The Canadian Pest Management Regulatory Agency (PMRA) oversees a range of disinfectants, including those used for swimming pools, spas, water treatment, and air disinfection. Additionally, device that controls microorganisms through physical methods—such as chlorine generators, copper ion generators for pools and spas, ultraviolet (UV) radiation devices, and ozone-based systems—also falls under PMRA’s regulatory scope.

Swimming Pool Disinfectants: Chlorine Products Dominate with Focus on Domestic Use

In 2025, the PMRA approved 23 swimming pool disinfectant and algaecide products, with chlorine-based products dominating the approvals. The approved products include formulations containing active chlorine in various forms, such astrichloro-s-triazinetrione , calcium hypochlorite, sodium dichloroisocyanurate, and sodium hypochlorite. Notably, 20 of these approvals were for domestic use, aligning with PMRA’s regulatory direction for common disinfectant products.

Under Canada’s Pest Control Products Act (PCPA), disinfectant formulations containing the following active ingredients may be sold without registration, provided they meet specific requirements such as toxicology classification, packaging, and sourcing from registered technical-grade products.

Key Active Ingredients and Concentrations for Pool and Spa Use

Note: Products must be formulated using registered technical-grade active ingredients and comply with PMRA’s packaging and toxicity requirements.

Regulatory Proposal for Pest Control Devices

On March 7, 2025, the PMRA introduced a regulatory proposal under the PCPA targeting pest control devices. The aim of this proposal is to reduce regulatory burdens while maintaining high health and environmental protection standards. This initiative may encourage more disinfectant device manufacturers to enter the Canadian market. The proposal, which has completed public consultation and is undergoing regulatory revisions, outlines different regulatory approaches for various types of disinfectant devices.

Proposed Regulatory Approaches for Disinfectant Devices

Note: The public consultation on this proposal has now concluded and the revision of regulatory oversight is underway.
