Ordinary contract damages are meant to put the wronged party in the position they would have been in if the contract had been performed — nothing more. Punitive damages for breach of contract are the exception: an additional amount, on top of compensation, meant to punish the breaching party and deter similar conduct in the future. Ontario courts award them rarely, and only where the facts go well beyond an ordinary, even careless, breach.

This article explains what makes a breach of contract exceptional enough to attract punitive damages, and why most contract disputes — even serious ones — never get there.

The Default Rule: Contract Damages Compensate, They Don’t Punish

Ontario contract law is built around compensation, not punishment. If a business breaches a supply agreement, or an individual walks away from a deal, the standard remedy simply puts the other side in the financial position they would have occupied if the contract had been honoured. Courts do not normally add extra damages just because the breach was inconvenient, costly, or even deliberate.

This matters because breaching a contract, on its own, is not treated as morally wrongful in Ontario law in the way that fraud or another independent wrong might be. Parties sometimes make a considered business decision to breach and pay damages rather than perform — that alone does not open the door to punishment.

What Can Open the Door to Punitive Damages

Punitive damages become available only in narrow circumstances, generally where the defendant’s conduct involves something beyond the breach itself — conduct that is independently wrongful and that is:

The manner of the breach matters as much as the breach itself. How a party breached — and how it treated the other side while doing so — can matter more to a punitive damages analysis than the fact of the breach alone.

Where This Sometimes Comes Up

Punitive damages claims in a contract context tend to surface in disputes involving:

Even in these categories, punitive damages remain the exception rather than the rule. Most contract disputes, even acrimonious ones, are resolved through ordinary compensatory damages.

Courts Keep a Tight Rein on the Amount

Where punitive damages are awarded, Ontario courts require the amount to be proportionate — no larger than what is rationally necessary to achieve punishment and deterrence in the circumstances. Courts do not use punitive damages as a way to transfer wealth to the plaintiff beyond what compensation and proportionate punishment require, and an award that is disproportionate to the misconduct can be reduced on appeal.

Punitive Damages at a Glance

QuestionTypical Answer
Is a deliberate breach enough on its own?No — deliberate is not the same as independently wrongful
Do these claims come up often?No — they are the exception, not the rule
Are they meant to compensate the plaintiff?No — they punish and deter the defendant
Is the amount unlimited?No — courts require proportionality to the misconduct

Frequently asked questions

Does a deliberate breach automatically qualify for punitive damages?

No. Choosing to breach a contract — even deliberately, for business reasons — is not, on its own, enough. Courts look for conduct that is independently wrongful or that involves bad faith, not just an intentional business decision to breach and pay damages instead of performing.

Can I claim punitive damages in Small Claims Court?

Punitive damages claims can theoretically arise in any civil court, but the exceptional evidence and legal argument they require often makes them more suited to Superior Court litigation with legal representation, particularly where the underlying facts are complex.

Are punitive damages common in Ontario contract cases?

No — they remain a rare exception. The vast majority of Ontario breach-of-contract cases are resolved through ordinary compensatory damages, and punitive damages require conduct well beyond a typical, even a bad, breach.

What is the difference between punitive damages and a penalty clause?

They are different concepts entirely. A penalty clause is a contract term that a court can refuse to enforce because the parties tried to privately agree to punishment. Punitive damages are an amount a court itself adds to an award because of a defendant’s exceptional conduct — no clause in the contract is needed for a court to consider them.
