Report on comments to address comments on the environmental occurrences notification agreements

On October 18, 2025, a notice was published in the Canada Gazette, Part I, with respect to the availability, upon request, of the proposed environmental occurrences notification agreements (the “proposed notification agreements”) for a public consultation period of 60 days, ending on December 17, 2025.

The proposed notification agreements were developed by Environment and Climate Change Canada, and the governments of Ontario, Manitoba, British Columbia, Saskatchewan, Alberta, and Yukon.

In accordance with subsection 9(4) of the Canadian Environmental Protection Act, 1999, this report summarizes one comment received and how this comment was addressed. Several editorial changes that clarify the text of the agreements have been accepted, but are not specified in this document. No notices of objection were filed.

Response to comments

One submission was received from a member of the public as follows:

“Please, notify, immediately, every municipal animal shelter, humane society, SPCA, and wildlife rehabilitation text-center in the area, letting them know there is a spill and animals will be coming in. They also need a plan in case of a spill.”

The environmental occurrences notification agreements (agreements) are limited to establishing a streamlined notification and information-sharing system between federal, provincial, and territorial governments for environmental occurrences reported under comparable legislative and regulatory provisions.

They do not create obligations to notify, share information with, or operationally direct municipal services or non-governmental organizations.

While coordination with such groups may occur under local or provincial emergency response plans, it falls outside the legal and policy scope of the agreements. Therefore, no changes were made.

ANNEX

Summary of the assessment of the Alkyl Halides Group

Pursuant to section 68 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted an assessment of four substances referred to collectively under the Chemicals Management Plan as the Alkyl Halides Group. The Chemical Abstracts Service Registry Numbers (CAS RNs),footnote 1 the Domestic Substances List (DSL) names and the common name of these substances are listed in the table below. Bromoethane and chloroethane were identified as priorities for assessment under subsection 73(1) of CEPA.

Table: Substances in the Alkyl Halides Group
CAS RN DSL name Common name
74-96-4 Ethane, bromo- Bromoethane
75-00-3 Ethane, chloro- Chloroethane
106-94-5 Propane, 1-bromo- 1-Bromopropane
156-60-5 Ethene, 1,2-dichloro-, (E)- Trans-1,2-dichloroethene

All of the substances in the Alkyl Halides Group are synthesized commercially. In addition, bromoethane and 1-bromopropane are naturally occurring. According to the information submitted in response to a survey under section 71 of CEPA, between 1 000 kg and 10 000 kg of 1-bromopropane was reported to be manufactured in Canada in 2008. No manufacturing activity was reported for the other substances. Bromoethane, chloroethane, and 1-bromopropane were reported to be imported into Canada in total quantities of up to 1 000 000 kg in 2008, and trans-1,2-dichloroethene in a quantity of 382 744 kg in 2011. Three of the four substances in the Alkyl Halides Group (chloroethane, 1-bromopropane, and trans-1,2-dichloroethene) may be found in a number of products available to consumers, including liquid or aerosol cleaners or degreasers, aerosol starting fluids (engine starting aid), automotive air conditioning (A/C) flush, silicone mould release spray, spray foam insulation, and textile ink remover spray.

The ecological risks of substances in the Alkyl Halides Group were characterized using the ecological risk classification of organic substances (ERC) approach, which is a risk-based approach that employs multiple metrics for both hazard and exposure, with weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are based principally on metrics regarding mode of toxic action, chemical reactivity, food web–derived internal toxicity thresholds, bioavailability, and chemical and biological activity. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is used to assign a low, moderate, or high level of potential concern for substances on the basis of their hazard and exposure profiles. Based on the outcome of the ERC analysis, substances in the Alkyl Halides Group are considered unlikely to be causing ecological harm.

Considering all available lines of evidence presented in this assessment, there is a low risk of harm to the environment from the four substances in the Alkyl Halides Group. It is concluded that bromoethane, chloroethane, 1-bromopropane, and trans-1,2-dichloroethene do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.

The risk posed to human health by substances in the Alkyl Halides Group was characterized on the basis of available health effects and exposure information. Assessments from the World Health Organization, the Organisation for Economic Co-operation and Development, the International Agency for Research on Cancer, and the United States Environmental Protection Agency were used to inform the health effects characterization in this assessment.

The general population of Canada may be exposed to bromoethane primarily from indoor and ambient air. Bromoethane is not anticipated to be found in products available to consumers. For bromoethane, olfactory epithelium respiratory metaplasia of the nasal cavity and cancer were considered to be the critical effects. Based on the anticipated incremental lifetime cancer risk from exposure through air, cancer is not anticipated to present a health risk of concern. Margins of exposure between the exposure estimates and the critical effects observed in animal studies are considered to be adequate to address uncertainties in the health effects and exposure databases for the non-cancer endpoint.

The general population of Canada may be exposed to chloroethane primarily from indoor and ambient air, and from the use of starting fluid spray. For chloroethane, developmental toxicity and cancer were considered to be the critical effects. Based on the anticipated incremental lifetime cancer risk from exposure through air, cancer is not anticipated to present a health risk of concern. Margins of exposure between the exposure estimates and the critical effects observed in animal studies are considered to be adequate to address uncertainties in the health effects and exposure databases for the non-cancer endpoint.

The general population of Canada may be exposed to 1-bromopropane primarily from indoor air, and from the use of silicone mould release spray, electrical equipment cleaner spray, automotive A/C flush, and textile ink remover spray, with the primary route of exposure being inhalation. For 1-bromopropane, cancer, developmental toxicity, and neurotoxicity were considered to be the critical effects. Based on the anticipated incremental lifetime cancer risk from exposure through air, cancer is not anticipated to present a health risk of concern. Margins of exposure between the exposure estimates and the critical effects observed in animal studies are considered to be potentially inadequate to address uncertainties in the health effects and exposure databases for the non-cancer endpoint. Specifically, the margins between the exposure estimates and the developmental endpoints for the use of silicone mould release spray, electrical equipment cleaner spray, automotive A/C flush, and textile ink remover spray are anticipated to present a health risk.

The general population of Canada may be exposed to trans-1,2-dichloroethene primarily from indoor and ambient air, and from the use of textile spot removers. For trans-1,2-dichloroethene, immunotoxicity was considered to be the critical effect for chronic exposure, and developmental effects were considered to be the critical effect for acute exposures. Margins of exposure between the exposure estimates and the critical effects observed in animal studies are considered to be adequate to address uncertainties in the health effects and exposure databases for non-cancer endpoints.

The human health assessment took into consideration those groups of individuals living in Canada who, due to greater susceptibility or greater exposure, may be more vulnerable to experiencing adverse health effects. The risk of increased susceptibility during reproduction and development, as well as the risk for people living in the vicinity of commercial or industrial facilities releasing bromoethane and chloroethane (including First Nations communities), was assessed, and age-specific exposure estimates were derived. Generally, infants and children were found to have higher potential exposure to the four alkyl halide substances than adults. All of these populations were taken into consideration during assessment of the potential harm to human health.

Considering all of the information presented in this assessment, it is concluded that 1-bromopropane meets the criterion under paragraph 64(c) of CEPA, as it is entering or may enter the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

However, it is concluded that bromoethane, chloroethane and trans-1,2-dichloroethene do not meet the criterion under paragraph 64(c) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

Overall conclusion

It is therefore concluded that 1-bromopropane meets one or more of the criteria set out in section 64 of CEPA, and that bromoethane, chloroethane, and trans-1,2-dichloroethene do not meet any of the criteria set out in section 64 of CEPA.
