That's a rather impressive amount of social transformation, and yet I suspect it's not well studied. Canada is the "dog" of sociology -- a remarkable species that has been falsely assumed to be "ordinary".
Now another experiment is playing out. Canada is a wealthy nation with, compared (only) to the US, a relatively even standard of living with limited pockets of severe poverty and a relatively intact social safety net. That may be why it has a birth rate similar to Italy, Japan, or Denmark -- very low (of course then one might ask why evolution allows relative wealth and prosperity to end reproduction!). Unlike Japan, which seems destined to slowly fade away (Korea's birth rate is too low to provide immigrants and every other nation is too "foreign"), Canada has returned to its historic roots as a nation of immigration.
There's one key difference, however, between Canadian immigration and the US model. Canada has been aggressively managing its immigration stream, with an almost "eugenic" policy of selecting the most economically productive immigrants. This is why I believe Canada will not have a social security crisis. More below ...
