I'm a single mother engaged to a Canadian Citizen. I wouldn't mind migrating to Canada w/ my child. Does anybody here know the rules in connection w/ this?

Canadian Immigration is easier than US immigration; however, there are still a whole bunch of rules that need to be followed. I suggest searching for a Canadian Immigration website. Sorry - I don't know any off hand...

Try www.britishexpats.com there is a Canadian board there and some Canadian info on the front page.
