While I have no doubt that there is an attitude towards immigration in a more positive way the recent push for immigration in Canada seems largely work force related.
From an article back in August:
“Immigration is increasingly becoming the primary, if not the only, source of labor force growth” in Canada as the baby boomers retire, said Andrew Agopsowicz, a senior economist at the Royal Bank of Canada.
To make up the shortfall in 2020, the Canadian government in October announced even loftier immigration targets. It hopes to welcome 401,000 permanent residents in 2021, up from a previous goal of 351,000. That target would increase by 10,000 in 2022 and again in 2023."
I guess in other words there's not necessarily an altruistic embracing at least from the Canadian government, citizens' viewpoints may differ. That is still largely contrasted by the U.S.'s viewpoint on workforce and immigration though we recognize certain sectors (like tech, like agriculture, like construction) can be heavily reliant upon immigrant workers.
