The comparison between the colonists who left the US for Canada and Palestinians who left their homes in what is now Israel would be a little bit more correct if the settlers who left the US did so because they were fleeing for their lives. Is that why they left to go to Canada? The other problem is that the colonists who left for Canada really are more appropriately compared to Israelis of European origin than Palestinians, since both groups are/were interlopers on indigenous peoples' land.
