Direct answer: no. Under Ontario's Residential Tenancies Act, a tenant only has to leave a unit in a state of "ordinary cleanliness" — professional carpet cleaning isn't a legal requirement, even if a lease says otherwise. But "not required" isn't the same as "not worth it," and most people who book it aren't doing it because a landlord is holding a gun to their head. Here's what that actually looks like on real jobs, one from a tenant's side and one from a landlord's.
For a worked example rather than the rules, our Mississauga City Centre condo case study covers a real move-out clean end to end.
The legal reality, in plain terms
Ontario's Residential Tenancies Act sets the standard at "ordinary cleanliness" — sweeping, wiping down surfaces, taking out the garbage, that kind of thing. It doesn't require professional carpet cleaning specifically, and normal wear on a carpet from years of foot traffic is generally considered the landlord's responsibility, not something a tenant has to fix on the way out. Lease clauses that try to mandate professional cleaning or name a specific company are generally unenforceable at the Landlord and Tenant Board, since they conflict with that standard.
There's an important line to be aware of, though: "ordinary cleanliness" is not the same as "no responsibility at all." The Act also makes a tenant responsible for undue damage caused by their own or a guest's wilful or negligent conduct. Worn-down traffic lanes after a few years are ordinary wear. Deep pet urine saturation, or carpet that's been torn or burned, is a different category, and a landlord can pursue those costs at the Board. So the honest version is: you're not required to hand back a professionally cleaned carpet, but you can still be on the hook if the carpet was actually damaged rather than just used. This is general information, not legal advice for your specific lease or situation — if you're in an actual dispute, that's a conversation for the LTB or a paralegal, not a carpet cleaner's blog post.
Real job: a tenant handing back the keys in Mississauga
A tenant called us around the 20th of the month. They were moving out on the 30th, and booked the cleaning for two days before that. That gave the carpet time to dry, so they could hand the unit back looking close to how it looked when they moved in. It was a straightforward job — about 200 square feet, minimal stains, and the stain treatment was already included in the price. It came to $175. They weren't doing it because anyone forced them to. They just wanted to leave the place looking right.
Real job: a landlord prepping a unit for the next tenant
Different situation, different city: a landlord in Oakville booked us to clean a unit — three rooms, a hallway, and stairs — before a new tenant moved in. The carpet was already in good shape with no stains, so it was a straightforward turnover clean rather than anything requiring extra treatment. Stairs and hallways are priced separately from carpeted rooms on our end, consistent with our general rate card ($69 a small bedroom, $99 a large bedroom or living room, $45 a hallway and $30 a closet). The point of that job wasn't damage control — it was making sure the next tenant walked into a place that actually felt clean, not just technically acceptable.
My honest take: it's their living space. Carpet holds dust and dirt over time, no matter whose legal responsibility it is. Most people want that gone before they move in, or want to leave it that way when they move out. That goes double for anyone with kids, allergies or pets in the home. Nobody's required to care about that. Most people do anyway.
What to know before you book (or decide not to)
- You're not legally required to, in Ontario. "Ordinary cleanliness" is the standard, not a professional deep clean — know that going in, whether you're the tenant or the landlord.
- Actual damage is a different question. Ordinary wear is the landlord's to absorb, but undue damage — deep pet urine, tears, burns — can still land on the tenant. Worth being honest with yourself about which one you're looking at.
- A lease clause demanding it usually isn't enforceable. If you're a tenant being told you have no choice, that claim is worth questioning — though for an actual dispute, talk to someone who handles LTB matters, not just a cleaning company.
- Book a couple of days before keys are due back. That gives the carpet time to dry and the unit time to air out before the walkthrough or the next tenant arrives.
- Stains, if any, usually cost more than a plain clean. Ask upfront whether pre-spray and agitation for existing stains are included in the base price, so there's no surprise at the door.
Tenants want to leave a place looking right and landlords want it ready for the next person. The process is the same either way — our carpet cleaning page covers what a standard visit includes.
