Ontario’s Alcohol and Gaming Commission (AGCO) ordered racetracks to cancel or postpone official workouts, qualifying events and races when the nearest Environment Canada monitoring station records an Air Quality Health Index of 7 or higher. The directive, issued by order of Deputy Registrar Tyler Durand, remains in force until the Registrar directs otherwise.
The province-wide threshold requires racetracks to cancel or postpone specified activities when air quality reaches the high-risk level.
