MTO (Ministry of Transportation Ontario) is the Ontario provincial government department responsible for highways, bridges, transit policy, driver licensing, and transportation safety. MTO maintains the provincial highway network, sets transportation policy, funds transit projects, and regulates transportation industries. Ontario municipalities work closely with MTO on matters including highway interchange access, provincial road maintenance boundaries, transit funding through programs like gas tax sharing, and road design standards. MTO approval may be required for developments affecting provincial highways or for municipal roads connecting to provincial routes. Other provinces have equivalent transportation ministries under various names.
