Ontario Pool, Spa & Waterpark Safety Sign Requirements — Public Health

Every public pool, spa, hot tub, splash pad, and waterpark in Ontario must comply with signage requirements under O. Reg. 565 (Public Pools) made under the Health Protection and Promotion Act, R.S.O. 1990, c. H.7. Local public health units conduct regular inspections, and non-compliant facilities face closure orders, fines, and mandatory corrective action. With Niagara Region home to dozens of public pools, hotel pools, waterparks, and splash pads — including major attractions like Fallsview Indoor Waterpark and Great Wolf Lodge — these requirements affect hundreds of businesses.

Who Must Comply

Under O. Reg. 565, Section 1, the regulation applies to:

• Class A pools: Public pools operated by municipalities, hotels, motels, condominiums, apartment buildings, or any entity where the public or residents have access
• Class B pools: Pools at clubs, schools, and facilities with restricted membership
• Whirlpools/hot tubs: All public whirlpools and hot tubs
• Wading pools: Including splash pads and spray pads
• Waterparks: All water slides, wave pools, lazy rivers, and interactive water features open to the public

Private residential pools serving only the homeowner's family are not covered by O. Reg. 565, but are subject to municipal fencing by-laws under the Municipal Act, 2001.
