The Labour Day Classic is a particular week of the Canadian Football League (CFL) schedule that is played over the Labour Day weekend (which includes the first Monday in September). Labour Day weekend, roughly 10 weeks into the CFL season, is known for its matchups that do not change from year to year, unlike other "rivalry" weeks of the CFL schedule (with the exception of the BC–Montreal game which took place during the absence of Montreal's traditional rival Ottawa; both the Rough Riders and Renegades played in it). Labour Day weekend is also only one of two weeks (the Thanksgiving Day Classic being the other) in the CFL schedule that the league plays on a Monday. Mark's Work Wearhouse is the presenting sponsor of the event as of 2014.
