The Internet Is Playing Doctor — and It's Getting People Hurt
A new survey from the Canadian Medical Association (CMA) is painting a troubling picture of how misinformation is making its way from social media feeds and search engines into examination rooms across the country.
According to the survey, Canadian physicians are increasingly being forced to intervene when patients arrive at appointments with incorrect self-diagnoses or dangerous treatment ideas sourced from online content. Dr. Iris Gorfinkel, a Toronto-based family doctor and clinical researcher, put the stakes bluntly: when it comes to health information found online, it's "like a coin flip" as to whether what a patient reads is actually correct.
That's a sobering statistic for a country where health literacy and timely access to care are already persistent challenges.
What Doctors Are Seeing in the Exam Room
The problem isn't just the occasional wrong WebMD result. Physicians say patients are arriving with firm convictions about their conditions, often shaped by algorithm-driven content designed to maximize engagement rather than accuracy. In some cases, people are delaying or refusing evidence-based treatment in favour of remedies they found in YouTube videos or wellness influencer posts.
For family doctors — who are already stretched thin amid Canada's primary care shortage — having to spend precious appointment time untangling misinformation adds another layer of strain to an already overburdened system.
Dr. Gorfinkel noted that the issue is compounded by the sheer volume and apparent authority of health content online. Slickly produced videos and confident, jargon-filled posts can feel more persuasive than a brief consultation with an overworked physician.
Why This Is a Systemic Problem
Health misinformation isn't new, but the speed and scale at which it now spreads is unprecedented. Social platforms optimized for engagement tend to amplify emotionally resonant content — and fear-based health claims fit that mould perfectly.
The CMA has been pushing for greater accountability from tech platforms hosting health content, as well as better health literacy education in schools and communities. The association argues that the burden of correction shouldn't fall entirely on individual doctors.
There's also a trust dimension at play. When patients feel dismissed or unheard by the medical system — a common experience, particularly for women and marginalized communities — they're more likely to seek validation elsewhere, even if that means turning to sources with no medical credibility.
What You Can Do
Health Canada and medical associations recommend a few practical steps for evaluating online health information:
- Check the source: Look for content from established medical institutions, government health agencies, or peer-reviewed journals.
- Be skeptical of certainty: Legitimate medical content acknowledges complexity and uncertainty. Red flags include guarantees, miracle cures, or content that tells you to distrust your doctor.
- Use the HONcode standard: The Health on the Net Foundation certifies websites that meet basic standards of credibility.
- Bring questions to your doctor: It's okay to come to an appointment with things you've read online — the key is framing them as questions, not conclusions.
The CMA's findings are a reminder that in the information age, knowing where not to look for health advice may be just as important as knowing where to look.
