Not just Canada, but really anywhere else. In any city with strong public universities there are strong pools of skilled tech workers. But tech companies are bizarrely centralized. Microsoft, etc, expects everyone to head over to their neck of the woods, and a lot of people just aren't going to do that.

Build substantially sized outputs in any of: Atlanta (Duke, GT, UNC), Philadelphia (Penn, Penn State), Boston (MIT/Harvard), Chicago (U of C, NU, U of I), Minneapolis (U of Minn.), Austin (U of T), etc, and you'd have access to a large pool of well-educated tech workers. These folks aren't going to leave their families behind and go to the left coast for jobs, but they'd love to work for a big well-known tech company.
