Agreed. The biggest problem is funding. I'm working for a startup right now that's (to overuse a phrase) killing it, but I cannot imagine us getting here without a large amount of capital to get off the ground.

We'd have been stuck in garages without the money to really hit the growth curve hard.

I'm a Canadian expat in the US, I cannot imagine starting any sort of capital-intensive venture in Canada just because the investment money does not exist.

If you're building something that doesn't require a lot of funding, by all means do it wherever makes you most happy. If you do need a substantial amount of money though, your options are limited.
