Uncovering Hidden Liens on Business Assets in Ontario: A Buyer's Guide

Picture this: you buy the equipment and inventory of a small manufacturing business, pay the agreed price, and start operating. Months later, a lender shows up saying it has a registered security interest against the very equipment you're using — and it's entitled to seize it. This scenario is exactly what a search for hidden liens is designed to prevent, and it's one of the more consequential steps a buyer can skip by accident.

In Ontario, security interests in equipment, inventory, and other business property are registered and governed under the Personal Property Security Act (PPSA). A lien that isn't paid off or discharged before you buy the asset can, in the wrong circumstances, still follow that asset into your hands.

This guide explains how these liens arise, how to search for them, and what to do when a search turns one up.

Why Liens Can Survive a Sale

The PPSA sets out a registration and priority system for security interests in personal property — the kind of interest a lender or supplier takes when it finances equipment, inventory, or receivables. A seller can, whether through oversight or financial pressure, sell you an asset that still has a registered interest against it, if that underlying debt hasn't actually been paid off and the registration discharged.

The practical risk is straightforward: you can pay full price for equipment in good faith and still end up with a secured lender's claim attached to it, because the registration — not the sale itself — is what the PPSA system tracks.

What a PPSA Search Actually Shows

A search run against the seller's exact legal name (and any prior names) will typically show:

• The registered secured party's name
• A description of the collateral covered
• The registration date and its expiry
• Whether the registration has been amended or partially discharged

A search shows what's registered — it's a strong screening tool, but it isn't a guarantee that every claim against an asset has been formally registered, so it works best alongside seller representations rather than instead of them.

Ordering the Search: What It Costs

These are ministry-direct fees as of mid-2026 — verify the current figure before relying on it, since a search or filing agent may charge more than the direct government rate.

What Happens When a Search Turns Up a Registered Interest

1. Identify the secured party and, usually through your lawyer, confirm the outstanding balance owed against the specific collateral.
2. Obtain a payout and discharge undertaking — commonly built into closing, where sale proceeds are used to pay off the debt in exchange for a registered discharge.
3. Make the discharge a closing condition, so the deal doesn't complete until the registration is actually cleared, or is being cleared simultaneously with closing.
4. Consider a holdback if a clean discharge can't be confirmed by the closing date, so funds remain available to resolve it afterward.

Protecting Yourself Beyond the Search

• [ ] Run the PPSA search early enough in due diligence to actually negotiate around what it finds
• [ ] Search under the seller's exact legal name and any name it has previously used
• [ ] Get seller representations that the purchased assets are being sold free of liens except as specifically disclosed
• [ ] Require discharge of any registered interest as a condition of, or concurrent with, closing
• [ ] Re-run the search close to the closing date — a new registration can appear after your first search

Share Deals: A Different Kind of Exposure

In a share purchase, the corporation continues to own its assets subject to whatever is already registered against them — the lien isn't "surviving a sale" in the same sense, because there's no change in who legally owns the asset. Instead, the buyer inherits the lien as part of acquiring the company itself, which is one more reason share-deal due diligence needs to look at the corporation's full PPSA profile, not just its contracts and financials.

A related use of the PPSA worth knowing: where a seller finances part of the purchase price through a vendor take-back, the seller typically registers its own PPSA interest against the purchased assets as security for that arrangement.
