I'm not yet in Canada, but based on the people i've been following (and talking to), it looks like your opportunities in Canada will be directly connected to 3 factors: (mainly) your english proficiency, your professional field and the city your choose to land/live.
If you arrive in Canada with a solid CLB9+, in a field that requires professionals (like design, architecture, engineering, accounting, aviation, railways... and of course, IT) and opt to live outside of Toronto/Vancouver, the chances of your getting a job that will pay you 50k/yr after 1yr seems pretty reasonable. It's really hard for an engineer to be hired in Canada as a P.Eng again, but as an Analyst (or similar position), it seems feasible.
For a couple, if both succeed on that plan, it means a 100k/yr income. At least that's what I see based on the people from my country that I follow and currently live in Canada. The vast majority of them appear to be doing just fine. But we're talking about people who already arrived as PRs, with solid english skills.
Probably for international students, with CLB7, under a student vise, things are probably harder.
I would love to hear the opinions of people who are already in Canada, as PRs, regarding my view on that matter. As I mentioned, it's all based on the people that I've been following. Are my assumptions realistic?
Of course, all these assumptions are pre - COVID-19. No one knows what will happen with unemployment rates once this is over.
