Hudson Bay Lowlands Hudson Bay Lowlands are 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 salt water 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 (a narrow band along the northern coast), Hudson Bay Lowland (a broader band extending to slightly south of the Ekwan River), and James Bay Lowland (all the rest of the southern/eastern lands, making up close to 50% of the total Lowlands area).
