Nope. Teachers salaries would be similar to that across Canada. Software dev salaries would be very close, with some exceptions. Winnipeg/Calgary/Edmonton are all very similar to Saskatoon.

There would be some higher paying opportunities in Van/Tor/Mtl. But an $200K individual contributor software dev is a truly a Unicorn in Canada.

Lots of reasons, but the biggest is that simply don't have the ultra profitable FAANGs that drive up salaries.

Canadian software engineering salaries are bizarre though. I was making more in Africa than the average SDE in Vancouver

Hey look at that, another Winnipeger. Winnipeg, as well as the other small prairie cities I'd imagine, also have the disadvantage of just not that much competition and not that much in terms of newer rentals. When I moved to Vancouver 6 years ago, I doubled my salary from ~42k to ~80k. Most of the well paying jobs from that time were for Java devs at the big 3 or 4 insurance companies. If I wanted to work there, there weren't really many nice apartments nearby. Some were built way out in burbs, and now there's a few downtown and in Osbourne, but it's slow going.
