Ottawa is one of the most confusing cities in Canada to answer this question in — and that's not an exaggeration. Three levels of government own land inside city limits, and they don't all have the same rules. You can be standing in a park, take three steps, and technically change which rulebook applies to you.
So here's the clear version, current for 2026: where cannabis consumption is allowed in Ottawa, where it definitely isn't, and the local wrinkles that catch people out. We're a licensed cannabis store in Orléans, and this is the question our budtenders answer more than any other after "what should I buy."
Quick disclaimer that actually matters: rules change, and signage on site always wins. When in doubt, don't. Links to the official sources are at the bottom.
Ontario's general framework treats cannabis smoking and vaping much like tobacco — permitted in many outdoor public spaces, with a long list of exceptions. That's the provincial floor. Municipalities can then add restrictions on their own property, and Ottawa has.
Ottawa's Smoking and Vaping By-law (No. 2019-241) is the local layer, and its definition of "smoking" explicitly covers lighted cannabis, not just tobacco. Ottawa Public Health states plainly that smoking or vaping cannabis on City property — parks, arenas, recreation centres, libraries and pools — is not allowed.
Then comes the wrinkle no other Ontario city has: the National Capital Commission, a federal Crown corporation, owns a large amount of green space inside Ottawa — sections of the riverfront, parkway corridors, pathways and parkland. City bylaws do not govern federal land, which historically created the odd situation where two adjacent green spaces followed different rules. Because that jurisdiction is federal and its policy has evolved, treat NCC land as "verify first," not as a loophole.
Fines are not trivial: the city bylaw and the provincial act both carry meaningful penalties, and they escalate on repeat offences. [FINES]
Private residences you own. The simple answer, and the one that never surprises anyone.
A private yard, balcony or garage — subject to the point below about renting.
Some campsites. Parks Canada has permitted cannabis at campsites in the past; provincial and private campgrounds set their own rules. Check the specific campground before your trip rather than after.
Certain federal land — pending the NCC verification above. Do not treat "the city can't ticket here" as "this is permitted."
This is where most Ottawa disputes actually happen, and it has nothing to do with police. Landlords, condo boards and co-op boards can restrict smoking and vaping — including cannabis — in units and on balconies through leases and building rules. A smoke-free building clause is enforceable regardless of what provincial law permits.
Practical route if you're in a smoke-free building: non-smoked formats sidestep the issue entirely. Edibles, drinks, capsules and oils produce no smoke, no vapour and no smell — which is why they're a large and growing share of what we sell to apartment and condo residents.
Quebec is minutes across the bridge and runs a different system: a higher minimum age, different retail, and stricter public consumption rules. Ontario rules do not travel with your purchase. If you're heading to Gatineau or Gatineau Park, look up Quebec's current rules rather than assuming.
Even where consumption is legal, second-hand smoke affects the people around you — and children, older adults and people with breathing conditions most of all. Ottawa Public Health's guidance amounts to: be mindful of who's downwind. Good local practice: away from playgrounds and crowds, away from building entrances and open windows, and if someone asks you to move, just move. The legal framework in this city is under ongoing scrutiny, and how considerately consumers behave in public is part of what keeps it from tightening further.

Green Bank Cannabis, [ADDRESS-LINE], Orléans — a licensed cannabis store serving Ottawa East, open daily [HOURS], with same-day delivery in our zones. If you live somewhere smoke-free and want the formats that work in an apartment, that's a two-minute conversation at the counter. 19+ with valid ID.
Can you smoke weed in Ottawa parks?Not in City of Ottawa parks — the city's Smoking and Vaping By-law prohibits smoking and vaping, including cannabis, on City property such as parks, beaches, arenas, recreation centres, libraries and pools.
What about NCC land like the river pathways?NCC property is federal and is not governed by city bylaws, so different rules apply. The NCC's own regulations and any posted signage govern — check ncc-ccn.gc.ca before assuming consumption is permitted.
Can I smoke cannabis in my car?No. Consumption in a vehicle is prohibited, and cannabis must be kept sealed and out of the driver's reach — similar to open alcohol rules.
Can my landlord stop me from smoking cannabis in my apartment?Yes. Landlords, condo boards and co-op boards can restrict smoking and vaping through leases and building rules, regardless of what provincial law allows. Non-smoked formats such as edibles, drinks, capsules and oils avoid the issue.
How much cannabis can I carry in public in Ottawa?Up to 30 grams of dried cannabis, or the equivalent in other formats, for adults 19 and over.
Are the rules different in Gatineau?Yes. Quebec has a higher minimum age, different retail, and stricter public consumption rules. Check Quebec's rules before crossing rather than assuming Ontario's apply.
