The Natural Health Product Site Licensing Bulletin

The Natural and Non-prescription Health Products Directorate (NNHPD) is the regulating authority for non-prescription drugs and natural health products (NHPs) in Canada. This web page is specific for NHP site licensing.

A site licence is required for the physical site in Canada where a business or individual manufactures, packages, labels or imports an NHP for sale. This requirement is set out in the Natural Health Products Regulations (Regulations). To obtain and keep a site licence, regulated parties must comply with good manufacturing practices (GMPs) for each site, as outlined in Part 3 of the Regulations.

To promote compliance with regulatory requirements, the NNHPD provides guidance on site licensing and GMPs for NHPs. Another way we do this is by sending out NHP Site Licensing Bulletins regularly to our stakeholders which announce site licensing changes or provide reminders of regulatory obligations.

The table below lists all of the NHP Site Licensing Bulletins that have been sent out to date. If a specific bulletin is not available for viewing, you can ask for a copy by emailing us at Be sure to give us the bulletin number, date and title of the one you would like to receive.

Check back often for new content. We will notify you by email when there is a new NHP SL Bulletin.
