Ring the bell, because it's time to school your sorry @ss about Multiculturalism.
First off, you're confusing two very different things. Nations with different people from all over are Ethnically Diverse.
Multiculturalism is a Canadian-invented system for integrating immigrants into a united and unified nation.
Thus far, only Canada actually has it. Nobody else implemented everything necessary to make it work properly.
But that's their own damn fault for screwing up like retards. And it's why it doesn't work anywhere but Canada.
Canada first invented Biculturalism to bridge the gap between its French and English founding cultures:

Then Canada invented Multiculturalism to bridge the gaps with the Rest Of Canada:

All of that started more than half a century ago.
And the results of Canada's 50 year head-start on diversification vs. the rest of the world are incontrovertible:
