Can a landlord change a lease agreement?
Last updated: October 13, 2026
Short answer
Not on their own: in every province covered here, a signed lease can be changed only if the landlord and tenant both agree, apart from the few changes the law itself allows, mainly a rent increase given with proper notice. The core terms each province writes into every tenancy cannot be changed even by agreement, and a clause that waives a tenant's rights is void. House rules are the main grey area: Manitoba, Saskatchewan and Nova Scotia let a landlord add reasonable rules, while Alberta needs the tenants' written consent. New Brunswick also lets a landlord change terms other than the rent once a tenant has lived there five years or more, on three months' written notice.
What a landlord can and cannot change, by province
Rent increases follow their own rules, including whether rent can go up during a fixed term. See how much a landlord can increase rent and whether a landlord can raise the rent anytime. For every other term, the picture looks like this:
| Province | Can the landlord change terms alone? | Changes the law allows without the tenant's agreement |
|---|---|---|
| Alberta | No; changes should be in writing and signed by both | A rent increase with proper notice; new house rules only with the tenants' written consent |
| British Columbia | No; standard terms can never change, and other changes must be in writing and initialled by both | A legal rent increase, restricting a non-essential service or facility, or an arbitrator's order |
| Manitoba | No; changes should be in writing and initialled by both | A lawful rent increase; reasonable written rules made known to the tenant |
| Saskatchewan | No; the standard conditions can never change | A rent increase served under the Act, an Office of Residential Tenancies order, or reasonable written rules |
| Ontario | No; changes must be agreed in writing | Rent increases and reductions that the Act allows or requires |
| New Brunswick | No, for most tenancies; any alteration of the standard lease is void | After 5 or more consecutive years (and on mobile home sites), any term except the rent, on 3 months' written notice, if reasonable and fair |
| Nova Scotia | No; a fixed-term lease changes only if both agree, preferably in writing | Changing rules on 4 months' notice before the anniversary date; stopping a service only with proper rent increase notice or the Director's permission |
| Prince Edward Island | No; the Division 4 provisions can never change | A rent increase, a service change the Act allows, or a Director's order |
| Newfoundland and Labrador | No | A rent increase under the Act; removing a service counts as a rent increase, and adding a paid service needs written agreement |
Can the landlord change the terms at renewal?
Renewal is where many tenants are asked to sign a new lease. In Ontario, a fixed-term lease that ends renews month to month on the same terms, and the tenant does not have to sign a renewal or new lease to stay. British Columbia works the same way unless there is a valid vacate clause, and a landlord cannot make a tenant who wants to go month to month sign another fixed term. PEI treats the lease as renewed monthly with the same rights and obligations, and Manitoba requires the landlord of a written fixed-term tenancy to offer a renewal for the same term with the same benefits and obligations, subject only to a lawful rent increase, unless both sides agreed to something different.
Elsewhere, the end of a fixed term is a chance to negotiate. In Saskatchewan the landlord's Two Month Notice of Intention can offer new terms, and a tenant who does not accept in writing within one month must leave at the end of the term. In Alberta, New Brunswick and Nova Scotia a fixed term ends on its date and the parties can agree to a new lease; a tenant who stays on with the landlord accepting rent usually ends up on a new periodic tenancy. For what happens when a tenant says no, see what happens if a tenant refuses to sign a lease.
If your landlord wants to change your lease
Do not sign or initial a change you have not agreed to, and ask the landlord to put the proposal in writing. Keep paying rent on the existing terms. If the change is a rent increase, check it against whether a tenant can refuse a rent increase. If the landlord goes ahead anyway, you can ask your province's tenancy office to step in: BC tenants can seek dispute resolution when a landlord changes terms without consent, Manitoba's Residential Tenancies Branch and Saskatchewan's Office of Residential Tenancies can rule on whether a new rule is reasonable, and a New Brunswick tenant served with a notice changing terms can ask a residential tenancies officer to review it within 15 days.
Changing a lease in each province
Alberta
No. Once both sides agree to the terms, the agreement cannot be changed unless both agree or the law allows it, such as a rent increase with proper notice. Any change should be in writing and signed by both. A tenant cannot waive rights under the Act, and the Act prevails over a conflicting term.
House rules follow the same idea: a landlord can add or change rules during the tenancy only with the tenants' written consent, and otherwise must wait until the tenancy ends. At the end of a fixed term, the parties can negotiate a new agreement, which can include a different rent, deposit or conditions.
British Columbia
No. The standard terms can never be changed or removed. Other terms can be added, removed or changed only if both sides agree, and the change must be in writing and initialled by both or it cannot be enforced. A landlord needs no agreement only for a legal rent increase, restricting or withdrawing a non-essential service or facility, or a change ordered by an arbitrator.
Trying to contract out of the Act has no effect, and a term that is inconsistent with the Act, unconscionable or unclear cannot be enforced. A tenant whose landlord changes other terms without consent can apply for dispute resolution with the Residential Tenancy Branch.

Manitoba
No. We found nothing in the Act that lets a landlord change the agreement alone, and the standard form says any change or addition should be agreed in writing and initialled by both. Any agreement that waives or restricts the Act is void, and a landlord who once let a breach slide can still enforce the term next time. A landlord cannot reduce a service included in the rent without the Residential Tenancies Branch's approval.
Rules are different: a landlord can add or change rules on use and occupancy if they are in writing, made known to the tenant and reasonable, with reasonable notice for a significant change. A tenant who finds a new rule unreasonable can ask the Branch to decide.
Saskatchewan
No. The standard conditions can never be changed or removed, and other terms change only if both sides agree. The exceptions are a rent increase served under the Act and a term covered by an Office of Residential Tenancies order saying the other side's agreement is not needed. A term that is inconsistent with the Act, unconscionable or unclear cannot be enforced, and an agreement that the Act does not apply is void.
A landlord may make and enforce rules about use, occupancy, services and facilities without the tenant's agreement, if they are in writing, made known to the tenant and reasonable; a tenant can ask the Office of Residential Tenancies to rule on them. A landlord also cannot give notice or refuse to renew just to increase the security deposit.
Ontario
No. Ontario's standard lease says that once it is signed, it can be changed only if the landlord and tenant agree to the changes in writing. The only exceptions are rent increases and reductions that the Residential Tenancies Act allows or requires. All sections of the standard lease are mandatory, and a lease term that conflicts with the Act is void, including a no-pet clause.
When a fixed term ends and nothing new is signed, the tenancy continues month to month on the same terms. The tenant does not have to sign a renewal or a new lease to stay, and a tenancy can end only in accordance with the Act.

New Brunswick
For most tenancies, no. Any alteration or deletion of the Standard Form of Lease is void, and additions are allowed only if both sides agree, they do not change a right or duty under the Act or the form, and they appear on both originals.
New Brunswick has one exception. Where the same tenant has lived in the premises for five consecutive years or more, and on mobile home sites, the landlord may change any term except the rent amount by serving at least three months' written notice, as long as the change does not conflict with the Act and is reasonable and fair. The tenant can apply in writing to a residential tenancies officer within 15 days to have the notice reviewed.

Nova Scotia
No. The Act applies despite any agreement, the statutory conditions apply despite any lease, and changing or deleting a required term of the standard lease is void. Nova Scotia's renting guide says a fixed-term lease can be changed only if the tenant and landlord both agree, and the agreement should be in writing.
Rules are handled separately: a landlord can change or repeal rules on four months' notice before the anniversary date, the rules must meet the Act's reasonableness test, and they cannot remove anyone's rights. A landlord also cannot stop providing a service such as heat, water or an appliance without proper notice of a rent increase or the Director's permission.
Prince Edward Island
No. A term can be added, removed or changed only if both the landlord and tenant agree, and the Division 4 provisions cannot be changed or removed at all. The PEI Rental Office says a rental agreement can be changed after the tenant moves in only if both parties agree or the Rental Office orders it, and any change must be consistent with PEI's rental laws.
The exceptions are a rent increase under the Act, a change to a service or facility that the Act allows, and a Director's order saying the other side's agreement is not needed. A tenant's waiver of rights under the Act is void.
Newfoundland and Labrador
No. We found nothing in the Act that lets a landlord change the terms of an existing agreement alone, and the Act and its statutory conditions apply despite any agreement to the contrary. Terms that break the Act cannot be enforced.
Services are covered by the rent rules: taking away a service or benefit counts as a rent increase, and a landlord can add a new paid service, such as parking, only if both sides agree in writing. A tenant has to follow house rules only if they are in writing, reasonable and given at signing, with copies of any amendments.

Related questions
Can a landlord change a contract after signed?
Not without the tenant's agreement. In every province covered here, a signed lease changes only by agreement, except for the changes the law itself allows, mainly rent increases with proper notice. Get any agreed change in writing: BC makes an unwritten or uninitialled change unenforceable, and Ontario's standard lease requires changes to be agreed in writing.
Can a landlord change a lease while it is in effect?
Only with your agreement, or through a route the law sets out. Those routes are narrow: a legal rent increase, a service change some provinces allow, or a tribunal or Director's order. New Brunswick is the main exception, where a landlord can change terms other than rent after a tenant has stayed five or more consecutive years, on three months' written notice. Changes to the rent during a fixed term follow separate rules, covered in whether a landlord can raise the rent anytime.
Can a landlord change your lease without notice?
No. A landlord cannot change lease terms alone, with or without notice, outside the routes the law allows, and those routes all come with written notice. Rent increases need advance written notice in every province covered here, New Brunswick's change for long tenancies needs three months' written notice, and Nova Scotia's rule changes need four months' notice before the anniversary date. See how much a landlord can increase rent for the notice periods.
My landlord wants to change my lease, what should I do?
Ask for the proposed change in writing and take time to read it. You do not have to agree, and you should keep paying rent on the existing terms. If you do agree, make sure the change is written down and signed or initialled by both of you. If the landlord tries to impose it anyway, contact your province's tenancy office, such as BC's Residential Tenancy Branch, which takes disputes when a landlord changes terms without consent.
Can a landlord change a lease during the period if I agree?
Yes, as long as the change does not touch the terms the law makes mandatory and does not take away your rights under the Act. BC's standard terms, Saskatchewan's standard conditions and PEI's Division 4 provisions cannot be changed even by agreement, and an agreement to give up a right under the Act is void everywhere covered here. Put the change in writing and have both sides sign or initial it.
Can a landlord change a month to month lease?
The same rule applies: terms change only by agreement or through a route the law allows, such as a rent increase with proper notice. A month-to-month tenancy is not an opening to rewrite the lease. In Nova Scotia a periodic lease renews automatically when no notice is given, and a landlord can give notice to quit only on the grounds the Act lists.
Can a new landlord change my tenancy agreement?
No. In British Columbia, Ontario, New Brunswick and PEI, a sale does not end a tenancy by itself, and the buyer takes over as your landlord under the same agreement and the same rules on changing it. Check your province's tenancy office for the rule where you live. In Ontario, the Act says lease covenants run with the land, and in PEI a new landlord must tell the tenant in writing its name, address for service and the deposit it holds. See what to do if your landlord is selling the house.
Can a landlord add new rules after I signed the lease?
It depends on the province. Alberta lets a landlord add or change rules during the tenancy only with the tenants' written consent. Manitoba and Saskatchewan allow new rules that are in writing, made known to the tenant and reasonable, and the tenant can ask the tribunal to rule on them, while Nova Scotia allows rule changes on four months' notice before the anniversary date. In Newfoundland and Labrador, the standard agreement ties the tenant to rules given at signing and copies of any amendments.
Can a landlord take away parking or laundry?
Not freely. Manitoba bars a landlord from reducing a service included in the rent without the Residential Tenancies Branch's approval, Nova Scotia requires proper rent increase notice or the Director's permission, and Newfoundland and Labrador treats taking away a service or benefit as a rent increase. BC allows a landlord to restrict or withdraw a non-essential service or facility under the Act's conditions, and PEI allows service changes only as its Act sets out. Ask your tenancy office before accepting a cut.
What can a landlord do without a lease?
No more than with one. An oral tenancy is still covered by the Act in every province covered here (most also cover implied ones), and in Manitoba, New Brunswick and Nova Scotia it is treated as including the standard form's terms. The landlord still needs the tenant's agreement to change terms, must follow the Act's rent increase rules, and can end the tenancy only with the notice the law allows and, outside Newfoundland and Labrador, only for a reason the law allows. See whether you can be evicted without a lease.
How to write a lease amendment?
We found no government amendment form in the sources we reviewed, so a short written document that both sides sign is the usual way. What the law asks for differs a little: Alberta says changes should be in writing and signed by both, BC and Manitoba say initialled by both (in BC an unwritten or uninitialled change cannot be enforced), and Ontario requires the change to be agreed in writing. In New Brunswick an addition must appear on both originals and cannot change a right or duty under the Act or the standard form, and in Nova Scotia an extra term is void unless it appears on both parties' copies.
SQRFT's advice: name the landlord, the tenants and the address, give the date of the original lease, quote the clause being changed and the exact new wording, say when the change starts, then have everyone sign and date it and keep a copy each. An amendment cannot change or remove the standard terms or contradict the Act, and a rent change still has to follow the rent increase rules.
Can a landlord take someone off the lease?
Not on its own. We found no rule in the Acts we reviewed that lets a landlord remove a tenant's name alone, and the rules we reviewed treat a signed lease as something that is normally changed by agreement, so taking a name off in practice would mean the landlord and everyone on the lease agreeing in writing, usually through a signed amendment or a new lease. That is SQRFT's reading of the rules on this page, not a separate statutory rule.
A landlord who wants a tenant gone has to use one of the notice grounds and the process that goes with it, as set out in what reasons a landlord can evict you for. If you are the one who wants out, ask in writing and see how to get out of a lease agreement.
Can a landlord void a lease?
Not a whole signed lease at will. A tenancy ends by agreement or in the ways the Act allows, such as a notice on a permitted ground followed by the province's process; Ontario says a tenancy can end only in accordance with the Act, and New Brunswick says a landlord cannot simply end a fixed term early. What can be void is an individual clause. A term that conflicts with the Act is void in Ontario, Manitoba, Nova Scotia and Newfoundland and Labrador, cannot be enforced in BC and Saskatchewan, and in New Brunswick any alteration of the standard form is void. In Alberta the Act prevails over a conflicting term, and a tenant's waiver of rights under it is void.
The rules we reviewed speak of the individual clause being void or unenforceable and do not say the whole lease falls with it; if you are unsure how a void clause affects the rest of your lease, ask your tenancy office. We found no rule on a landlord cancelling a lease before the tenant moves in, so ask your province's tenancy office about that case.
