Study Tip
Canada shares a long coastline with the Atlantic and Pacific Oceans, and one of the world's most northern and remote bodies of water.
What should you know about this topic?
Canada is bordered by three oceans: the Pacific Ocean on the west, the Atlantic Ocean on the east and the Arctic Ocean to the north. This is why Canada's motto, A Mari Usque Ad Mare, means from sea to sea, and why Canadians sometimes describe their country as stretching from sea to sea to sea.
Canada is the second-largest country in the world by land area, and it has the longest coastline of any country. To the south lies the United States, and the border between the two countries is the longest undefended international border in the world. Discover Canada explains that each coast has shaped Canada's history and economy. The Atlantic coast was the centre of early European fishing and settlement. The Pacific coast is home to the Port of Vancouver, Canada's largest and busiest port, which handles much of Canada's trade with Asia. The Arctic coast borders the North, where the Inuit have lived for thousands of years.
The oceans also link to Canada's regions: the Atlantic Provinces, the West Coast (British Columbia) and the Northern Territories. Related test topics include Canada's five regions, the national motto, the Port of Vancouver, and the Northwest Passage explored by early navigators. Canada also has many large lakes and rivers, including the St. Lawrence, which connects the Great Lakes to the Atlantic. The Arctic Ocean is covered by sea ice for much of the year, which is why the North is so remote.
Why are the other answers wrong?
- Atlantic, Arctic and Bering: The Bering Sea is a sea between Alaska and Russia, not an ocean, and it does not border Canada.
- Hudson, Pacific and Atlantic: Hudson Bay is a large bay inside Canada, not an ocean. The missing ocean is the Arctic.
- Pacific, Indian and Atlantic: The Indian Ocean is in the Southern Hemisphere near Africa, India and Australia. It does not touch Canada.
What is the most common mistake?
Learners sometimes list Hudson Bay or the Bering Sea as oceans. These are bodies of water, but they are not oceans.
How can you remember the answer?
Use the PAA compass: Pacific on the left, Atlantic on the right, Arctic on top.
