If you’re using cannabis for medical reasons in Canada, you’ve likely asked yourself: “How much am I actually allowed to carry or store legally?” At GrowLegally, we speak with patients every day who are unsure about the rules—especially when it comes to possession limits, storing cannabis at home, and travelling across provinces. With laws constantly evolving, it’s important to understand your rights so you can feel confident, protected, and supported on your health journey.

In Canada, cannabis is legal for both recreational and medical use. Under the Cannabis Act, any adult (18 or 19+, depending on your province) can legally carry up to 30 grams of dried cannabis—or its equivalent in oils, edibles, or concentrates—in public. This limit applies whether you’re walking down the street in Toronto or flying across the country. It's the same for recreational consumers and medical patients.

But medical patients benefit from extended allowances. If you're registered with Health Canada or have a valid medical document, you can carry up to 150 grams of dried cannabis or a 30-day supply—whichever is less—plus the additional 30 grams permitted under recreational law. That means medical cannabis users can legally travel within Canada with up to 180 grams in total, provided they carry proper documentation.

When it comes to storing cannabis at home, the rules are much more flexible. There is no limit on how much cannabis you can keep in your residence, whether for medical or recreational use. Patients with authorization to grow their own medicine under the ACMPR (Access to Cannabis for Medical Purposes Regulations) can store their entire harvest without restriction, giving them reliable access throughout the year.

While these allowances give patients more control over their care, they also come with responsibilities. In Ontario and across Canada, cannabis should always be stored securely, away from children and pets, and must not be used in vehicles or areas where smoking is prohibited. If you're travelling domestically, it’s wise to keep your cannabis in its original packaging and carry proof of your authorization.

International travel is a different story. It is illegal to cross the Canadian border with cannabis—even with a medical prescription—unless you have government-issued exemptions from both Health Canada and the country you’re visiting. Even travelling to a destination where cannabis is legal, such as Jamaica or certain U.S. states, requires special documentation. Without that, transporting cannabis across borders is considered a criminal offence. If you’re planning to travel outside Canada and rely on medical cannabis, GrowLegally can help guide you through the exemption process to ensure compliance and peace of mind.

At GrowLegally, we support patients in Toronto, across Ontario, and throughout every Canadian province. Whether you need help getting your prescription, renewing your medical cannabis licence, or applying for a personal grow permit, we’re here to make it simple and stress-free.

If you're ready to take the next step or need clarity on what you can legally carry, store, or travel with, we're here for you.
