It is the largest wetland in Canada. It is also one of the largest in the world. This area sits between the Canadian Shield and the shores of Hudson Bay and James Bay. Most of the land is in the province of Ontario. Some parts also reach into Manitoba and Quebec. The region covers about 228,400 square kilometers. This is about 25 percent of all the land in Ontario.

This land is very wet and filled with water. Most of it is made of peat bogs and fens. These are types of peatlands. You can also find salt marshes along the coast. Near the big rivers, there are marshes and wet meadows. Many wide and slow rivers flow through this area. These rivers flow toward the saltwater of the bay. Some of these rivers are the Churchill, Nelson, and Hayes. In Ontario, the Severn, Fawn, and Winisk rivers flow here too.

Long ago, a giant sheet of ice covered this entire area. This happened during the last glaciation. As the ice melted and went away, the land flooded. Now, the plains are slowly rising out of the ocean. This happens because of a thing called post-glacial rebound. Over the last ten thousand years, peatlands have built up here. The plants are a mix of forest and arctic types. You will see moss, lichen, and sedges growing in the soil.

Many animals use these wetlands to live. Migratory birds fly here every year. Snow geese fly north to breed in the coastal marshes.

You might also see shorebirds like the yellow rail. Large animals live in the area too. Polar bears and wolverines can be found here. People also visit to watch beluga whales and seals. Some people go there for fly-fishing in the rivers.

People have lived near this area for a long time. The local Ojibwa and Cree people likely saw this region. However, they did not live there because the land was hard to use. The ground does not drain water well. Later, the Hudson's Bay Company set up trading posts. Some places like Rankin Inlet are still populated today. Small First Nations settlements exist at Moose Factory and Attawapiskat. The land also holds minerals like nickel and chromite. A project called the Ring of Fire may build roads to reach these minerals.
