Overview

The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) licenses Ontario dairy plants under:

You need a dairy plant licence if you:

  • process raw cow or goat milk
  • process pasteurized cow or goat milk into milk products that you sell for resale (wholesale distribute)
  • transform a finished cow and/or goat milk product into another milk product which you sell for resale (wholesale distribute), such as repackaging a bulk product into smaller-sized units

Dairy plant licensing is not based on the size of processing plant, volume of milk or milk products processed, or amount of finished product made.

Exemptions

A provincial licence is not required for businesses that:

If you plan to operate a food premise, you must notify your local public health unit and comply with the requirements of the Health Protection and Promotion Act (Ontario) and O. Reg. 493/17: Food Premises.

For sheep or water buffalo milk, consider a co-packing arrangement where the milk is processed in a dairy plant that is licensed under the Milk Act.

How to apply

Follow these steps to apply:

  1. Gather the required documents.
    1. If you’re purchasing raw cow milk, you need a letter from Dairy Farmers of Ontario (DFO) as proof that you have secured a supply of milk.
    2. If you’re constructing or altering a building for use as a dairy plant, you need to apply for a construction permit along with your licence application. You need to provide detailed drawings and specifications of your proposed construction or alteration, including equipment layout and specifications. Download a copy of the permit application for more details.
    3. If you plan to process dairy products on your farm, contact us at dairyfoodsafety@ontario.ca or 1-877-424-1300 for a copy of the Guidelines for On-Farm Dairy Processing Plants.
  2. Fill out and submit the necessary forms and attachments for:
    1. An application for a new licence for the operation of a dairy plant
    2. If applicable, an application for a permit to construct or alter a building intended for use as a dairy plant (for new applicants)
  3. Once we receive your completed application(s), we will provide you with next steps.

When to begin construction

You can only begin construction after the director appointed under the Milk Act has approved the permit application. We can help you with information about applicable regulatory requirements throughout your planning and construction phases.

When to begin operation

You can only begin operation after you have received a licence issued by the director. The director will issue a licence after:

  • the plant is complete and ready to operate
  • we have inspected and confirmed that the plant meets all applicable regulatory requirements under the Milk Act as provided on the pre-licensing assessment checklist

Federal licensing

Only facilities that are federally licensed can export milk and milk products to other provinces and countries.

If you plan to sell or distribute milk products outside of Ontario, you need both:
