Is Psilocybin Legal in Ontario?
In short: No — psilocybin is not legally permitted for recreational use in Ontario.
Psilocybin (the psychoactive compound in “magic mushrooms”) remains illegal under federal Canadian law — and because Ontario follows federal drug policy, recreational use, possession, sale, or distribution of psilocybin is prohibited in the province.
What the Law Says, Is Psilocybin Legal in Ontario?
Psilocybin is classified as a Schedule III controlled substance under Canada’s Controlled Drugs and Substances Act (CDSA).
This means it is illegal to possess, produce, or sell without federal authorization. Ontario does not have its own separate legalization for psilocybin.

Medical & Research Access in Ontario|Is Psilocybin Legal in Ontario?
Although recreational use is illegal, there are limited legal pathways for psilocybin in Ontario under federal exemptions:
1. Health Canada Exemptions (Section 56)
The federal government can grant individualized legal access to psilocybin for medical or compassionate reasons. Some Canadians — including residents of Ontario — have obtained permission to use psilocybin for:
- End-of-life distress
- Treatment-resistant mental health conditions
- Participation in approved research
2. Clinical Trials & Research
Ontario hosts research institutions that conduct federally authorized clinical studies involving psilocybin-assisted therapy. These trials are legal and regulated.
Enforcement in Ontario
Although possession and distribution are illegal, law enforcement in Ontario has at times taken a low-priority approach toward individual possession — similar to cannabis policy before legalization. However:
- This does not mean psilocybin is legal.
- Prosecutors can still pursue charges.
- Police may still conduct seizures and arrests.
For the most current enforcement trends, consult Ontario law enforcement or public health resources.
Comparing to Other Substances
Unlike cannabis — which is legal for recreational use in Canada and Ontario — psilocybin has not been legalized.
Ketamine, another psychoactive drug, is legal when prescribed by a healthcare provider, but that is separate from psilocybin’s status.
What You Can Do in Ontario
Even though psilocybin isn’t legal for everyday use:
- You can participate in federally authorized research if eligible.
- Healthcare providers can apply for access on behalf of patients through the Special Access Program.
- Advocates continue to push for expanded medical access.
