I feel like if you are at the top of your game, and can make it at any of the major tech companies or can start your own startup without trouble at finding funding, the U.S. is way better. Most of my friends, including myself, earned 1.5-3x what we'd earn even in a major city as Toronto.

And if you happen to join a great tech company, chances are the health insurance you'll get is superior to the general public healthcare system in Canada.
