Quick answer
Adverse possession is the rule that lets a person who occupies land as if they own it, openly and without a break, for at least 10 years, end the true owner’s right to take the land back. In Ontario the 10-year period comes from the Real Property Limitations Act. In Toronto and the GTA it is hard to use: the Land Titles Act says that no title to land registered under the Land Titles system can be gained by length of possession.
Whether a claim is even possible depends on how the land is registered, and claims turn on detailed facts. Check the parcel register and speak with a lawyer before you rely on a claim, or before you worry about one.
Neighbours often fence, garden or park on a strip that is not theirs for years without noticing. When a survey, a sale or a renovation brings the problem to light, one question comes up fast: has the person using the strip gained a right to it? This article explains the rule, where it stops working, and what to do. For the wider picture, see our article on boundary disputes and encroachments.
What Is Adverse Possession in Ontario?
Under section 4 of the Real Property Limitations Act, a person must bring an action to recover land within ten years of the time their right to do so first arose. When an owner has been dispossessed, the time starts on the date of the dispossession (section 5). When the ten years end, the owner’s right and title to the land is extinguished (section 15). In effect, the owner loses the right to recover the land, and the person who has been in possession can claim to own it. See the Real Property Limitations Act on Ontario.ca.
What Does a Claimant Have to Show?
Ontario’s land registration guidance describes the possession as actual, peaceful, continuous, exclusive, open and adverse to the owner’s title. In plain terms:
- Actual: you really use the land, for example by fencing, gardening or parking on it.
- Open: your use is visible, not hidden.
- Continuous: you use it without a break for the full ten years.
- Exclusive: you treat it as yours and keep others out, including the owner.
- Peaceful: you did not take it by force.
- Adverse: you occupy it against the owner’s title, not with their agreement.
The period can also be restarted. If the person in possession signs a written acknowledgement of the owner’s title and gives it to the owner, the owner’s right is treated as arising on the date of the acknowledgement (section 13). That is one reason to take care with anything you sign about a boundary.
Why Land Titles Land Is Different
Ontario has two land registration systems, Registry and Land Titles. Section 51 of the Land Titles Act says that, despite the Real Property Limitations Act, no title to or interest in land registered under the Act that is adverse to the registered owner can be acquired by length of possession. For a property in Land Titles, the usual claim is barred. See the Land Titles Act on Ontario.ca.
Older parcels that were converted to Land Titles with a qualification, known as Land Titles Conversion Qualified (LTCQ), are treated differently. Ontario’s land registration guide says an LTCQ title remains subject to claims based on possession that existed before the conversion, and that time stops running at conversion, so a claim had to be complete by then. See the Ontario land registration guide on LTCQ titles. The 10-year rule also does not apply to vacant Crown land or to public road allowances and highways (section 16). A title search shows how your parcel is registered.
If You Think You Have Gained Land
- Get a current survey from an Ontario Land Surveyor and a copy of the parcel register.
- Find out how the property is registered: Registry, Land Titles or LTCQ.
- Gather evidence of your use: dated photographs, records of when the fence or driveway was built, and statements from long-time neighbours.
- Do not sign anything that acknowledges the owner’s title without advice, because it can restart the period.
- Speak with a lawyer before you approach the owner or start an application.
A claim recognized on title usually needs more than time. Ontario’s guide describes an application process for possession-based claims on converted parcels that includes declarations of possession and notice to the registered owner and others, and it says that 10 years of possession supports only a possessory title.
If a Neighbour May Be Claiming Your Land
- Do not ignore a fence, driveway or structure on your side of the line. Order a survey.
- Remember the ten-year period in section 4: an owner has to act within it to recover the land.
- Consider a written agreement that records your ownership and the terms of the neighbour’s use. See our article on encroachment agreements.
- Ask a lawyer about your options before you confront your neighbour or remove anything.
Buying or Selling With an Encroachment
A survey and a title search usually show encroachments. A buyer’s lawyer will look for them and will ask how they are being dealt with. Title insurance generally does not cover problems you knew about before you bought, so a known encroachment is worth settling first. See our title insurance guide and our article on title insurance vs a survey.
Frequently Asked Questions
Can you claim land by adverse possession in Toronto?
It is very hard. For land registered under the Land Titles Act, section 51 says possession cannot create title. Some older parcels converted to Land Titles with a qualification may still be open to claims that were complete before the conversion. Check how the parcel is registered.
How long does adverse possession take in Ontario?
The Real Property Limitations Act sets ten years, counted from when the owner’s right to recover the land first arose. The period can be restarted by a signed written acknowledgement of the owner’s title.
Does a fence in the wrong place give my neighbour my land?
Not automatically. A fence is evidence of possession, but a claim must meet the ten-year test, and for Land Titles land the claim is barred. Get a survey and legal advice.
Does the ten-year rule apply to Crown land or road allowances?
No. Section 16 excludes vacant Crown land and public road allowances and highways.
Can an owner stop the clock?
The owner can bring an action to recover the land within the ten years. A signed written acknowledgement of the owner’s title by the person in possession also restarts the period.
