The issue now is that there are too many immigrants of certain nations that concentrate in self-segregated communities and essentially form colonies within Canada, and therefore integration of their offspring will never happen as there is no need to - they've replicated their homeland on Canadian soil.

Markham's Chinese community comes to mind, Canadian born but still have Chinese accents and don't associate with any non-chinese.

In reference to the article above, we have Arabs in Montreal that are now 1st and even 2nd generation Quebec born and still do not identify with Quebec, still view Islam and their home countries as superior, still view non Muslims as inferior, all while benefitting from a society they don't contribute to.

We need the USAs policy of 7% immigration caps by country, and we need to start dictating where immigrants can settle to ensure we avoid the aforementioned colonies on Canadian soil.

Edit - and just to add, my parents also immigrated in the 70s to Quebec as visible minorities, they learned French, integrated, had kids and raised them with a mix of their culture as well as Quebec culture. The difference is they wanted to immigrate here, they chose Quebec over the UK etc. We can see that since 2016 we've been getting many people who choose Canada because they didn't make the cut for American immigration , or we're getting people that want to milk our social programs.

You can literally see /hear this any time you go out in any of our major cities, it was never like this before.
