CanadaCan someone claim ownership of my land by living on it for many years (adverse possession)?
No — adverse possession is no longer possible for most private land in Canada, because all provinces abolished it for registered land by the early 2000s. It may still apply in rare cases involving unregistered land or specific provincial exceptions.
What the Law Says
Adverse possession — sometimes called 'squatter's rights' — was historically a way for someone who openly, continuously, and exclusively occupied another person’s land for a long period to gain legal title. But Canadian provinces have abolished this doctrine for nearly all land, especially land under a modern land titles system.
In Canada, land ownership is primarily governed by provincial land registration systems — such as the Land Titles Act in Ontario or the Land Title Act in British Columbia. These systems rely on a 'mirror principle': the register reflects true ownership, and interests not on the register generally cannot override it.
Most provinces eliminated adverse possession for registered land by statute. For example, Ontario’s Land Titles Act (R.S.O. 1990, c. L.5) effectively extinguished claims of adverse possession against land in the land titles system — particularly after the 2000 amendments that removed the ability to acquire title by possession alone.
Even where statutes don’t explicitly say 'adverse possession is abolished', courts interpret the statutory scheme as incompatible with it. As confirmed in Canadian Pacific Ltd. v. Paul, the Limitations Act applies to adverse possession claims — but only where the doctrine remains available at all.
What Courts Have Said
The Supreme Court of Canada has clarified the narrow, diminishing scope of adverse possession in Canada — especially in relation to Crown land, tax sales, and statutory land registration systems.
The Court held that an adverse possession interest acquired before a tax sale did not survive the sale — confirming that statutory processes like tax sales can extinguish possessory claims, reinforcing the priority of registered titles over informal occupation.
The Court ruled that adverse possession cannot run against Aboriginal title or Indian reserve lands — and emphasized that the Limitations Act governs time limits for such claims, but only where the doctrine itself still applies under provincial law.
What to Do
Check your province’s land registration system: If your land is registered under a land titles system (nearly all urban and most rural land), adverse possession claims are almost certainly invalid.
Confirm whether your land is unregistered (rare today): Only then might old common law rules possibly apply — consult a real estate lawyer immediately.
If someone is occupying your land, act promptly: Send a written notice asserting ownership and consider filing a trespass complaint or application for possession in provincial court.
Keep records: Property tax receipts, surveys, leases, and photos help prove continuous ownership and rebut any attempted claim.
Never ignore encroachments: Even small structures (e.g., fences, sheds) crossing your boundary could trigger complex disputes — get a survey and legal advice early.
