There are a lot of things that you should learn about medical marijuana before you try to get some for yourself. Learning more about medical cannabis helps you understand the steps needed to legally access it in Ontario and across Canada. While recreational cannabis dominates headlines, the medical program remains a vital pathway for patients who need safe, consistent, and legally protected treatment.

Ontario is the largest cannabis market in Canada. In 2024, licensed cannabis stores sold over 409 million grams, worth more than $2.15 billion. The Ontario Cannabis Store (OCS) reported profits of more than $234 million, with over 1,700 cannabis stores now operating across the province. Recreational access is everywhere, but medical cannabis offers patients unique advantages: tax deductibility, the option for higher prescription amounts, and eligibility for a personal cannabis grow licence.

Health Canada data shows that by late 2024 there were over 160,000 active medical cannabis registrations with licensed sellers, plus nearly 16,000 individuals approved for personal or designated production. In Ontario, patients may legally cultivate dozens of cannabis plants depending on their authorization, compared to only four allowed recreationally. This is especially important for those with chronic pain, cancer, epilepsy, or arthritis. Veterans managing PTSD also benefit, and programs for medical cannabis for veterans continue to provide much-needed support.

While the legal system has expanded, illicit cannabis remains, often undercutting licensed prices. Still, legal medical access ensures patients receive safe, regulated, and reliable medicine.

Health Canada confirms there are no restrictions on the conditions for which medical cannabis can be authorized, making the system more inclusive than ever. Whether you are wondering how to get medical marijuana in Canada, how to apply for a medical marijuana card in Ontario, or whether growing your own plants makes sense, patient educators and doctors can help guide the way.
