You're listing two companies that are veritable unicorns in Toronto. There are a handful of successful mid-level companies like those in the city, and tens of thousands of hungry developers earning far less at non-technologically focused companies.

The average Torontonian (in any field) earns ~$50-70k and costs here are quite high still, even if they trail San Francisco by ~30%.

To wit: on that average salary you certainly won't starve, but pick one: save money, buy a car, have a child (and that might be a stretch).
