Cannabis Laws in Toronto

The legal framework

Cannabis in Toronto is governed by three overlapping layers of law:

1. Federal: The Cannabis Act (S.C. 2018, c. 16) legalized recreational cannabis across Canada on October 17, 2018 ^[1]. It sets national rules for production, possession limits, impaired driving, and packaging.
2. Provincial: Ontario's Cannabis Control Act, 2017 and Cannabis Licence Act, 2018 govern retail sales, age limits, and where cannabis can be consumed ^[2]. The Smoke-Free Ontario Act, 2017 (SFOA) restricts where you can smoke or vape cannabis ^[3].
3. Municipal: The City of Toronto adds bylaws restricting cannabis smoking in city parks and on many public properties ^[4].

In practice, provincial and municipal rules are where most Torontonians actually interact with cannabis law. Strong evidence

Possession, purchase, and age

• Minimum age: 19 in Ontario (higher than the federal minimum of 18) ^[2].
• Public possession limit: Up to 30 grams of dried cannabis, or equivalent, per adult ^[1].
• Where to buy legally: Private brick-and-mortar stores authorized by the Alcohol and Gaming Commission of Ontario (AGCO), or online through the Ontario Cannabis Store (OCS.ca), which is the only legal online retailer in Ontario ^[5].
• Sharing: Adults can share up to 30 g with other adults. Giving or selling to anyone under 19 is a serious criminal offence ^[1].

Buying from unlicensed dealers or 'gray market' delivery services remains illegal, even though enforcement varies. Strong evidence

Where you can (and can't) consume

Ontario's rule of thumb: you can smoke or vape cannabis anywhere you can smoke tobacco, with several important exceptions ^[3].

Generally allowed:

• Private residences (subject to landlord/condo rules — see below)
• Many outdoor public places, including most sidewalks

Prohibited under the SFOA and related laws:

• Enclosed public places and workplaces
• Within 20 metres of schools, playgrounds, sports fields, and publicly-owned sports surfaces
• Restaurant and bar patios
• Motor vehicles and boats (whether moving or not, with narrow exceptions for boats with permanent sleeping quarters)
• Hospital and long-term care grounds

Toronto-specific: The City of Toronto prohibits cannabis smoking and vaping in city parks, on beaches, and in most public squares under municipal bylaw ^[4]. This is stricter than the provincial baseline. Fines start at $305 for a set-fine offence but can be higher on summons.

Edibles and other non-smoked forms are not restricted by the SFOA, but individual venues can ban them. Strong evidence

Rentals, condos, and landlord rules

Legalization did not give tenants a right to smoke cannabis in rental units. Landlords in Ontario can prohibit smoking (including cannabis smoking) in leases, and condo corporations can pass rules or amend declarations to ban smoking in units and on balconies ^[6].

Existing tenants with leases that predate a new no-smoking rule may have some grandfathered rights, but landlords can still act on smoke that disturbs other tenants under the Residential Tenancies Act. Growing plants at home is legal federally, but landlords can restrict or prohibit cultivation in the lease.

If you rent, check your lease before smoking or growing. Disputes go to the Landlord and Tenant Board. Strong evidence

Home cultivation

The Cannabis Act allows adults to grow up to 4 cannabis plants per residence (not per person) for personal use, from seeds or seedlings obtained from a legal source ^[1]. Ontario follows this federal limit.

Rules:

• Plants must be from legal seeds/seedlings (OCS or licensed retailers)
• 4-plant maximum applies to the dwelling, regardless of how many adults live there
• Selling what you grow is illegal without a licence
• Landlords and condo boards can prohibit growing

Quebec and Manitoba banned home growing entirely — Ontario did not. Strong evidence

Driving and cannabis

Impaired driving is where Toronto cannabis users most often get into serious trouble. Federal law sets per se THC blood limits ^[7]:

• 2 ng/mL to under 5 ng/mL THC: summary offence, up to $1,000 fine
• 5 ng/mL or more THC: hybrid offence, criminal record possible
• THC combined with alcohol (≥2.5 ng THC + ≥0.05 BAC): hybrid offence

Ontario adds administrative penalties: an immediate 3-day licence suspension and $250 penalty for a first occurrence of drug-impaired driving, escalating for repeat occurrences. Young, novice, and commercial drivers must have zero THC in their system ^[8].

Police can demand a roadside oral fluid test if they reasonably suspect drug use. Refusing is itself a criminal offence. There is no reliable science on exactly how long after use a person is impaired or above the legal limit — it varies dramatically by dose, product, and individual. Strong evidence The 'don't drive for X hours' rules of thumb circulating online are folklore, not established medicine. Disputed

Medical cannabis

Canada's separate medical cannabis system, run under the Cannabis Regulations, still exists alongside the recreational market ^[9]. Patients with authorization from a healthcare practitioner can:

• Register with a federally licensed seller and receive cannabis by mail
• Register with Health Canada to grow their own (or designate a grower) in amounts based on their prescribed daily dose — often well above the 4-plant recreational limit
• Possess up to 150 g of dried cannabis or a 30-day supply in public, whichever is less

Medical cannabis is not covered by OHIP, but some private insurance plans and veterans' benefits reimburse it. Strong evidence

Recent and pending changes

• October 2019: Ontario transitioned from a lottery-based licensing model to open licensing, and edibles, extracts, and topicals ('Cannabis 2.0') became federally legal ^[10].
• 2022–2024: Health Canada conducted a legislative review of the Cannabis Act. The final expert panel report was released in March 2024 with recommendations but no immediate law changes ^[11].
• Toronto retail density: The number of licensed stores in Toronto has grown substantially since 2019; municipalities in Ontario were given a one-time chance to opt out and Toronto opted in.

As with any legal topic, rules change. Last verified: June 2024. Check the AGCO, OCS, City of Toronto, and Health Canada websites for the current position before relying on anything here.
