Canadians tend to have a very difficult time with the rude behavior. Generally speaking Canadians are very polite even if they are informally so. There was a running joke by Americans on 'how to spot a Canadian' in a coffee shop or restaurant. They spill a drink and the 1st thing they will do is say 'sorry' out loud and begin cleaning the table. Then they will clean up their own clothes. They can be polite to a ridiculous level (again, informally) creating empty 'bubbles' around cashier counters and 3,4 and more people all insist the other one was first and should therefore go ahead, all insisting on moving back further and waving the other ones in ahead of them.

So no, they do not do well when an elevator door opens and Chinese don't care if you are exiting - they simply and immediately walk directly into the elevator (or subway car or door) making exiting people move around them. Canadians will literally punch people in the face for that. Snorting up huge gobs of phlegm or shooting snot out one nostril is absolutely horrifying to Canadians. They will go apoplectic if someone 'cuts in line' and I mean if a Canadian see's that and is not even waiting in that line. They just see it in another line-up (queue) they will shake with righteous indignation.

No, Canadians, maybe more than most others, they do not handle Chinese manners very well at all. In particular anything they deem as taking unfair advantage at the expense of others.
