The Legal Status of Cannabis in Ontario

Ontario allows adults aged 19 and older to buy and possess non-medical cannabis. Legal access comes through the Ontario Cannabis Store and authorized private retailers. Rules for public possession, growing, smoking, driving and workplace use remain separate, so a legal purchase does not establish permission for every activity.

Age and Possession Limits

The public possession limit is 30 grams of dried cannabis or its equivalent in other products. This is not a general 30-gram cap on cannabis stored at home. Keep products secure and inaccessible to children, and use the dried-cannabis equivalent on the label when combining different product types.

Ontario’s cannabis-law overview confirms the age requirement and public limit. A product’s THC dose and its equivalent weight for possession are different measurements.

Retail Stores, Online Orders and Delivery

The Ontario Cannabis Store (OCS) sells online and supplies the regulated private retail market. Authorized stores can also sell to consumers, including through permitted pickup and delivery arrangements. The province’s purchasing guide explains the legal channels.

Buying from an unauthorized website is not made lawful by the fact that it ships from within Canada. Check that the business is an authorized retailer and that the order follows its approved delivery process.

Under the current retail regulation, private-store deliveries must be made by the authorization holder or its employee, with cannabis in its original unopened packaging, to the person at the ordered address in a permitted residence or private place. Delivery generally runs between 9 a.m. and 11 p.m. while the store is open, with a specified exception for landlord-imposed closures. These are distinct from the hours permitted for in-store or adjacent pickup.

Where Smoking and Vaping Are Permitted

Ontario does not impose a blanket ban on smoking cannabis on every sidewalk or in every park. Many outdoor public places are permitted under provincial rules, but municipal bylaws and property policies can be stricter. Confirm the rules for the actual location.

The Smoke-Free Ontario restrictions prohibit smoking and vaping in enclosed workplaces and public places, as well as designated outdoor settings. These include school grounds, playgrounds and nearby public areas; publicly owned sports areas and their surrounding buffer zones; restaurant and bar patios and the public area within nine metres; and hospital grounds.

Indoor common areas in apartment and condominium buildings are also restricted. A rental home’s lease, condominium rules or hotel policy may impose additional limits. Home childcare premises must remain smoke-free and vape-free even when children are absent.

Growing Cannabis at Home

Adults may grow up to four plants per residence for personal use, subject to tenancy and condominium restrictions. The allowance is shared by the household, not multiplied by the number of adults. Use legal starting material from OCS or an authorized retailer.

Do not describe Ontario’s ordinary growing rule as an indoor-only requirement. Check the property rules before choosing a location, and address access by children, electrical safety and moisture. The Cannabis Control Act also restricts cultivation in homes where childcare is provided, subject to its stated exception.

Driving Rules and the 2026 Changes

Impaired driving is illegal for all drivers. Additional zero-tolerance cannabis rules apply to drivers aged 21 and under, holders of G1, G2, M1 or M2 licences, and specified commercial drivers. Ontario’s cannabis-and-driving guidance identifies a medical-user exception to the zero-tolerance drug requirements; it does not permit driving while impaired.

Some penalties changed on July 1, 2026. The province’s current impaired-driving guidance lists seven-, 14- and 30-day immediate suspensions for successive young- and novice-driver violations, alongside education or treatment requirements and financial consequences. Criminal convictions carry additional penalties. Consult the current schedule rather than relying on older summaries of three-, seven- and 30-day suspensions.

Do not consume cannabis in a vehicle or boat that is being operated or could be put into motion. There are limited exceptions for certain medical passengers consuming without smoking or vaping, and qualifying vehicles or boats used as residences. An ordinary parked car is not a general consumption space.

Workplace and Medical Use

Non-medical cannabis consumption in an enclosed workplace remains prohibited. Employers must address hazards, and workers must perform their duties safely. A medical authorization does not remove workplace safety requirements or the restrictions on where smoking and vaping are allowed.

For residents and visitors, the practical checks are the same: use an authorized seller, stay within the public possession limit, confirm the property’s consumption rules, and arrange transport before using cannabis.
