Yes. Here's all the info you could probably possibly want:
Given the nature of shifting seasons and the unpredictability of the Canadian climate, the CFL and the Management Council comprised of Club Presidents jointly developed a comprehensive weather protocol to address in-game situations where the safety of players, officials and fans may be affected by inclement weather. The protocol was negotiated into the CFL and CFLPA?s collective bargaining agreement this past spring.
The Game Supervisor, Stadium Security Director or Head Referee may stop the game at any point, but once the game becomes official at the 7:30 mark of the third quarter, only the Game Supervisor and Head Referee may stop the game.
Each outdoor stadium is equipped with an onsite weather station to determine exact measurements and the proximity of weather systems. While the protocol is specific to nearby lightning, similar standards can be applied in cases of extreme heat, excessive downpour, dangerous hail, poor air quality, etc., as advised by the league?s meteorologist.
When lightning strikes:While active weather situations are monitored throughout gameday, the Game Supervisor and the CFL Command Centre will be notified if any lightning strikes occur within 25km of the stadium. In the event of a lightning strike within 10km, the Game Supervisor will automatically stop the game by contacting the Head Referee, who will then send teams to their dressing rooms, while notifying spectators that the game is under a weather delay.
The game may also be proactively halted if the league meteorologist foresees a weather system moving towards the stadium which would put players, officials and fans in any danger.
Regular season: Calling the gameIf there is a stoppage greater than 60 minutes after the game becomes official at the midway point of the third quarter, the game will be considered final. Two points will be awarded to the leading team, and in the event of a tie when the game is stopped, each team will receive one point.
Before the halfway point of the third quarter, if the total stoppage time is more than three hours, the game will be cancelled, and players will NOT be required to play on the following day.
Based on historical data in which the leading team went on to win 98% of games, it was determined that a team will be awarded a victory and two points, if ahead by:
21+ points in the first quarter
17+ points in the second quarter
13+ points in the third quarter
