The 1909 Canadian football season was the 18th season of organized play since the Canadian Rugby Union (CRU) was founded in 1892 and the 26th season since the creation of the founding leagues, the Ontario Rugby Football Union (ORFU) and the Quebec Rugby Football Union (QRFU) in 1883. The season concluded with Toronto Varsity defeating Toronto Parkdale in the 1909 Dominion Championship game. This year was notable for being the first year that the champions were awarded the Grey Cup trophy, although it was not delivered to the University of Toronto until March 1910.
