Ontario Cannabis Regulations
Hybrid (Public & Private)Federal Authority: Health Canada · Provincial Regulator: Alcohol and Gaming Commission of Ontario (AGCO)
Cannabis Regulation in Ontario
Ontario is Canada's largest cannabis market by population, serving over 15 million residents. Following federal legalization under the Cannabis Act (Bill C-45) on October 17, 2018, Ontario initially launched with online-only sales through the Ontario Cannabis Store (OCS) before opening private retail stores in April 2019. As of 2025, Ontario has over 1,700 authorized private retail cannabis stores — the most of any province — regulated by the Alcohol and Gaming Commission of Ontario (AGCO).
Retail Model: Private Retail with Government Wholesale
Ontario operates a hybrid model. The Ontario Cannabis Store (OCS), a Crown corporation under the Liquor Control Board of Ontario (LCBO), is the sole legal online retailer and wholesale distributor to private stores. Private retailers must obtain an Authorization from the AGCO under the Cannabis Licence Act, 2018. Stores must be standalone (no co-location with liquor or tobacco), and all product must be sourced exclusively from the OCS. Municipalities had the option to opt out of hosting cannabis stores, though the vast majority opted in.
Packaging Requirements
All cannabis products sold in Ontario must comply with federal packaging requirements under the Cannabis Regulations (SOR/2018-144). Packaging must be plain, single uniform colour, child-resistant, and tamper-evident. The standardized cannabis symbol (a red stop-sign shape with a cannabis leaf) must appear on all packages. Brand elements are limited to one brand name, one logo (no larger than the health warning), and no design elements that could appeal to young persons. Packaging cannot depict people, characters, or animals, and must not associate the product with glamour, recreation, excitement, or vitality.
Labeling Requirements
Labels must include the Health Canada health warning messages on a rotating basis, covering at least 30% of the principal display panel. Required information includes: THC and CBD content per unit and per package, equivalency information, net weight, lot number, packaging date, producer name and contact, and the standardized cannabis symbol. All label text must appear in both English and French as per federal requirements. Ontario does not impose additional provincial labeling beyond federal standards.
Advertising Restrictions
Cannabis advertising in Ontario is governed by Part 5 of the federal Cannabis Act and Ontario's own regulations. Informational promotion is permitted only where young persons are not allowed. No lifestyle advertising, testimonials, endorsements, or depictions of persons are permitted. Promotions cannot associate cannabis with glamour, excitement, or athletic or sexual prowess. Retail stores may display products and pricing in-store but exterior signage is strictly regulated by the AGCO — stores cannot have window displays visible from outside and cannot use imagery that promotes cannabis consumption.
Licensing Overview
Retail cannabis store operators must obtain a Retail Operator Licence and a Retail Store Authorization from the AGCO. The licensing process includes background checks, financial disclosure, a public notice period, and municipal consultation. Operators can hold up to 150 store authorizations (increased from the original 75-store cap). Licensed producers must hold a federal licence from Health Canada under the Cannabis Regulations. Ontario also permits cannabis consumption lounges in municipalities that allow them, subject to AGCO authorization.
Possession and Consumption
Adults 19+ may possess up to 30 grams of dried cannabis (or equivalent) in public. Home cultivation of up to 4 plants per household is permitted under the federal Cannabis Act. Cannabis consumption is prohibited in enclosed workplaces, enclosed public spaces, schools, playgrounds, hospitals, and vehicles. Ontario treats cannabis consumption similarly to tobacco under the Smoke-Free Ontario Act, 2017, allowing consumption in private residences and designated areas.

Who regulates cannabis in Ontario?

Can I sell cannabis online in Ontario?
Online cannabis sales in Ontario are exclusively operated by the Ontario Cannabis Store (OCS) at ocs.ca. Private retailers are not permitted to sell cannabis through their own websites or online platforms.
The OCS ships orders via Canada Post with age verification at delivery. Private retailers may offer click-and-collect services where customers order by phone or in person for pickup, but full e-commerce is reserved for the OCS.
What are the packaging requirements in Ontario?
Cannabis packaging in Ontario must comply with all federal Health Canada requirements: plain packaging in the prescribed colour, the standardized cannabis symbol, health warnings, child-resistant closures, and tamper-evident seals. Ontario's provincial excise stamp must be affixed to all products.
The AGCO also enforces rules about how products are displayed in retail stores — cannabis must be kept behind counters or in locked display cases, not accessible to customers without staff assistance.
What are the advertising restrictions in Ontario?
Cannabis advertising in Ontario follows federal Cannabis Act restrictions, with additional provincial enforcement by the AGCO. Lifestyle marketing, endorsements, and youth-appealing promotions are prohibited. Retailers cannot display cannabis or accessories in windows or areas visible from outside the store.
The AGCO issues specific guidelines on permissible in-store signage, digital menu displays, and promotional materials. Retailers face licence suspensions or fines for advertising violations.
How do I get a cannabis retail license in Ontario?
Cannabis retail licences in Ontario are called Retail Store Authorizations (RSAs), issued by the AGCO. Applicants must pass criminal background checks, provide a detailed store layout, meet municipal zoning requirements, and demonstrate financial fitness. There is no cap on the number of stores, but operators are limited to 150 retail locations each.
The application fee is $6,000 for the initial RSA plus $750 per additional store. The AGCO also conducts ongoing compliance inspections after licensing. Processing typically takes 4-8 weeks once all requirements are met.
What is the cannabis excise tax in Ontario?
Ontario applies the federal cannabis excise duty (the greater of $1.00/gram or 10% of the producer's selling price for dried flower) plus HST (13%) at the point of sale. Ontario receives 75% of the first $100 million in federal cannabis excise revenue under the Coordinated Cannabis Taxation Agreement.
The OCS also captures margin as the sole wholesaler, effectively adding to the cost structure. Ontario's overall tax and markup burden places it in the mid-range among Canadian provinces.
Can cannabis businesses use promotional products in Ontario?
The federal Cannabis Act strictly limits branded promotional products for cannabis businesses in Ontario. Branded merchandise cannot promote cannabis use, appeal to youth, or use lifestyle imagery. Items like branded lighters, rolling papers, trays, and apparel are subject to these federal restrictions.
The AGCO enforces additional rules at the retail level — stores cannot offer free samples, loyalty-based cannabis rewards, or inducements to purchase. Businesses should consult both Health Canada and AGCO guidelines before producing branded promotional items.
