Lease Addendum — Quebec (Avenant au bail)

Yes, but with important limitations. Under the CCQ and TAL rules, any additional conditions added to a lease must not reduce the tenant's rights below the minimum standards established by law. For residential leases, the standard TAL lease form (Form F) already includes the main terms, and addendums must be consistent with the CCQ and the rules of the TAL. Landlords may add conditions about pets, smoking, parking, storage, and similar matters, provided these conditions do not discriminate against tenants under the Quebec Charter of Human Rights and Freedoms. Conditions that would transfer landlord maintenance obligations to tenants, or that would require tenants to waive rights under the CCQ, are generally unenforceable.

A Quebec Lease Addendum does not legally require a lawyer, and landlords and tenants may draft and execute it independently. The Civil Code of Quebec (CCQ), art. 1851-2000 does not mandate legal representation for residential lease addendums. However, independent legal advice from a qualified Quebec lawyer is recommended where the addendum contains complex clauses about renovations, sublet rights, or modifications to the standard Tribunal administratif du logement (TAL) lease form. The TAL itself provides free information services to landlords and tenants in Quebec. The Superior Court of Quebec has jurisdiction over disputes that cannot be resolved by the TAL. Professional review is advisable where the addendum may conflict with mandatory provisions of the CCQ that cannot be waived by agreement.

Under Quebec civil law and the Tribunal administratif du logement (TAL) rules, a landlord may add conditions about pets, smoking, parking, storage, appliance maintenance responsibilities, and quiet hours. However, the Consumer Protection Act (CQLR c P-40.1) and the CCQ prohibit conditions that reduce the tenant's statutory rights below the minimum standards established by law. The Quebec Charter of Human Rights and Freedoms prohibits addendum conditions that discriminate based on grounds such as family status, disability, or ethnic origin. Conditions transferring the landlord's statutory maintenance obligations to the tenant under CCQ art. 1910 are generally unenforceable. Any addendum condition that conflicts with the CCQ's mandatory residential tenancy provisions is automatically void under CCQ art. 1893. Forms-legal.com recommends using the standard TAL addendum form as a base.

A lease addendum is a supplementary document attached to and incorporated into the existing lease that adds new conditions not originally covered, such as pet permissions, parking arrangements, or storage access. A lease amendment modifies an existing term already contained in the lease — for example, changing the monthly rent amount or extending the lease term. Both require the signature of all parties (landlord and all tenants) to be effective under Quebec civil law. Under CCQ art. 1895, any modification to a residential lease that would reduce the tenant's rights below the minimum prescribed by law is null and void. For residential leases under the Tribunal administratif du logement (TAL) regime, modifications to rent amount are governed by specific notice requirements under CCQ arts. 1941-1946 rather than a simple amendment.

Yes. A tenant in Quebec is not required to sign a lease addendum unless they agree to the proposed additional conditions. Under CCQ art. 1895, a landlord cannot unilaterally add conditions to a residential lease after it has been signed. If a landlord attempts to impose new conditions at the start of a new lease term, the tenant has the right to refuse the changes and continue the lease on the same terms under CCQ art. 1941. The Tribunal administratif du logement (TAL) provides a dispute resolution mechanism when landlord and tenant cannot agree on proposed changes. Tenants should be aware that signing an addendum containing clauses that waive statutory rights is generally ineffective under Quebec law. The Commission des droits de la personne et des droits de la jeunesse (CDPDJ) can investigate discriminatory addendum conditions.
