Regional government is a tier of local government serving areas larger than individual municipalities, providing services that benefit from regional coordination. In Ontario, upper-tier municipalities like Peel Region, York Region, and Durham Region oversee lower-tier cities and towns, delivering services like regional roads, policing, social services, and water systems. BC's regional districts provide regional services while respecting municipal autonomy. Quebec's MRCs serve regional planning functions. Regional governments allow coordination across municipal boundaries while maintaining local identity. Not all areas have regional government—some provinces dissolved regional structures, while single-tier municipalities handle all local services themselves.
