Canada Environmental Protection Act and the Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270)
What is the Canada Environmental Protection Act?
Reporting Obligations Under CEPA
CEPA compliance involves more than restrictions. CEPA also uses information-gathering and reporting tools, such as notices and surveys, that can affect many organizations.
Section 46 CEPA - Plastics Survey
Section 71 CEPA - Annual Declarations of Chemicals
Introduction to the Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270)
The Prohibition of Certain Toxic Substances Regulations, 2025 target some of the most harmful substances—often persistent and bioaccumulative—by prohibiting core commercial activities involving those substances and certain products that contain them.
When do the 2025 Regulations apply?
The Regulations apply to toxic substances that are:
- on the CEPA Schedule 1 toxic substances list, and
- listed in Schedule 1 of SOR/2025-270 (and to products containing them).
SCCPs Restriction (Chlorinated Alkanes C10–C13)
Short-chain chlorinated paraffins (SCCPs; chlorinated alkanes with 10 ≤ n ≤ 13) appear in Schedule 1. The Regulations create a narrow authorized activity pathway focused on the use or sale of products manufactured in Canada or imported before March 14, 2013.
This date-based structure helps manage legacy products while blocking reintroduction through ongoing manufacturing or importing.
PFOS, PFOA, LC-PFCAs, PBDEs, HBCD and why the 2025 Regulations matter
The 2025 Regulations continue to address substances that persist and bioaccumulate—and that show up across electronics, plastics, textiles, foams, and industrial applications. Federal registry information indicates that the 2025 framework also tightens controls for several already-managed substances by removing or limiting certain activities.
Prohibition of Certain Toxic Substances Regulations, 2025 (SOR/2025-270)
The 2025 Regulations maintain and strengthen controls on substances Canada describes as among the most harmful. They cover substances that Canada restricted for many years and substances that Canada prohibited more recently, sometimes with limited exemptions for critical uses.
In product compliance work, supply chains commonly encounter:
PFOS
PFOA
Long-chain PFCAs (LC-PFCAs)
PBDEs
HBCD
and other flame retardants referenced in federal materials (e.g., DBDPE and Dechlorane Plus).
A key operational point: the Regulation’s Schedule 1 defines whether each substance triggers a prohibition or an authorized activity—and it adds conditions and time limits substance-by-substance. As a result, two companies may both face “PBDE risk” but see different compliance outcomes depending on:
product category (EEE vs. other manufactured items),
whether the substance is intentionally used or present only in trace amounts, and
any applicable conditions or time limits.
Why does CEPA regulate PFAS under the Prohibition of Certain Toxic Substances Regulations?
PFASs are Used Virtually Everywhere
PFAS are a large group of human-made chemicals valued for their resistance to water, oil, and heat. PFAS may be present across many product categories, for example:
Three well-known PFAS examples historically managed under CEPA frameworks include:
- PFOS (perfluorooctane sulfonate),
- PFOA (perfluorooctanoic acid), and
- Long-chain PFCAs (LC-PFCAs).
Environmental Concerns with PFAS
Many people call PFAS “forever chemicals” because many PFAS persist in the environment. CEPA’s approach typically combines information-gathering (e.g., section 71 notices) with risk management instruments such as prohibition regulations.
They are known as “Forever Chemicals” due to their persistently long life in the environment. They are classified as PBTs and raise considerable environmental concerns. Furthermore, scientists have detected PFASs in drinking water, municipal wastewater, and landfills.
Therefore, the Government of Canada has prohibited these dangerous substances through various regulations, including the previously mentioned Prohibition of Certain Toxic Substances Regulations, 2012.
Polybrominated diphenyl ethers (PBDEs)
PBDEs are brominated flame retardants. Various products have historically contained PBDEs, including:
Hexabromocyclododecane (HBCD)
Decabromodiphenyl Ethane (DBDPE)
DBDPE is an additive flame retardant that can be used in plastics, rubber materials, and certain electrical/electronic applications. Federal materials describing the 2025 framework identify DBDPE among substances addressed under the prohibition regulations approach.
Dechlorane plus (DP)
Beyond CEPA
Depending on product type and sector, other Canadian regulations may also apply—such as energy efficiency requirements and other federal or provincial obligations.
