Prime Minister Justin Trudeau says he is “heartbroken” by the news that a 24-year-old firefighter from Calgary has died while on duty in Jasper National Park.

Trudeau’s condolences are among many being posted to social media about the firefighter, who the RCMP say was based out of the Rocky Mountain House area, about 200 kilometres north of Calgary.

Police say they learned Saturday afternoon that an Alberta Wildland Fire Employee was seriously injured by a falling tree while fighting an active fire north of Jasper.
