Provincial planning includes a provincial plan that guides other land use planning, and a regional development program. Provincial planning takes into account national objectives, coordinating them with provincial and local objectives related to the use of the areas. The provincial plan indicates the desired development of the province.
The provincial plan presents the principles of land use and community structure and indicates the areas necessary for the development of the province. Reserves shall be allocated only to the extent and with the degree of precision required for the purpose of coordinating the use of areas in more than one municipality for national or provincial purposes.
