That's sort of right. Quebec's laws apply whether Google has an office there. However, because the contes is conducted virtually, Quebec wouldn't be able to do a thing to a contest holder with no nexus in Quebec. If Google was required to send a representative to Quebec to conduct their contest and didn't abide by the law, that representative might be deported, or in some stricter countries arrested. Google Code requires no such person, of course.
