It is a lesson in what not to do in Howe Sound when whales are spotted.
In July, Fisheries and Oceans Canada implemented new regulations that require people and vessels to maintain a minimum distance of 100 metres from most whales, dolphins and porpoises to protect them from human disturbances.
A distance of 200 meters is required when approaching killer whales in B.C.
This video shows a humpback whale bumping into an inflatable tour boat off the coast of Nova Scotia. It is making waves online, just a few months after the introduction of new federal rules limiting the distance between vessels and marine mammals.
A passenger on the Zoadiac inflatable whale watching boat, posted the video from Sept. 2 showing the whale's tail suddenly rising from the water and them slamming down onto the bow of the small boat.
