The Hudson Bay Lowlands is a vast wetland located between the Canadian Shield and southern shores of Hudson Bay and James Bay. Most of the area lies within the province of Ontario, with smaller portions reaching into Manitoba and Quebec. Many wide and slow-moving rivers flow through this area toward the saltwater of Hudson Bay: these include the Churchill, Nelson and Hayes in Manitoba, Severn, Fawn, Winisk, Asheweig, Ekwan, Attawapiskat, and Albany in Ontario, and the Harricana, Rupert and Eastmain in Quebec. This is the largest wetland in Canada, and one of the largest in the world. The region can be subdivided into three bands running roughly northwest to southeast: the Coastal Hudson Bay Lowland, Hudson Bay Lowland, and James Bay Lowland.
