Canada’s largest outdoor pool is in Ontario and it opens for the season next month

Byng Island Conservation Area in Dunnville, Ont., is home to the largest outdoor pool in all of Canada. It’s a popular summer destination that we’re definitely looking forward to enjoying very soon. Temperatures have felt less like spring and more like fall as of late, but the conservation area is aiming to open the attraction next month. Here’s what you need to know.

It’ll take you just over an hour and a half from Toronto to reach the conservation area. Byng Island provides access to the Grand River and Lake Erie for paddling, fishing, and sailing.

It spans 140 hectares and is made up of Carolinian forests, wetlands, and creeks, according to the Grand River Conservation Authority (GRCA)

But, of course, one of the biggest highlights here is its outdoor swimming pool. It can hold up to 1,000 people and has a diving board.

In an email to Curiocity, Byng Island confirmed an opening date of June 20, 2026.

Though the pool opens later in the season, the conservation area itself is open to the public now.
