The Tigers and Wildcats amalgamated in 1950 to form the Hamilton Tiger-Cats that would compete in the IRFU. Under the guidance of prominent and distinguished local leaders such as Ralph “Super-Duper” Cooper and F.M. Gibson, it was decided that the two teams should merge as one that would represent Hamilton. Cooper was named team president and Carl Voyles served as head coach and general manager. A contest was held among the fans to determine the colors for the newly formed football club; the result was a combination of the two clubs’ colors: yellow, black, red, white and blue. Over the years, the colors have evolved to gold, black and white and remain to this day. In 1950, the Hamilton Tiger-Cats began playing in Ivor Wynne Stadium, until 2012 after which it was demolished and replaced with a new stadium on the same site, Tim Hortons Field, in 2014.

Grey Cup 1953

The 41st Grey Cup game was the Canadian Football Championship in 1953. Hamilton Tiger-Cats defeated Winnipeg Blue Bombers 12-6 at Toronto’s Varsity Stadium in a game which ended on a controversial pass incompletion.

Grey Cup 1957

The 45th Grey Cup was the Canadian Football Council’s (CFC) championship game of the 1957 season, which was played on November 30, 1957. The Hamilton Tiger-Cats defeated the Winnipeg Blue Bombers 32–7 at Varsity Stadium in Toronto.

This was the first Grey Cup game to be covered on coast-to-coast television.

The game is famous for a play in which Hamilton defensive back Ray Bawel intercepted a Winnipeg pass and raced unopposed for an apparent touchdown. As he passed the Winnipeg bench, however, Dave Humphrey, a Toronto fan who was standing in front of the Winnipeg bench, put his foot out and tripped Bawel. After the officials huddled together for a while to discuss the situation not covered by the rulebook, referee Paul Dojack assessed a penalty of half the distance to the goal line as a sort of compromise. As it turned out, the incident had little effect as Hamilton scored on the ensuing drive and the game ended in a 32–7 rout for Hamilton.

Grey Cup 1963

The 51st Grey Cup took place on November 30, 1963, at Empire Stadium in Vancouver, British Columbia, and decided the Canadian Football League (CFL) champion for the 1963 season. The Hamilton Tiger-Cats defeated the BC Lions 21-10, in front of 36,545 spectators. The game is best remembered for a controversial sequence involving American players Angelo Mosca and Willie Fleming. Mosca was accused of kicking Fleming’s head while the latter laid on the field. Fleming would leave the game, leading to a long-standing grudge between alumni of both teams.
