Parks and Public Spaces Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

In Mississauga, Ontario, maintaining safe chlorine levels and documented testing at public pools and aquatic facilities is a shared responsibility between the City and public health authorities. This guide explains who enforces chlorination and testing, what records and actions operators must keep, common violations, and how to report concerns for pools in parks, community centres and other public spaces.

Overview of Legal Framework

Public pool water quality in Mississauga is governed by provincial public health regulation and local operating policies. Facility operators must follow provincial standards and cooperate with regional public health inspections. For local details and facility listings see the City of Mississauga aquatics information City of Mississauga aquatics[1]. For public health inspection and enforcement responsibilities see Peel Public Health guidance on pools Peel Public Health pools[2]. The controlling provincial instrument is the Public Pools regulation under the Health Protection and Promotion Act Ontario Regulation 565/90[3].

Key Operational Requirements

  • Operators must monitor water chemistry and maintain written records of tests and corrective actions.
  • Testing frequency and required parameters are set by provincial regulation and guidance; consult the provincial regulation and local public health for exact schedules.
  • All public pools must display or make available operator contact information and inspection history on request.
Keep daily logbooks and site test strips or probe calibration records on file for inspections.

Penalties & Enforcement

Enforcement is primarily undertaken by Peel Public Health for health-related standards and by City of Mississauga staff for facility compliance and related bylaws. Specific monetary fines or daily penalties for chlorination or testing breaches are not specified on the cited municipal or regional pages; see the cited provincial and regional sources for enforcement procedures and orders.[2][3]
