Canada Fragrance Allergen Labeling 2026: Requirements, Deadlines & Compliance Guide
Last updated: March 2026
If you manufacture, import, or sell cosmetics in Canada, a significant labeling deadline is fast approaching. Starting April 12, 2026, Health Canada requires cosmetic brands to disclose specific fragrance allergens directly on product labels — a major shift from the previous practice of listing them collectively under “fragrance” or “parfum.”
This guide covers everything you need to know: which allergens must be disclosed, the concentration thresholds that trigger disclosure, the phased timeline through 2028, what needs to change on your labels and CNF filings, and how Cosmereg can help you meet the deadline with confidence.
Why Health Canada Is Requiring Fragrance Allergen Disclosure
Fragrance ingredients are among the most common causes of allergic contact dermatitis from cosmetic products. For years, Canadian cosmetic regulations allowed brands to list all fragrance components under the single term “fragrance” or “parfum,” making it impossible for sensitized consumers to identify and avoid specific ingredients that trigger their reactions.
Health Canada’s regulatory amendments — published in the Canada Gazette, Part II, in April 2024 and coming into force in 2026 — change that. The new requirements bring Canada into close alignment with the European Union’s Cosmetic Products Regulation, which has required disclosure of 26 fragrance allergens since 2005 and expanded that list significantly in recent years. By mirroring the EU’s approach, Canada also commits to automatically adopting future EU updates to the allergen list, ensuring ongoing regulatory harmonization.
The Three Key Deadlines You Need to Know
April 12, 2026 — 24 Allergens for All Cosmetics
The first phase requires disclosure of 24 specific fragrance allergens on all cosmetic product labels when present above the threshold concentrations. This applies to both new products launching after this date and existing products already on shelves.
Threshold concentrations that trigger mandatory disclosure:
- Rinse-off products (shampoos, body wash, conditioners, face wash): ≥ 0.01%
- Leave-on products (moisturizers, serums, perfumes, deodorants): ≥ 0.001%
August 1, 2026 — 81 Allergens for New Products
For cosmetics newly introduced to the Canadian market from August 1, 2026 onward, the disclosure requirement expands significantly to 81 fragrance allergens — the full expanded EU list. The same concentration thresholds apply (0.01% rinse-off / 0.001% leave-on).
August 1, 2028 — 81 Allergens for All Existing Products
Products that were already on the market before August 1, 2026 are given additional time to transition. By August 1, 2028, all cosmetics sold in Canada must disclose the full list of 81 allergens where applicable.
The 24 Fragrance Allergens Required from April 12, 2026
The following 24 substances must be individually listed on cosmetic labels when present above the threshold concentrations. Use the INCI names exactly as listed when they appear in your ingredient list:
- Amyl cinnamal
- Amylcinnamyl alcohol
- Anisyl alcohol
- Benzyl alcohol
- Benzyl benzoate
- Benzyl cinnamate
- Benzyl salicylate
- Cinnamal
- Cinnamyl alcohol
- Citral
- Citronellol
- Coumarin
- d-Limonene
- Eugenol
- Farnesol
- Geraniol
- Hexyl cinnamaldehyde
- Hydroxycitronellal
- Hydroxymethylpentyl-cyclohexenecarboxaldehyde (also known as Lyral)
- Isoeugenol
- Lilial (Butylphenyl methylpropional)
- Linalool
- Methyl heptine carbonate
- 3-Methyl-4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one (also known as Methyl ionone)
These ingredients must appear in your ingredient list under their standard INCI name, in the correct position based on their concentration relative to other ingredients.
What Changes on Your Labels
Before April 12, 2026 (Current Practice)
Most brands currently list fragrance components collectively:
Ingredients: Water, Glycerin, ..., Fragrance (Parfum), ...After April 12, 2026 (Required)
If your fragrance blend contains, for example, Linalool above 0.001% in a leave-on product, it must be individually listed:
Ingredients: Water, Glycerin, ..., Fragrance (Parfum), Linalool, Citronellol, ...The qualifying allergens are listed after “Fragrance (Parfum)” in descending order of concentration alongside the other ingredients in the full list.
Bilingual Labeling Note
Canada’s bilingual labeling requirements still apply. Where the INCI name does not differ between English and French, one listing is sufficient. Where Health Canada guidance specifies French equivalents, both must appear. Check your Responsible Person or Health Canada’s labeling guide for the current bilingual requirements.
What Changes on Your CNF Filing
The Cosmetic Notification Form (CNF) — which must be filed with Health Canada within 10 days of the first sale of any cosmetic in Canada — must also reflect the new fragrance allergen disclosures.
From April 12, 2026, if any of the 24 qualifying fragrance allergens are present in your formulation above the thresholds, they must be individually disclosed in the CNF ingredient list — you can no longer list them collectively under “fragrance” in the notification.
This means brands must:
- Review every active CNF to identify products containing the 24 allergens
- Update the CNF ingredient declarations accordingly
- Re-file notifications where necessary before or by April 12, 2026
If you are using Cosmereg’s CNF filing service, we will handle this review and update process for your entire product portfolio.
How to Audit Your Product Portfolio
Follow these steps before the April 12, 2026 deadline:
Step 1: Request Full Fragrance Ingredient Disclosure From Your Supplier
Many fragrance suppliers provide compositions under confidentiality. Request a statement confirming whether any of the 24 listed allergens are present above the relevant thresholds (0.01% in rinse-off, 0.001% in leave-on). You do not need the full proprietary formula — just confirmation of which regulated allergens are present and at what approximate levels.
Step 2: Cross-Reference Against the 24-Allergen List
Compare your supplier’s disclosure against the 24 allergens listed above. Flag every product where one or more allergens exceed the thresholds.
Step 3: Update Label Artwork
For flagged products, update your ingredient list to individually name the applicable allergens after “Fragrance (Parfum).” Reprint labels or schedule reprinting ahead of the April 12 date.
Step 4: Update Your CNF Filings
For every flagged product with an active Canadian CNF, update the ingredient declaration to list the allergens individually. File amended notifications with Health Canada.
Step 5: Plan for the August 2026 Expansion (New Products)
If you are planning any new product launches in Canada after August 1, 2026, ensure those formulations are assessed against all 81 EU allergens from the outset.
Health Canada’s Compliance Promotion Period
Health Canada has announced that from April 12, 2026 to April 11, 2027, the agency will focus on compliance promotion rather than immediate enforcement. This means Health Canada’s priority during the first year will be education, guidance, and helping industry understand and implement the new requirements.
However, this does not mean brands can ignore the deadline. Health Canada has stated it will still respond using its usual risk-based process if it receives health or safety-related incidents or complaints related to unlabeled allergens. Non-compliance also exposes your brand to product recalls and reputational risk if a consumer has an adverse reaction to an undisclosed allergen.
The safest approach is to be fully compliant by April 12, 2026.
Comparing Canada’s Requirements With the EU
Canada’s new fragrance allergen rules are deliberately aligned with the EU Cosmetic Products Regulation. Here’s how the two frameworks compare:
| Canada (from April 2026) | EU (current) | |
|---|---|---|
| Phase 1 allergens | 24 | 26 (since 2005) |
| Full allergen list | 81 (from Aug 2026 for new products) | 56+ (expanded in 2023) |
| Rinse-off threshold | 0.01% | 0.01% |
| Leave-on threshold | 0.001% | 0.001% |
| CNF/notification disclosure | Required | Required |
| Automatic EU list updates | Yes (incorporated by reference) | Ongoing updates |
The key practical difference: Canada’s Phase 1 list of 24 is slightly smaller than the EU’s original list of 26 because two of the original EU substances (Oak moss extract and Tree moss extract) are handled under Canada’s Hotlist rather than as labeling disclosures.
Going forward, Canada will automatically adopt future EU updates to the allergen list, meaning brands that are already EU-compliant will have a strong foundation for Canadian compliance as well.
Penalties and Consequences for Non-Compliance
Failure to disclose fragrance allergens as required by Health Canada can result in:
- Mandatory product recalls ordered by Health Canada
- Stop-sale orders preventing further distribution
- Fines under the Food and Drugs Act
- Damage to your brand’s reputation, particularly if a consumer files a complaint or suffers an adverse reaction from an undisclosed allergen
- Delisting from Canadian retailers who conduct their own compliance audits
For brands selling on platforms like Amazon Canada, non-compliance with labeling regulations has already resulted in product delisting — a trend that is likely to intensify as the April 2026 deadline approaches.

Frequently Asked Questions
Q: Does the April 2026 requirement apply to products already on the market?
A: Yes. The requirement to disclose the 24 allergens from April 12, 2026 applies to all cosmetics sold in Canada, including existing products. However, the expansion to 81 allergens starting August 1, 2026 only applies to new products until August 1, 2028, when all products must comply.
Q: What if an allergen is present below the threshold — does it still need to be listed?
A: No. Disclosure is only required when a fragrance allergen is present at or above 0.01% in rinse-off products or 0.001% in leave-on products. If below the threshold, no individual listing is required.
Q: Do I need to update my CNF as well as my label?
A: Yes. Both the product label and the CNF filing must individually list the qualifying fragrance allergens. You cannot list them collectively under “fragrance” in either document after April 12, 2026.
Q: My fragrance supplier won’t disclose the full formula. What do I do?
A: You don’t need the full proprietary formula. Request a fragrance allergen declaration — a statement confirming which of the regulated allergens are present and whether they exceed the applicable thresholds. Reputable fragrance suppliers routinely provide these.
Q: We sell the same product in the EU with allergens already disclosed. Are we automatically compliant in Canada?
A: Largely yes, if your EU label already discloses the same allergens using the same INCI names. However, Canada requires bilingual labels and your CNF must also reflect the allergen disclosures. Check with a Canada-specific compliance expert to confirm.
Q: Will Health Canada take enforcement action immediately after April 12, 2026?
A: Health Canada has announced a one-year compliance promotion period (April 12, 2026 – April 11, 2027) focused on education rather than enforcement. However, if Health Canada receives complaints or safety incidents involving undisclosed allergens, it will respond using its standard risk-based process. Full compliance by the deadline remains strongly advised.
