In Toronto you can get some amazing developers for half the price of the U.S. A lot of the really good workers despise the U.S. so much, especially right now because of Trump, that you can steal all the rock stars for your startup by offering smart perks.
Also right now we can bring in foreign workers to staff up operations really easily so this is probably a good idea.
Your customer service probably will have to be out of the U.S. or somewhere outside of Toronto, maybe Saskatchewan.
