The Toronto Maple Leafs (officially the Toronto Maple Leaf Hockey Club and often simply referred to as the Leafs) are a professional ice hockey team based in Toronto, Ontario. They are members of the National Hockey League's Atlantic Division in the Eastern Conference. The club is owned by Maple Leaf Sports & Entertainment, Ltd. and are represented by Chairman Larry Tanenbaum. With an estimated value of US $1.4 billion in 2017 according to Forbes, the Maple Leafs are the second most valuable franchise in the NHL, after the New York Rangers. The Maple Leafs' broadcasting rights are split between BCE Inc. and Rogers Communications. For their first 14 seasons, the club played their home games at the Mutual Street Arena, before moving to Maple Leaf Gardens in 1931. The Maple Leafs moved to their present home, Scotiabank Arena (originally named the Air Canada Centre) in February 1999.
The club was founded in 1917, operating simply as Toronto and known then as the Toronto Arenas. Under new ownership, the club was renamed the Toronto St. Patricks in 1919. In 1927 the club was purchased by Conn Smythe and renamed the Maple Leafs. A member of the "Original Six", the club was one of six NHL teams to have endured through the period of League retrenchment during the Great Depression. The club has won thirteen Stanley Cup championships, second only to the 24 championships of the Montreal Canadiens. The Maple Leafs history includes two recognized dynasties, from 1947 to 1951; and from 1962 to 1967. Winning their last championship in 1967, the Maple Leafs' 50-season drought between championships is the longest current drought in the NHL. The Maple Leafs have developed rivalries with three NHL franchises, the Detroit Red Wings, the Montreal Canadiens, and the Ottawa Senators.
The Maple Leafs have retired the use of thirteen numbers in honour of nineteen players. In addition, a number of individuals who hold an association with the club have been inducted in the Hockey Hall of Fame.
