1. Europe is a big region, Switzerland, Norway, Iceland, Sweden has far far far more higher living standards than Canada, their total disposable income is higher, even if canadians might get paid decent, cost of housing is crazy, taxes are crazy, you cant get any medical surgery done without years in waitlist, So europe is 10x better than canada (just being frank, Canada was an amazing country 10 years ago, not anymore)
2. Canada also has a huge surge in re-migration, that is, the most skilled immigrants in your country, are leaving for other countries, they only come to take your citizenship, as a safety net, and then try leaving for more better countries (the high income ones, not the rest, they stay back in canada), the number of applications in permanent residency is going down among skilled immigrants, you're receiving a lot more of fraudulent immigration from degree mills who are abusing your immigration rules.
3. Canada is already probably will have the lowest growth and highest decline in income among all OECD countries, and is predicted to stay the same in next 3 decades, if it continues doing the same things.
USA still has a strong immigration procedure, but a lot more countries are now getting skilled immigrants from China, India, other Asian, African and Latin American countries, Japan is slowly going to increase immigration (already starting), a lot of European countries welcome skilled migration like Germany, India itself is surging and giving more high income job prospects (they are struggling at creating blue-collar jobs, but white collar well paid jobs are increasing, with more and more GDCs opening there (Global Development Centres), most major computer chips used are designed either in India or Taiwan, the majority of it, happening in other sectors too now)
Canada is immigration friendly, but as a whole along with its other policies, it's inviting the wrong group of immigrants (low-skilled workers across the world, who'll fight with natives for lower paid jobs and drive down wages) that is not a good immigration policy, America also has better diversity capping immigration for each country at 7% max, Canada's immigration policies are poorly designed, and will continue to hurt the country going forward.
