How to Sublet in Montreal: The Rules, Your Rights, and the Traps
Subletting is a huge part of how Montreal actually houses people — students leaving for the summer, interns needing four months, anyone caught between the city's rigid July-to-June lease cycle and real life. But subletting in Quebec has specific rules that both subletters and leaseholders get wrong constantly, and the mistakes can cost you. Here is how to sublet in Montreal properly, whether you're taking a sublet or offering one. (For renting a room the standard way, start with our renting guide.)
If a sublet feels too risky to arrange remotely, a furnished all-inclusive room from Coliville at C$160/week gives you the same flexibility with none of the informal-agreement risk.
Sublease vs. Lease Transfer: Know the Difference
Quebec law distinguishes two things people lump together:
- Sublease (sous-location): you rent the unit temporarily; the original tenant keeps the lease and plans to return. Common for summers and internships.
- Lease transfer (cession de bail): you take over the lease permanently; the original tenant is fully released. Common when someone leaves the city for good.
Which one you're doing changes your rights and obligations. Most short-term arrangements are subleases.
The Golden Rule: Landlord Consent
This is where most sublets go wrong:
- The tenant must notify the landlord in writing of the intent to sublet, including the subletter's name and address.
- The landlord cannot unreasonably refuse. They have 15 days to respond; silence counts as consent.
- The landlord can only charge reasonable expenses related to the sublet — not a fee for permission.
A sublet without the landlord's knowledge is a real risk: if it surfaces, the subletter can be forced out. Always confirm the landlord consented, in writing, before you pay anything.
Your Rights as a Subletter
- You're protected too. A subletter has rights under the Tribunal administratif du logement (TAL), though your relationship is with the tenant, not directly the landlord.
- Security deposits are still illegal. Even in a sublet, no one can demand a damage deposit or last month's rent. Only the current month is collectible in advance. This is the single most common way subletters get scammed.
- The original tenant stays responsible. If you trash the place, the landlord pursues the leaseholder — but the leaseholder will pursue you, so document the condition on day one.
Your Obligations as a Leaseholder Subletting Out
If you're the one leaving for the summer:
- You remain on the hook. If your subletter doesn't pay or causes damage, the landlord comes to you. Choose your subletter carefully.
- Notify the landlord properly — in writing, with the subletter's details.
- Put it in writing with your subletter — names, dates, rent, what's included, condition of the unit. A verbal sublet is an invitation to a dispute.
- You can't overcharge. Charging your subletter more than your own rent to pocket the difference is not permitted.
Step-by-Step: Taking a Sublet
- Verify the listing is real — live video tour, meet the tenant, see the actual unit.
- Confirm landlord consent — ask to see the written notice or approval. No consent, no deal.
- Get the agreement in writing — dates, rent, inclusions, condition photos.
- Never pay a deposit — it's illegal; first month only.
- Pay traceably — e-transfer with a note.
- Document the unit's condition on move-in to protect yourself at move-out.
The Scam Warning (Subletters Are Prime Targets)
Summer sublet season is peak scam season, and remote subletters — interns and students booking from another city — are the target. Watch for:
- "I'm already abroad, I'll mail the keys" — never real
- Payment before a viewing or video tour — walk away
- Deposit demands — illegal, and a red flag
- Prices well below market — the bait

Sublet vs. Co-living for Short Stays
| Sublet | Furnished co-living | |
|---|---|---|
| Term flexibility | Good (if dates align) | Excellent |
| Legal clarity | Depends on paperwork | Clear agreement |
| Furniture | Usually included | Always |
| Utilities | Varies | Included |
| Scam risk | High (informal market) | None |
| Bookable remotely | Risky | Designed for it |
For a four-month internship booked from another city, co-living removes the two biggest sublet risks — informal agreements and remote-booking scams. See our intern housing guide.
FAQ
Can my landlord refuse a sublet in Quebec? Not unreasonably. They have 15 days to respond with a valid reason; silence means consent.
Do I need a written sublease agreement? Legally you can sublet informally, but you always should get it in writing — it's your only protection in a dispute.
Can a subletter be asked for a deposit? No. Security deposits are illegal in Quebec, sublets included. First month's rent only.
Is subletting cheaper than co-living? Sometimes on the sticker, rarely once you price in utilities and the risk. For remote bookers, co-living is usually the safer value.
The Bottom Line
Subletting in Montreal is legitimate and common — but it lives or dies on two things: written landlord consent and a written agreement. Get both, never pay a deposit (it's illegal), and never pay before you've seen the place live. If arranging that remotely feels risky, a furnished all-inclusive room gives you the same flexibility without the informal-market exposure.
