I thought it would be helpful to show this summary (via Wikipedia) that some may have already seen…
Tiger-Cats lead the series 36 – 14 – 1
Tiger-Cats Longest Winning Streak: 7 (2014–2021)
Argos Longest Winning Streak: 3 (1994–1997, 2006–2008)
Tiger-Cats and Argos did not play on Labour Day in the following 22 years:
1962, 1965, 1966, 1969, 1970, 1972–1974, 1976, 1977, 1979,
1981–1986, 1990, 1995, 2011, 2013, 2020
Due to scheduling conflicts, the Tiger-Cats temporarily revived its rivalry with the current incarnation of the Alouettes in the Labour Day game for the 2011 season; the change in opponents led Hamilton to dub the game the Labour Day Classique in reference to Montreal’s francophone community. Therefore, in 2011, this automatically resulted in Toronto and BC facing each other.
In 2013, the Tiger-Cats’ did not host a game on Labour Day for only the second time in franchise history (the first being 1995). It was also the first time that they did not host a game on that weekend. Because Ivor Wynne Stadium was demolished to make way for the new Tim Hortons Field, the team played out of Alumni Stadium in Guelph. The University of Guelph Gryphons (along with most Ontario University Athletics teams) were playing that same day, so the Tiger-Cats could not host the game. To make up for it, the Toronto at Hamilton matchup was played in the Thanksgiving Day Classic.
For the 2016 contest, to avoid any further conflicts with OUA games, the CFL moved the Toronto/Hamilton matchup to prime-time Labour Day evening. That year, the OUA’s McMaster Marauders football team moved its Labour Day matchup with the Toronto Varsity Blues football squad to Tim Hortons Field, creating a doubleheader with a series of concerts in-between games. This was moved back to a 1:00 pm Eastern start in 2019.
