H2O Adventure + Fitness Centre

H2O Adventure + Fitness Centre is a YMCA-run indoor waterpark billing itself as Canada's largest municipal waterpark, with waterslides, a FlowRider, wave pool, lazy river and splash park. A go-to for families on a cold or rainy day, with a hot tub and steam room for grown-ups. Drop-in is about $13 for adults, $7 for kids or $34 for a family, and under-3s swim free. Kids 7 and under must stay within arm's reach of someone 16+, adults need photo ID, and there's a pool lift.
