Canada treats supplements as Natural Health Products (NHPs) — a distinct regulatory category sitting between food and pharmaceuticals. Every supplement sold in Canada requires a Natural Product Number (NPN) or Exemption Number (EN) before it can be legally marketed. Here's how the process works.
NHPs include vitamins, minerals, herbal remedies, homeopathic medicines, traditional medicines, probiotics, and amino acid supplements. Sports nutrition products, protein powders, and most wellness supplements fall under NHP regulations. Some products may be regulated as foods or drugs depending on their claims and formulation.
To sell an NHP in Canada you must apply to Health Canada's Natural and Non-Prescription Health Products Directorate (NNHPD). The application requires: product name and dosage form, a complete ingredient list with sources and quantities, evidence of safety and efficacy for each health claim, proposed label text, and quality manufacturing evidence (GMP certificate).
Processing times vary by product class: Class I (lowest risk, pre-cleared monograph) takes 10 days; Class II takes 60 days; Class III (novel claims, new ingredients) takes 300 days. Plan 6–12 months for most products.
NHP labels must include: the product name, NPN or EN number, dosage form, recommended use or purpose, recommended dose and duration, risk information (cautions, warnings, contra-indications, known adverse reactions), medicinal ingredients with their quantities per dose, non-medicinal ingredients, lot number, and expiry date.
Bilingual labelling (English and French) is mandatory for all products sold nationally. French-language requirements are stricter in Quebec.
All NHPs must be manufactured, packaged, labelled, and stored in compliance with Health Canada's NHP GMP regulations. Foreign manufacturers must hold an equivalent GMP certification recognised by Health Canada (NSF, USP, or third-party audited). Your site licence application must reference your manufacturer's GMP status.
Commercial NHP imports require a valid Site Licence for the importer and an NPN for each product. Products arriving without an NPN can be detained at the border. CBSA (Canada Border Services Agency) enforces this at ports of entry. Ensure your customs broker is familiar with NHP import documentation.
Budget 6–12 months from application to NPN issuance for standard products. Application fees are nominal (under $500 CAD) but the cost of assembling the dossier — particularly evidence packages for novel claims — can run $5,000–$25,000+ depending on complexity. Amazon Canada and major retailers (Shoppers Drug Mart, Walmart Canada, Costco Canada) all require a valid NPN before listing.
