Thinking about growing your own cannabis for medical purposes in Canada? You’re not alone. Many patients find that cultivating their own plants offers more control over their supply and strains, helping them better manage their symptoms. However, there are important rules and regulations you must follow to ensure you stay compliant with Canadian law.

In this guide, we'll break down what you need to know before you start growing marijuana at home.

Medical Cannabis and the Law in Canada

In Canada, growing cannabis for personal medical use is legal — but only if you have the proper authorization through Health Canada. The Access to Cannabis for Medical Purposes Regulations (ACMPR), now integrated into the Cannabis Regulations under the Cannabis Act, outlines the framework for home cultivation.

To legally grow cannabis for your own medical use, you must:

• Be a registered medical cannabis patient with a prescription from an authorized healthcare practitioner.
• Apply for a Health Canada production licence to either grow your own cannabis or designate someone to grow it for you.

How to Get a Licence to Grow Cannabis for Medical Use

Here’s a simple overview of the steps:

1. Consult with a Medical Cannabis Clinic
   Speak with a healthcare practitioner to assess whether medical cannabis is appropriate for your condition. GrowLegally’s experienced team can help you through a personal grow licence consultation.
2. Obtain a Cannabis Prescription
   If approved, you’ll receive a medical document (prescription) outlining your daily gram limit.
3. Apply to Health Canada
   Complete the necessary forms to register for a licence to grow for personal medical use or designate someone to grow it for you. You will need to submit:
   • A copy of your medical document
   • Proof of identity
   • Proof of your residence and the proposed grow site

4. Wait for Approval
   Health Canada will process your application and send you a registration certificate if approved.

Important Rules for Home Cultivation

Once approved, you must follow specific guidelines:

• Grow only the amount authorized under your licence (calculated based on your daily prescribed amount).
• Secure your plants properly, whether indoors or outdoors.
• Do not sell or share your cannabis. It’s strictly for your own medical use.
• Comply with local bylaws. Some municipalities may have additional rules regarding cannabis cultivation on private property.

Failure to comply can lead to fines, revocation of your licence, or even criminal charges.

Growing Without a Licence Is Illegal

It’s important to remember: without the proper authorization, growing cannabis — even for medical use — is illegal in Canada. Recreational users are allowed to grow up to four plants per household (not per person) under the Cannabis Act, but this is entirely separate from medical cannabis rules, which allow for much higher plant counts if authorized.

If you require higher amounts for medical treatment, you must go through the medical cannabis system.
