You don't get paid like an ultra rockstar that lives in a different strata of society than other people, but it being Montreal where rent is affordable and events like the International Jazz Fest, Tam Tams, or drinking wine in one of the many parks is free, and you move all over the island with high quality public transport, it's for the better.
However, it feels a little bit hollow sometimes and like not a lot of real tech work is being done. Lots of stuff geared towards yuppies and going to coffee shops and renting pads and shopping, not a lot of really groundbreaking stuff.
There's gaming companies (eg: Ubisoft), old ex-startups (eg: Shopify), new startups (eg: Transit), Google and Microsoft have offices here, big investment into machine learning research in local universities, etc. It's a college town... for 5 universities... in the downtown of a great city.
There's probably better places to go if you want a super prestige-track career, but I doubt there's many places that are more fun or better balanced.
