A leak in the main pool at the Windsor International Aquatic and Training Centre has shut down the natatorium for at least five days.
The City of Windsor said the closure starts at 5 p.m. on Saturday and it hopes to fix the leak quickly.
The pool needs to be partially drained.
The city will let the public know when the pool will reopen.
Meanwhile, the closure will not impact operations at the Windsor International Aquatic and Training Centre fitness centre or Adventure Bay Family Water Park.
