Renting to Students in Waterloo, London & Kingston: Licensing, Leases and Turnover

Every guide to student rentals gives the same advice: put all five students on one joint lease, so each one is liable for the whole rent.

Waterloo's rental licensing by-law says written leases with one tenant per lease.

London says a rental that isn't zoned as a rooming house can't rent to more than three individuals on separate leases.

Read those together and something strange emerges. The advice everyone gives is a licence violation in one city and a zoning problem in the other — and the two cities are 100 kilometres apart. The same five students, the same house, the same rent, and the document one city requires is the one the other restricts.

The lease structure was never your decision. And neither was the calendar. Here's the part that costs the most money: the 12-month lease everyone signs doesn't end. It converts to month-to-month. Pre-lease the house to a September group while your current tenants haven't served notice, and you have two groups and one house.

This guide covers which city decides your document, what Waterloo's new July 1 by-law actually requires, why a licence doesn't survive a sale in London, what a parental guarantor really signs, and why the student year is decided in January. It's a framework and a method, not legal advice — and Waterloo's rules changed two weeks ago, so verify before you rely on any of it.

The Document Isn't Yours to Choose

Start with the advice everyone gives, because it isn't wrong — it's just not always available.

One joint lease, joint and several liability. Western University's off-campus housing service puts the mechanics plainly: if two or more tenants are on the same lease, each is responsible to the landlord for the whole rent regardless of the arrangement made among them to share it. If one leaves, the others cover that share. A landlord can pursue any one of them, or all of them, for the full amount. That's the appeal, and it's real.

Then read Waterloo's by-law. Class C rental units: "there shall be written leases with only one (1) Tenant per lease, unless the Tenant is under the age of sixteen (16) years," in which case a parent or guardian may sign on their behalf. Individual leases aren't a strategy in Waterloo. They're a licence condition.

Then read London's. A rental accommodation that isn't zoned as a rooming house cannot rent to more than three individuals on separate leases. The thing Waterloo requires, London restricts past three.

Why this is different from "rules vary by city"

Rules varying by degree is ordinary. One city charges a bigger fee, another inspects more often, a third wants more paperwork. You budget for it and move on.

These vary in direction. The compliant document in Waterloo is the non-compliant one in London — and nothing about the house, the students, the rent or the tenancy has changed. Only the address.

If you've read our guide to multi-tenant house rules, you already know half of this. That piece taught that leasing room-by-room can make a house a multi-tenant house or rooming house — the lease structure is a definition, not just a revenue model. London says exactly that in local form. But Waterloo inverts it: the licence compels the room lease. So the careful landlord who read that guide, avoided room leases and put everyone on one document is non-compliant in Waterloo. Same lesson, opposite instruction.

None of this is about extracting more per room. It's about which document is lawful where your house happens to sit. Whatever structure you land on, the Ontario Standard Lease is required either way.

Licensing: The Student-Specific Slice

Waterloo's rules are two weeks old. The City's own words: "New rental licensing requirements start July 1, 2026." The by-law is 2025-044. If you last checked your obligations in June, you checked the old rules.

And there's a wrinkle worth internalising: the City's published version of the by-law carries a caveat that it "is a consolidated digital version of the official legal document. It is not an exact reproduction and is for information purposes only." The page you can read is not the law. Go to the official document, or call 519-747-8785.

What Waterloo's Class C actually says

Beyond the one-tenant-per-lease condition, three things catch people:

• Your application defines your bedrooms. No room in a rental unit may be used as a bedroom except where a bedroom has been depicted on the licence application submitted to the City. A room that looks like a bedroom, is furnished like a bedroom and has a tenant sleeping in it is not a bedroom for licensing purposes unless you drew it as one.
• No water distribution to or from a bedroom — an anti-illegal-unit provision that catches a lot of older houses with sinks in the rooms.
• Compliance with all law, including the Ontario Human Rights Code, is written into the schedule. Your screening practices are a licensing matter, not just a good-practice matter.

The refusal grounds are broader than most landlords expect. The Director may deny a licence or renewal where the property is subject to orders under the Property Standards By-law, the Building Code Act, the Fire Protection and Prevention Act or the Ontario Fire Code, or the Medical Officer of Health; where the property doesn't comply with the Zoning By-law; where the owner is indebted to the City by way of fines, penalties, judgments or outstanding property taxes; or on certain convictions in the past five years. And "Applicant" includes any director, officer, partner or principal — a corporate structure doesn't reset the slate.

London: the zoning officer reads it before licensing does

London's Residential Rental Unit Licensing (RRUL) by-law, CP-19, states its purpose as protecting health and safety and maintaining the amenity, character, and stability of residential areas. The process reflects that.

Zoning is screened first: "Prior to a new rental licence application being accepted by our office, a Zoning Officer will review your application to ensure it complies with the Zoning By-law." Note the sequencing — that's before acceptance, not before approval. A zoning problem isn't a late-stage surprise; it's a first-stage gate. Property standards and fire inspections are mandatory for every new licence.

The process is also refreshingly analogue: you apply by email to [email protected], "Online application submission is not yet available," and incomplete packages will not be processed — everything and payment together, one package. Owner-occupied and renting to more than three tenants? A Zoning By-law Amendment and/or a Lodging House Business Licence may be required. And if you also run short-term stays, that's a separate regime — a property can need both an RRUL and a short-term accommodation licence.

One more sentence from CP-19 deserves its own line, because it echoes something Toronto says about pre-approved plans. Issuing a licence "is not intended and shall not be construed as permission or consent by the City for the Licensee to contravene or fail to observe or comply with any law of Canada, Ontario or any by-law of the City." The City licensed you. It didn't clear you. A licence is not a compliance certificate, and holding one is not a defence to anything else.

Kingston: we're not going to pretend

Kingston is in the title of this article, so here is an honest accounting. We could not confirm an authoritative source for Kingston's rental licensing requirements while researching this piece, so we're not asserting any. Not "Kingston is similar." Not "Kingston likely requires." Nothing.

What is confirmed: in February 2026, Kingston City Council approved a motion to develop a formal Student Housing Strategy, focused on densification, expanding Queen's University student housing supply, and encouraging private purpose-built student housing along major corridors. If you own near Queen's, confirm your licensing obligations with the City of Kingston directly before you rely on anything — including this page.

A guide that fills a gap with confidence is the guide that gets you fined. Our municipal licensing tracker is the place to start on the wider picture, and if you're weighing where to buy in the first place, the student rental neighbourhood guide covers the three cities.

The Two Traps Nobody Warns You About

Trap one: the guarantor guarantees everyone

Here is Western's off-campus service, stating it as plainly as it can be stated: "If you are on a joint lease with your roommates, the guarantor(s) are liable for any tenant, not just the student they are guaranteeing."

A parent signing for their daughter is standing behind her four housemates too. That follows directly from joint and several liability — each tenant owes the whole rent, and a guarantor stands behind that obligation, not behind one person's share of it.

Most parents don't know this. Tell them before they sign, and put it in language a person can read without a lawyer. Not because it's a gotcha to be sprung later — the opposite. A guarantee that somebody didn't understand when they signed it is the one you end up arguing about at the Landlord and Tenant Board. A guarantor who understood exactly what they were signing is the one who pays without a fight.

Trap two: the lease that doesn't end

A 12-month fixed term converts to a month-to-month tenancy when the term runs out. It does not self-terminate in August. A landlord cannot require a tenant to leave just because the term is up — every fixed-term lease in Ontario converts, and student leases are not an exception.

Now put that next to the student calendar. You've pre-leased the house to an incoming group for September 1. Your current tenants never served an N9. Their term converted, they're still tenants, and they have security of tenure. You now have two groups and one house — one holding a signed lease and nowhere to live, one holding the legal right to stay.

The entire student turnover cycle assumes an ending the Residential Tenancies Act doesn't supply.

The fix is procedural and completely unglamorous. Know which tenants have given notice before you sign the next group. Get the N9 in writing. If the outgoing group wants to leave early or by agreement, an N11 is the cooperative route, and the termination date calculator will get the dates right. The calendar doesn't create the vacancy — notice does.

And the sublet question is coming whether you plan for it or not. Co-op placements and summer terms mean students want to sublet. Under the RTA a tenant can assign with your consent, which cannot be unreasonably withheld. A roommate who isn't on the lease becomes a sub-tenant — and the main tenants are liable for the sub-tenant's actions. Occupancy standards still apply regardless.

The Market Turned, and the Year Is Decided in January

The demand side of student housing has inverted, and it's policy-driven rather than cyclical.

The 2026 national study permit cap was reduced to 408,000 permits — down 7% year over year and 16% below 2024 levels. Ontario received 104,780 Provincial Attestation Letters and a maximum of 70,074 permits, a 42% decrease from 2025 and the third straight annual cut. Three consecutive years of contraction is not a blip; it's a new baseline.

What it looks like on the ground is the interesting part: it showed up closest to campus first. CMHC reports that Kitchener–Cambridge–Waterloo held elevated vacancy through 2025, with the strongest increases concentrated around the University of Waterloo and Wilfrid Laurier — the submarkets that were tightest are the ones that loosened most. Industry tracking places the region between 2.5% and 4.0%. In London, CMHC shows purpose-built vacancy rising steadily since its 2023 low of 1.4%, with 2026 estimates of 3.5–4.0% — the highest since 2010 — and buildings near Western now offering one to three months of free rent on new leases.

The honest limit: there is no CMHC series for a room in a student house. CMHC doesn't survey them. The figures in circulation — London rooms at $700–$1,050, purpose-built suites on Richmond Street at $1,080–$1,500 per bed, Kingston shared rooms at $700–$1,300 before utilities — are indicative, not authoritative. Price from local comparables, not from a guide's estimate. Ours included.

Why this matters mechanically: a room in a student house is a secondary-market unit. It resets to market on turnover, so it tracks asking rents — which are softening in exactly the submarkets nearest the campuses. That's not a reason to panic. It's a reason to lease early, price honestly, and keep good tenants when you have them. For the wider picture, see vacancy rates by Ontario city.

What's coming: Kingston's Student Housing Strategy is in development after February's Council motion. Waterloo's by-law just changed. This section has a shelf life, and the by-law is the only thing that governs.

Key Takeaways: Read the By-law Before You Draft the Lease

1. Find out what your city requires of the lease itself — before you draft one. Waterloo requires one tenant per lease. London restricts more than three individuals on separate leases without rooming-house zoning.
2. If you own in Waterloo, re-read the by-law. It changed July 1, 2026, and the City's published version isn't the official document.
3. Explain the guarantee to the guarantor. On a joint lease they're liable for every tenant, not just their own child.
4. Never sign the next group until the current group has given notice in writing — an N9, or an N11 by agreement. The lease does not end by itself.
5. Buying a licensed student rental in London? Ask about the licence. It isn't transferable, the seller surrenders it within 72 hours, and you apply as a new applicant.
6. Market in January, sign by March. The September cycle is decided in winter — and the market has loosened.
7. Verify every municipal claim with the municipality. A widely-read guide currently calls a Waterloo licence condition an RTA requirement.

Quick win: check whether your property is licensed and what class it holds. London publishes a public property search for exactly this. Long game: the licensed, inspected, correctly-documented student house is the one that survives a change of ownership, a change of by-law, and a change in demand.

The Bottom Line

The lease structure isn't yours to choose. Waterloo requires the document London restricts, and the advice you'll find on almost every student-rental page is a problem in one of those two cities. A licence in London doesn't survive the sale of the house and doesn't certify that you're compliant. A parental guarantor on a joint lease is standing behind the whole group. And the 12-month lease that "ends" in August doesn't end — which is how a careful landlord ends up with two groups and one house.

That's the pattern this series keeps finding, and it holds here: the rule you can find is rarely the rule that binds.

Meanwhile the demand that made student rentals feel automatic has thinned. Three straight years of permit cuts, and the softest submarkets are the ones nearest campus. None of that is a reason to avoid renting to students. They're tenants like any others — same standard lease, same rights, same last month's rent and no more. It's a reason to read your city's by-law before you draft your document, and to serve notice before you sign the next group. A framework and a method, not legal advice.

Frequently Asked Questions

Can I put all my student tenants on one lease in Ontario?

It depends on your city, which surprises most landlords. There's no provincial rule requiring either structure — the RTA doesn't mandate joint leases or individual leases. But municipal licensing can, and two of Ontario's biggest university towns land in opposite places. Waterloo's rental licensing by-law requires written leases with only one tenant per lease (unless the tenant is under 16, in which case a parent or guardian may sign). London restricts it from the other side: a rental not zoned as a rooming house cannot rent to more than three individuals on separate leases. So the same five-student house needs individual leases in Waterloo and would need rooming-house zoning for that structure in London. Before you draft anything, confirm what your municipality requires — and be careful with online guides, because at least one widely-read page currently describes Waterloo's licence condition as an RTA requirement. It isn't. That distinction matters: a provincial rule applies everywhere; a licence condition applies to one city.

Does a rental licence transfer when I sell a student rental in London?

No — and this catches buyers. London's by-law is explicit: no licence may be sold, purchased, leased, mortgaged, charged, assigned, pledged or transferred. The licence belongs to the City, is valid only for the named person and the named rental unit, and a separate licence is required for each rental property. On a change of ownership the licensee must notify the Licence Manager and surrender the licence within seventy-two hours. So buying a licensed student house does not make you licensed — you apply as a new applicant, and your application goes through zoning review, property standards and fire inspection like anyone else's. Worth noting how this differs from other municipal instruments: a vacant home tax lien and a development charge deferral agreement both attach to the property and follow it to the buyer. This one attaches to the person and doesn't. The lesson is to check which way each instrument runs rather than assume.

Is a parent guarantor liable for all the roommates?

On a joint lease, yes. As Western's off-campus housing service puts it: if the students are on a joint lease, the guarantors are liable for any tenant, not just the student they are guaranteeing. That follows from how joint and several liability works — each tenant is responsible to the landlord for the whole rent regardless of how they've split it among themselves, and a guarantor stands behind that obligation. Most parents signing a student lease do not know this, and the fair thing to do is tell them before they sign. If your city requires individual leases — as Waterloo's licensing by-law does — the guarantee follows the individual lease instead, which changes the arrangement considerably. Either way, put the structure in front of the guarantor in plain language. A guarantee that somebody didn't understand when they signed it is the one you end up arguing about at the Landlord and Tenant Board.

Does a 12-month student lease end automatically in August?

No, and this is the most expensive misunderstanding in student rentals. In Ontario a fixed-term lease converts to a month-to-month tenancy when the term ends. Nothing terminates on its own, and a landlord cannot require a tenant to move out just because the term is up. So the September turnover cycle everyone plans around assumes an ending the Residential Tenancies Act doesn't supply. If you pre-lease the house to an incoming group for September 1 and your current tenants never served an N9, you have two groups with claims on one house — one holding a signed lease, one holding security of tenure. The fix is procedural: get notice in writing before you sign anybody new. An N9 from the tenants, or an N11 if you're ending it by mutual agreement. Never let the calendar do work that only notice can do.

When should I start marketing a student rental?

Far earlier than feels natural. Leases for the September–August cycle are typically signed January to April of the preceding year, and serious groups begin looking as early as November. The practical rule: market in January, aim to have leases signed by March. Co-op students working on a May 1 cycle follow a similar timeline with a smaller pool. What's changed for 2026 is the demand side: Ontario's study permit allocation is down roughly 42% from 2025 — the third consecutive annual cut — and CMHC reports that vacancy increases in Waterloo Region have been concentrated around the University of Waterloo and Laurier, with London's vacancy at its highest level since 2010 and buildings near Western offering months of free rent. That's not a reason to avoid the market; it's a reason to start early, price against real local comparables rather than a guide's estimate, and keep good tenants when you have them.
