There is no medical cannabis card in Canada: legal access to cannabis for medical purposes starts with a medical document from a doctor or nurse practitioner, which you then use to register with a seller licensed by Health Canada, or to register with Health Canada to grow your own.
So what does that document say, how long is it valid and what does a medical registration unlock beyond a retail store?
In this guide, you'll discover:
- the three steps from first consultation to first medical order;
- what a valid medical document must show under the Cannabis Regulations;
- the medical possession limit and how to prove it in public;
- what medical cannabis costs, and where the tax credit and Veterans Affairs coverage fit in.
This guide is general information, not medical or legal advice. Talk to a health care practitioner about your own situation.
Is there a medical cannabis card in Canada?
In Canada, legal access runs on paperwork: under the Cannabis Act and Part 14 of the Cannabis Regulations, a health care practitioner provides a medical document that supports your use of cannabis for medical purposes, and a licensed seller registers you as a client on the basis of that document. Your registration document is the proof you carry.
So med cards, MMJ cards, medical marijuana cards and medical weed cards all mean the same thing: the medical document. Some patients call it a cannabis prescription, although it goes to a licensed seller rather than a pharmacy. If a licensed producer (LP) ships a client card with your order, treat it as a bonus; your registration is the legal proof. Wondering whether a doctor would consider it for your condition? Our post on whether weed is prescribed for anxiety covers that consultation.
Getting a medical document in 3 steps
Three steps take you from first appointment to your first order of medical cannabis, in this order.
Step 1: see a health care practitioner
Book a consultation with a doctor or nurse practitioner authorized to practise in their province. Virtual appointments through medical cannabis clinics are common, and some patients ask their family doctor or usual health care provider instead. Note your condition, symptoms, what you've tried and every medication you take. Under Health Canada's wording, the practitioner may provide a medical document if they determine a limited amount of cannabis is required.
Step 2: get your medical document signed
If the practitioner agrees, they sign and date the medical document. It sets your daily quantity of dried cannabis in grams and a period of use, capped at one year. Some practitioners also discuss format and dose with you: dried flower to vaporize, oils, capsules or edibles. Our guide to what type of weed consumers choose for anxiety is a good primer before that appointment.
Step 3: register with a licensed seller
Pick a licensed seller authorized by Health Canada for medical sales (Health Canada's pages also call them licensed producers), complete its registration form and send the original medical document. If the patient is a child or someone who needs help, a responsible adult over 18 can be named on the registration. Once registered, you order dried or fresh cannabis, oils, edibles, topicals or extracts directly from the licensed seller, and it ships to the address on your registration.
What goes on a medical document
Under section 273 of the Cannabis Regulations, a valid medical document shows:
- the practitioner's name, profession, business address and phone number;
- the province where they're authorized to practise, and the number that province assigned to their authorization;
- your name and date of birth;
- the address where the consultation took place;
- your daily quantity of dried cannabis, in grams;
- a period of use in days, weeks or months, up to one year.
The practitioner signs and dates it, confirming the information is correct and complete. When the period of use expires, you need a new medical document and a renewed registration with your seller, so book the renewal appointment a few weeks early and keep your supply steady.
Growing cannabis for medical purposes yourself
The second legal route, often called a grow licence, skips the licensed seller. You mail Health Canada's Access to Cannabis for Medical Purposes Program the original medical document with a registration application. To qualify, you must ordinarily live in Canada, be 18 or older and attest that you haven't been convicted of a cannabis-related offence in the past 10 years. Health Canada then issues a registration certificate stating your daily quantity and the number of plants you may grow, which its online plant calculator lets you estimate.
You can also name a designated person to grow for you. A designated person can produce for at most two registered people, which can include themselves. Registered growers can also register with a licensed seller to buy starting material such as seeds or plants.
Medical cannabis possession limits
With a medical document and a registration, you can possess the lower of a 30-day supply or 150 grams of dried cannabis, or the equivalent in cannabis oil, edibles or other products. In practice that's 30 times your daily quantity: at 2 grams a day, the limit is 60 grams; at 5 grams a day or more, the 150-gram ceiling applies. Health Canada describes that medical amount as coming on top of the 30 grams allowed for non-medical purposes.
Carry your registration document with your supply. Health Canada says patients should be prepared to show law enforcement that they're legally allowed to carry more than 30 grams in public.
What medical cannabis costs, and who pays
Licensed sellers set their own prices, so the cost of medical cannabis depends on the licensed producer, the strains and the format you order. Before you register, ask about prices, shipping fees and whether the seller offers a compassionate pricing or discount program for patients on a limited income.
The medical expense tax credit (CRA)
Medical cannabis ordered from a licensed seller counts as an eligible medical expense on your tax return when you hold a medical document and are registered with that seller, according to the Canada Revenue Agency. For the 2025 tax year, the medical expense tax credit applies to eligible expenses above the lesser of $2,834 or 3% of your net income. Keep every receipt and ask an accountant how it fits your return.
Veterans Affairs Canada coverage
Veterans Affairs Canada reimburses eligible veterans for cannabis for medical purposes ordered from a federally licensed seller, up to 3 grams a day of dried cannabis or the equivalent. Eligibility is tied to a Disability Pension, Disability Award or Pain and Suffering Compensation. For products ordered on or after April 1, 2026, the maximum reimbursement rate is $6.00 per gram, down from $8.50.
Private insurance and provincial health plans
Private insurance plans each set their own rules on medical cannabis, so call your insurer before you order and ask whether a claim needs a copy of the medical document, your registration or your receipts. We cover medical cannabis and private insurance in Canada and whether OHIP, Ontario's provincial health plan, covers medical marijuana in separate posts.
Medical cannabis or recreational: which route fits?
Provincial and territorial authorized stores and websites serve recreational buyers, and Health Canada confirms that patients authorized by a practitioner can buy there too. The medical route adds what a store counter skips: a practitioner who sets your daily quantity and reviews your treatment at renewal, the higher possession limit, the tax credit, Veterans Affairs reimbursement and delivery to your door.
Working through format and dose questions? Our guides on how to take cannabis oil and cannabis strains for pain and inflammation explain what consumers report with each format and cannabinoid profile, THC or CBD. Raise dose, side effects and medication interactions with your practitioner too.

Can I get a medical cannabis card online in Canada?
Yes, in the way that matters. The consultation with a doctor or nurse practitioner can happen online, and the signed medical document then goes to the licensed seller you choose. You then fill in that seller's registration form. What you end up with is a registration as a medical cannabis patient, which is your legal proof of access, rather than a government-issued card.
How long is a medical document valid in Canada?
A medical document stays valid for the period of use your health care practitioner writes on it, up to one year under section 273 of the Cannabis Regulations. Your doctor can set a shorter period, for instance to review your dose after a few months. When it expires, you renew with a new medical document and update your registration with your licensed seller before you order again.
Can a nurse practitioner sign a medical cannabis document?
Yes. The Cannabis Regulations define a health care practitioner as a medical practitioner or a nurse practitioner, provided they are entitled to practise in a province and their authority to support cannabis use is unrestricted there. Their province and the authorization number assigned by that province must both appear on the medical document they sign.
Do I need a family doctor to get medical cannabis?
A family doctor is optional. Any doctor or nurse practitioner authorized in their province can assess you and provide a medical document, including one you see through a medical cannabis clinic or a seller's virtual consultation. Still, tell your family doctor: they know your conditions and the other medications you take.
Does my medical document work in every province?
Yes. The Cannabis Act and the Cannabis Regulations are federal, so your medical document and your registration with a licensed seller apply in every province and territory. Provincial and municipal rules on where you can consume cannabis still apply, so check them. Your possession limit, 30 times your daily quantity up to 150 grams, stays the same across provinces.
Does Veterans Affairs Canada cover medical cannabis?
For eligible veterans, yes. VAC reimburses cannabis for medical purposes ordered from a federally licensed seller, up to 3 grams a day, for veterans receiving a Disability Pension, Disability Award or Pain and Suffering Compensation. For orders placed on or after April 1, 2026, the maximum rate is $6.00 per gram. Amounts above 3 grams a day are exceptions, usually requiring a medical specialist's support.
Can I buy medical cannabis from two sellers at once?
Only one at a time per medical document. Section 276 of the Cannabis Regulations prohibits obtaining cannabis from more than one source at a time on the basis of one document. You can switch licensed sellers whenever you like: tell your current licensed seller, and once the new one accepts your registration, the old one must transfer your medical document on request. A new medical document from your doctor also works.
Is medical cannabis tax deductible in Canada?
Medical cannabis counts toward the medical expense tax credit on your tax return, which works as a credit rather than a deduction. Orders from the licensed seller you're registered with qualify when you hold a medical document. For 2025, the credit covers eligible expenses above the lesser of $2,834 or 3% of your net income. Keep your receipts and ask an accountant.
