What 3 oceans border Canada?
Atlantic, Pacific, Arctic
Including territories, I believe only 2 countries border 4/5 oceans (the most), but I believe no country borders all 5 oceans. The two countries are the United Kingdom and France, who both border all oceans but the Arctic. But by integral parts alone, 3 countries border 3/5 oceans. They are Russia, Canada, and the United States. (who all border the Atlantic, Pacific, and Arctic Ocean)
