What this list is
Health Canada's Cosmetic Ingredient Hotlist is an administrative list, not a regulation. It names substances Health Canada considers may not comply with the Food and Drugs Act — which is a different kind of statement from an EU annex entry.
- 580 Canadian records: 490 prohibited, 90 restricted.
- The Hotlist is administrative guidance; the binding instrument is the Food and Drugs Act and the Cosmetic Regulations.
- It is published in English and French, and both versions are official.
- The Hotlist is shorter than the EU annexes by design — it is not an attempt at the same coverage.
The Hotlist reads like a prohibited-substance annex and works differently. Health Canada publishes it as administrative guidance: it names substances that the department considers may contravene the general prohibition in the Food and Drugs Act, or the Cosmetic Regulations made under it. The legal force sits in those instruments, not in the list, and the list can be updated without the process an annex amendment would need.
For anyone comparing markets, that difference matters more than it first appears. An EU Annex II entry is a legal prohibition with a number and a date. A Hotlist entry is Health Canada saying, in advance, how it reads the Act. The practical effect on a product is usually the same, but the reasoning a regulator will accept — and the evidence that can rebut it — is not.
The list is also much shorter than its EU counterpart: 580 records against several thousand. That is not a gap waiting to be filled. Canada regulates cosmetics through a general safety duty plus this list, rather than through an exhaustive catalogue, so a substance being absent from the Hotlist says nothing about whether it is acceptable in a Canadian product.
Both the English and French versions are official. Where a substance is named differently between them, neither wording is a translation of the other for legal purposes.

How Canada differs from other markets
Comparing this market's imported rules against every other market's for the same substance. A market with no imported rule for a substance is left out of that comparison rather than treated as permitting it.
Permitted here under conditions and prohibited, or more tightly held, elsewhere — so a formula built for this market may not travel.
