Canada

Canada is already dealing with record numbers of refugee claimants: In July, almost 20,000 people filed refugee claims, according to Immigration and Refugee Board data -- the highest monthly total on record and driven by global displacement, advocates and experts told Reuters.

The number has since dipped, to about 16,400 in September, but remains historically high. There are more than 250,000 claims pending, according to the board.

Canada's government has slashed the number of permanent and temporary immigrants but has less control over how many people claim asylum.
