It does not match my own experience. I worked a few years in Canada (Québec) and liked it very much. I found that the work-life balance was much better than in France. It was more constant throughout the year. People have fewer vacations than in France 3-4 weeks/year with a few sick days vs 6-8 weeks/year but the daily working hours are lower (9-5) with quick lunch break where in France it is more 9-7 with a long lunch break (only in the private sector and in IT).
The more constant working pace is much better for work. In France it is very complex to schedule a meeting when everybody can attend (there's always someone in vacation) and in summer it is nightmare for managers to find people to make a project going forward. The mood at work was much better in Canada, people were more friendly, less stressed due to a better organization (easier than in France) and also to be fair due to a lower unemployment rate.
I did not have the impression to work more than in France to stay afloat, but maybe because because it was going smoother.
