At this incredibly difficult time, I’m sending my deepest condolences to her family, her friends, and her fellow firefighters.

"We must never forget the risks these heroes take every time they run toward the danger. To firefighters in British Columbia and across the country who are doing just that to keep us safe: Thank you. We are inspired by your courage, and grateful for your service."
