This is great news for both Canadian and international founders. Is the next step having an additional Canadian office for those that can't get US visas? Canada has a generous startup visa for founders coming from other countries [0]. [0] http://www.cic.gc.ca/english/immigrate/business/start-up/
The Canadian visa might sound appealing at first blush but won't help for ycombinator founders as far as I know. To be eligible you need to have funding from a canadian venture fund, see below. I guess ycombinator could setup a Canadian fund and apply for the funding eligibility, but with the principles being mostly American and living in the US, I'm guessing it would be a very tough sell. http://www.cic.gc.ca/englis…
We don't need YC ruining Canada with hopped up "startup" bros. If we even need more VC firms (I don't think we do), let indie VC or something like it come up.
Edit: This isn't meant to mean people shouldn't start companies here. They should. But they should do it firmly grounded in reality, not based in SV VC world which has very little to do with building solid long term businesses.
