Contained within the Atlas of Canada Poster Map Series, is a map depicting the 5 main watersheds in Canada. Building Canadian Water Connections initiative and the Canadian Wildlife Federation have collaborated to produce this map that promotes the importance of watersheds through education. Canada's five ocean watersheds are colour-coded on the map: Pacific Ocean, Arctic Ocean, Hudson Bay, Atlantic Ocean and Gulf of Mexico. Each of these five massive landscapes contains a hierarchy of watersheds. This map depicts 594 watersheds, most of which are connected and ultimately flow into an ocean.
