The cost varies, of course, depending on the number of vehicles the consumer owns. It also depends on the type of home heating used, whether it is gas or some other type. According to the Institut du Québec though, which published a report in November 2025, the cost is about $575 per household in Quebec. That is, of course, for a one-car household.
We also have to consider the impact of this tax on the cost of groceries. Even if you don't have a car, you do pay the cost of the carbon tax, unfortunately. So it's roughly $500 to $600 per household.
We must also remember that, according to projections from Quebec's environment department, the cost of the carbon tax is expected to double by 2030. Unfortunately, that cost will also increase for all Quebecers.
