We used to pack bear spray when we camped in Algonquin in the early 90's. A lot of campers did back then I think because of this incident...

While they were setting up camp on Bates Island, a black bear broke both of their necks. The bear then dragged their bodies into the woods and consumed the remains. When police arrived five days later, the bear was guarding the bodies. A park naturalist called the attack "right off the scale of normal bear behavior".
Our camp was checked out by a bear one night at around 2 am which was kinda scary even though we'd done everything by the book - food tied up off the ground, etc.
