A Lien Search is one of the most important steps in any Ontario real estate transaction, lending decision, or due diligence review. Hidden mortgages, construction liens, writs of execution, and tax arrears can quietly attach themselves to a property's title — and if they aren't cleared before closing, they can transfer to the new owner. Before you buy a home in Toronto, lend money against a rental in Ottawa, close on a condo in Mississauga, or accept a property as collateral anywhere in the province, a proper Lien Search Ontario protects your investment. LandTitleSearch.ca pulls encumbrance information directly from Ontario's land registration system, so you get court-ready results in minutes.
An Ontario Lien Search is the process of reviewing the official land title register for a given property to identify every legal claim, charge, and encumbrance registered against it. In Ontario, liens and encumbrances are public information, registered with the provincial Land Registry the moment they take effect.
Ontario's land registration system is governed primarily by the Land Titles Act (R.S.O. 1990, c. L.5) and operated electronically by Teranet on behalf of the Government of Ontario through the POLARIS system. Almost every property in the province has now been converted from the older Registry System to the modern Land Titles System — a state-guaranteed register where what appears on title is what legally binds the land.
A complete Ontario Lien Search will typically uncover:
Mortgages and charges registered against the property
Construction liens filed under the Construction Act by contractors, subcontractors, workers, or material suppliers for unpaid work
Writs of execution filed by judgement creditors with the Sheriff and binding on land the debtor owns
Condominium liens filed under the Condominium Act, 1998 for unpaid common expenses
Tax liens filed by the Canada Revenue Agency (CRA), the Province of Ontario, or municipalities for unpaid property taxes
Certificates of pending litigation (CPLs) and other litigation-related registrations
Easements, rights-of-way, and restrictive covenants — non-financial encumbrances that still affect how the property can be used
Notices of security interest, cautions, and other title-affecting registrations
Not every registration works the same way, and Ontario has some tools that are worth understanding before you interpret your Lien Search results.
Construction Liens. Ontario's construction lien framework was substantially updated in 2018 and 2019, and the statute was renamed from the Construction Lien Act to the Construction Act. Under the Act, contractors, subcontractors, workers, and material suppliers can register a construction lien for unpaid work or materials. These liens can attach to residential, commercial, and multi-unit properties, and they must be cleared before closing. Time limits for preserving and perfecting a lien are strict — missing them can extinguish the lien entirely.
Writs of Execution. When a judgement creditor obtains a court order against a debtor in Ontario, they can file a writ of execution with the Sheriff for the enforcement region where the debtor owns property. The writ binds any land the debtor owns in that region, and it will surface on a Lien Search. Any registered writ needs to be dealt with before a property can transfer with clean title.
Condominium Liens. For condo units, unpaid common expenses can result in a lien registered under the Condominium Act, 1998. These liens take priority over most other charges — including many mortgages — which is why a Lien Search is essential due diligence before buying any condominium unit in Ontario.
Property Tax Arrears. Ontario municipalities can register liens for unpaid property taxes, and in serious cases can proceed to tax sale. Any tax arrears should be identified and resolved before closing.
Certificates of Pending Litigation. A CPL registered against title signals ongoing litigation involving the property — a critical red flag for any buyer or lender.
Direct access to Ontario Land Registry data is available through Teranet's OnLand portal and ServiceOntario, but these systems can be complex to navigate and typically require account setup for repeated use. Our online platform connects to the same official land registration source on your behalf, so you can run a full Lien Search Ontario from any device in just a few clicks — no OnLand account needed.
To get started, you'll need one of the following:
The street address is the simplest place to start for most residential and commercial properties across Ontario.
Every parcel in Ontario's Land Titles System has a unique nine-digit PIN. If you have it, this is the fastest and most accurate way to retrieve encumbrance data.
The legal description (Lot, Plan, Concession, Township) is shown on a recent MPAC assessment notice, property tax bill, or any registered title document.
A name-based search will return parcels registered under an individual or company in Ontario — useful for asset searches, estate work, and corporate due diligence. For writs of execution, the search is name-based by design.
If you have a registration number from a previous transaction, we can pull the current encumbrance details directly.
Every buyer in Ontario should run a Lien Search before closing. It's the only reliable way to confirm the title is clean and that you won't inherit somebody else's debt. Mortgages should be paid out, construction liens cleared, condo arrears settled, and any writs of execution discharged before keys change hands.
Lenders, private mortgage providers, and anyone accepting Ontario real estate as security need to know exactly where they sit in the priority of registered claims. A Lien Search shows you who else has a registered interest — and how much equity might actually be available.
If you're owed money for work performed or materials supplied on an Ontario project, a Lien Search lets you confirm whether a construction lien has already been registered — and whether the property has enough equity to make preserving your own lien worthwhile under the Construction Act.
For any condo transaction, checking for outstanding common expense arrears is essential. Condominium liens take priority over most other charges, so an unresolved lien can significantly affect a lender's willingness to finance the unit.
Legal professionals across Ontario rely on accurate, up-to-the-minute encumbrance information to prepare requisition letters, statements of adjustments, and closing reports. Our platform delivers official results fast.
When settling an estate or working through a matrimonial matter, a Lien Search reveals the true equity in any real property involved — essential for fair distribution and accurate accounting.
