Someone owes you money, broke a contract, or caused you real harm — and you are right. But being right and being smart about pursuing a claim are two different questions. Before you file anything, it is worth doing a cost-benefit analysis on your potential lawsuit, the same way you would evaluate any other decision with real financial consequences.
Ontario courts do not screen claims for whether they make financial sense before letting you file them. That job falls to you, ideally with a lawyer's help early enough that you can still change course. This guide walks through the factors that actually determine whether a claim is worth pursuing.
Why "I'm Right" Isn't the Only Question
Winning a lawsuit and coming out ahead financially are not the same thing. You can have a strong claim, win at trial, and still end up worse off than if you had never sued — because of what it costs to get there, how long it takes, and whether the other side can actually pay once you have a judgment.
A proper cost-benefit analysis forces you to separate the moral question ("were they wrong?") from the practical one ("does pursuing this make financial sense for me?"). Both questions matter. Only one of them belongs in your decision about whether to spend money on litigation.
The Four Factors That Actually Matter
Four variables drive almost every litigation cost-benefit decision. None of them can be assessed in isolation — a strong claim against a judgment-proof defendant is still a bad bet.
| Factor | The Question to Ask |
|---|---|
| Claim value | What is the realistic recovery, not the best-case number? |
| Costs risk | What will you spend to get there, and what happens if you lose? |
| Collectability | If you win, can the other side actually pay? |
| Time | How long will this take, and what is your time worth? |
Each factor can independently make a claim not worth pursuing, even if the other three look favourable.
Claim Value: Be Honest About the Realistic Number
Start with what you could realistically recover — not the number that would feel satisfying, but the amount a court would likely award if you proved your case. Inflated claims that include speculative or emotional damages rarely survive scrutiny and can distort your entire cost-benefit picture.
If part of your claim is for money that changes value over time — unpaid invoices, a loan, damages from a breach — remember that courts can add interest to a judgment under the Courts of Justice Act. Both the rate used before judgment and the rate used after judgment are set periodically by the province, so treat any specific rate you have heard as something to confirm at the time you need it, not a fixed number to plan around today.
Costs Risk: Litigation Isn't a One-Way Bet
Ontario civil litigation generally follows a "loser pays" approach to costs: the unsuccessful party is usually ordered to contribute toward the other side's legal costs, typically on a partial indemnity basis. The court always has discretion over the amount and scale, so this is a real financial exposure, not a formality — if you lose, you are not just out your own legal spend.
This cost risk should weigh more heavily as claim value drops. A modest claim carries the same structural downside as a large one, just with a much thinner margin for it to still make sense.
Collectability: A Judgment Is a Piece of Paper Until You Enforce It
A civil judgment does not pay itself. Once you win, you still need to enforce it — through tools like garnishment, a writ of seizure and sale, or examining the debtor about their income and assets — and Ontario law does not do any of that automatically. The court does not monitor the debtor for assets; you, or your lawyer, have to find them.
Before you sue, ask a hard question: if you win, does the other side have money, income, or property to collect from? A judgment against someone with no assets and no steady income is a moral victory, not a financial one — at least until their circumstances change.
Time: The Cost You Rarely Put a Number On
Litigation takes time — yours, not just your lawyer's. Gathering documents, attending a settlement conference or examinations, and simply living with an unresolved dispute all have a real cost, even when nothing shows up on an invoice. Factor in how long you are willing to have this hanging over you, separate from the dollars involved.
A Quick Framework Before You Decide
- [ ] I know the realistic recovery amount, not the best-case one
- [ ] I understand that losing means contributing to the other side's costs too
- [ ] I have a reasonable belief the other side can actually pay a judgment
- [ ] I have accounted for the time this will take, not just the money
- [ ] I have tried, or seriously considered, resolving this without a lawsuit first
If most of these boxes are hard to check honestly, that is worth pausing on before you file.
Frequently asked questions
Is there a minimum amount that makes a lawsuit worth it in Ontario?
There is no fixed dollar threshold — it depends on the costs, collectability, and time involved in your specific situation. A claim that makes sense for one person may not make sense for another with different resources or risk tolerance.
Does winning automatically mean I get my legal costs back?
Not automatically, and not in full. Ontario courts have discretion over costs awards, and a successful party typically recovers only a portion of what they actually spent, usually on a partial indemnity basis.
What if I can't tell whether the other side has money?
This is common, and it is something a lawyer can help you investigate before you commit to litigation. In some cases, the only way to find out is after judgment, through an examination of the debtor.
Should I still sue if I know I probably won't collect much?
That depends on your goals. Some people pursue a claim for reasons beyond pure recovery — but you should make that choice with clear eyes about the financial trade-off, not by assuming collection will sort itself out.
