Canadian provincial electoral districts

Canadian provincial electoral districts have boundaries that are non-coterminous with those of the federal electoral districts, except for districts in the province of Ontario, where districts in the Southern Ontario region are coterminous while those in Northern Ontario are not. Otherwise, provincial electoral districts tend instead to be smaller, ranging from just over half the size of each federal district (Quebec) to a seventh (PEI).
