In Quebec, a residential lease almost never simply "ends" on its own. At expiry, it is automatically renewed — the principle of tacit renewal written into the Civil Code. For a plex owner, understanding this mechanism is no legal footnote: it decides whether you can adjust a rent, when you must send your notices, and in which rare cases you can actually refuse to renew a lease. This guide clarifies lease renewal and non-renewal, the exact deadlines, and your rights as a multi-unit owner — without the jargon.
What is automatic (tacit) lease renewal in Quebec?
Tacit renewal is the principle whereby a fixed-term lease is automatically extended on the same terms at expiry, unless a valid notice ends it or modifies its terms. The tenant signs nothing: the right to maintain occupancy belongs to them.
Contrary to a widespread belief, a Quebec residential lease does not lapse because its expiry date has passed. The Civil Code of Quebec provides that at the end of a fixed-term lease, it is renewed by operation of law on the same terms, for an equivalent length not exceeding twelve months. This is tacit renewal: no one signs a new document, and the lease simply keeps living.
The heart of Quebec's logic is the tenant's right to maintain occupancy. As long as the tenant meets their obligations, they may stay in the dwelling for as long as they wish. The landlord holds no mirror-image right to "take back their property" at expiry. For a plex or multi-unit owner on the North Shore, this changes everything: your relationship with a tenant is not a contract you can decline to renew as you please.
The one thing you can do at expiry is propose to modify the terms — most often the rent — through a formal notice. And even then, the tenant keeps the right to contest.

How does the lease modification notice work, and what are the deadlines?
The modification notice lets a landlord change a term of the lease (rent, length) at renewal. It must be written and delivered within a strict window: 3 to 6 months before the end for a lease of 12 months or more, 1 to 2 months for a shorter or indeterminate lease.
If you want to raise the rent or change another term (for example, turning a 12-month lease into a shorter one), you must send the tenant a modification notice. This notice must be in writing and respect strict deadlines set by article 1942 of the Civil Code. Outside these windows, the notice is invalid and the lease renews unchanged.
| Lease type | Deadline for the modification notice | Effect if no notice |
|---|---|---|
| Lease of 12 months or more | 3 to 6 months before the lease ends | Renewed on the same terms, same rent |
| Lease of less than 12 months | 1 to 2 months before the lease ends | Renewed on the same terms |
| Indeterminate-term lease | 1 to 2 months before the intended change | No change without a valid notice |
The notice must clearly state the proposed new term. For a rent increase, you must specify the new amount (or the increase in dollars or percent) and the date it would take effect. The calculation follows the Administrative Housing Tribunal's method, which we break down in our guide to the new 2026 rent calculation method.
A late notice = rent frozen for a year
If you miss the window to send the modification notice, the lease renews automatically on the same terms, same rent. You lose, for that whole cycle, the ability to raise the rent. On a multi-unit plex, a few oversights piling up year after year can seriously erode your net income.
What can the tenant do about a modification notice?
On receiving a rent-increase notice, the tenant has one month to respond. They may accept, refuse and stay, or leave. If they refuse and stay, it is the landlord who must apply to the Administrative Housing Tribunal within the month to have the rent fixed. Without a response within the month, the tenant is deemed to have accepted.
The modification notice is not a unilateral decision: it is a proposal. The tenant who receives it has one month to react, and three options are open to them:
- Accept the modification (or say nothing within the month, which counts as acceptance): the lease renews on the new terms.
- Refuse the increase but stay: the tenant notifies the landlord in writing within the month. The lease then renews, but on the old terms until the rent is fixed.
- Leave the dwelling at the end of the lease: the tenant gives notice that they are not renewing and moves out at expiry.
The crucial point for the landlord: if the tenant refuses the increase but stays, it is not up to them to leave or to back down. It is up to the landlord to apply to the Administrative Housing Tribunal, within the month following the refusal, to have the rent fixed. If the landlord fails to do so within that window, the lease renews at the unchanged rent. Many plex owners overlook this reversal of burden and let their right lapse.
In which cases can a landlord end the lease instead of renewing it?
A landlord can only end a lease in cases set out by law: repossession for themselves or an eligible relative, eviction for subdivision/enlargement/change of use, or termination for a serious reason (non-payment of rent, serious prejudice). Outside these cases, the lease must be renewed.
Because renewal is the rule, ending a lease is the exception. A landlord can only achieve it in specific situations, each with its own notices and deadlines:
- Repossession: the landlord (a natural person) may take back a dwelling to live in it themselves or to house an eligible relative — spouse, child, parent, or another relative of whom they are the main support. The deadlines and conditions are detailed in our guide to setting rent on a first lease and Section F, where lease mechanics are set out for owners.
- Eviction for major work: subdividing the dwelling, substantially enlarging it, or changing its use. Eviction is regulated and entitles the tenant to compensation.
- Termination for a serious reason: non-payment of rent (often three weeks in arrears), repeated late payments, serious prejudice to the building or other occupants. Termination goes through an application to the Administrative Housing Tribunal.
What is not a valid ground: wanting a higher market rent, preferring a "better" tenant, or simply wishing to reclaim the dwelling for no reason recognized by law. Attempting to evict a tenant under a false pretext of repossession exposes the landlord to penalties and damages. Note too that lease assignment lets the tenant transfer their lease — a separate mechanism we cover in lease assignment and Law 31.

The renewal timeline, step by step
For a typical 12-month lease ending on June 30 (the most common date in Quebec), here is the sequence to follow on the landlord's side:
- 6 months before the end (earliest) — You may begin sending your written modification notice with the proposed increase.
- 3 months before the end (latest) — Final deadline to deliver the notice. After it, the lease renews at the unchanged rent.
- 1 month after the notice — The tenant responds: accept, refuse and stay, or leave. Silence counts as acceptance.
- 1 month after a refusal — If the tenant refuses the increase but stays, you have one month to apply to the Administrative Housing Tribunal to have the rent fixed.
- Renewal — The new lease takes effect at expiry, on the terms accepted or fixed by the Tribunal.
The plex owner's good habits
- Always give notice in writing, with proof of receipt
- Respect the 3-to-6-month window for a 12-month-plus lease
- Watch the one-month window to apply to the Tribunal after a refusal
- Document every renewal and every increase applied
What are the common mistakes around lease renewal?
The same missteps recur among multi-unit owners, and they cost dearly in lost income or disputes:
- Believing the lease "ends" at expiry: no, it renews. Sending no notice never frees up the dwelling.
- Giving a verbal notice or an unconfirmed text: without writing and proof of receipt, the notice is fragile and easily set aside by the Tribunal.
- Missing the one-month window to apply to the Tribunal after a refusal: the rent then stays frozen for the year.
- Confusing repossession with a simple non-renewal: you cannot just "not renew"; you must invoke a specific legal ground, with its own notices.
- Letting rents fall behind renewal after renewal: this is the mistake that weighs most on a plex's resale value.
That last point deserves attention if you are thinking of selling. A plex is valued first on its income: leases renewed with below-market rents reduce net operating income and therefore your building's value. A record of rigorous renewals, with increases applied on time, directly supports the price.
