=== Severe weather ===
In the CFL, a game must be delayed if lightning strikes within {{convert|10|km|mi|sigfig=1|abbr=on}} of the stadium or for other severe weather conditions, or if dangerous weather is anticipated. In the regular season, if play has not resumed after 1 hour and at least half of the third quarter has been completed, the score stands as final;<ref name="weather">{{cite web| title=CFL Weather Protocol| url=https://www.cfl.ca/weather/| access-date=2019-08-10| publisher=CFL}}</ref> this happened for the first time on August 9, 2019, when a Saskatchewan–Montreal game was stopped late in the third quarter with the score having been finalized where it stood at the time of stoppage: {{nowrap|17–10}} in favor of Saskatchewan.<ref>{{cite news| url=https://leaderpost.com/sports/football/cfl/saskatchewan-roughriders/saskatchewan-roughriders-game-versus-alouettes-delayed-by-thunderstorm| publisher=Regina Leader-Post|title=Saskatchewan Roughriders defeat Montreal Alouettes 17–10 in storm-shortened game versus Montreal Alouettes| date=2019-08-09| access-date=2019-08-10}}</ref>

If the stoppage is earlier in the game, or if it is a playoff or Grey Cup game, play may be stopped for up to 3 hours and then resume. After 3 hours of stoppage, play is terminated at least for the day. A playoff or Grey Cup game must then be resumed the following day at the point where it left off.<ref name="weather"/>

In the regular season, if a game is stopped for 3 hours and one team is leading by at least a certain amount, then that team is awarded a win. The size of lead required is 21, 17, or 13 depending on whether the stoppage is in the first, second, or third quarter respectively. If neither team is leading by that much and they are not scheduled to play again in the season, the game is declared a tie.<ref name="weather"/>

If a regular-season game is stopped for 3 hours and neither team is leading by the required amount to be awarded a win, but the two teams are scheduled to play again later in the season, then the stopped game is decided by a "two-possession shootout" procedure held before the later game is started. The procedure is generally similar to overtime in the CFL, with two major exceptions: each team must play exactly two possessions regardless of what happens; and while the score from the stopped game is not added to the shootout score, it is used instead to determine the yard line where each team starts its possessions, so the team that was leading still has an advantage.<ref name="weather"/>
