Squatters' rights in Ontario: how long, and why most land is now out of reach
Ten years under the Real Property Limitations Act, but section 51 of the Land Titles Act stops the clock once land is in the Land Titles system. A claim on that land only survives if the full ten years ran before the land was registered.

Ontario runs two land registration systems side by side. Under the older Registry system, the Real Property Limitations Act, section 4, gives an owner ten years to recover land from someone in possession, and once that time has run the owner's title is extinguished. Courts ask for possession that is open, notorious, peaceful, adverse, exclusive, actual and continuous for the whole ten years.
Section 51 of the Land Titles Act changes that for registered land. It says that no title adverse to the registered owner is acquired "by any length of possession or by prescription" once land is registered under the Act. Most Ontario parcels have been converted from Registry to Land Titles, so for most properties a squatter who moved in after conversion can never reach ownership, however long they stay.
The exception is a claim that had already matured. If someone can show ten qualifying years that were complete before the parcel entered Land Titles, that claim can survive the conversion. This is why adverse possession disputes in Ontario today are mostly about old fence lines and driveways between neighbours rather than strangers moving into a house.

How it unfolds
From the day someone moves in to the day a claim is possible
The same three stages in most places. The exact rule, and whether the last stage exists at all, is on each place's own page.
- Day oneMoving inCaught in the act, it is usually a matter for the police: a trespass, not a tenancy.
- Weeks to yearsSettled inOnce someone lives there, removing them usually takes a court order, the same route as for a tenant.
- After 10 years, before Land TitlesA claim becomes possibleOnly if every test held, without a break, for the whole period. Where the law allows no such claim, this stage never comes.
Not yours to do, once they have moved inChanging the locks, cutting the water or power, or removing belongings yourself. It is illegal in every US state and most places on these pages forbid it too. Each page says how removal works there.
Before it is ever a court case
The record a court asks for, kept as you go
Wherever your property stands, removing an occupant usually comes down to showing who had the right to be there, and since when. Dardaris files every lease, message and document for a building by date, so that record already exists on the day you need it.
- Every lease, with who signed it and when
- Every message with a tenant, on the thread it was sent in
- Every document, filed against the building it concerns
Frequently asked questions
How long are squatters' rights in Ontario?
Ten years of qualifying possession under section 4 of the Real Property Limitations Act. On Land Titles land, section 51 of the Land Titles Act means those ten years must have been complete before the land was registered in that system.
Does adverse possession still exist in Ontario?
Only in a narrow form. It remains available against land still in the Registry system and for claims that matured before a parcel was converted to Land Titles. Against land already in Land Titles, possession that begins after registration does not lead to title.
How does an Ontario owner remove a squatter?
Someone on premises without permission can be told to leave and, if they stay, commits an offence under the Trespass to Property Act, which the police enforce. If the occupant may be a tenant, for example because rent was accepted, the Residential Tenancies Act applies instead, and changing the locks without a Landlord and Tenant Board order is an illegal lockout.
Are squatters' rights in Canada the same in every province?
No. Adverse possession is provincial and territorial law, so squatters rights in Canada vary: Ontario keeps a narrow ten-year rule, Alberta abolished it in 2022, British Columbia, Saskatchewan and the Yukon bar it against registered land, and Quebec uses acquisitive prescription under its Civil Code.
