Nothing really, although there is business class immigration. Basically you pay half a million dollars and you get a visa. The newest immigration path is the canadian experience class. Its a fairly streamlined process if you post-secondary education and/or a couple years of work experience in Canada. Or you can do what I did and shack up with a Canadian :)

Ah, same as last time I looked then. About my only option is to spend a few years at university before launching a startup. Not really a practical path forward...

"I think there is a lot of space in Canada for this sort of thing."

Agreed, though a lot of the talented devs/designers end up moving to the U.S.
