Canadian here. I have my doubts on that; I had some devs that's consistently pulled 280 hours a month and once hit I think 320 hours. His salary was $59,000 CAD a year, and I believe the junior devs working with him were earning $11/hr circa 2010 ish and were working fairly close to those hours. The longest work day I've had is 40 or 50 hours without sleep to meet a deadline that and then had to be in bright and early the next morning. But there's been more then a few times a year that I ended up sleeping in the office because I missed the last 1:00am train out. Not all Canadian companies are like that anymore then all American companies are like Amazon or Google. Nor do I claim to understand why this is the case, but at least from what I've seen, Canadian tech salaries do lag quite a lot compared to US salaries compared to the skill demanded.
