“The value of Canada’s health data is immense,” writes Dr. Kumanan Wilson, CEO, Bruyère Health Research Institute and an internal medicine specialist at The Ottawa Hospital and the University of Ottawa, Ottawa, Ontario, with coauthors. “The sovereignty risks associated with these data are real. If Canada is to lead in the health AI space, it must move quickly to establish long-overdue privacy and technology safeguards.”
The rise of artificial intelligence (AI) and its reliance on massive amounts of data has increased the value of these data and created new risks on top of pre-existing concerns about health data being used by other countries for national security purposes.
“Serious privacy, security, and economic risks arise when companies in other countries hold and use Canadian data. Given the rapidly changing political climate in the United States, preserving the sovereignty of Canada’s health data — notably, ensuring that the data are subject to Canadian laws and legal systems — requires renewed focus,” writes coauthor Dr. Michael Geist, a Canada Research Chair in Internet and e-Commerce Law, and professor at the Centre for Law, Technology and Society, University of Ottawa.
Canada’s health system is largely reliant on US providers that manage electronic medical record systems for hospitals and store encrypted data on servers or cloud servers. Although these servers are located in Canada, they are owned by major US companies Microsoft Azure, Amazon Web Services, and Google Cloud.
Europe has expressed similar concerns for their region. For example, the recent Clarifying Lawful Overseas Use of Data (CLOUD) Act in the US that potentially allows US law enforcement to access data held by US companies in other countries could be a threat.
To protect health data in Canada, the authors suggest a multipronged approach:
Ensure data security by requiring encryption by default
Include requirements in federal and provincial privacy laws to keep data in the originating location
Implement rules in Canadian privacy laws against disclosure of data to foreign jurisdictions
Invest in creating Canadian cloud servers to ensure data resides in Canada with Canadian providers
“Canada should consider mechanisms by which our data could be used safely, securely, and in a privacy-compliant manner by Canadian private-sector entities to support the development of domestic health AI algorithms,” the authors write. “Implementing such measures will ensure that health care decisions are based on data representative of Canada’s population, and will support the growth of domestic companies, supporting a better health system and growing tax base.”

He envisions supporting not only clinicians to innovate, but also health care organizations and the larger health system.
“Ideally, health care systems will evolve into living laboratories that enable clinician- and patient-driven solutions supported by health care organizations as well as business and health care system leaders. This is not a new proposition; in 2015, an advisory panel on health care innovation previously advocated for this very concept in Canada,” writes Dr. Muhammad Mamdani, director of the Temerty Centre for Artificial Intelligence Research and Education in Medicine (T-CAIREM) at the University of Toronto and vice president ...
Virtual care network for rural and First Nations communities

VIEW EMBARGOED ARTICLE
While the virtual delivery of health services expanded rapidly during the COVID-19 pandemic, many regions have decreased use of these services in recent years. In B.C., however, a unique pan-provincial partnership led by the Rural Coordination Centre of British Columbia (RCCbc), the First Nations Health Authority, the B.C. Ministry of Health, and the University of British Columbia (UBC) Digital Emergency Medicine Unit has worked together to build and grow a network of virtual services to support patients, physicians, and health care providers in rural communities.
Initiated in March 2020, the RTVS network is publicly funded and designed to ...
Dementia takes 3.5 years to diagnose after symptoms begin
2025-07-27
People with dementia are diagnosed an average of 3.5 years after symptoms are first noticed, or even longer (4.1 years) for those with early-onset dementia, finds a new study led by UCL researchers.
The study, published in the International Journal of Geriatric Psychiatry, is the first systematic review and meta-analysis of global evidence examining time to diagnosis in dementia.
The researchers reviewed data from 13 previously published studies which took place in Europe, US, Australia and China, reporting data on 30,257 participants.
The research team was investigating the average interval between ...
Robotic space rovers keep getting stuck. UW engineers have figured out why
2025-07-25
MADISON — When a multimillion-dollar extraterrestrial vehicle gets stuck in soft sand or gravel — as did the Mars rover Spirit in 2009 — Earth-based engineers take over like a virtual tow truck, issuing a series of commands that move its wheels or reverse its course in a delicate, time-consuming effort to free it and continue its exploratory mission.
While Spirit remained permanently stuck, in the future, better terrain testing right here on terra firma could help ...
New research shows how immigration status can become a death sentence during public health crisis
2025-07-25
In the United States, immigration status has long created hierarchies within our society, where some can participate fully in public life, while others are excluded. These divisions have serious consequences for our communities, including when it comes to public health. A research project led by the University of California, Santa Cruz recently uncovered a particularly alarming example of this effect by looking back on excess deaths in California throughout the course of the COVID-19 pandemic.

University of Toronto Engineering researchers develop safer alternative non-stick coating
2025-07-25
A new material developed by researchers from University of Toronto Engineering could offer a safer alternative to the non-stick chemicals commonly used in cookware and other applications.
The new substance repels both water and grease about as well as standard non-stick coatings — but it contains much lower amounts of per- and polyfluoroalkyl substances (PFAS), a family of chemicals that have raised environmental and health concerns.
“The research community has been trying to develop safer alternatives to PFAS for a long time,” says Professor Kevin ...
Good vibrations: Scientists use imaging technology to visualize heat
2025-07-25
Most people envision vibration on a large scale, like the buzz of a cell phone notification or the oscillation of an electric toothbrush. But scientists think about vibration on a smaller scale—atomic, even.
In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois at Urbana-Champaign have used advanced imaging technology to directly observe a previously hidden branch of vibrational physics in 2D materials. Their findings, published in Science, confirm the existence of a previously unseen class ...
More ecological diversity means better nutritional resources in Fiji’s agroforests
2025-07-25
Indigenous agroforests (food-producing agroecosystems where trees and crops grow together in forest-like environments) may offer valuable insights for addressing two of the world’s biggest challenges: declining biodiversity and rising non-communicable disease, according to research led by University of Hawaiʻi at Mānoa researchers. Published in July 2025 in Global Food Security, the study found that agroforests with greater ecological diversity also offer a more nutritionally diverse food supply.
The team analyzed 48 Indigenous agroforests in Fiji using a trait-based framework. Focusing on specific plant characteristics important for ecological resilience, such as ...
