The Air Canada Centre is a multi-purpose arena located on Bay Street in downtown Toronto, Ontario. It is the home of the Toronto Raptors of the National Basketball Association, the Toronto Maple Leafs of the National Hockey League, and the Toronto Rock of the National Lacrosse League. It was also home to the Toronto Phantoms of the Arena Football League during their brief existence. The arena is popularly known as "the ACC" or "the Hangar" (the latter nickname coming from its sponsorship by Canada's biggest airline).

From its initial design to completion it revolutionized many concepts now included in new arenas and stadiums such as luxury suites accessible on the ground floor, splitting the main scoreboard into several sections, rotating all sponsor signage in the bowl at once (to allow dominant messaging), and multiple restaurants in and out of the main arena bowl view.

The arena is owned by Maple Leaf Sports & Entertainment Ltd., the same group that owns both the Leafs and Raptors, and is 665,000 square feet (62,000 m²) in size. Air Canada Centre is connected to Union Station and the underground pedestrian PATH system, providing easy access to public transportation (TTC, subway and GO Transit) for fans attending events. There are also 13,000 parking spaces within immediate walking distance.

Since opening, Air Canada Centre has been recognized with more than 25 industry awards that range from Canadian Major Facility of the Year (multiple times), the U.S. based Facilities & Event Management Magazine's Prime Site Award, the Wine Spectator, VQA Restaurant and the International (Diamond Wine Award) Awards of Excellence, and Tourism Toronto's Jeff Adams Access Award of Excellence for the facilities accessibility.

Air Canada Centre remains the only arena in North America to house three of its own exclusive award-winning restaurants -- The Platinum Club, Air Canada Club and Hot Stove Club. The restaurants, along with themed concessions stands and kiosks offer a diversity of food and beverages that capture Toronto's multicultural flavour. Two in-house bars, the Ice Box and Rickard's Brewhouse (which has its own micro-brewery) are favourite spots for fans before and during games.

Andy Frost is the public address announcer at the ACC during Toronto Maple Leafs home games, while Herbie Kuhn does the job for the Toronto Raptors, and Bruce Barker is the announcer for Toronto Rock games.
