A quick google search came up with this from an organization that (from the name and content on their site) appears to be an oil industry lobby group:

> Our Northern neighbor has some experience with a carbon tax as well as other mechanisms for reducing carbon dioxide emissions. In 2019, Canada implemented a carbon tax under the Greenhouse Gas Pollution Pricing Act supported by Prime Minister Justin Trudeau. The carbon tax started at $20 per metric ton in 2019, and is scheduled to increase at $10 per metric ton per year until reaching $50 per metric ton in 2022. The carbon tax will stay at that level unless the legislation is revisited and revised. > > A $20 per metric ton carbon tax equates to a 16.6 cent per gallon surcharge on gasoline. In 2022, the $50 per ton carbon tax would increase Canadian gasoline prices by about 42 cents per gallon or about 8 percent.

Even the $50 per ton tax doesn't seem like it actually raises prices all that much. I mean, if you're poor and need to buy gas to get to work it's a detrimental change, but gas prices fluctuate more than that just from oil production changes and geopolitics, and it hasn't stopped price-sensitive purchasers from buying gas-burning cars.
