Rules for Rainout/Inclement Weather

In the event of bad or inclement weather, the Town of Oakville may close parks. If they do, this will be posted on their website by 4pm on that day or you can call the Town of Oakville Sports Hotline at 905-338-4398. We will then notify all coaches by email (and Twitter). If there is no posting or email by 5pm, assume the game is to be played. Please go to the diamond, as the decision to cancel a game is made at the diamond, at game time, by the umpire. Teams are required to be ready to play at game time. If a team does not have enough players for the game, a forfeit is declared. If both teams do have enough players for the game (minimum 7 players), rainout rules are then applied.

Parks in the Town of Halton Hills, Milton, Burlington and Mississauga are controlled by their respective Parks & Rec departments. We will try to keep you updated on these closures as we get notified.

Check the Town of Oakville’s update page on park closures:

For the Rain-out Policy for MGSA interlock teams, click here.

If there is any sign of thunder or lightning before or during the game, the game will be cancelled immediately.

If the game has not yet started, the umpire (in consultation with the coaches) will determine if the diamond is unplayable due to unsafe field conditions, and will cancel the game. If the game has started and the field becomes unplayable, the last complete inning score is recorded for the game.

Rescheduled games may or may not be arranged. This will depend on the division and interlock circuit your team plays in. Games that are rained-out in Blastball, Tyke and Mite divisions are not rescheduled.

For practices, if you have not heard anything by 5pm, your coach will make the decision about cancelling and notify you directly.


Please read and follow the OGSA rain-out and rescheduling process for games.
