EXPLANATORY NOTE

(This explanatory note is not part of the notice of intent.)

Description

The notice of intent is an opportunity for the public to comment on the proposed amendments to the Domestic Substances List (DSL), pursuant to subsection 66(1) of the Canadian Environmental Protection Act, 1999 (CEPA), that would add the letter “P” to the identifiers of 220 polymers, as the assessed form of those polymers met the reduced regulatory requirement (RRR) polymer criteria.

Background

The DSL provides an inventory of substances manufactured in or imported into Canada on a commercial scale. A substance not on the DSL is therefore a new substance in Canada. Under CEPA, no new substances can be manufactured in or imported into Canada above the prescribed thresholds before an assessment of their potential impacts on human health and the environment has been performed. Reporting requirements for new chemicals and polymers are set out in the New Substances Notification Regulations (Chemicals and Polymers) [the Regulations].

Substances on the DSL are not subject to notification under the Regulations; however, when a substance identifier on the DSL is followed by a regulatory flag (that is letter “S,” “S′” or “P”), this substance is subject to notification under certain circumstances.

The letter “P” after a substance identifier indicates that the substance assessed and added to the DSL met the RRR polymer criteria in the Regulations. Substances that meet the RRR polymer criteria are considered of low concern, which allows for fewer regulatory information requirements under the Regulations than for non-reduced regulatory requirement (non-RRR) polymers. Typically, a substance synthesized in a form that meets the RRR polymer criteria can also be synthesized in a form that does not meet these criteria.

The purpose of the letter “P” is to indicate that any person who intends to manufacture in or import into Canada the polymer in a form that does not meet the RRR criteria in a quantity above prescribed thresholds must submit the information prescribed in the Regulations. Please consult section 4.7 of the Guidance document for the New Substances Notification Regulations (Chemicals and Polymers) for help determining the applicable notification schedule.

Project scope

Environment and Climate Change Canada identified substances that were assessed as RRR polymers and added to the DSL prior to the introduction of the letter “P” in 2003.footnote 3 Any form of these polymers that does not meet the RRR criteria currently does not require notification. Therefore, it is proposed to add the letter “P” to the identifiers of these polymers to clarify that only the RRR forms of these polymers are on the DSL, as per their assessment, and not the non-RRR forms. The addition of the letter “P” would allow for the environmental and human health risk assessment of any form of these polymers that does not meet the RRR criteria, prior to their manufacture or import in Canada.

Next steps

Within 120 days of publication of the notice of intent, any person may submit comments on the proposed amendments, which will be taken into consideration during the development of the final order. The final order will be published in the Canada Gazette, Part II. Amendments to the DSL are not in force until the order is published in the Canada Gazette, Part II.

Guidelines for Canadian drinking water quality, Chlorite and Chlorate

Pursuant to subsection 55(3) of the Canadian Environmental Protection Act, 1999, the Minister of Health hereby gives notice of the draft Guidelines for Canadian drinking water quality, Chlorite and Chlorate. The proposed guideline document is available from February 13, 2026, to April 14, 2026, and can be found on Health Canada’s Environment and workplace health consultations web page. Any person may file written comments on the proposed document with the Minister of Health within 60 days after publication of this notice. Comments must be sent by email to water-consultations-eau@hc-sc.gc.ca.

On behalf of the Minister of Health

ANNEX

Proposed guideline

The proposed maximum acceptable concentration (MAC) for chlorite in drinking water is 1 mg/L (1 000 µg/L). The proposed MAC for chlorate in drinking water is 1 mg/L (1 000 µg/L). A MAC for chlorine dioxide is not required because of its rapid reduction to chlorite and, to a lesser extent, chlorate in drinking water.

Drinking water treatment systems should make every effort to meet the guidelines; however, any method of control employed must not compromise the effectiveness of water disinfection.

Executive summary

This guideline technical document was prepared in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water and assesses all relevant information on chlorite and chlorate as well as chlorine dioxide. It also assesses the health risks associated with chlorite and chlorate in drinking water, taking into account new studies and approaches as well as available treatment technologies.

Exposure

Chlorite and chlorate are disinfection by-products of chlorine dioxide. Chlorine dioxide is an unstable gas used as a primary disinfectant or biocide in municipal water treatment and to control taste, odour and colour. Under certain conditions, hypochlorite solutions used to treat drinking water can degrade and form chlorate. Chlorine dioxide and its disinfection by-products, chlorite and chlorate, are not naturally present in the environment.

Although the use of chlorine dioxide by drinking water systems in Canada is limited, drinking water is the main source of exposure to chlorite and chlorate for the general population of Canada.

Canadian data indicate that chlorite and chlorate levels found in drinking water are generally well below the proposed MACs and are mostly below detection limits.

Health effects

Chlorine dioxide rapidly degrades to mostly chlorite, and lesser amounts of chlorate, in drinking water and is also quickly metabolized to chlorite and chlorate in laboratory animals. The health effects of chlorine dioxide are similar to those of chlorite, its major metabolite, and somewhat similar to chlorate.

In animals, chlorite adversely affected neurodevelopment and general development as well as brain and liver weights, and altered thyroid hormone levels. Chlorate mainly caused thyroid and hematological effects, with thyroid effects being the most sensitive endpoint.

Analytical and treatment considerations

The development of a drinking water guideline takes into consideration the ability to both measure the substance and remove it from drinking water supplies. Several analytical methods are available for measuring chlorite, chlorate and chlorine dioxide concentrations, both at water treatment facilities and in the field.

Drinking water systems use chlorine dioxide largely to oxidize iron and manganese, control taste and odour and reduce total trihalomethanes formation. Chlorite can be removed after formation, but chlorate is very difficult to effectively remove. Therefore, treatment strategies are focused on prevention as a best approach.

Distribution system

Although chlorine dioxide is a relatively strong disinfectant, it is not frequently used as a distribution system disinfectant.
