The Ontario provincial electoral districts each elect one representative to the Legislative Assembly of Ontario. They are MPPs, Members of Provincial Parliament. These districts are coterminous with the federal electoral districts, and are based on the 2013 Representation Order as defined by Elections Canada. The exception is Northern Ontario, whose districts are not equivalent to their federal complements, since the provincial government did not want to decrease the number of districts in Northern Ontario.
