In my experience, those numbers for Canadian salaries would be ridiculously low. Also, I'm assuming those numbers are converted to USD. Even if they look lower, you have to consider what kind of lifestyle the salary buys you where you are earning it. In my experience, the real reason people leave isn't so much salary, as lack of opportunities.
