Guys I'm not too sure about how a criminal record will fuck up your chances of coming to work in Canada, but I do know of a guy from the States was refused entry to Canada because of a DUI he picked up years before. This guy had all of his papers lined up, he was working for the same company as he does in the states, he was just coming up for a month or two to help out, and they turned him away! You'll likely need to get some kind of pardon before you can come.
