Most people would agree that you shouldn't have to pay someone else's tax bill. Despite all of the myths surrounding tax filing, this one is actually in accordance with Canadian law. If a relative of yours were to die owing money, you have no obligation to pay their debts. It doesn't matter who they are, parents, siblings, aunts or uncles. If they have spent all their money, and die having nothing but debts, you're in the clear. However, unlike people whose debts die with them, a government's debt is carried forward forever (or until it's paid off). As we move through time, we're getting closer and closer to the point where it will be impossible to "clear our tab."
