A large wildfire burned through Slave Lake, Alberta, Canada and its surrounding area from May 14 to 16, 2011. The conflagration, which originated 15 kilometres (9.3 mi) outside of town as a forest fire, was quickly pushed past fire barriers designed to protect the town by 100-kilometre-per-hour (60 mph) winds. The fire forced the complete evacuation of Slave Lake's 7,000 residents—considered the largest such displacement in the province's history at the time—to the nearby towns of Athabasca and Westlock, as well as the provincial capital of Edmonton. No casualties were reported amongst the town's population, but a pilot was killed when his helicopter crashed while he was battling the fires around the community.
