Football does not do weather cancellations. As they say, neither rain, nor snow, nor gloom of night stays these mighty ballcarriers from the swift completion of their appointed runs. However, football games are delayed occasionally due to scheduling conflicts, lightning, faulty lighting systems, or other issues that cause games to stretch across two days.
Thanks for the heads up. While I will watch the EDM-SSK game tonight, there are many gaps in my CFL knowledge. I was aware of the 1962 game but not that it extended over two days. I'll add it as a follow-up to this post. Hopefully, others mention additional games worth covering.
In 1998, there was the Blackout Bowl between the Laval Rouge et Or and Concordia Stingers of the Ontario-Québec Intercollegiate Football Conference (O-QIFC). The teams met in the Dunsmore Cup conference championship game in mid-November, and the game was broadcast on TSN. But it was suspended on account of darkness with the game tied 10-10 after regulation time. It was around 5 p.m. ET, and it can be pretty dark by that time of day in Montréal in the fall.
Ironically, Concordia had a nearby sports field that was lighted, but did not have proper goalposts. The teams reconvened the next day, with Concordia winning 17-12 on the margin of a scoop-and-score touchdown.
Of course, the 1962 Grey Cup was a two-game affair due to fog. Because the game was broadcast on ABC the CFL commissioner was reluctant to cancel it due to fog - so they started the game but had to postpone it when you couldn't see anything.
