School-wise, the best talent in the country tends to come from UToronto, Waterloo, UBC or McGill. That said, there are tons of great programs all across the country.
We have some accelerator-like programs and initiatives aimed at fostering an entrepreneurial spirit generally[1][2][3]. Nothing comparable to YC as far as guidance and connections go, though. But I don't think anything has been particularly successful.
