Is this true for well educated immigrants too? It seems like this might be affecting a limited population, if the educated immigrant goes to Canada, they are aware of what immigration means and might be open integrating instead of living in an immigrants community
Well, if we look at the Statscan economic region that consistently posts the lowest unemployment rate (and where the news regularly reports on the exceptionally high number of job vacancies), only 2,140 immigrants arrived there from 2016-2021 (latest census data). Whereas 1,328,240 immigrants arrived in Canada over the same period.
Is it possible that only 0.16% of immigrants are educated? Well, maybe, but if that's the case it is insignificant enough that it is basically meaningless. Said economic region is home to 0.8% of the population, so immigrants are disproportionately not going there despite the data showing the greater economic need.
Education does not remove the human experience. I expect it is plain hard to be one of almost no immigrants to show up somewhere, even if you come with awareness. You aren't likely to find a familiar culture, or other people going through the same experience, so it can easily become isolating. Immigrant communities beget immigrants because they offer something to immigrants. Life isn't just about work it turns out.
