Question

I am in Canada with a single entry visitor Visa. Can I go to USA and come back to Canada before visa expires.?

Answer 1

Yes you can, I know that for a fact. You can re-enter Canada multiple times from the mainland US with a single entry visa. It's part of the Western Hemisphere Travel Initiative. I'm not sure about the other territories of the US though

Answer 2

Single entry means just that.

Use Canada's official web site to see how to get around this; I would not trust what someone offers here as concrete advice; they might just want to mess you up.
