Smoke is one of the most expensive things a tenant can bring into a rental. It works its way into drywall, carpet, cabinets and ductwork, it drifts into neighbouring units, and it can turn an ordinary turnover into weeks of cleaning, sealing and repainting. Cannabis adds another question: since 2018, adults in Canada can legally grow a few plants at home, and some owners only discover that is happening in their basement at the next inspection.
This guide explains what Alberta law actually says about smoking, vaping and cannabis in rental properties, what the City of Grande Prairie adds, and how to write and enforce a lease rule that holds up. It draws on the Residential Tenancies Act (RTA), the Government of Alberta's RTA Handbook and Consumer Tips for tenants, the Tobacco, Smoking and Vaping Reduction Act, the Gaming, Liquor and Cannabis Act, the federal Cannabis Act and two City of Grande Prairie bylaws. It is general information, not legal advice, and the sources are listed at the end.
The short answer
Yes, an Alberta landlord can ban smoking and vaping of any substance, including cannabis, inside a rental and on the property, and can also ban growing cannabis. The Government of Alberta says so directly: "A landlord or condo board may prohibit the smoking of all substances including cannabis in their buildings or on their properties," and "a landlord may also prohibit the growing of cannabis in the rental agreement." The catch is that no provincial law bans smoking inside a private home for you. The ban works because it is a term of your tenancy agreement, so how and when you put it there matters more than anything else in this article.
What provincial law already covers
Alberta's Tobacco, Smoking and Vaping Reduction Act bans smoking and vaping in a "public place." That definition expressly includes "the common areas of a multi-unit residential facility, including patios, pools, other recreation areas and enclosed parking garages." If you own an apartment building or a fourplex with a shared hallway or laundry room, those areas are already smoke-free by law, whatever your lease says.
Inside the unit is different. Section 2(2) of the same Act says it does not apply to a building, or part of a building, used as a private residence. The one narrow exception, in section 4, treats part of a home as a workplace if a home business runs there and has employees who work in the home but do not live there.
Cannabis follows the tobacco rules. Section 90.28 of the Gaming, Liquor and Cannabis Act says no person may smoke or vape cannabis anywhere they are prohibited from smoking under the tobacco law, any other Act or a municipal bylaw, along with hospital, school and child care properties and areas near playgrounds and similar places. So common areas are off limits for cannabis smoke too. A private suite, a balcony, a yard or a detached garage that belongs to a single rental is not covered by these provincial bans. That is the gap your lease fills.
What Grande Prairie adds
The City of Grande Prairie's Smoke Free Public Places Bylaw, C-1278, sets local limits on consuming cannabis in public: not anywhere tobacco smoking is banned, not on the downtown streets bounded by 100 or 101 Avenue between 102 Street and 98 Street, and not within 30 metres of public parks, recreation facilities, outdoor special events and places where children are playing, among others. The specified penalty on a violation ticket is $250. Like the provincial law, though, the bylaw says plainly that nothing in it prohibits a person from smoking, or from consuming cannabis, at a residence. The City will not enforce your no-smoking clause for you.
Growing is where Grande Prairie differs from much of Alberta. Section 4.3 of the City's Minimum Property Standards Bylaw, C-1293 (added by amendment C-1293A in 2018), says a person shall not produce a cannabis product on a property within the City without first obtaining a Cannabis Production Permit, and "produce" includes cultivating, propagating or harvesting plants. The City's cannabis page says the permit is free, is available from Enforcement Services at the Grande Prairie Police Service headquarters, and that each residence is limited to four plants. If your rental is in the County of Grande Prairie or another town, check that municipality's own bylaws; this permit requirement is a City rule.
The federal four-plant limit is per home, not per person
Section 12 of the federal Cannabis Act prohibits an adult from growing more than four cannabis plants at any one time in their dwelling-house, and section 12(5) makes that a household cap: if two or more adults live in the same home, the total still cannot exceed four. "Dwelling-house" includes the yard and outbuildings attached to the home. Plants must also come from legal seeds or plant material. AGLC's CannabisSense site adds that renters and people in multi-family buildings "might be restricted from growing cannabis in their homes based on rules established in rental agreements or condominium bylaws," and tells growers to check with their landlord first.
For an owner, the practical point is this. Four legal plants with a City permit are lawful for the tenant, but they are only allowed in your property if your lease allows them. More than four plants is not a lease question at all; it is a breach of federal law, and the RTA makes it a term of every tenancy that the tenant will not perform illegal acts in the premises.
Why owners care about growing, even when it is legal
The concerns are physical, not moral. Indoor plants add humidity, and AGLC's own home-grow advice tells growers to monitor humidity and use dehumidifiers, to watch their building's electrical and fire safety limits, and to keep carbon monoxide detectors in and around the grow area. Grow lights and fans on extension cords, moisture in a closet or basement, and odour that carries through shared walls are exactly the problems that show up later as damage. If you have read our guide to mould in Alberta rental properties, you will recognize the pattern. It is also worth asking your insurer whether a home grow, even a legal one, changes anything on your policy; our landlord insurance guide for Alberta owners covers the questions to ask.
Put the rule in the lease before it is signed
The cleanest time to ban smoking, vaping or growing is before the tenant signs. A clause in the written agreement is a term the tenant has accepted, and it is far easier to enforce than a sign on the wall. The RTA Handbook also allows house rules for all tenants and lists smoking as an example of a reasonable rule, but both landlord and tenant should have a copy, so attach any rules to the lease and have the tenant initial them.
Mid-tenancy changes are much harder. The June 2025 RTA Handbook says landlords can change or add rules during a tenancy "with the written consent of the tenants, but otherwise cannot impose new rules on a tenant until the tenancy ends." The Centre for Public Legal Education Alberta (CPLEA) makes the same point: a lease is a contract and can only be altered if both parties agree. If you inherited a tenant with a lease that is silent on smoking, you can ask for a signed amendment, or wait until a fixed term ends and offer a new agreement that includes the rule. You cannot end a periodic tenancy simply to add a new house rule; it is not one of the prescribed reasons for terminating a periodic tenancy.
What a good smoking and cannabis clause covers
Vague clauses cause most of the disputes. A tenant who agreed to "no smoking" may argue that vaping, a hookah or a cannabis edible was never mentioned. A clear clause defines smoking to include lit tobacco, cannabis and any other substance, plus vaping and e-cigarettes. It names the places it applies to: inside the unit, balconies and patios, the yard, any garage or outbuilding rented with the unit, and the common areas. It says whether growing cannabis is permitted, and if it is, that the tenant must hold any required City permit, stay within the four-plant household limit, and keep the grow from causing moisture, odour or electrical problems. It applies to the tenant's guests as well as the tenant. Our guide to the key terms of an Alberta lease and rental agreement covers the rest of the agreement this clause should sit inside.
Two limits apply no matter what you write. Section 3(1) of the RTA makes any waiver of a tenant's rights under the Act void, so a clause cannot, for example, let you enter whenever you smell smoke or skip the notice and termination rules. And a clause that tries to ban lawful, non-smoking cannabis use, such as edibles, is likely to be hard to justify; the Government of Alberta's guidance distinguishes smoking, which a landlord may prohibit, from non-smoking consumption, which "may be permitted."
If your rental is a condo, the bylaws apply too
Many Grande Prairie condo corporations have their own rules on smoking and growing. The RTA Handbook notes that section 53 of the Condominium Property Act requires tenants renting a condo to comply with all condo bylaws, whether or not they are in the tenancy agreement. The two layers work together: your lease can be stricter than the bylaws, but it cannot permit something the bylaws prohibit. Give the tenant a copy of the current bylaws at signing. Our guide to renting out a condo in Grande Prairie explains the notice and deposit rules that come with condo rentals.
Medical cannabis and the duty to accommodate
Owners often ask whether a tenant with a medical authorization can ignore a no-smoking clause. The RTA Handbook's position is that restrictions on medical cannabis in rentals have not been settled by Alberta courts or legislation, that medical users have smoke-free options such as edibles and oils, and that a landlord enforcing a no-smoking rule is "only limiting the methods" of use. It adds that a tenant who keeps smoking in breach of the rules may be committing a substantial breach.
The Alberta Human Rights Commission is clear that landlords have a duty to accommodate needs related to a protected ground, including disability, to the point of undue hardship, and that the person asking for accommodation must cooperate in the process. One published example is Zahorouski v. Accredited Condominium Management, 2019 AHRC 41, as summarized by the law firm McLennan Ross: a condo owner with a medical authorization who smoked in his unit and on his balcony had his complaint dismissed because he gave no evidence that he needed to smoke rather than use another form of cannabis, and had not meaningfully taken part in the accommodation efforts. That was a condo case, not a tenancy, and every accommodation request turns on its own facts. If a tenant raises a medical need, take it seriously, ask for enough information to understand it, discuss alternatives in writing, and get advice before refusing.
Enforcing the rule: document first
Start with evidence and a written warning. Note the dates and times of complaints from neighbours, any smell in common areas, burn marks or ash outside, and what you saw during inspections. If you need to see inside, follow the entry rules: a routine inspection requires at least 24 hours' signed written notice and must be between 8 a.m. and 8 p.m., not on a Sunday or holiday. Our guide to landlord right of entry in Alberta explains the notice in detail. Smelling smoke from the hallway is not, by itself, an emergency that lets you walk in.
Then send a written notice that identifies the clause, the breach and what you expect to change. Most tenants stop once the rule is clearly stated in writing. Keep copies of everything.
When smoking becomes grounds to end a tenancy
A single cigarette on the balcony is unlikely to justify ending a tenancy. Under the RTA, a landlord can serve a 14-day notice for a "substantial breach," which means either a breach of one of the tenant covenants in section 21 or a series of breaches of the tenancy agreement whose cumulative effect is substantial. The section 21 covenants include not significantly interfering with the rights of the landlord or other tenants, not performing illegal acts in the premises, not endangering persons or property, and not doing or permitting significant damage. Smoke that persistently drifts into a neighbour's unit, a grow over the legal limit or one that creates a fire hazard, or repeated breaches after written warnings can fit those definitions. A first, minor breach usually will not.
The 14-day notice must be in writing, be signed, and set out the reasons and the termination date. For a breach other than non-payment of rent, the tenant can make the notice ineffective by serving a written objection with reasons before the termination date, and the landlord then has to apply to the Residential Tenancy Dispute Resolution Service (RTDRS) or the Court of Justice. Where a tenant has done or permitted significant damage, section 30 allows a 24-hour notice, but that is reserved for serious situations and comes with its own court-confirmation steps if the tenant does not leave. Our guide to the RTDRS for Alberta landlords explains how those hearings work.
Smoke damage and the security deposit
Smoke damage is one of the deductions the Government of Alberta specifically recognizes. The RTA Handbook lists "food, dirt or nicotine on walls, cupboards or appliances" and "tears or burns on carpets" as examples of damage beyond normal wear and tear that can be deducted from the deposit. The condition for that is strict: deductions for damage are only allowed if proper move-in and move-out inspection reports were completed, within one week of move-in and move-out, with the statements the regulation requires. Photos at move-in, including walls, ceilings, window coverings and carpet, make the difference when a tenant disputes a smoke-cleaning charge. If the cost exceeds the deposit, you can claim the balance through the RTDRS or court. Our Alberta security deposit guide covers the timelines for returning the deposit and the statement of account.
Screening and setting expectations
The easiest smoking problem to solve is the one you never have. Tell applicants about a no-smoking or no-grow rule in the listing and again at the showing, so the people who apply have already accepted it. Ask previous landlords whether there were any smoke or odour issues at move-out. Our tenant screening guide for Grande Prairie covers what to ask. Applying the rule consistently to every tenant also protects you if a dispute ever reaches a hearing.
A quick checklist for owners
Decide your policy before you list: smoking, vaping and cannabis smoking inside and on the property, and whether growing is allowed at all. Write it into the lease with clear definitions and locations, and give the tenant a copy of any house rules and condo bylaws. For an existing tenancy, get any new rule agreed in writing or add it at renewal. If you allow growing within City limits, require the tenant to hold the City's Cannabis Production Permit and stay within four plants per home. Complete detailed move-in and move-out inspection reports with photos. Document every breach, warn in writing first, and use the RTA's notice and dispute process rather than self-help.
