Canada's One-Rental Rule: What London, Ontario Changed on 1 October

A rule that follows the owner instead of the address is easy to misread. The count you keep has to change with it.

Last updated: October 5, 2026

A rule that counts owners instead of addresses is easy to misread. A per-owner short-let rule lets each owner hold one permit, no matter how many units they own. A per-address cap does the opposite, limiting how many permits a single building or block can carry. The two produce different answers for the same host, and the difference decides how you count. Here's what to check before you list again.

Key Takeaways

• A per-owner rule counts people, not properties. Each owner usually gets one permit, whatever the number of units they hold.
• A per-address cap counts locations. It limits permits by building or block, so the same owner can hold several.
• Existing permits often run to their own end. A permit already issued usually keeps going until it lapses or a renewal is decided.
• Joint ownership complicates the count. A property held by two people may or may not count as one owner, and cities read that differently.
• Check the local counting rule first. How your city defines an owner matters more than how many units you hold.

What a per-owner rule counts

A per-owner rule asks a simple question: how many permits does this person hold? The unit of measure isn't the building or the unit. It's the owner. One owner, one permit is the shape of it. A host with three apartments can't operate all three the same way.

That's a shift from what many hosts expect. Most short-let rules they've met count addresses. This one follows the person, so it travels with you. Sell one unit and buy another, and your permit may move with you rather than multiply.

The count also forces a definition. Who is the owner? A single name, a couple, a company, a trust, each can be read differently. A city that counts a married couple as one owner produces a different answer than one that counts them as two.

So the first thing to settle is how your city counts. Not how many units you have. You can own five and be limited to one permit, or own one and hold it in a name that changes the answer.

That ambiguity is the point of friction for most hosts. They focus on their portfolio and forget that the rule is reading a name, not a spreadsheet of units. Fix the name question first. The rest of the arithmetic follows from it.

How it differs from a per-address cap

A per-address cap works the other way. It sets a limit at the location. This building may carry this many short-let permits, or this block may carry that many. The count is spatial. It says nothing about who owns the units.

Under a per-address cap, one owner can hold several permits if they sit at different addresses, and several owners can compete for permits at the same address. Under a per-owner rule, the same owner can't spread across addresses at all. The same portfolio produces two different outcomes.

Picture two owners, each with two units in the same building. If the rule counts addresses, the building's cap applies to both of them together, and the answer depends on the building. If the rule counts owners, each owner is measured alone, and the answer depends on the person.

This is why the same headline can mean different things in different places. A rule described as a cap on short lets tells you nothing until you know what it's counting. Read the counting unit before you read the number.

One more difference is how a rule adjusts over time. A per-address cap moves when the building changes, because the building is the thing being counted. A per-owner rule moves when your ownership changes, because you're the thing being counted. A sale, a purchase or a name change can shift your position under one rule while leaving it untouched under the other.

The two rules also fail differently. Miss a per-address cap and you may have one unit too many at a single building. Miss a per-owner rule and you may have a whole second property running without a valid permit. The second kind of gap tends to surface at renewal, and quietly.

What existing permits usually do

A permit that's already been issued usually runs until it lapses or until a renewal is decided. That's the common shape of a transition, and it's why established hosts often keep operating while new applicants wait. The transition is usually written to soften the change, not to erase it.

But a per-owner rule can still reach an operator who holds permits at more than one address. If the new counting treats them as one owner, the second permit may not survive its next renewal. The transition doesn't always consolidate at once, so the timing matters.

The practical question is whether your permits are tied to a person or to a property. A permit issued to a named individual behaves differently from one attached to the unit. Check which yours is, because a renewal is when the difference shows up.

Don't assume a letter you received years ago still describes today's position. Rules get amended, and the authority's current guidance is the version that binds you. Read it fresh, and read it from the source rather than from a summary.

If you hold permits in more than one name, that structure is what the rule reads. A single operator with units split across two companies may look like two owners to one city and one owner to another. The paperwork you filed becomes the paperwork they count.

What to check before you list again

Before you list again, four checks cover most of the ground. How does your city define an owner? Is your permit tied to the person or the property? What happens at renewal? And does a pending application fall under the old count or the new one? Answer those, and you know where you stand.

Getting your data in one place makes the checks faster. LOCALSBNB can import your listing data from Airbnb, including titles, photos, base capacity and the calendar structure, so your unit records start complete rather than half-built. A calendar that shows the source rate and source status for each direct channel you connect then tells you what's live where. localsbnb.com keeps that material together, so a rule change becomes a filing task, not a rebuild.

Then write down your owner structure. If your units sit in more than one name, map which permit belongs to which. A per-owner rule turns that map into the single most useful document you hold, because it answers the first question any authority will ask.

Finally, set a date to review it. Ownership changes, and so do the rules that read it. A yearly pass through the map, against the authority's current guidance, keeps a small question from becoming a large one.

None of this requires guessing. It requires the four answers, written down and dated. A host who can produce them on demand is a host no review surprises.

FAQ

Does a one-per-owner rule apply across the whole country?

No. A per-owner rule is a local choice, not a national one. What one city counts, another may not. Treat any specific rule as local, and check the current position with the authority that issues your permit.

I own two units. Can I operate both?

It depends on how your city counts owners and where your permits sit. A per-owner rule may limit you to one. A per-address cap may not. Confirm your own structure with the local authority before you list.

What happens to a permit I already hold?

An existing permit usually keeps running until it lapses or a renewal is decided. Read how your permit is tied, to a person or to a property, because that distinction often decides what happens at renewal.

A per-owner rule rewards one habit: knowing exactly what you own and in whose name. Map your permits, keep the records current, and check the local count before you list. When you want your listing and channel data in one place, begin with localsbnb.com and keep it that way.
