«The Grand River watershed drains an area of 6,500 square kilometres to Lake Erie in southwestern Ontario just to the west of the Greater Toronto area. Land use within the basin is varied, with agricultural and rural land used dominant in the northern and southern portions, and urban land uses concentrated in the central region. The natural beauty, cultural diversity and recreational opportunities of the river system have been officially recognized through the designation of the Grand River as a Canadian Heritage River.»
