Working Remotely from Canada

I'm a Chinese citizen and Canada greencard holder, currently holding L-1A working in U.S. My L-1A visa will expire June 2008 so I plan to move to Canada after that. My question is that if it's possible for me to work remotely for U.S. company while I'm living in Canada.

Any advice is highly appreciated.

That will depend upon the policies of the U.S company, and Canadian immigration law.

I doubt that it would be a problem. Work restrictions typically relate only to domestic jobs - that is to say, countries are usually concerned that somebody without work authorization may take a job that would otherwise go to one of their own citizens or permanent residents, but they don't typically care if you work for an entity that operates outside of their borders.
