Veterinary Drug Identification Number (DIN) submissions are covered by Part C - Division 1 of the Food and Drug Regulations for drugs that are not considered “new drugs” (hereafter called “Division 1 drugs”). This page does not cover new drugs or generic drugs for veterinary use.

Who can apply

This page provides information to assist veterinary drug manufacturers (sponsors) in preparing a well-structured DIN submission to facilitate screening and review by Health Canada’s Veterinary Drugs Directorate.

Drug sponsors must follow Part C - Division 2 and obtain a drug establishment licence (DEL) as per Part C - Division 1A.

If you’re filing a Veterinary DIN submission for an Antiseptic Teat Solution, consult the Antiseptic Teat Solutions Monograph. It outlines the conditions of use and labelling permissible under the Division 1 Regulations.

Before you apply

This section includes important information to help sponsors assess whether their product is eligible for review as a Division 1 drug.

A Division 1 drug must be comparable to one or more drug products previously approved under Division 1 in all of these areas:

To search for Division 1 products that are comparable in these 4 areas, refer to the Drug Product Database for information on drugs authorized for sale by Health Canada.

Products approved under Division 8, considered “new drugs”, cannot be used as comparable products for review of a Division 1 drug. Information about "new drugs" is available in the Notice of Compliance database.

If you’re unsure whether your product is considered a Division 1 drug, refer to Classification of products for use in animals for steps to confirm a classification.

Non-medicinal ingredients

The non-medicinal ingredients (also called ‘inactive ingredients’ or ‘excipients’) don’t need to be comparable to other Division 1 drugs. However, we will evaluate them during review to ensure they:

After you apply

Our Veterinary drugs - Management of regulatory submissions guidance provides more details about how we manage submissions, such as:

During the review

We’ll assess the information you provide us and may request more to help us make a decision. Response times depend on the complexity of the submitted information. If your product is considered to have a New Drug status, we will inform you and provide an opportunity to justify or revise your product. We may request information in support of safety, efficacy and quality in certain cases.

During review, we assess if the labelling uses the proper and most up to date wording of the conditions of use and warnings. This includes the withdrawal period if the drug is for food-producing animals.

We’ll use the veterinary Prescription Drug List and Controlled Drugs and Substances Act during the review to assign one or more schedules to your product based on the active ingredient(s) and determine if the product requires a prescription.

If the submission is considered to be acceptable, your product will receive a DIN. It will not receive a Notice of Compliance (NOC).

Filing updated information after you have a DIN

If you want to make any changes after we issue your DIN, you can file through one of these pathways:

  1. Administrative DIN
    For changes to a drug product that do not need scientific assessment, such as changes in brand or manufacturer name. File your submission with the Administrative Changes - Certification Form For Veterinary Drugs, along with the items listed below.
  2. Change to DIN
    For any other change to the product or labelling, file a Change to DIN. We may need additional justification to adequately assess the acceptability of the change. During review, we may propose the filing of a New Drug Submission if the change falls within the definition of New Drug as stated in Division 8 of the Regulations.

As part of the submission, the sponsor must submit:

If the manufacturer has changed after a corporate merger, buy-out or licensing agreement, provide a letter from the initial sponsor that authorizes the:
