Canadian wages were depressed even before the immigration wave. Every Canadian had a sibling or cousin who was living in America in the 90s and 2000s.
Heck, in 2000 the median household income in Canada was around US$32K [0] compared to US$42K in the US [1] despite CoL being roughly the same or higher.
If you want a boogeyman for why Canada stagnated, ask why your political class (both Conservatives and Liberals) turned energy in what is a de facto petrostate into an ideological war while American governers on both sides of the aisle backed both fossil and green energy projects (eg. Rick Perry and wind, Jerry Brown and oil in Bakersfield).
