Add it all depends on what state/provinces you're comparing. I would fathom to guess that the lowest in Canada vs. the highest in the US isn't all that different, especially if you don't take advantage of country specific deductions.
Well, for example, Albertans pay less tax (federal and provincial combined) than Californians, but more than Washingtonians (who pay no tax, but also have to pay for their own healthcare). Keep in mind, raw salaries tend to be higher in Canada, as is cost of living. It'd be pretty complicated to actually sit down and puzzle out real take-home wages as compared to PPP, but I doubt there'd be a massive difference.
