Can I break my lease if my apartment has mold?
Last updated: October 13, 2026
Short answer
Sometimes, but not everywhere and not just because you found mold or pests. In Manitoba, Saskatchewan and Newfoundland and Labrador a tenant can end the tenancy by notice when the landlord's breach is serious enough, and in British Columbia after written notice and a reasonable time to fix it. In Ontario, New Brunswick, Nova Scotia and PEI the route is an order from the tenancy tribunal or officer, and Alberta is the same unless a public health order has been issued, so ending it yourself with a plain notice is risky. Do not stop paying rent or move out before you know which route applies.
Why mold and pests do not automatically end a lease
We found no rule in the provinces covered here that names mold as a ground to leave. What the law does say is that the landlord must keep the unit fit to live in and meet health and housing standards, and a serious breach of that duty can end the tenancy. Whether it ends by your notice, by the landlord's agreement, or by an order depends on the province.
- Tell the landlord in writing first. Most routes start with a dated written request that describes the problem and gives time to fix it. We found no written-request condition in Saskatchewan or Nova Scotia, but a written request is still the best evidence (SQRFT advice, not law).
- Pests are usually the landlord's job. Government guidance in Saskatchewan and PEI puts the treatment cost on the landlord unless the tenant caused the problem, Alberta lets a landlord claim costs from a tenant shown to be responsible, and Manitoba lets a landlord claim the cost of a second spray if the tenant did not prepare. Tenants must keep the unit clean, and several provinces expect them to report pests (check the province answer below).
- Mold is a mix. A tenant handles ordinary cleaning of small spots (British Columbia's repairs page names minor mold on windowsills, tubs and showers). Mold from leaks, damp or poor ventilation is a building problem for the landlord.
SQRFT advice (not law): photograph the problem with dates, keep copies of every message, and ask your local public health office or municipal inspector to look at it. Their report is strong evidence.
Can you end the tenancy yourself, by province
| Province | Can the tenant end it by notice? | Otherwise |
|---|---|---|
| Alberta | 14 days' notice, only after a public health order about the landlord's substantial breach | RTDRS or court can end the tenancy for a significant breach |
| British Columbia | Yes, for a breach of a material term not fixed in a reasonable time after written notice | Dispute resolution for repair orders and rent reductions |
| Manitoba | Yes: 5 days if a health or safety risk; immediate if uninhabitable | Order to repair; compensation claim |
| Saskatchewan | Yes, for a material breach after a reasonable time to fix; one day's notice can apply, e.g. uninhabitable | ORT application (order to comply, damages) |
| Ontario | We found none for this reason | T6 application; the Board can end the tenancy |
| New Brunswick | No; the tenant applies to an officer to end it | Complaint to a residential tenancies officer |
| Nova Scotia | No notice right for this reason | Director can order repairs, compensation or an end date |
| Prince Edward Island | No notice right for this reason | Application to the Director; the Director can end it |
| Newfoundland and Labrador | Yes, immediate notice for a breach of the repair and fitness duty | Repair order from the Residential Tenancies Office |
This table is a summary. The province answers below give the conditions that go with each route.
What to do about rent while this is going on
Keep paying rent unless the law or an order says otherwise. The provinces covered here do not give tenants a general right to hold rent back for mold or pests. Ontario's Board says a tenant should not withhold rent and can ask to pay rent into the Board instead, and Nova Scotia's guide says rent cannot be withheld. Where a rent reduction or payment into trust is available, it comes from an order. Manitoba suspends rent only while a government order requires the tenant to vacate.
Moving out first can hurt your case. If a tribunal or officer might end the tenancy, ask them or the tenancy office before you leave. SQRFT advice (not law): get the inspection, the written complaint and the landlord's reply on file before you decide.
Mold and pests: what you can do in each province
Alberta
The Act and regulations do not name mold. The landlord must meet the minimum housing standards, which cover keeping the building waterproof and basements free of water, and must keep the premises free of insect and rodent infestations. A tenant must report an infestation and allow access for treatment. The landlord can enter on 24 hours' written notice to control pests, and can apply to RTDRS or court for reimbursement if the tenant caused the problem.
A tenant can end the tenancy on 14 days' written notice only where the landlord has committed a substantial breach and a public health order has been issued about it and the tenant reasonably believes the landlord has not complied. The notice is ineffective if the landlord objects within 7 days and is right that it has complied. Otherwise the tenant can apply to RTDRS or the Alberta Court of Justice to end the tenancy for a significant breach, plus damages or a rent reduction. RTDRS cannot order the landlord to do repairs.
British Columbia
The Residential Tenancy Branch says landlords are generally responsible for insects such as bed bugs, while other pests such as rodents depend on the local standards of maintenance bylaw. Minor mold on windowsills, tubs and showers is the tenant's to deal with, and tenants should report water damage straight away. There is no special health hazard notice that lets a tenant leave early.
The tenant's route is a written notice of the problem, and if the landlord has not fixed it within a reasonable period, the tenant can end the tenancy on a date after the landlord receives the notice (breach of a material term, s.45(3)). If the unit truly cannot be lived in, frustration of the tenancy may apply. A tenant can also apply for dispute resolution for repair orders, a rent reduction and compensation. A tenant cannot make ordinary repairs and charge the landlord without written agreement.
Manitoba
The landlord must keep the unit in a good state of repair, fit for habitation and meeting health and maintenance standards. The public health standard says an owner may not rent a dwelling unless it is free of insect pests and rodents. Pest control rules also come from municipal bylaws and The Public Health Act. The tenant must keep the unit reasonably clean, report pests, let the exterminator in and follow the preparation instructions.
A tenant can end the tenancy by notice without a tribunal order. If the landlord's breach poses a health or safety risk, the notice can take effect 5 days after it is given, with no prior warning needed. If the breach makes the unit or complex uninhabitable, it can take effect immediately. The usual repair route is a Tenant's Request for Repairs to the Branch, which can issue an order to repair. If a provincial or municipal order requires the tenant to vacate because the unit fails health, building or maintenance standards, rent is suspended while the order is in effect. We found no mold-specific rule in the Act.
Saskatchewan
The Act and regulations do not mention mold or pests. The landlord must keep the property in good repair and fit for habitation, and the government says treatment costs are generally the landlord's unless the tenant caused the problem. The tenant must keep reasonable cleanliness and sanitary standards. Public Health Inspectors can look at extensive mold and at rodent or insect infestations.
If the landlord breaches a material provision, the tenant can end the tenancy by written notice after giving the landlord a reasonable period to fix the problem, if it can be fixed. The standard conditions say this can be on one day's notice, with the reason stated, and give an uninhabitable unit as an example. The government form is Form 6a. Or the tenant can apply to the Office of Residential Tenancies for an order to comply, rent paid to the director to fund the fix, or damages.

Ontario
The landlord must keep the complex fit for habitation and meet health, safety, housing and maintenance standards, even if the tenant knew of the problem when signing. The provincial maintenance standards require the complex to be kept reasonably free of rodents, vermin and insects, and require walls and ceilings to be kept free of mould, mildew and other fungi. Where a municipality has its own property standards by-law, that by-law usually applies instead.
We found no rule letting a tenant end the tenancy on their own notice because of health or safety problems. The tenant can apply to the Landlord and Tenant Board on form T6, within one year of the conduct, and the Board can terminate the tenancy, order a rent abatement or order repairs. A tenant can also agree with the landlord to end it (N11) or give a normal notice. The Board says a tenant should keep paying rent.
New Brunswick
The Act does not mention mold, pests or bed bugs. The landlord's general duty is to keep the unit fit for habitation and meet health, safety and housing standards. Where a municipality has adopted the province's model maintenance code, a dwelling must be kept free of rodents and insects. The Department of Health bed bug sheets are guidance and tell tenants to report and prepare the unit for treatment.
A tenant cannot end the tenancy on their own notice for this reason. The tenant serves a written complaint, the landlord has 7 days to comply, and then the tenant notifies a residential tenancies officer. The tenant can then apply to the officer to end the tenancy, and the officer can serve a notice of termination after investigating, if satisfied that the landlord has failed to comply and is unwilling or not financially able to do so. The officer can order the landlord to pay up to one month's rent for the tenant's expenses, plus a refund of up to one month's rent paid while the unit was uninhabitable. The landlord cannot claim the lost future rent.

Nova Scotia
We found no mold-specific or pest-specific rule in the Act or regulations. The landlord must keep the premises in a good state of repair and fit for habitation and comply with health, safety and housing standards, which in practice means municipal by-laws. The tenant must keep the interior ordinarily clean. We found no official source that sets a tenant duty to report pests or prepare the unit for treatment.
A tenant cannot end the tenancy by notice just because the unit has mold or is unsafe. The route is to apply to the Director (Form J), who can order repairs, compensation, or that the tenancy end on a set date. For an urgent problem the tenant can ask for an emergency hearing (Form DR9). The health-based early exit (s.10C) is about the tenant's own health, and we could not confirm whether it can be used where a unit condition causes the decline, so ask the Residential Tenancies Program before relying on it. The guide says rent cannot be withheld.

Prince Edward Island
The owner must prevent and treat infestations, and the regulations name cockroaches, bedbugs, fleas, rats and mice. They also require buildings to be free from dampness and dwellings to be damp-proof. The tenant must report an infestation immediately, in writing, to both the owner and a public health official. The Rental Office says a licensed pest control company should do the treatment and the landlord pays, unless the landlord proves the tenant caused it.
The Act gives the tenant no notice right to leave early because of poor conditions. The tenant applies to the Director, who can order a rent reduction, compensation or an end to the tenancy, and urgent safety matters can be decided without a hearing. For emergency repairs, the tenant must contact the landlord's emergency contact, allow reasonable time, and can then have the repair done and claim reimbursement with receipts.
Newfoundland and Labrador
The Act does not mention mold or pests. The landlord must keep the unit in a good state of repair and fit for habitation and comply with health, safety and housing law, even if the tenant knew of the problem. In the municipalities listed in the Occupancy and Maintenance Regulations, every dwelling must be kept free of rodents, vermin and insects, and extermination ordered by the authority is at the owner's expense. Those regulations also require spaces to be kept free of dampness so as to prevent mildew.
If the landlord breaches the repair and fitness duty, the tenant can give written notice that the agreement is terminated, effective immediately, with no tribunal order needed first (s.21(1)). The Office's policy warns that immediate notice may not be justified if the landlord is already fixing an emergency. A tenant who wants to stay can apply for a repair order, a rent reduction or rent paid into trust, but the Office will not accept a repair application unless a written repair request has been served and the rent is up to date. A notice cannot be given verbally.

Related questions
Can I break my lease due to mold?
It depends on the province. Manitoba, Saskatchewan and Newfoundland and Labrador let a tenant end the tenancy by notice for a serious breach of the landlord's repair duty, and British Columbia does so after written notice and a reasonable time to fix. In Ontario, Alberta, New Brunswick, Nova Scotia and PEI the route runs through an order or a public health order. See the table above, and do not stop paying rent while you sort it out.
How to get out of a lease due to mold?
Report the mold to the landlord in writing and keep a copy. Give a reasonable time to fix it, and consider asking the public health office or municipal inspector to look at it. Then use your province's route: notice in Manitoba, Saskatchewan, Newfoundland and Labrador or British Columbia, or an application to the tribunal or officer elsewhere. Another option is a written agreement with the landlord to end the lease. See how to get out of a lease agreement.
How to break a lease for mold?
Do it in the steps the law sets for your province, not by simply leaving. A tenant who leaves with no legal ground may owe the landlord for the rent lost, so check your province's rule first. Where the law allows notice, it is written, states the reason, and follows a written request to fix the problem. Keep photos and copies of everything. See what if my landlord says I can't break my lease.
Can I break my lease due to black mold?
We found no rule in the provinces covered here that treats black mold differently from other mold. What counts is whether the problem makes the unit unfit or unsafe and whether the landlord was told and did not fix it. A public health or municipal inspector's report on the mold is strong evidence. In Alberta, a public health order is what opens the tenant's 14-day notice route.
Can I break my lease due to roaches?
Roaches are generally the landlord's responsibility to treat. Manitoba's pest guide names cockroaches and bed bugs, and PEI's regulations name cockroaches. Whether you can end the lease depends on the province: in Manitoba, Saskatchewan and Newfoundland and Labrador a serious uncorrected breach can allow notice, while in other provinces you apply to the tribunal or officer. Report it in writing and let the landlord treat it first.
How to get out of a lease due to cockroaches?
Start with a written report to the landlord, and prepare the unit for treatment as asked. If the landlord does not act, complain to public health or the municipality and use your province's repair route. If you want to leave, use the notice or order route in the table above, or ask the landlord for a written agreement to end the lease. In PEI the tenant must also notify a public health official in writing.
How to get out of a lease because of roaches?
The steps are the same as for any pest problem. Notify the landlord in writing, allow treatment, and keep records. If treatment does not work or the landlord refuses, the tenancy office or tribunal can order repairs, a rent reduction or, in some provinces, an end to the tenancy. Where the landlord proves the tenant caused the infestation, the landlord may claim the treatment cost.
Breaking a lease due to pest infestation, is it allowed?
It can be, but only on the grounds your province allows. A pest infestation that the landlord does not fix can be a breach of the duty to keep the unit fit to live in. That can support notice in some provinces or an order ending the tenancy in others. If the tenant caused the infestation, the tenant's position is weaker.
Can I withhold rent due to mice?
Generally no. The provinces covered here do not give a general right to hold back rent for mice, mold or other repair problems. In Ontario the Board says a tenant should not withhold rent, and Nova Scotia's guide says rent cannot be withheld. Rent reductions or payment into trust come from an order. British Columbia and PEI allow a tenant to arrange certain emergency repairs and claim the cost. See can I withhold rent from my landlord.
What if my landlord won't fix mold or pests?
Put the request in writing, give a reasonable time, and then use your province's route. That means an application to the tribunal or office in most provinces, a Tenant's Request for Repairs to the Branch in Manitoba, or a written complaint and then a notice to an officer in New Brunswick. A public health inspector or municipal inspector can also act. See what to do if a landlord refuses repairs.
Does my landlord have to remove mold?
If the mold comes from the building itself, such as a leak, damp or poor ventilation, fixing it is generally the landlord's job under the duty to keep the unit in repair (our reading of the repair rules, not a mold-specific rule). Ontario's housing standards regulation requires walls and ceilings to be free of mould, mildew and fungi (a municipal by-law may apply instead), Alberta requires a waterproof building and basements free of water, and Prince Edward Island requires damp-proof dwellings. In British Columbia, minor mold on windowsills, tubs and showers is the tenant's job to clean. We found no mold-specific rule in the Alberta, Manitoba, Saskatchewan, New Brunswick, Nova Scotia or Newfoundland and Labrador tenancy Acts we reviewed, so the general repair duty is the starting point there (in some Newfoundland and Labrador municipalities, regulations also require spaces to be kept free of dampness to prevent mildew). See what to do if your landlord refuses repairs.
Should I tell my landlord about mold?
SQRFT advice: yes, tell your landlord in writing. In Newfoundland and Labrador the Residential Tenancies Office will not accept a repair application unless a written request was served, the landlord did not repair within a reasonable time and the tenant's rent is not in arrears, and in British Columbia the end-of-tenancy route for a landlord's breach needs written notice and a reasonable time to fix it. British Columbia also asks tenants to report water damage immediately. We found no written-request condition for Saskatchewan or Nova Scotia, but a dated written request is still good evidence. Keep dated photos and copies of every message.
My landlord painted over mold, what can I do?
We found no rule that speaks to painting over mold specifically, but the landlord's duty to keep the unit fit and in repair still applies if the mold is still there. SQRFT advice: take dated photos, send a written request to deal with the cause, and consider asking a public health or municipal inspector for a report. If the landlord still does nothing, use your province's repair route, for example a T6 application in Ontario within one year.
Is it illegal to rent a house with mold?
We found no rule that bans mold by name, but a rental unit must be fit to live in and meet the housing standards in the province. In Ontario and Prince Edward Island the standards described above apply. In Alberta, an order under the Public Health Act can declare premises unfit, and once that happens no one may occupy them. If you think a unit is unsafe, ask your local public health or property standards office to inspect it.
