Credit Card Lawsuit in Ontario: What the Bank or Debt Buyer Has to Prove
If a bank or a debt buyer has sued you over a credit card in Ontario, it is the plaintiff’s job to prove its case, not yours to disprove it. It must show, on a balance of probabilities, that you agreed to the terms it relies on, that the balance and interest rate are right, that it owns the debt if it is not the original lender, and that it sued inside the limitation period. Most of these claims land in Small Claims Court, where the plaintiff’s documents must be disclosed before trial. Here is what each piece of proof looks like.
The agreement, the balance and the interest rate
A credit card claim is a contract claim, so the plaintiff must first prove the contract: the cardholder agreement, as it stood at the time. Cardholder agreements typically say that using the card is acceptance of their terms, and a history of purchases and payments is usually treated as strong evidence that you agreed to something. The plaintiff still has to show which terms applied, above all the interest rate.
The balance is normally proven by monthly statements running up to charge-off. Interest must be pleaded at a stated rate and tied to the contract; otherwise the fallback is prejudgment interest under s. 128 of the Courts of Justice Act, typically far below a card rate, subject to the court’s discretion under s. 130. In Small Claims Court, any document the claim is based on must be attached to the claim or its absence explained (r. 7.01(2)).
When a debt buyer sues: proving the chain of assignment
A debt buyer carries an extra burden: proving it owns your particular debt. That means the bill of sale from the bank, a schedule identifying your account within the portfolio and, if the debt was resold, the same documents for every link in the chain. It also means notice: under s. 53(1) of the Conveyancing and Law of Property Act, an absolute written assignment of a debt passes the legal right to sue on it “from the date of” express written notice to the debtor, and in the Superior Court an assignee must join the original creditor as a party unless the assignment is absolute and written notice has been given (r. 5.03(3)). A debt buyer that cannot show both the assignment and the notice has a real gap; see whether a debt buyer’s claim is enforceable and what to expect from PRA Group.
Was the claim started in time?
The Limitations Act, 2002 gives a creditor two years from the day the claim was “discovered” to sue (s. 4). Discovery means the creditor knew, or ought reasonably to have known, of the loss and that a lawsuit was an appropriate remedy (s. 5(1)), presumed to be the day of the act or omission unless the plaintiff proves otherwise (s. 5(2)). For a credit card that is generally the default, the missed payment after which the account never recovered, so the two years usually run from around that date, not from charge-off or the sale of the debt. A written, signed acknowledgment or a part payment resets the clock (s. 13(1), (10), (11)), but only if made before the two years ran out (s. 13(9)). The limitation defence must be pleaded, and it is a complete defence where it applies. See debt that is too old to sue on and the limitation period defence.
How bank records get into evidence
Section 35 of Ontario’s Evidence Act admits a “writing or record” of a transaction made in the usual and ordinary course of business (s. 35(2)), provided the party relying on it gives at least seven days’ notice; the other parties are entitled to inspect it (s. 35(3)). The circumstances of a record’s making, including the affiant’s lack of personal knowledge of your account, go to weight rather than admissibility (s. 35(4)), the real issue with debt buyer affidavits sworn by staff describing another company’s records. In Small Claims Court, r. 18.02 goes further: any document served at least 30 days before trial is received in evidence unless the judge orders otherwise, and to cross-examine its author you must summon them (r. 18.02(4)). Documents not attached to the claim must be served at least 14 days before the settlement conference (r. 13.03(2)).
Summary judgment (Rule 20) in plain terms
Rule 20 of the Rules of Civil Procedure applies in the Superior Court of Justice, which hears claims above the Small Claims limit (Courts of Justice Act, s. 23(1.1)). After you deliver a defence, the plaintiff can move on affidavits (r. 20.01(1)), and the court must grant judgment if satisfied there is “no genuine issue requiring a trial” (r. 20.04(2)(a)). The judge can weigh evidence, assess credibility and draw inferences (r. 20.04(2.1)). The rule that catches unprepared defendants is r. 20.02(2): you cannot rest on the denials in your defence, but must file evidence setting out specific facts that show a real issue needs a trial. Higher-scale costs can follow unreasonable or bad-faith conduct on the motion (r. 20.06). The Rules of the Small Claims Court have no summary judgment rule; there, the plaintiff’s closest tools are a motion to strike a defence that discloses no reasonable defence (r. 12.02) and the settlement conference, where the judge can recommend eliminating unsupported defences (r. 13.04).
Putting the plaintiff to proof without being obstructive
Requiring proof is different from refusing to engage. Legitimate: a defence that pleads the specific issues you actually have (limitation, missing proof of assignment or notice, a balance or rate that does not match your statements, identity if the account is not yours); asking for the agreement, statements, bill of sale and notice; and summoning the affiant if the records are contested. Not legitimate: a bare “I deny everything,” demanding a wet-ink original for its own sake, or skipping the settlement conference. Small Claims judges can strike pleadings that are a waste of time or an abuse of process (r. 12.02(1)(c)). If you used the card and the numbers are right, putting the plaintiff to proof usually improves the number or the terms rather than defeating the claim; limitation is the exception that can end it outright.
Frequently asked questions
Do they need my signed application to win? Usually not. Use of the card and a history of payments is strong evidence of a contract, but the plaintiff still has to prove which terms applied, including the interest rate.
The debt buyer only has a redacted spreadsheet. Is that enough? The standard proof is a bill of sale plus a schedule entry identifying your account, with written notice of the assignment. A spreadsheet the debt buyer generated itself is much weaker.
Does a payment to a collection agency restart the two years? Only if it was made before the two years ran out: a part payment to the creditor or its agent then restarts the clock. A payment made after expiry does not revive the claim.
Can the bank get summary judgment in Small Claims Court? No. Rule 20 is a Superior Court rule. In Small Claims Court the plaintiff must prove its case at trial, or move to strike a defence that discloses no reasonable defence.
