I believe we do sponsor visas, but I'm checking to be sure...
In any case, we have offices around the world. So even if this specific position can't work, feel free to have them email me about other opportunities.
Sounds like a good opportunity. Are there developer positions in Toronto? (I had a look at the careers' site and there seems to be many senior positions so I'm not sure if I can fit in)
(this isn't necessarily for me, but I do know people who might take you up on your offer if you do)
