Science is under attack and it’s causing real harm to people, communities, and public trust. 

Health misinformation spreads for many reasons: profit, politics, or simply to create confusion and erode trust in science. Regardless of intent, these lies are everywhere, shaping public opinion, influencing health decisions, and even driving policies. The results? People get hurt, and lives are put at risk.

Together, we can make the Canadian information environment more resilient and protect the health of Canadians. We all have a role to play in standing up for science. Together, let’s speak up and say unwaveringly that #ScienceMatters.

Share with us how false health information is impacting you, Canada and the world.
