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.
