Can Landlords Change Lease Rules After Signing in Saskatchewan?

Leases & Agreements Saskatchewan 4 min read · published March 09, 2026 Flag of Saskatchewan

Leases in Saskatchewan are legally binding, and both tenants and landlords have specific rights and responsibilities once a rental agreement is signed. But can landlords change lease rules after you’ve signed? Understanding this process under Saskatchewan law helps you protect your rights and enjoy stable, predictable housing.

Lease Amendments: What Tenants in Saskatchewan Need to Know

Once a lease or rental agreement is signed in Saskatchewan, it generally cannot be changed unless both parties—tenant and landlord—agree to the new terms. This means your landlord cannot simply update rules about pets, guests, use of facilities, or anything else mid-lease without your written consent.

Lease changes require mutual, written agreement. When negotiating, request a written amendment signed by both parties and attach it to the current lease; keep dated copies of any notices or emails discussing the change.
  • Fixed-term leases (e.g., a 12-month contract): The rules stay the same for the full lease unless both sides sign a new agreement.
  • Periodic (month-to-month) tenancies: Changes can only be made with proper written notice and in accordance with the law.

If your landlord wishes to change a condition (for example, prohibit smoking, or require new fees), they must first discuss the change with you. If you agree, both parties should sign a lease amendment in writing.

If you agree to a change, ask for a formal amendment that is dated and signed by both parties and clearly states the new terms. Keep a copy for your records and ask the landlord to provide you with their signed version as well.

Who Regulates Lease Changes in Saskatchewan?

All residential tenancies in Saskatchewan are governed by the Residential Tenancies Act, 2006 [1]. Disputes and questions about changes to leases are handled by the Office of Residential Tenancies (ORT).

When Can a Landlord Change Lease Rules?

Your landlord cannot unilaterally change your lease rules partway through your tenancy. However, some exceptions and processes apply:

  • After Lease Expiry: When your fixed-term lease ends, the landlord can propose new terms for the renewal. You can choose to accept, negotiate, or move out.
  • By Mutual Agreement: Both parties can agree in writing to modify or add rules at any time.
  • For Periodic Tenancies: Landlords may provide written notice (typically 30 days) to amend certain rules, unless otherwise prohibited by law.

If you receive notice of a change you don’t agree with, you are not required to accept it unless provincial law provides otherwise. Unauthorized or improper changes are not enforceable.

Rent Increases and Other Key Lease Conditions

Changes to the amount of rent follow specific rules. Landlords must provide a minimum of twelve weeks’ written notice for rent increases in most cases. For more details, see Understanding Rent Increases: What Tenants Need to Know.

Unauthorized or mis-timed changes are not enforceable. If you’re unsure, contact the Office of Residential Tenancies for guidance and keep all notices and responses in writing.

Required Forms and Official Process

In Saskatchewan, there is no standard government-issued "lease change" form. However, any amendment should be in writing, dated, and signed by both tenant and landlord. For rent increases, landlords must use the "Notice of Rent Increase (Form 5)" for periodic tenancies.

  • Form Name: Notice of Rent Increase (Form 5)
    When to Use: If your landlord wants to raise the rent, they must provide this written notice.
    How to Use: Your landlord fills out and gives you this form at least 12 weeks before the increase takes effect. Download the Notice of Rent Increase (Form 5) here.

If you disagree with a proposed change, you can apply to the ORT for a hearing or to resolve the dispute. The ORT's application forms and guides are found here.

What Should Tenants Do If a Landlord Tries to Change Lease Rules Improperly?

  • Politely inform your landlord that changes require mutual agreement or proper notice.
  • Keep records: Save any communication regarding the proposed changes.
  • Seek help: Contact the Office of Residential Tenancies or a tenant support service if you feel your rights are violated.
If you’re not sure about a change your landlord wants to make, don't sign anything until you fully understand your rights.
