How Many People Can Legally Live in One Bedroom? Ontario Occupancy Standards for Landlords

There is no province-wide number. Your municipality’s property-standards by-law sets the limit; the Residential Tenancies Act only supplies the process to act on it.

I am Arthur Zhao, a broker who has worked the GTA full-time for 12 years, and this is one of the questions landlords ask me most often before they rent out a basement, add a roommate, or list a house they suspect is over-full: how many people are actually allowed to live here?

The honest answer surprises people. Ontario has no single legal occupancy number. The rule you are looking for lives in two different places at once — a municipal by-law that supplies the number, and a provincial statute that supplies the process — and confusing the two is where landlords get themselves into trouble. Here is how the two systems actually fit together, using Toronto as the worked example.

Two legal systems, not one

Most people assume there is a tidy rule somewhere — two per bedroom, say, or a fixed cap per unit. There is not. What actually governs how many people may occupy a home comes from two separate machines that most landlords never realise are separate.

The first is the municipal property-standards by-law. Under the Building Code Act, 1992, each municipality passes its own occupancy standards, and those by-laws are where the real numbers — minimum floor area per person, minimum room sizes — actually live.

The second is the Residential Tenancies Act, 2006 (RTA), which governs the relationship between landlord and tenant. Crucially, the RTA does not invent an occupancy number of its own. It points back at the municipal standard and gives a landlord a procedure to end a tenancy when that standard is breached. So one system tells you the number; the other tells you what you are allowed to do about it.

What Toronto’s by-law actually says

Toronto’s occupancy rules sit in s.629-25 of Chapter 629 of the Municipal Code (Property Standards). It is worth reading the figures precisely, because they are easy to mix up.

General density of a habitable room. The number of people living in a habitable room may not exceed one person for every 9 m² of habitable floor area. This is a general density ceiling for the room — do not apply it directly to a bedroom headcount.

Rooms used for sleeping — this is the bedroom answer. A room used for sleeping by only one person must have a floor area of at least 6 m², with a minimum dimension of 2 m on one side. A room used for sleeping by two or more people must provide at least 4 m² of floor area for each person using it. So the practical question — how many people can share this bedroom — lands on this last rule: take the usable floor area and divide by four.

The ceiling-height caveat. A habitable room must be at least 1.95 m high over at least half its floor area. And any floor area sitting under a ceiling lower than 1.4 m is simply not counted toward a sleeping room’s required area — it is not prohibited, it just does not help you meet the minimum. That detail matters in sloped-ceiling attics and finished basements, where the floor looks big but the countable area is smaller than it appears.

By-law vs. RTA: who supplies what

How the RTA ends a tenancy for “too many persons” — s.67

Section 67 of the RTA is the provincial half of the machine. Read it closely, because it is built to give the tenant a real chance to fix the problem before anyone loses a home.

The ground (s.67(1)). A landlord may give notice of termination if the number of persons occupying the unit, on a continuing basis, results in a contravention of health, safety or housing standards required by law. Two things do the heavy lifting here: it must be ongoing occupancy, not a weekend full of guests, and the breach is measured against those external standards — in practice, the municipal by-law above.

The notice (s.67(2)). The notice must set a termination date no earlier than the 20th day after it is given, set out the details of the grounds, and require the tenant — within seven days — to reduce the number of people occupying the unit so that it complies.

The escape hatch (s.67(3)). The notice is void if, within those seven days, the tenant sufficiently reduces the number of occupants. In other words, s.67 is not designed to evict — it is designed to get the unit back within the standard. If the tenant complies, the tenancy simply continues.

On the LTB’s published forms, this kind of notice is served on Form N5 — Notice to End your Tenancy for Interfering with Others, Damage or Overcrowding. Note the form’s own title spans three separate grounds; overcrowding is only one of them, and the s.67 procedure above is the part that applies here.

Children are not overcrowding: the s.83(3)(e) guardrail

There is one protection every landlord should know before they even think about acting on headcount. Under s.83(3)(e) of the RTA, the Board shall not issue an eviction order where the reason for the application is that the unit is occupied by children and the occupation by the children does not constitute overcrowding.

Read plainly: a growing family, a new baby, or children simply living in the home can never on its own be the basis for eviction. The only question the Board will entertain is whether there is actual overcrowding measured against the standard — and if there is not, the presence of children is legally irrelevant. A landlord who tries to use a family’s children as a pretext is not just on shaky ground; they are pointed directly at a rule written to stop exactly that.

Before you rent by the room or by the head

If you are setting occupancy limits, renting a basement, or listing by the room, a few practical rules keep you compliant and out of a losing hearing.

Check your own municipality — do not borrow Toronto’s numbers. Property-standards by-laws are municipal. The 9 m² / 6 m² / 4 m² figures above are Toronto’s; Mississauga, Markham, Vaughan, Brampton and every other city set their own under the Building Code Act, 1992. Pull your city’s property-standards or occupancy by-law before you advertise a number.

Measure sleeping-room area, not bedroom count. Whether a room can hold one, two or three people is a floor-area calculation, not a label on a floor plan. Discount the low-ceiling corners — under 1.4 m does not count — and do the math per person.

Put the occupancy limit in the lease honestly. A reasonable occupancy term grounded in the actual by-law is far stronger than an arbitrary cap, and it sets expectations before anyone moves in.

Never self-help. A s.67 notice does not remove anyone by itself, and you cannot change the locks, remove belongings, or pressure a tenant out. If the tenant does not reduce occupancy within seven days, the only lawful next step is an application to the LTB. For an actual eviction, get the LTB’s guidance or a licensed paralegal or lawyer — the process is unforgiving of shortcuts.
