The surfers, catching waves off the beaches of Tofino, were chased out of the water by a pod of orcas numbering at least a dozen.
At first the orcas can be seen lazily hunting their prey – seals and sea lions – but as the camera pans to the right, a handful of surfers are spotted riding the swells right off the rocky coast.
As the videographer laughs, the surfers notice the orcas, and make their way back to shore.

British Columbia is known for its vast Pacific Ocean vistas, and its stunningly beautiful natural environment. Much of the province is wild or semi-wild, and includes 141 ecological Reserves, 35 provincial marine parks, 7 provincial heritage sites, 6 national historic sites, 4 national parks and 3 national park reserves.
Wild orcas are huge, though despite being called "killer whales", they are not known for attacking humans.
They tend to feed exclusively on fish and other marine mammals such as seals, sea lions, walruses and other large whales.
