How it works

How cannabis is sold in St Catharines

A short history: one of Ontario's first licences

The city took up the opt-in question at a General Committee meeting on January 14, 2019 and did not opt out. When the AGCO issued its first operator licences that spring, The Niagara Herbalist at 33 Lakeshore Road was among them. The market has since grown to the 31 stores in our register-based count, all listed as authorized to open.

Legal age: 19+
Public possession: 30 g dried
Taxes: 13% HST plus federal excise duty
Online: ocs.ca only
US border: Niagara crossings: no cannabis in either direction
Lounges: None licensed in Ontario

Where are the stores in St. Catharines?

The AGCO register (September 2026) shows the downtown L2R postal area holding 12 of the city's stores, with the rest spread through the north end, the west end and the Glenridge area near Brock University.

Postal area	Stores	Rough area
L2R	12	Downtown and the older core (St. Paul St, Ontario St, Lake St, Niagara St)
L2S	6	West side along Fourth Ave and Vansickle Rd
L2N	5	North end toward Port Dalhousie and Lakeshore Rd
L2M	4	Northeast, Geneva St and Welland Ave
L2T / L2P	3	South, Glenridge Ave near Brock and Glendale Ave

Postal-area counts include the store listed under the alternate spelling “St. Catharines.” They're a snapshot, not a live map.

Niagara visitors and the border

St. Catharines is a common base for Niagara wine country and Falls trips, and the Rainbow, Whirlpool, Queenston-Lewiston and Peace bridges are all within a half-hour drive. Carrying cannabis across any of them without a Health Canada permit is a criminal offence under Canadian law, and US federal law also prohibits it. Use it on this side or leave it behind. Visitors from New York aged 19 or 20 can buy here with a passport, since Ontario's age is 19.

Checking a store before you buy

Look for the AGCO authorization posted in the store and the excise stamp on every package. Unstamped edibles, cash-only “members clubs” or websites promising mail delivery outside ocs.ca are grey-market. We track problem sellers on the Verdex Red List. Our what to bring and ask on a first dispensary visit explains ID and payment, and Ontario cannabis rules and ratings covers where you may consume under the Smoke-Free Ontario Act, which rules out patios, enclosed public spaces and vehicles. Thinking about your own use? The cannabis use check is a quick start.
