Normal supply and demand effect. In Quebec, the first two weeks of July are usually the summer construction holidays. Gas prices will definitely spike during that time period. The best thing you can do is not drive for a while if you can. Staycations will be very popular this year.
I occasionally drive my little Fiat 500 Abarth. I don't need it for daily chores. I usually fill it up when I have half a tank left once a month or more. It now costs $50 Canadian. I barely notice it.
