All products considered under this pilot must continue to follow existing requirements for VHPs. Claims on marketed VHPs are limited to general health claims and must not include anti-parasitic, antimicrobial replacement or therapeutic claims.

How to participate in the pilot project

Pre-screening process

To participate in the pilot, interested companies with eligible products should:

  1. Request a pre-screen template from Health Canada's VHP at
  2. Submit a completed template for each product to be considered to Health Canada's VHP email account between March 15, 2021 to April 2, 2021.

Because this is a pilot project, the number of products accepted will be limited. Companies may submit up to 2 products, on separate templates, for consideration. To allow for fair participation, 1 product per company will be considered before accepting a second product from a company.

Submissions will be considered on a "first come, first served" basis. As a result, companies are encouraged to submit fully completed pre-screen templates to HC as soon as possible.

Submission of a pre-screen template does not guarantee that the product will be "notified" or included in the pilot project.

HC and the CFIA will jointly review submissions to determine eligibility. Applicants will be informed of the outcome of the pre-screening process.

Notification process

HC will inform successful applicants of products that are eligible for the pilot.

Companies will be asked to complete and submit a notification form for the product via the VHP web application. Companies should only submit this notification once they have received confirmation from HC that the product is eligible for the pilot project.

Information on guidelines, processing and fees for VHPs is available on the page About the VHP notification program. Failure to provide all requested information may result in delays or rejection of the application.

Manufacturers of VHPs are required to follow Part 3 - Good Manufacturing Practices (GMPs) of the Natural Health Products Regulations. Although companies are not required to submit manufacturing information as part of the notification process, companies are responsible for having all of the data available should HC request it.

Applications that meet all the requirements after verification will be accepted for notification, listed in the public list of Notified Products on Health Canada's website and assigned a notification number.

Publication of compendium

The CFIA will prepare and publish on its website the VHP in feed compendium (Compendium) containing all products that have been successfully notified through this pilot project for use in feed.

Once products are listed in the Compendium, they may be used in the manufacture of livestock feeds. The Compendium will include information that is required on the label of livestock feeds that contain a VHP.

The publication of the Compendium is expected by July 2021.

Additional details

Under the VHP notification program, the principal contact for the notifier (such as the chief executive officer or a director of the company) will be required to attest that there is:

Because these VHPs are intended for use in feeds, it must be considered whether normal feed manufacturing practices such as pelleting or extrusion would affect the availability or stability of the active ingredients and efficacy of the VHP.

The recommended dose for the VHP should also indicate the types of feeds it is suitable for use in (for example, pellet, mash, etc.). If manufacturers indicate that their product is suitable for use in pelleted feeds, the notifier should be able to demonstrate this suitability if requested by HC.

Products that are already registered as feeds or have been previously notified as a VHP (for example, for use in drinking water) may be submitted for this pilot if they meet all the eligibility requirements. These products will need to be re-notified with the specific in-feed instructions and dosage form, as applicable.

The label of a livestock feed that includes a notified VHP will contain information from the Compendium, including the notification number of the VHP.

For the purposes of this pilot, feeds may only contain VHPs at the level and for the duration of use listed in the Compendium. Feeds may not contain mixtures of different VHPs, or a VHP and a conventional medicating ingredient (with a drug identification number), in the same feed.


The proposed timeline for this pilot is as follows:


If you have any questions, contact HC's Veterinary Drugs Directorate by email at with "VHP in feed pilot" in the subject line.
