Canada Gazette, Part I, Volume 160, Number 25: GOVERNMENT NOTICES
DEPARTMENT OF THE ENVIRONMENT
Summary
This Canada Gazette notice does two main things. First, it removes five specific substances from the Non-domestic Substances List (meaning they are being treated as domestic substances in Canada). Second, it publishes a health and environment assessment of 13 titanium-containing substances and states that the ministers propose to take no further action on those 13 substances at this time.
What it does
1) Amends the Non‑domestic Substances List by deleting five Chemical Abstracts Service (CAS) numbers (623-53-0; 34398-05-5; 73038-32-1; 91001-61-5; 2561414-35-3). The amendment will come into force on the same day another related order (Order 2026-87-07-01 amending the Domestic Substances List) comes into force. 2) Publishes a summary of a scientific assessment of a group of 13 titanium-containing substances (including titanium dioxide, rutile, titanium tetrachloride and others). The assessment concluded these substances do not meet the legal criteria for action under the Canadian Environmental Protection Act (CEPA), and the Ministers of Environment and Health propose to take no further action now.
Who it affects
Chemical manufacturers and importers of the five substances removed from the Non‑domestic List. Companies that make or use the 13 titanium-containing substances (for example in paints, coatings, cosmetics, food packaging, electronics, adhesives, textiles and some food additives). Environmental and public‑health groups, and members of the public concerned about titanium dioxide and related compounds (especially parents of young children or people living near industrial sites).
Why it matters
Moving substances off the Non‑domestic List changes how they are classified under Canada’s chemical rules. That can affect reporting and the government’s next steps for monitoring or managing them. The titanium assessment says current levels of exposure in Canada are unlikely to harm the environment or human health. That means regulators are not planning immediate controls on those 13 titanium substances, though the assessment notes areas of uncertainty (for example inhalation effects seen in animals) and identifies food as a major source of exposure. The full assessment is available on Canada.ca for anyone who wants the technical details.
