Sharks in Canada

As Canada is surrounded by three different oceans – specifically the Arctic, the Atlantic, and the Pacific – there are quite a few unique shark species that call the Great North their home. They can be as small as the brown catshark to as large as the basking shark, the second-largest fish in the sea. Other species seen include the blue shark, the shortfin mako shark, the common thresher shark, the porbeagle shark, and the salmon shark.
