Why is Saskatchewan one of Canada’s two provinces without a saltwater coast?

Saskatchewan is one of Canada’s two provinces without a saltwater coast because of its inland geographic location within the Prairie Provinces of central North America.1

The province is situated between the 49th and 60th parallels of latitude and is bounded by artificial borders rather than natural features like coastlines. While its rivers drain into the Arctic Ocean, the Atlantic Ocean, and the Gulf of Mexico, the province itself is entirely landlocked.12
