One man is dead after a canoe carrying five men capsized on the St. Lawrence River near Quebec City around noon Wednesday. 

The incident happened on the water near l'Anse au Foulon, southwest of the Plains of Abraham. 

The man, 39, was caught in the current and was in the water for nearly 30 minutes before being pulled out by a team of rescue divers from the Quebec City fire department. He was unconscious when he was pulled from the water, according to Radio-Canada.

The fire department said that man was transported to a nearby hospital. He was treated for hypothermia and later died.

The other four people who'd been aboard the boat were helped by port workers who saw the canoe capsize.

"We called 911 and warmed them," said witness Sylvain Chassé.

It is not yet known what caused the boat to capsize.
