Product information

From Health Canada

Note - The product information found within this database originates from organizations not subject to the Official Languages Act and is available in the language in which it was written and submitted to Health Canada.

Note - The market status of a product is now available in the LNHPD and identifies if a product is "marketed" or "not marketed" in Canada. Product licence holders may voluntarily provide the Natural and Non-Prescription Health Products Directorate (NNHPD) with information about whether their product is currently available to Canadian consumers. Where no information has been provided, the default status is "not marketed". The "current status" field remains unaffected and will continue to indicate the status of the product licence (i.e., active, discontinued, stop sale, cancelled, or suspended). Note that where a licence has been suspended, cancelled or under stop sale, the product cannot be legally sold in Canada.

Product licence holders - if you wish to update a product's market status, you are invited to complete the Natural Health Products Market Notification Web Form. As with all other notifications, there is no current service standard. The NNHPD will process the market status update as soon as feasible, based on its available resources. As a reminder, market notification is voluntary; therefore, a licence holder is not required to wait for the LNHPD to be updated before a licensed product is sold in Canada. As such, products that are identified in the LNHPD as "not marketed" may still be sold in Canada.
