But Canadians are not so keen on another group: rich, mainly Chinese immigrants who have been moving into the Vancouver area for years and driving up real estate prices to a more than merely remarkable extent. That real estate boom (and a somewhat different boom in places like Toronto) has a major effect on the national economy as a whole. And it makes it easy to blame foreigners for this unbalanced, potentially perilous situation.
Of course, the word racism comes up, in part because British Columbia has a history of excluding Asian immigrants.
But it's not a simple situation. A recent article in the Globe and Mail discussed at length the fact that different groups of Chinese immigrants don't get along with each other; older immigrants and their children and grandchildren don't feel any great solidarity with new immigrants from other regions.
Here is one Globe and Mail article. There are plenty more. Like this one about the not exactly rich, not necessarily immigrant.
