A Practical Guide to Security Registration
The Personal Property Security Act (Ontario), universally known as the PPSA, is the statute that governs how security interests in personal property are created, registered, and enforced in Ontario. If you’re lending money secured by business assets, buying a business, taking equipment as collateral, or entering any transaction where personal property backs an obligation, the PPSA is the framework that determines whether your security interest is legally effective and where you stand relative to other creditors.
Getting it right matters. A security interest that isn’t properly attached and perfected can be unenforceable, subordinate to other creditors, or void in a borrower’s insolvency, none of which are outcomes a lender or secured creditor can afford
What Is “Personal Property” Under the PPSA?
The PPSA applies to personal property which means everything that isn’t real property (land and buildings). Under the Act, personal property includes goods (equipment, inventory, consumer goods), instruments (promissory notes, bills of exchange), documents of title, chattel paper, securities, intangibles (accounts receivable and intellectual property rights), and money.
Several interests fall outside the PPSA’s scope: liens arising by operation of law, interests in insurance policies and annuities, interests in land and land leases, and assignments made for the general benefit of creditors. Where a transaction involves a mix of real and personal property – a commercial acquisition with both land and equipment, for example different legal regimes apply to each component, which is one reason M&A due diligence should always include a PPSA search alongside a title search.
Attachment: When Does a Security Interest Become Enforceable?
Attachment is the first step. A security interest only becomes enforceable against the debtor once it has attached, and three conditions must be met for that to happen.
First, the secured party must give value. In most lending transactions, this means advancing funds, extending credit, or providing some other form of consideration. Second, the debtor must have rights in the collateral;hey must own it, have the power to transfer it, or have some other legally sufficient interest. Third, either the debtor must have signed a security agreement that adequately describes the collateral, or the secured party must have taken possession or control of the collateral itself.
If any one of these three elements is missing, the security interest has not attached and cannot be enforced against the debtor regardless of what the parties intended.
Perfection: Protecting Your Interest Against the World
Attachment makes a security interest enforceable between the parties. Perfection does something different: it protects the secured party’s claim against third parties other creditors, subsequent purchasers, and trustees in bankruptcy.
Perfection is most commonly achieved by registering a financing statement in Ontario’s PPSA registry. Registration provides public notice that a security interest exists in specified collateral. Once registered, the secured party’s interest generally takes priority over subsequently registered or unregistered interests in the same collateral.
For certain types of collateral, perfection can alternatively be achieved by taking possession (for negotiable instruments, for example) or by obtaining control (for investment property and deposit accounts). The method matters different types of collateral have different perfection rules, and choosing the wrong method can leave a security interest unperfected even if a financing statement has been filed.
Purchase Money Security Interests (PMSIs) and Super-Priority
One of the most important and most misunderstood concepts under the PPSA is the Purchase Money Security Interest, or PMSI. A PMSI arises when a secured party finances the acquisition of specific collateral and takes a security interest in that same collateral to secure repayment. Equipment financing, conditional sales contracts, and vendor-take-back arrangements are common examples.
A PMSI that is properly perfected within the required timeframe (generally 10 days of the debtor taking possession of the collateral for goods other than inventory) achieves super-priority it ranks ahead of even earlier-registered security interests in the same collateral. This is a significant exception to the general first-to-register rule and has important implications for lenders holding all-assets security. A lender with a general security agreement (GSA) covering all of a borrower’s assets needs to monitor for PMSI registrations that could carve out equipment or inventory from that blanket coverage.
All-Assets Registration vs. Specific Collateral Registration
When a lender takes security over a borrower’s entire business, they typically register a financing statement covering “all present and after-acquired personal property” commonly called an all-assets or general security agreement (GSA) registration. This captures everything the debtor currently owns and everything they acquire in the future.
Specific collateral registrations, by contrast, cover identified assets a piece of equipment, a specific receivable, or a defined pool of inventory. These are used by equipment financiers, vendors under conditional sales contracts, and lenders whose security is limited to particular assets.
Understanding the scope of what’s registered and searching for competing registrations is a critical step in any commercial financing transaction and in the due diligence process when acquiring a business.
Priority: It’s Not Simply First to Register
The PPSA has a general rule: as between competing registered security interests in the same collateral, the first to register wins. But priority analysis is rarely that straightforward in practice.
PMSIs override the first-to-register rule for specific collateral, as described above. Certain statutory liens including repair and storage liens under Ontario’s Repair and Storage Liens Act can take priority over registered PPSA interests without appearing in the PPSA registry at all. Security created under federal statutes, including the Bank Act, operates under a parallel regime and can create priority complications that a PPSA search alone won’t reveal.
Reading a search certificate tells you what’s registered under the PPSA. It doesn’t tell you about unregistered statutory interests, federal security, or possessory liens, all of which require separate investigation. A complete priority analysis requires looking beyond the registry.
Registration Renewals and Lapse
A PPSA financing statement is not permanent. Registrations must be renewed before they expire or they lapse, and a lapsed registration means the security interest is no longer perfected. In a priority dispute or insolvency, a lapsed registration can be catastrophically expensive.
Registration periods vary depending on what was selected at the time of filing: a secured party can register for a fixed term or on an indefinite basis. Lenders and secured creditors should maintain a system for tracking registration expiry dates and renewing well in advance. This is a routine part of secured lending administration that is easy to overlook and difficult to fix after the fact.
PPSA in M&A Transactions
In any purchase of a business, whether structured as an asset purchase or a share purchase, PPSA due diligence is non-negotiable. A buyer in an asset transaction needs to search the PPSA registry to confirm that the assets being acquired are free of undisclosed security interests and must require discharge of any registrations as a condition of closing. A buyer in a share transaction inherits the corporation’s liabilities, including any obligations secured under existing PPSA registrations, and needs to understand what security the corporation has granted and to whom.
Closing conditions in a properly structured purchase agreement always include PPSA searches and discharges where required. Missing this step can mean acquiring assets subject to a secured creditor’s claim a problem that typically surfaces only after closing, when it is far more expensive to resolve.
