A 62-year-old woman has been mauled to death by a black bear on a remote island in Ontario.

The tragic incident occurred on Sunday evening while the victim was staying with her Minnesota-based parents on Rainy Lake, which straddles the US- Canada border

Authorities say the woman heard her two dogs barking outside of her cabin on Red Pine Island, and went to investigate.

Her parents - aged in their 80s - called police when she failed to return a short time later.

Provincial officers from nearby Fort Frances arrived by boat around 30 minutes later and began scouring the small island.

Ontario Provincial Police Constable Jim Davis told The Star Tribune on Tuesday that it took search crews 'a while [to locate the victim] because there's a lot of underbrush and different trails'.

Eventually, they discovered a black bear standing over the woman's partially eaten remains.

Rescuers shot the bear, which was was a yearling - aged between one and two years old.

Davis said another yearling and a fully-grown female bear were spotted in a nearby bush 'making noises with their mouths and stomping'.

Ontario's Ministry of Natural Resources and Forestry will decide whether to capture or kill those two bears.

Other visitors on the island were immediately informed of the attack - which are considered extremely rare both in Ontario and in Minnesota, which is just 10 miles south from where the attack occurred.

Minnesota wildlife biologist Andy Tri told the publication that black bears 'have a natural fear of humans, and 99 times out of 100, if you come across a bear in the woods and make noise, they're going to spook off and leave'.

The incident happened on Red Pine Island, located on Rainy Lake - a body of water which crosses US and Canadian territories
