Regarded by some as the "unofficial capital" of Alberta, Calgary is the province's largest city and Canada's fifth largest central metropolitan area. Driven by the growth of the energy sector, the city has seen a boom in population and urbanization in recent years. Calgary's political landscape was shaken up by the mayoral election of Naheed Nenshi, Canada’s first Muslim mayor. The city is synonymous with rodeos, cowboys, and theme rides thanks to the annual Calgary Stampede. It's also home to the Calgary Flames NHL team and the CFL's Calgary Stampeders.
