You can speed down 35 giant slides, including the "tallest waterslide tower in Canada," and enjoy 100 water games and two themed rivers.

The park is also home to the "largest" wave pool in the country that stretches the size of 3 NHL rinks.

Some of the most thrilling attractions include the Accelorators, Aqualoops and Vertigo, which offer steep drops and high-speed twists.

According to the website, "2026 is shaping up to be [the] biggest, boldest, and most exciting summer yet." The park is getting some new experiences and events, including World Cup screenings, a brand-new arcade, and new menu items.

Foam Fest will also return, featuring "music, foam, and fun for everyone."

Daily tickets and season passes are available on the park's website. You can also book add-ons like a "luxury cabana" where you can relax in the shade.

If you're looking ot make a splash this summer, Canada's largest waterpark is the place to be.
