St. Marys Quarry to host event for the first time

On Saturday, September 1 from 10:00 a.m. to 12:00 p.m., the St. Marys Quarry will open its gates for the first time to everyone’s four-legged best friend.

The St. Marys Pooch Plunge, formerly located at Cadzow Pool, is now being hosted at Canada’s largest outdoor freshwater swimming pool. There will be music, prizes and a variety of water activities for dogs of all breeds.

Pet guardians ages eighteen and older will be able to swim with their dogs at their own risk in a portion of the swimming hole marked with buoys. The use of non-sinking toys such as balls and Frisbees will be allowed.

Owners may need to coax their canines into the Quarry as participants will enter via the steps or platform (the cliff dive will be closed for the event). Bringing a doggy lifejacket is encouraged. Lifejackets will be available for human participants.

For smaller or older dogs who find the swimming quarry too challenging, there will be a sprinkler and kiddie pool on shore. The large grassed area is perfect for a game of fetch for pooches that can be trusted off-leash.

Admission is $3 per pup with proceeds benefitting the Stratford Perth Humane Society. All dogs who participate should be up-to-date on their vaccines.
