Mr. Aaron Gibbons, aged 31, was on Sentry Island, a popular fishing and hunting spot on the west coast of Hudson Bay, when he was faced by the bear on 3 July.
A man and father died protecting his children in Canada’s northernmost territory of Nunavut in a rare polar bear attack.
The children were unhurt, but Mr Gibbons died in the attack although another adult later shot and killed the bear.
Mr. Gibbons was enjoying his day with his children, Gibbon’s uncle Gordy Kidlapik told the Canadian media. They were surprised by a bear that had started to stalk and charge towards one of his children.
The father was unarmed at the time, police said, even though he would have had a rifle with him on the outing.
His relative said he “died a hero”, telling his daughters to run while he put himself between them and the bear.
One of the girls, of a primary school age, called for help through the boat’s radio.
Mr Gibbon’s death has shocked his hometown of Arviat, about 10km from the site of the attack, which has grown accustomed to seeing polar bears as they migrate north.
A local lawmaker named John Main said on Canadian broadcaster CBC, that the incidence is a really incredibly sad one.
It is a small community and when something like this happens, it affects the whole community.
There have been sightings of 380 polar bears in the hamlet 2017, the predominantly Inuit community has become increasingly concerned for public safety.
The last death from a polar bear attack in Nunavut was in 2000, about 200km (124 miles) up the coast from Arviat in Rankin Inlet, local authorities said.
