Climate Misinformation is Becoming a National Security Threat. Canada Isn't Ready for It

When a crisis strikes, rumors and conspiracy theories often spread faster than emergency officials can respond and issue corrections.

In Canada, social media posts have falsely claimed wildfires were intentionally set, that evacuation orders were government overreach or that smoke maps were being manipulated. In several communities, people delayed leaving because they were unsure which information to trust.

This wasn't just online noise. It directly shaped how Canadians responded to real danger. When misinformation delays evacuations, fragments compliance or undermines confidence in official warnings, it reduces the state's ability to protect lives and critical infrastructure.

At that point, misinformation is no longer merely a communications problem, but a national security risk. Emergency response systems depend on public trust to function. When that trust erodes, response capacity weakens and preventable harm increases.

Canada is entering an era where climate misinformation is becoming a public-safety threat. As wildfires, floods and droughts grow more frequent, emergency systems rely on one fragile assumption: that people believe the information they receive. When that assumption fails, the entire chain of crisis communication begins to break down. We are already seeing early signs of that failure.

This dynamic extends far beyond acute disasters. It also affects long-running climate policy and adaptation efforts. When trust in institutions erodes and misinformation becomes easier to absorb than scientific evidence, public support for proactive climate action collapses.
