To be legally sold in Canada, all natural health products (NHP) must have a product licence, and the Canadian sites that manufacture, package, label and import these products must have site licences.

To get product and site licences, specific labelling and packaging requirements must be met, good manufacturing practices must be followed, and proper safety and efficacy evidence must be provided.

All natural health products must have a product licence before they can be sold in Canada. To get a licence, applicants must give detailed information about the product to Health Canada, including: medicinal ingredients, source, dose, potency, non-medicinal ingredients and recommended use(s).

Once Health Canada has assessed a product and decided it is safe, effective and of high quality, it issues a product licence along with an eight-digit Natural Product Number (NPN) which must appear on the label. This number lets you know that the product has been reviewed and approved by Health Canada.
