Unfortunately, Trump appears desperate to reach an agreement, regardless of the cost, judging by the people he has placed in charge of negotiating with Russia — Witkoff and Jared Kushner, the president’s son-in-law.

Witkoff and Kushner are most notably involved when Trump wants results, regardless of the consequence.

Since entering politics in Trump’s first term, Witkoff has been an apologist for Russia and its actions. This stance has not changed in Trump’s second term. In fact, it appears Witkoff coached Russia on how to ingratiate itself to Trump, seemingly placing Russian interests above American.

Kushner’s past diplomacy efforts appear to have enriched him personally, something that does not bode well for the required neutral stance in Russia-Ukraine talks.

A lost moment

Unfortunately for Ukraine, these peace plan complications could not come at a worse time for their war efforts. While Russia pummels Ukrainian cities and is claiming it’s seized the city of Pokrovsk in eastern Ukraine, Ukrainians are simultaneously making sustained attacks on the Russian energy industry.

Direct disruption of Russian energy is perhaps the one area where Ukrainian pressure could affect Putin’s war efforts.

Trump’s attempts to achieve a peace deal at any cost, however, could scuttle any Ukrainian breakthroughs.

Ontario’s Bill 5 erodes good governance in the province

Source: The Conversation – Canada – By Kristen Lowitt, Associate Professor, Environmental Studies, Queen’s University, Ontario

Ontario passed Bill 5, the Protect Ontario by Unleashing Our Economy Act, in June 2025. The omnibus bill amended environmental laws and proposes “special economic zones” where the government can decide what laws will or won’t apply.

The bill eliminates key environmental protections and grants the provincial government sweeping powers to fast-track development with little to no oversight. This risks undermining the rights of Indigenous communities, the public and nature.

As stated by Michel Koostachin, founder of the Indigenous grassroots group the Friends of the Attawapiskat River: “The government is using the ‘tariff war’ as an excuse for greed, to advance personal and private gain.”

Bill 5 is an affront to Indigenous rights and natural law because it authorizes the government to potentially cause irreparable harm to lands and waters without the free, prior and informed consent of affected First Nations and community members.

Despite widespread opposition from First Nations, the public, municipalities, environmental organizations and labour groups across the province, the government continues to advance the policies, amendments and regulations that could further entrench the regressive legal reforms ushered in by Bill 5.

3 concerning proposals

A series of proposed regulations, amendments and policies were posted on the Environmental Registry of Ontario for public comment for 45 days, with the comment periods closing in mid-November. The government now has to consider these comments before deciding whether to approve the proposals.

We highlight three proposals of particular concern:

Special Economic Zones criteria

This proposed regulation sets out criteria to designate special economic zones. No objective or measurable criteria are provided. Rather, the regulation grants the government discretionary power to decide where, and to whom, legal safeguards that are key to protecting Indigenous rights, nature and the public interest will or won’t apply.

Archeological assessment exemption

This proposed regulation will exempt sites that the government deems economically significant from undergoing archeological assessment. Allowing projects to go ahead without considering the archeological value of a site threatens the protection of cultural heritage and jeopardizes Indigenous cultural sovereignty. It allows government to evade their constitutional duty to consult, as it is often these assessments that trigger that duty when a sacred site or artifact is found.

Species Conservation Act

Proposed regulations, amendments and policies under this new legislation would further weaken the protection of species at risk and their habitats. It would remove the public’s right under Ontario’s Environmental Bill of Rights to have a say in decisions that could have serious ecological impacts.

Undermining good governance

Processes like environmental assessments and opportunities for the public to participate in decision-making are in place for a reason. They are essential safeguards for public health, safety and the environment. Allowing governments to disregard them sets a dangerous precedent for decisions to be made without transparency and accountability.

With allied individuals and organizations, Legal Advocates for Nature’s Defence (LAND), a non-profit environmental law organization, has been calling on elected officials to uphold Indigenous rights, treaty promises and environmental justice in the wake of Bill 5. LAND represents and works directly with Indigenous land protectors from Treaty 9 — the very lands where the Ring of Fire mining project is proposed and where the government wants to establish the first special economic zone.

The Ring of Fire is the name given by mining companies to a mineral-rich area in the Hudson-James Bay lowlands. The proposed Ring of Fire project has implications for all of us.

The Hudson-James Bay lowlands in Treaty 9 territory is a region of profound cultural and ecological significance that has been declared protected by Indigenous organizers under their laws.

This region is a refuge for wildlife, an immense carbon sink and the homeland for thousands of Omushkego people who have relied on it since time immemorial. Its protection is needed if Indigenous communities are to continue practising their inherent and treaty rights to live, hunt, fish and protect their lands and waters — and for the government to do their part in combating climate change and biodiversity loss.

Significantly, the impacts of Bill 5 and special economic zones aren’t limited to the North. There is no assurance that the Ontario government won’t set up more special economic zones in the future if it decides it’s “strategically important to Ontario’s economy.”

Overriding human rights and environmental health to advance economic interests is unacceptable. We must continue to urge our elected officials to repeal Bill 5.

AI is perpetuating unrealistic body ideals, objectification and a lack of diversity — especially for athletes

Source: The Conversation – Canada – By Delaney Thibodeau, Post-doctoral researcher, Faculty of Kinesiology & Physical Education, University of Toronto

What does it look like to have an “athletic body?” What does artificial intelligence think it looks like to have one?

A recent study we conducted at the University of Toronto analyzed appearance-related traits of AI-generated images of male and female athletes and non-athletes. We found that we’re being fed exaggerated — and likely impossible — body standards.

Even before AI, athletes have been pressured to look a certain way: thin, muscular and attractive. Coaches, opponents, spectators and the media shape how athletes think about their bodies.

But these pressures and body ideals have little to do with performance; they’re associated with the objectification of the body. And this phenomenon, unfortunately, is related to a negative body image, poor mental health and reduced sport-related performance.

Given the growing use of AI on social media, understanding just how AI depicts athlete and non-athlete bodies has become critical. What it shows, or doesn’t, as “normal” is widely viewed and may soon be normalized.

Lean, young, muscular — and mostly male

As researchers with expertise in body image, sport psychology and social media, we grounded our study in objectification and social media theories. We generated 300 images using different AI platforms to explore how male and female athlete and non-athlete bodies are depicted.

We documented demographics, levels of body fat and muscularity. We assessed clothing fit and type, facial attractiveness like having neat and shiny hair, symmetrical features or clear skin and body exposure in each image. Indicators of visible disabilities, like mobility devices, were also noted. We compared the characteristics of male versus female images as well as the characteristics of athlete and non-athlete images.

The AI-generated male images were frequently young (93.3 per cent), lean (68.4 per cent) and muscular (54.2 per cent). The images of females depicted youth (100 per cent), thinness (87.5 per cent) and revealing clothing (87.5 per cent).

The AI-generated images of athletes were lean (98.4 per cent), muscular (93.4 per cent) and dressed in tight (92.5 per cent) and revealing (100 per cent) exercise gear.

Non-athletes were shown wearing looser clothing and displaying more diversity of body sizes. Even when we asked for an image of just “an athlete,” 90 per cent of the generated images were male. No images showed visible disabilities, larger bodies, wrinkles or baldness.

These results reveal that generative AI perpetuates stereotypes of athletes, depicting them as only fitting into a narrow set of traits — lacking impairment, attractive, thin, muscular, exposed.

The findings of this research illustrate the ways in which three commonly used generative AI platforms — DALL-E, MidJourney and Stable Diffusion — reinforce problematic appearance ideals for all genders, athletes and non-athletes alike.

The real costs of distorted body ideals

Why is this a problem?

More than 4.6 billion people use social media and 71 per cent of social media images are generated by AI. That’s a lot of people repeatedly viewing images that foster self-objectification and the internalization of unrealistic body ideals.

They may then feel compelled to diet and over-exercise because they feel bad about themselves — their body does not look like AI-fabricated images. Alternatively, they may also do less physical activity or drop out of sports altogether.

Negative body image not only affects academic performance for young people but also sport-related performance. While staying active can promote a better body image, negative body image does the exact opposite. It exacerbates dropout and avoidance.

Given that approximately 27 per cent of Canadians over the age of 15 have at least one disability, the fact that none of the generated images included someone with a visible disability is also striking. In addition to not showing disabilities when it generates images, AI has also been reported to erase disabilities on images of real people.

People with body fat, wrinkles or baldness were also largely absent.

Addressing bias in the next generation of AI

These patterns reveal that AI isn’t realistic or creative in its representations. Instead, it pulls from the massive database of media available online, where the same harmful appearance ideals dominate. It’s recycling our prejudices and forms of discrimination and offering them back to us.

AI learns body ideals from the same biased society that has long fuelled body image pressure. This leads to a lack of diversity and a vortex of unreachable standards. AI-generated images present exaggerated, idealized bodies that ultimately limit the diversity of humans and the lowered body image satisfaction that ensues is related greater loneliness.

And so, as original creators of the visual content that trains AI systems, society has a responsibility to ensure these technologies do not perpetuate ableism, racism, fatphobia and ageism. Users of generative AI must be intentional in how image prompts are written, and critical in how they are interpreted.

We need to limit the sort of body standards we internalize through AI. As AI-generated images continue to populate our media landscape, we must be conscious of our exposure to it. Because at the end of the day, if we want AI to reflect reality rather than distort it, we have to insist on seeing, and valuing, every kind of body.

Apparent ancient artifacts are found in a B.C. thrift shop — and archeology faculty are on the case

Source: The Conversation – Canada – By Cara Tremain, Assistant Professor, Archaeology, Simon Fraser University

An unusual email arrived in the inbox of a faculty member at the department of archeology at Simon Fraser University in the spring of 2024.

This email was from a thrift shop, Thrifty Boutique in Chilliwack, B.C. — unlike the many queries archeologists receive every year to authenticate objects that people have in their possession.

Thrifty Boutique wasn’t looking for a valuation of the objects, but rather guidance on their authenticity.

Eclectic collection

Ethical and legal questions

Learning to investigate the journey of the donated objects is akin to the process of provenance research in museums.

Archeological forgeries

Archeological forgeries, while not widely publicized, are perhaps more common than most realize — and they plague museum collections around the world.

Well-known examples of the archeological record being affected by inauthentic artifacts are the 1920s Glozel hoax in France and the fossil forgery known as Piltdown Man.

Other examples of the falsification of ancient remains include the Cardiff Giant and crystal skulls, popularized in one of the Indiana Jones movies.

Copies of ancient artefacts

Object-based learning using museum collections demonstrates the value of hands-on engagement in an age of increasing concern about the impact of artificial intelligence on education.

New course designed to examine items

Mentoring with museum professionals

We are excited to be part of their new emerging story at Simon Fraser, and can’t wait to learn more about their mysterious past.

Fairness for whom? The impact of Alberta’s trans-exclusionary sports law

Source: The Conversation – Canada – By Gio Dolcecore, Assistant Professor, Social Work, Mount Royal University

Alberta’s Fairness and Safety in Sport Act promises protection. We believe that it discriminates and decides who gets to belong in sport.

The act, which received royal assent in December 2024 and came into effect on Sept. 1, 2025, requires organizations like school divisions, post-secondary institutions and provincial sport bodies to create and implement policies for athlete eligibility, including limiting eligibility for female-only divisions to people assigned female at birth.

While framed by the province’s United Conservative Party government as a measure to protect competition and ensure athletes “are able to participate in the sports they love fairly, safely, and meaningfully,” the act bans transgender girls aged 12 years and older from participating in competitive sports for women.

As there is no consistent or conclusive scientific evidence to show that transgender athletes have an inherent advantage, the act appears to be part of an organized anti-trans backlash occurring across the country, and a broader targeting of transgender and gender-nonconforming athletes internationally.

Far from just a local or niche issue, the implementation of this act exposes inconsistencies in sport policy and raises urgent questions about how anti-trans politics are shaping access to sport.

The impact on youth

The Fairness and Safety in Sport Act empowers just about anyone to file a complaint related to an organizations’ eligibility determinations. Incidents like one in British Columbia in 2023 —
a man attending a girls’ track and field meet demanded that a nine-year-old cisgender girl with a pixie cut prove she was not a boy through documentation — demonstrate the impact of this type of gender policing.

The consequences fall on transgender and gender non-conforming youth. For them, being banned from participation brings not only the loss of athletic opportunities, but also heightened experiences of exclusion and stigma.

Teammates and coaches must also navigate fractured team dynamics and a school-based athletic culture that risks becoming less about belonging and more about surveillance. The policy undermines the very developmental and educational values that sport is meant to cultivate.

It also places heavy and often invisible demands on the people who support these children. Parents and caregivers are left to shoulder the emotional work of helping their children process the psychological repercussions of exclusion in ways that surpass the normal responsibilities of parenting.

Research consistently shows that parents of transgender and gender-diverse children face significantly elevated levels of stress compared to parents of non-transgender children. This is largely due to the chronic strain of stigma, discrimination and navigating hostile environments along with the emotional labour of advocating within schools, health care and peer groups.

The impact on society

The act also has implications for varsity athletics and broader sporting cultures at post-secondary institutions.

Universities across the province have been forced to create new internal policies and procedures to align with the act, which place incoming and existing athletes participating in women’s varsity sport under increased scrutiny.

An inconsistency emerges when Alberta athletes step onto fields, rinks and courts outside the province.

Since the national institution for post-secondary sport in Canada (U Sport) still allows transgender athletes to compete according to their gender identity, Alberta now risks excluding its own youth while requiring them to compete under different eligibility standards when facing athletes from other provinces.

In addition, implementing this act will eventually create financial strain for organizations. Administering exclusionary rules requires new systems of eligibility verification, monitoring and appeals — an administrative burden that smaller leagues in particular are ill-equipped to manage.

A 2024 statement by the Alberta 2SLGBTQI+ Chamber of Commerce even urged the government to reject this trans-exclusionary legislation on the basis that it would also reduce Alberta’s market share of tourism and 2SLGBTQI+ travel revenue.

Resistance is necessary

Public response so far to the Fairness and Safety in Sport Act has been mixed.

Since it’s provincial law, school districts and universities have complied, creating internal policies and processes to fulfil the requirements of the act even while its trans-exclusionary nature runs counter to many of their values and commitments to equity, diversity and inclusion.

Some, however, have taken action. One University of Lethbridge faculty member, for example, resigned from the Board of Governors after it was forced to accept the new act.

Egale Canada, a national 2SLGBTQI organization — which, along with Calgary-based non-profit support organization Skipping Stone — has launched legal action against the Alberta government, challenging the constitutionality of the province’s anti-trans laws, and released a statement condemning the Fairness and Safety in Sport Act.

On Nov. 17, the Alberta government tabled legislation that seeks to invoke the notwithstanding clause of the Charter of Rights and Freedoms to insulate its laws from legal challenges. Using the clause would prevent courts from striking down laws for being unconstitutional, and in this context specifically, overrides the Charter rights of gender-diverse people.

This action has spurred widespread condemnation, including from the Canadian Civil Liberties Association and the Alberta Medical Association. Albertans are also making their views heard through MLA recall petitions and public protests.

The human toll of the Fairness and Safety in Sport Act must be recognized and challenged. When people refuse to accept exclusion and the overriding of basic human rights in sport, it can become a space for play, belonging and personal growth.
