Ending a lease before it expires can be costly. In Alberta, residential tenancies are governed by the Residential Tenancies Act (RTA). Commercial tenancies are governed by the lease contract and common law. The financial obligations of a tenant depend on the circumstances of departure, the kind of tenancy and the lease agreement and the steps you take on your way out.

Here is what Alberta tenants need to know.

Legal Grounds for Breaking a Lease Without Penalty

Residential Tenancies

The RTA sets out specific situations where a tenant can end a tenancy early without facing an early-termination penalty.

Substantial breach by the landlord. A tenant may end a tenancy on at least 14 days’ written notice where the landlord commits a substantial breach — but only where an executive officer has issued an order under section 62 of the Public Health Act and the tenant reasonably believes the landlord has not complied. However, this termination route is narrower than many tenants assume. Absent a Public Health Act order, it is not available.

Uninhabitable or unsafe premises. Every Alberta lease includes the landlord’s covenant that the premises will meet at least the minimum housing standards under the Public Health Act. Where that covenant is breached but no Public Health Act order is granted, the tenant’s route is to apply to court, which can terminate the tenancy if the breach is significant enough, and award damages or rent abatement.

Family (domestic) violence. A tenant can end any tenancy including a fixed term if they believe their safety, that of a dependent, or that of a protected adult living with the tenant is at risk because of domestic violence. To do so, the tenant serves the landlord with written notice at least 28 days before the termination date. However, the tenant must at the same time serve a certificate signed by the designated authority confirming the grounds of the belief. The notice must be in writing, signed, state the termination date, and be given within 90 days after the certificate is issued. 

Standard notice to end a periodic tenancy. A weekly, monthly, or yearly periodic tenancy can be ended by either party on proper notice. A weekly tenancy requires roughly one week’s notice; a monthly tenancy requires one full tenancy month; and a yearly tenancy requires 60 days from a tenant. Any termination notice must be in writing, signed, identify the premises, and state the termination date. A fixed-term lease is different: it simply expires on the date specified, and there is no routine right to end it early on notice without one of the statutory grounds above.

Potential Penalties for Breaking a Lease

If you leave a fixed-term lease early without a qualifying ground, the exposure flows from the RTA’s repudiation provisions.

Liability for lost rent. When a tenant abandons or otherwise repudiates the lease, the landlord may accept the repudiation as ending the tenancy and recover damages for the lost benefit of the agreement — for a fixed term, until the term would have expired. On a tenant’s breach, the landlord may apply to court for unpaid rent, possession, and damages.

The landlord does have a duty to mitigate. This is the tenant’s most important protection. The landlord must make reasonable efforts to take reasonable steps to re-rent the unit. Once the landlord successfully re-rents the unit the tenant’s rent liability generally stops. The tenant is therefore typically liable for rent only until the unit is re-rented, plus reasonable related costs — not automatically for the entire balance of the term.

The exposure is compensatory, not punitive. A landlord can recover rent for the unexpired portion of the term but cannot pile on charges that simply penalize a tenant for leaving early. 

The landlord must return the security deposit, with any interest, within 10 days after the tenant gives up possession, or deliver the balance with a statement of account for amounts properly deducted. Deductions are limited. There should be no deductions for normal wear and tear. A deposit may be applied against unpaid rent or damages, but only to the extent actually owing. Deposit interest accrues at a prescribed annual rate. If the landlord withholds improperly, the tenant can sue to recover it. 

A landlord can also recover general damages for a tenant’s failure to vacate, and special damages where the landlord becomes liable to an incoming tenant and that loss was reasonably foreseeable. Claims typically proceed through the Residential Tenancy Dispute Resolution Service (RTDRS) or the courts.

The RTA itself does not report tenants to credit bureaus. However, if a landlord obtains a judgment and it goes unpaid, that judgment can surface on a credit report and in future tenant screening. The practical consequence of an unpaid judgment is what tends to affect credit and rental history.

Steps to Legally Break a Lease

Review your lease. Read the agreement for any early-termination or break clause, the notice it requires, and how it handles the deposit. The lease governs alongside the RTA for residential, and alongside common law for commercial. 

Give proper written notice. Where a statutory ground applies, follow its exact notice period and form. For a periodic tenancy, serve written, signed notice stating the termination date and giving the full required period. 

Negotiate with your landlord. Because the landlord must mitigate in any event, many are willing to agree to an early release — sometimes for a modest sum covering re-advertising or a short vacancy. A documented agreement is cleaner and cheaper than a dispute.

Document everything. Keep written records of all communications, your notice, the move-out inspection, and the condition of the unit. If a disagreement arises over rent or the deposit, this record is what you will rely on.

Alternatives to Breaking a Lease

Subletting and assignment

A tenant may assign or sublet with the landlord’s written consent, and the landlord cannot refuse without reasonable grounds. If the landlord does not respond within 14 days, consent is deemed given; a refusal must come with written reasons; and no fee may be charged for consenting. What counts as “unreasonable” depends on the circumstances, and a landlord is generally entitled to information about the proposed subtenant before deciding. 

One caution: an assignment transfers your interest but does not release you from the covenant to pay rent — you can remain liable if the new tenant defaults. 

Mutual termination

You and your landlord can simply agree to end the tenancy early (a surrender). Get it in writing, confirming the termination date and the treatment of the deposit, so there is no later dispute over outstanding rent. 

Mediation and dispute resolution

Where a disagreement cannot be resolved, a tenant may apply to the RTDRS instead of court. A tenancy dispute officer can help the parties settle and can record a settlement as an enforceable order.

Get advice early

The cost of breaking a lease often turns on small decisions made in the first few days. The notice you give, whether you pursue a sublet, and how you document the exit are all decisions that can impact the cost. If you are considering ending your lease early, speak with a lawyer before you act. Book a consultation with our team to review your lease and map the most cost-effective way out.

What About Commercial Leases?

The RTA applies only to tenancies of residential premises. Commercial leases are outside it. If you are breaking a lease for an office, store, warehouse, or other business space, none of the protections above apply. The parties’ rights and exposure come from the lease itself and the common law of contract.

The leading authority treats a commercial lease as a contract, not merely a conveyance of land, and gives the landlord the full range of contract remedies when a tenant repudiates. On a commercial tenant’s repudiation, the landlord generally has four mutually exclusive options: 

  1. do nothing and sue for rent as the lease continues; 
  2. terminate and sue for rent and damages accrued to the termination date;
  3. re-let on the tenant’s account; 
  4. or terminate on notice and claim damages for the lost benefit of the lease over the remaining term 

Mitigation in a commercial setting is somewhat disputed, but this question (raised in Canada Life Assurance Company v. Aphria Inc. 2024 ONCA 882)  has been granted leave to appeal by the SCC. While the current law does not oblige a commercial landlord to mitigate unless they terminate the lease, the safest course of action is to mitigate your expected losses. It is well settled that if the landlord does in fact mitigate despite not having a duty to do so, the Court will take into account the mitigation in determining damages. Further, as a landlord, even if you affirm the lease and allow rent to accrue knowing it will not be paid, it is likely the tenant will not be able to pay the judgment granted against them. Typically you will be better off to terminate the lease and try to re-let it, or re-let on the tenants account (with proper notice). However, based on your unique scenario the strategy may be different. It is important to speak with a lawyer who can guide you through the process.
