A young firefighter has died battling the flames of a wildfire in British Columbia as wildfires rage across the Canada.

According to the General Workers’ Union of British Columbia the female firefighter was killed late Thursday night while fighting a blaze outside the town of Revelstoke, about 500 kilometers northeast of Vancouver. The Mounted Police of that city reported that the 19-year-old was in an isolated area where a small fire had broken out. She lost contact with her team and became stranded when a tree crushed her. She was airlifted to a hospital but succumbed to her injuries.

“The news from British Columbia that a female firefighter who bravely fought the fires has lost her life is heartbreaking. At this difficult time, my condolences to her family, friends and colleagues,” Canada’s prime minister tweeted Justin Trudeau.

Canada is experiencing perhaps the worst wildfires in its history, and particulate matter emissions have reached record levels.

In the Quebec army has been deployed to help evacuate communities in the north of the province, emergency response minister Bill Blair has announced.

In British Columbia, about 2,000 firefighters are battling more than 350 fires. Authorities have called for an additional 1,000 firefighters to be sent to the area to help with the effort. Since the beginning of the year, 12 million hectares of forest have been cleared in this province alone, an area far greater than the average of the decade, which is 760,000 hectares of burnt area per year.

High temperatures are forecast to continue in British Columbia. The situation is exacerbated by a lack of rainfall, with authorities noting that the drought has reached “unprecedented” levels this year.
