In Quebec, public swimming pools and supervised beaches are regulated by the Regulation respecting safety in public baths (Règlement sur la sécurité dans les bains publics) and the Regulation respecting water quality in swimming pools and other artificial pools.
As of 2025–2026, Quebec has significantly increased its focus on residential safety, while maintaining strict microbiological and operational standards for public facilities.
This regulation applies to any pool in a public building (municipalities, schools, hotels, or gyms) and sets the standards for design and supervision.
Supervision Rules:
Class A (Public): Must have certified lifeguards.
Unsupervised Class B (Small Hotels/Condos): If no lifeguard is present, the pool must be locked from the outside. No one under 12 years old is admitted without a guardian (18+), and a maximum of 10 people can be in the water at once.
Emergency Communications: A communication device (phone) must be within 100 meters of the surveillance station to contact emergency services (911).
Signage: Depth markings must be in a contrasting color and at least 100 mm high, located at the shallow end, the break in slope, and the deepest point.
Quebec has some of the most detailed microbiological requirements in Canada, governed under the Environment Quality Act.
Microbial Limits: The water must test at <1 CFU/100 ml for E. coli and Fecal coliforms.
Chemistry Ranges:
Free Chlorine: 0.8–2.0 mg/L (indoor); 0.8–3.0 mg/L (outdoor).
pH: Strictly 7.2 to 7.8.
Alkalinity: 60 to 150 mg/L.
Clarity: A black disc must be visible from any point on the deck 9 meters away.
Testing Logs: Operators of large public pools must collect samples for lab analysis at least every 2 to 4 weeks, in addition to daily on-site testing.
This is a major area of change. Quebec has removed the "grandfather clause," meaning all residential pools must now comply with current safety standards.
The Deadline: Owners of pools installed before 2010 were originally given until 2025 to comply, but the deadline was recently extended to September 30, 2027.
Fencing: Fences must be at least 1.2 meters high and prevent a 10 cm sphere from passing through.
Chain-Link Exception: For fences installed after 2021, the mesh must be 30 mm or less (or use slats) to prevent climbing.
Equipment Placement: Pumps and filters must be at least 1 meter away from the pool to prevent children from using them as a step to climb into the water.
Regulation respecting safety in public baths (B-1.1, r. 11): The primary legal document for public pool safety and design.
Regulation respecting water quality (Q-2, r. 39): The technical standards for chemistry and bacteria.
Residential Swimming Pool Safety (Official Guide): A plain-language guide from the Government of Quebec regarding the new fencing and gate rules.
Lifesaving Society Quebec (Société de sauvetage): The official body for lifeguard certification and aquatic safety standards in the province.
Note: In Quebec, municipal inspectors are very active in enforcing fencing permits. You must typically obtain a permit from your city hall before installing a pool or changing a fence to ensure it meets the 1.2m non-climbable standard.
