Canadians in Shanghai?

Are there many Canadians in Shanghai?

I will be visiting different cities for work this year, so I am hoping to learn about the communities and what it is like to live there as a Canadian because I would love to live in a different city in the future.

How do people usually in meet in Shanghai?
Are there Canadian groups, restaurants or stores?
Where do people go to find information about current & up-coming event/seminar?
Where do Canadians hangout?

Thanks for your comment, eh ;)
Cheers,
