Let me tell you about a mistake I see investors make all the time. They buy a rental property, find a tenant, and then pull some generic lease template off the internet. Maybe it’s a one-page document. Maybe it’s an American template that doesn’t even apply in Canada. They sign it, hand over the keys, and hope for the best.
Then something goes wrong—a busted pipe, an unauthorized roommate, a tenant who stops paying but won’t leave—and they look at their lease and realize it says nothing useful. Or worse, it includes clauses that aren’t even legal in their province.
Your lease is the foundation of your landlord-tenant relationship. It’s the document that defines who’s responsible for what, what’s allowed, and what happens when things go sideways. A good lease won’t prevent every problem, but it will give you a clear position when problems arise.
Let me walk you through the clauses that actually matter and which ones are enforceable in Canada’s biggest rental markets.
Standard vs. Custom Clauses: Know the Difference
First, you need to understand that in some provinces, you’re required to use a standard lease form.
Ontario mandated the Ontario Standard Lease (Form 2229E) effective April 30, 2018. Every residential tenancy in Ontario must use this form. You can add additional terms in the “Additional Terms” section, but the core lease must follow the government template. If you don’t use the standard lease and the tenant asks for one, you have 21 days to provide it or the tenant can withhold one month’s rent.
British Columbia doesn’t mandate a specific form, but the Residential Tenancy Branch provides a standard template that most landlords use. Custom clauses are allowed as long as they don’t conflict with the Residential Tenancy Act.
Alberta has no mandatory standard lease form. You have more freedom to draft your own agreement, though all clauses must still comply with the Residential Tenancies Act.
Regardless of province, here’s the critical rule: any clause that contradicts the provincial residential tenancy legislation is void. It doesn’t matter what both parties signed. If the law says a clause is unenforceable, it’s unenforceable. Full stop.
The Essential Clauses
1. Rent Amount, Due Date, and Payment Method
This seems obvious, but you’d be surprised how many leases are vague about this. Spell out:
- The exact monthly rent amount
- The day rent is due (typically the 1st of the month)
- Accepted payment methods (e-transfer, post-dated cheques, direct deposit)
- Where rent should be sent or deposited
Pro tip: Specify e-transfer as your preferred method and include your email address. E-transfers create automatic records with timestamps. Cheques bounce, cash can’t be proven, but an e-transfer has a clear digital trail. If you ever need to prove non-payment at a tribunal hearing, e-transfer records are gold.
Also note: in Ontario, you cannot require post-dated cheques. The tenant can choose to provide them, but you can’t make it a condition of the tenancy.
2. Maintenance and Repair Responsibilities
This is where a lot of disputes start. The lease should clearly define:
- Landlord responsibilities: Structural repairs, major systems (HVAC, plumbing, electrical), appliances included with the unit, common areas
- Tenant responsibilities: General cleanliness, reporting maintenance issues promptly, minor items (light bulbs, smoke detector batteries, furnace filters)
- Response timelines: How quickly you’ll respond to emergency vs. non-emergency repair requests
- How to submit maintenance requests: In writing (email or a maintenance portal) so there’s a record
Here’s a clause I use: “The tenant shall promptly notify the landlord in writing of any damage to or defect in the rental unit or the building. The tenant shall not attempt repairs to the unit’s systems, appliances, or fixtures without prior written consent of the landlord.”
That second sentence matters. You don’t want a tenant trying to fix the plumbing themselves and causing $5,000 in water damage.
In all three provinces, the landlord is legally required to maintain the property in a good state of repair and comply with health and safety standards, regardless of what the lease says. You can’t contract out of this obligation.
3. Tenant Insurance Requirement
This is one of the most important clauses in your lease, and many landlords skip it.
Require the tenant to carry tenant insurance (renter’s insurance). A typical policy costs the tenant $20-$40/month and covers:
- Their personal belongings (theft, fire, water damage)
- Liability coverage (if they cause damage to the unit or injure someone)
- Additional living expenses (if the unit becomes uninhabitable)
Here’s why this matters to you as the landlord: if a tenant causes a fire or a flood, your landlord insurance covers the building. But if the damage was caused by the tenant’s negligence, your insurance company may try to subrogate (recover costs) from the tenant. If the tenant has insurance, their policy handles it. If they don’t, you’re chasing an uninsured person for potentially tens of thousands of dollars.
Enforceability note: In Ontario, the LTB has ruled that requiring tenant insurance is generally enforceable as an additional term in the standard lease, as long as it doesn’t create an unreasonable barrier. In Alberta and BC, it’s also enforceable. Include a clause requiring the tenant to provide proof of insurance before move-in and maintain it throughout the tenancy.
Sample clause: “The tenant shall obtain and maintain throughout the tenancy a comprehensive tenant insurance policy with a minimum of $1,000,000 in personal liability coverage. The tenant shall provide proof of insurance to the landlord prior to the commencement of the tenancy and upon each renewal.”
4. Subletting and Assignment
Your lease needs to address what happens if the tenant wants to leave before the lease ends but doesn’t want to break it.
Subletting means the tenant lets someone else live in the unit temporarily while they’re away (they intend to return).
Assignment means the tenant transfers the lease to a new person entirely (they’re not coming back).
In Ontario, you cannot unreasonably refuse a request to assign or sublet. If you refuse assignment in general, or you don’t respond within 7 days, the tenant can give you 30 days’ notice and leave. Refusing one proposed assignee does not automatically create that right. An unreasonable refusal of a specific person is challenged at the LTB. You can charge the tenant a reasonable fee to cover your costs of processing the assignment (credit check, reference checks).
In Alberta, subletting and assignment terms are more flexible. You can include specific conditions in the lease.
In BC, the tenant needs your written consent to assign or sublet, and you cannot unreasonably withhold it.
Key clause to include: “The tenant shall not assign the lease or sublet the rental unit without the prior written consent of the landlord. The landlord’s consent shall not be unreasonably withheld. The tenant shall be responsible for any costs associated with processing the assignment or sublet, including credit checks and reference verification.”
5. Pet Policy
As I covered in my article on provincial laws, enforceability varies:
- Ontario: No-pet clauses are void and unenforceable. You can include language about pet-related responsibilities (cleaning, damage, noise) but you can’t prohibit pets.
- Alberta: No-pet clauses are enforceable. You can prohibit pets entirely or allow specific types with conditions.
- BC: No-pet clauses are generally enforceable (service animals excepted). If you allow pets, you can collect a pet damage deposit of up to half a month’s rent.
Even in provinces where you can’t ban pets, include a clause about pet responsibilities: “The tenant is responsible for any damage caused by their pet(s) beyond normal wear and tear. The tenant shall ensure their pet(s) do not disturb the reasonable enjoyment of other tenants or neighbours.”
6. Joint and Several Liability
If you’re renting to more than one person—a couple, roommates, whatever—this clause is essential.
Joint and several liability means each tenant is individually responsible for the full rent amount and all lease obligations. If one roommate moves out and the other stops paying, you can pursue either or both of them for the full amount.
Without this clause, you might only be able to collect each person’s “share” of the rent, which makes enforcement much harder.
Sample clause: “All tenants named in this lease are jointly and severally liable for all obligations under this agreement, including the full amount of rent. The departure of one tenant does not release them from liability unless a written agreement is executed by all parties releasing that tenant from the lease.”
This is enforceable in all three provinces.
7. Early Termination
What happens if the tenant wants out early? Your lease should address this clearly:
- Fixed-term lease: In most provinces, the tenant is obligated for the full term. However, practically speaking, if a tenant wants to leave, your best option is usually to let them go and find a replacement rather than fighting it.
- Early termination fee: Some landlords include a clause allowing the tenant to break the lease by paying a specified amount (typically two months’ rent). This is a grey area—in Ontario, the LTB may not enforce a pre-set termination fee. In Alberta, it’s more enforceable. In BC, the tenant is responsible for rent until you re-rent the unit or the lease ends, whichever comes first.
What actually works: Include a clause that says the tenant must give written notice, assist in finding a replacement tenant, and is responsible for rent until a suitable replacement is found or the lease expires. This is the most practical and enforceable approach across all three provinces.
The key word is “mitigation.” As a landlord, you have a duty to mitigate your losses—meaning you need to make reasonable efforts to re-rent the unit. You can’t just sit back and collect rent from a tenant who left early without trying to find someone new.
8. Entry and Access
Provincial legislation limits when and how you can enter the rental unit. Your lease should reflect these rules:
| Province | Written Notice Required | Emergency Entry |
|---|---|---|
| Ontario | 24 hours (entry between 8am-8pm) | No notice needed |
| Alberta | 24 hours (with some exceptions) | No notice needed |
| BC | 24 hours (entry between 8am-9pm) | No notice needed |
Include a clause that restates the legal requirements and adds practical details: “The landlord shall provide 24 hours’ written notice before entering the unit, specifying the date, time, and reason for entry. Entry shall occur between [legal hours]. In the event of an emergency, the landlord may enter without notice.”
Don’t try to include clauses giving you broader entry rights than the law allows. They won’t hold up.
9. Smoking and Cannabis
Since cannabis legalization in 2018, this has become a real issue for landlords.
- Ontario: You can include a no-smoking clause (including cannabis) in the lease, and it’s generally enforceable as a reasonable additional term.
- Alberta: No-smoking clauses are enforceable.
- BC: No-smoking clauses are enforceable.
Sample clause: “Smoking of any substance, including tobacco and cannabis, is prohibited inside the rental unit and on the balcony/patio. The growing of cannabis plants inside the rental unit is prohibited.”
This clause protects your property from smoke damage, which can cost thousands to remediate (painting, replacing carpet, ozone treatment).
10. Parking and Storage
If the property includes parking or storage, define the terms:
- Which spaces are assigned and which are shared
- Whether parking is included in rent or costs extra (and how much)
- Rules about vehicle storage (no abandoned vehicles, no major repairs in the parking area)
- Storage locker assignments and restrictions (no hazardous materials, no flammable items)
If parking and storage are separate from the lease (billed separately), keep them as a separate agreement. This gives you more flexibility to adjust pricing and terms without modifying the lease itself. In Ontario, parking included in the lease is subject to rent control just like the unit rent.
Clauses You Think Are Enforceable (But Aren’t)
Let me save you some grief. Here are clauses that landlords commonly include but that tribunals will toss out:
“No guests for more than X days.” In all three provinces, tenants have the right to have guests. You can’t limit how long a guest stays, though if someone moves in permanently, they may need to be added to the lease.
“Tenant waives right to file with the tribunal.” You cannot contract out of a tenant’s right to access the dispute resolution process. This clause is void everywhere.
“Landlord is not responsible for maintenance of [legally required item].” You can’t offload your legal maintenance obligations to the tenant through a lease clause.
“Rent increases will be X% per year.” In Ontario and BC, rent increases are governed by legislation, not the lease. Even if the tenant agrees to a specific increase schedule, it’s unenforceable if it exceeds the guideline (for controlled units).
“No children.” This is human rights discrimination. Don’t even think about it.
Building Your Lease
Here’s my practical advice:
-
Start with the standard form if your province requires one (Ontario) or provides one (BC). In Alberta, start with a reputable template from a landlord association like the Alberta Residential Landlord Association.
-
Add your custom clauses in the additional terms section. Focus on the essentials I covered above.
-
Have a real estate lawyer review it. A one-time review costs $300-$500 and is worth every penny. They’ll catch clauses that might be unenforceable in your province and suggest language that will hold up at a hearing.
-
Update it annually. Laws change. The lease you used in 2022 might have clauses that are no longer valid in 2026. Review your template at least once a year.
-
Use the same lease for every property. Consistency makes your life easier and reduces the chance of errors.
Your lease is a business document. Treat it like one.
