It also included a lazy river and a kids area, Scooby Splash Islands, with some kiddie slides and a wading pool.

It saw Splash Works expand to 8.1 hectares (20 acres)[4] through an expansion south of the Mighty Canadian Minebuster, so much so, some of the track had to be reconfigured so a bridge could be built over it.

The 1996 expansion saw the creation of White Water Bay, which is still the largest outdoor wavepool in Canada, along with the Black Hole enclosed tube slide complex and Pump House, an interactive spray ground.

In 2016, Canada's Wonderland announced the addition of Muskoka Plunge, a quadruple drop pod slide that would replace the aging Body Blast.

On 10 August, 2023, the park announced Splash Works would receive Moosehorn Falls for the 2024 season.

In addition, Lakeside Lagoon doubled in size and introduced new interactive water features and children's slides alongside various aesthetic changes during this revamp, giving the area a more Canadian theme.
