From Daily Mail:
Richard Wesley, from Hearst, Ontario, recorded the moment he was hunting in Fire River when he was charged down and attacked by a large black bear. Wesley's video, which he uploaded on Monday, starts by showing the bear meandering around and seemingly unaware he was nearby. But as the bear begins walking towards where he is, Wesley - who is holding a bow - attempts to scare the animal off by standing up and making a loud noise. He then starts backpedaling while continuing to shout, but the bear is undeterred and charges straight for Wesley. It then makes a terrifying leap directly at Wesley, seemingly at about shoulder or neck height.
The man was not harmed.
