Every debt portfolio transaction in Ontario involves a legal act known as assignment: the transfer of the creditor's rights in a receivable from the seller to the buyer. The commercial mechanics of a portfolio sale receive significant attention, but the underlying legal framework matters just as much. A poorly structured assignment can undermine the buyer's ability to enforce the accounts and expose the seller to ongoing obligations that should have ended at closing.

This article examines the legal requirements for assigning consumer debt in Ontario, the distinction between the two recognized forms of assignment, and the practical implications for both parties in a portfolio sale.

Ontario law recognizes two distinct forms of debt assignment, each with different requirements and consequences. The distinction matters for structuring a portfolio sale that gives the buyer clean, enforceable ownership of the accounts.

A legal assignment is governed by section 53(1) of Ontario's Conveyancing and Law of Property Act (CLPA).4 To qualify as a legal assignment, the transfer must meet three conditions: it must be absolute (not conditional or partial), it must be in writing and signed by the assignor, and express written notice must be given to the debtor. When all three conditions are satisfied, the assignee can enforce the debt directly against the debtor without involving the original creditor in the proceedings.

An equitable assignment arises when the parties intend to transfer the debt but do not satisfy all of the statutory requirements. The most common scenario is a transfer where no notice has been given to the debtor. Equitable assignments are valid between the parties, but they carry a significant practical limitation: the assignee generally cannot sue the debtor in its own name. Instead, the original creditor must be joined as a party to the action, which creates ongoing dependency and potential delays.

For institutional portfolio transactions, legal assignment is strongly preferred. It provides the buyer with independent enforcement rights and creates a clean separation between seller and buyer at closing. Sellers should ensure that the purchase and sale agreement contemplates the delivery of proper assignment instruments and that the notice process is built into the closing or transition timeline.

Notice Requirements and Debtor Communication

The notice requirement is the element that most frequently distinguishes a legal assignment from an equitable one. Under the CLPA, the assignee must provide express written notice to the debtor that the debt has been assigned. Until that notice is delivered, the assignment remains equitable in nature, regardless of how clearly the parties documented the transfer between themselves.

The statute does not prescribe a specific form for the notice. It must, however, clearly identify the debt, state that the debt has been assigned, and identify the new creditor. In practice, most portfolio buyers send a written notice letter to each debtor at their last known address. The letter typically includes the original creditor's name, the account reference number, the outstanding balance, and the buyer's contact information.

Timing is a practical consideration. Many purchase and sale agreements require the buyer to send assignment notices within a specified period after closing, often 30 to 60 days. Some sellers prefer that the buyer delay notices until a transition period has concluded, particularly where the seller is redirecting payments or winding down servicing operations. The parties should align on this timeline during contract negotiation to avoid confusion.

Note that until the debtor receives notice, the debtor is entitled to continue making payments to the original creditor. Any payments made to the assignor in good faith before notice is received discharge the debtor's obligation to that extent. Sellers who receive post-sale payments must have a process for forwarding those funds to the buyer promptly.

Assignee Rights and Limitations

A fundamental principle of assignment law in Ontario is that the assignee takes the debt "subject to equities." This means the buyer acquires exactly the rights the original creditor held, and the debtor retains every defence, set-off, or counterclaim that was available against the original creditor at the time of the assignment.

For portfolio buyers, this has several practical implications. If the original creditor breached the underlying contract, the debtor can raise that breach as a defence against the buyer. If the debtor had a valid set-off against the original creditor, that set-off survives the assignment. If the original creditor made representations about the account that created an estoppel, the buyer is bound by those representations.

Thorough due diligence before acquiring a portfolio is critical. Buyers need to understand the history of the accounts, the terms of the original credit agreements, and any disputes or complaints that may have arisen during the creditor's ownership. Sellers who provide complete and transparent information about account history reduce the risk of post-sale disputes and putback claims.

The assignee also steps into the procedural shoes of the original creditor for litigation purposes. In Ontario Small Claims Court or Superior Court proceedings, the buyer must be able to demonstrate a valid chain of title from the original creditor through each successive assignment. Gaps in the chain of title, missing assignment agreements, or incomplete documentation can jeopardize the buyer's standing to pursue the account.

For sellers, maintaining clean records of prior assignments is particularly important when the portfolio includes accounts that were themselves acquired from another party. Each link in the chain must be documented with a written assignment instrument that identifies the accounts transferred and is signed by the assignor.

Limitation Periods and Assignment

The interaction between debt assignment and limitation periods is frequently misunderstood.2 Under the Limitations Act, 2002, the basic limitation period for most civil claims is two years from the date the claim was discovered. For consumer debt, the discovery date is typically the date of the last payment or the date of default, whichever is later.

The assignment of a debt does not reset this clock. The limitation period continues to run from the original discovery date, regardless of how many times the debt changes hands.3 A buyer who acquires an account that is 18 months into its limitation period has, at most, six months remaining to commence legal proceedings.

This principle is firmly established in Ontario case law.1 Courts have consistently held that the assignment of a chose in action does not create a new cause of action or restart the limitation period. The rationale is obvious: allowing assignments to reset limitations would let creditors extend their enforcement window indefinitely by selling and reselling the debt.

For portfolio pricing, limitation period status is a critical variable. Accounts within the limitation window are generally more valuable because the buyer retains the option to pursue legal remedies if voluntary resolution efforts are unsuccessful. Accounts beyond the limitation period can still be collected through voluntary payment arrangements, but the absence of a litigation option reduces the buyer's leverage and, consequently, the portfolio's value.

Sellers should include accurate last-payment dates and default dates in the data tape so buyers can independently verify limitation period status. Discrepancies between the seller's records and the actual limitation status can give rise to putback claims or warranty disputes after closing.

One important nuance: an acknowledgment of the debt or a partial payment by the debtor after the assignment can restart the limitation period under the Limitations Act, 2002. But this must be a voluntary act by the debtor; the assignment itself has no such effect.
