What ocean is on the eastern border of Canada?
Answer
Atlantic
Answer
Atlantic
The Atlantic Ocean lies along Canada’s eastern border. Canada’s Atlantic coastline faces the Atlantic Ocean, including the shores of Newfoundland and Labrador, Nova Scotia, New Brunswick, Prince Edward Island, and the eastern coast of Quebec.
The Atlantic is the world’s second-largest ocean, after the Pacific. It separates North and South America from Europe and Africa, and it connects northward with the Arctic Ocean. Canada’s Atlantic waters have long supported fishing, shipping, naval activity, and trade with Europe.
Canada is also associated with the Gulf of St. Lawrence, the Bay of Fundy, and the Labrador Sea. These are distinct bodies of water connected to or bordering the Atlantic, but they do not change the broad geographic answer to this question: the ocean on Canada’s eastern side is the Atlantic.
A useful neighboring fact is that Canada has three ocean coastlines: the Atlantic to the east, the Pacific to the west, and the Arctic Ocean to the north. The country’s coastline is the longest of any nation in the world.
