The Toronto Maple Leafs (officially the Toronto Maple Leaf Hockey Club) are a professional ice hockey team based in Toronto, Ontario.
 They are members of the Atlantic Division of the Eastern Conference of the National Hockey League (NHL).
 The club is owned by Maple Leaf Sports & Entertainment, Ltd. and are represented by Chairman Larry Tanenbaum.
 With an estimated worth of US $1.1 billion in 2016 according to "Forbes", the Leafs are the third most valuable franchise in the NHL, after the Montreal Canadiens and the New York Rangers.

The Toronto St. Patricks were a professional men's ice hockey team which began playing in the National Hockey League (NHL) in 1919.
 The Toronto NHL franchise (league membership) had previously been held by the Arena Company (and the team called the "Arenas"), but despite winning the Stanley Cup the team was bankrupt and pulled out of the league after just two seasons.
 The rights to the Toronto franchise was purchased by a group of investors with links to an amateur club called the "St. Patricks".

 J.P. Bickell invested in the St. Patricks in 1924 as a favor to Charlie Querrie.
 In 1927, Charlie Querrie and other investors wanted out, J.P. Bickell made arrangements for other Toronto investors and initially hired Mike Rodden the Referee and sports writer to run the hockey operations, which didn't work out.
 He then hired Conn Smythe as the Managing Partner.
 The team was then renamed the Toronto Maple Leafs for a number of reasons, two of which are the Maple Leaf was an unofficial Canadian national symbol and secondly it was the name of the Toronto Maple Leaf Baseball Club 1896-1967.
 They played from Maple Leaf Stadium since 1926.

The flag of Manitoba is a variation of the Red Ensign which bears the shield of the provincial coat of arms.
 This flag was approved by the passage of a bill in the Manitoba Legislative Assembly on May 11, 1965 and was officially proclaimed on May 12, 1966.
 Queen Elizabeth II gave permission for the use of the Union device the preceding year (October 1965).
 The decision to adopt the flag was made after the federal government decided to replace the Canadian Red Ensign with the Maple Leaf flag, which was quite controversial at the time.
 The Manitoban flag, intentionally designed to resemble the Canadian red ensign, was seen as a way of preserving heritage that some felt was lost when the national flag was changed.
 The flag of Ontario was adopted under similar circumstances.
