A 24-year-old Calgary man is dead after being injured by a falling tree while fighting a wildfire northeast of Jasper, Alta.

RCMP say they were notified of the incident on Saturday at 2:15 p.m. MT. The firefighter was taken by STARS air ambulance to hospital, but was not able to be saved.

"RCMP wish to express our heartfelt condolences to the family, friends and co-workers of the deceased," said Alberta RCMP in a release issued late on Saturday night.

The man — who RCMP say was part of the Rocky Mountain House Fire Base — was among hundreds of firefighters who are in Alberta to fight the massive wildfires affecting the province..
