A growing number of Canadians are encountering health misinformation, with serious consequences for their health, according to new findings from the Canadian Medical Association (CMA). The 2025 CMA Health & Media Annual Tracking Survey, conducted by Abacus Data, reveals troubling trends in how misinformation is affecting Canadians’ physical and mental well-being.
The survey found that 37% of Canadians are forced to turn to the internet for health information because they lack access to a doctor. Of those, 23% reported experiencing negative health reactions after following online health advice. The study also highlighted that 43% of Canadians are experiencing mental distress or increased anxiety due to exposure to misinformation, demonstrating the far-reaching impact of inaccurate health content.
The CMA has raised concerns about the role of social media in spreading health misinformation, with algorithms designed to prioritize engagement over accuracy. “About 6.5 million Canadians don’t have a primary care provider, and that is pushing people to find solutions to their health problems on their own, online,” said Dr. Joss Reimer, president of the CMA. “We’re calling on all social media platforms to take accountability for the impact misinformation is having on the health of Canadians and take immediate action to stop it.”
The survey revealed that 43% of Canadians are highly vulnerable to believing health misinformation, while an additional 35% are moderately susceptible. Many respondents said access to trusted health information helps them feel empowered to make better decisions and combat the spread of false information.
The CMA has also emphasized the importance of health care reform as a long-term solution to address the gaps in the system that push Canadians toward unreliable sources of health advice. Key proposals include team-based care, reducing the administrative burden on physicians, and implementing pan-Canadian licensure to improve access to care across the country.
To combat the spread of misinformation, the CMA is investing in initiatives such as Healthcare For Real, funding health journalism projects, and supporting physicians who share trustworthy information online. These efforts are part of the CMA’s broader vision to create a sustainable and accessible health care system that prioritizes equity, diversity, and the well-being of all Canadians.
“The CMA is committed to driving change through advocacy, collaboration, and knowledge sharing to ensure all Canadians have access to accurate health information and care,” Dr. Reimer said.
With millions of Canadians navigating health challenges without adequate support, the CMA’s call for immediate action underscores the urgent need to address the dual crises of misinformation and limited health care access.
