YYC Calgary International Airport is one of Canada's busiest airports, serving as a major hub for western Canada. While vitally important to Calgary's economy and connectivity, the airport is not operated by the City of Calgary—it is managed by the Calgary Airport Authority, a non-profit corporation that leases the land from the federal government. Municipal-airport relations involve land use planning around the airport, transportation connections, noise management, and economic development coordination. The airport significantly impacts Calgary's position as a business centre and gateway. Municipal planning must address airport expansion, surrounding development, and transportation access.
