Fort McMurray, Alberta, unincorporated population centre, population 61,374 (2011c), 47,705 (2006c). Fort McMurray is the largest community in the Regional Municipality of Wood Buffalo (RMWB). It is technically known as the municipality’s “Urban Service Area” and colloquially known as “Fort Mac.” The community located near the confluence of the Athabasca and Clearwater rivers in northeastern Alberta, near the centre of the vast Athabasca oil sands deposit. Originally incorporated as a city in 1980, in 1995 Fort McMurray merged with much of the surrounding area — collectively known as Improvement District No. 143 — to create the RMWB. At 63,783 km2, the municipality is the largest in North America in terms of size, accounting for nearly 10 per cent of the province’s total area. In May 2016, Fort McMurray experienced one of the worst forest fires in Canadian history. More than 80,000 residents were evacuated and approximately 2,400 structures — about 10 per cent of the city — were destroyed.
