canada? no, very little chance. he told a joke that scared canadians.  mexico, slightly higher chance. might invade to get rid of the cartels but not fight the government.  greenland is a possible consideration, it wasn't a joke the same way the canada comment was, the land has a lot of valuable resources that aren't being tapped to their full potential that we want. this seems to just be greed based, hopefully we can find a way to buy it, i don't think we'd go to war over it. panama is going to happen, that one is almost for sure.
