Research Co.: Canadians Back More Climate Action

Most Canadians accept its urgency and favour stronger action, though partisan divides remain.

New polling from Research Co. offers an updated look at how Canadians view climate change—and whether they are willing to pay to address it.

The survey finds that 63% of Canadians believe climate change is real and primarily caused by human activity. Another 21% say the climate is changing, but attribute it to natural causes. Only 9% say climate change is merely a theory that has yet to be proven.

These views are broadly consistent across demographic groups, but partisan differences are more pronounced. Among 2025 voters, 81% of Liberal supporters say climate change is primarily human-caused, compared to 68% of New Democrats (small sample, interpret with caution) and 44% of Conservatives.

Conservative voters are also the most likely to attribute climate change to natural causes (34%) or to say it remains unproven (16%).

With nearly two-thirds of Canadians accepting human-driven climate change, it follows that 66% describe it as a major global crisis, while another 20% consider it a minor one. Just 9% say it is not a crisis at all—roughly the same share who reject its scientific basis.
