Before You Sue: An Ontario Decision Guide

Seven honest questions to ask before you file — so you don't win a lawsuit and lose anyway.

Who this is for: Anyone in Ontario weighing whether to take a dispute to court. You'll get the key questions to work through, a comparison of where a claim can go, a decision tree, and a simple cost/benefit worksheet — so you decide with your eyes open.

⚖️ This is a general guide, not legal advice. It can't account for your specific situation. Use it to get oriented, then confirm the details with a licensed Ontario lawyer.

Suing someone feels like the natural response to being wronged. Sometimes it is. But litigation costs money, eats time, and carries stress — and even a clear win is worthless if you can't collect. The point of this guide is to help you make a clear-eyed decision before you commit, not after.

Work through the seven questions below. If you get a shaky answer on any of them, that's a signal to slow down and get advice.

Question 1 — Do you have a valid legal claim?

Being treated unfairly isn't the same as having a claim a court can act on. A valid claim generally needs a recognized legal basis — a broken contract, a debt owed, property damaged, money paid for nothing delivered — and a loss the court can compensate.

Ask:

• Can you name what legal wrong happened (breach of contract, unpaid debt, negligence, etc.)?
• Can you point to a concrete loss (money out of pocket, property damaged)?
• Is there a remedy a court can actually give you?

⚠️ Watch out: "It's the principle" is a real feeling, but courts award remedies, not vindication. If there's no measurable loss and no remedy, litigation may not be the right tool.

Question 2 — Is it within the limitation period?

Ontario's Limitations Act, 2002 sets a deadline to start a lawsuit. Miss it and your claim is usually barred no matter how strong it is. The clock generally starts when you knew, or reasonably should have known, you had a claim.

⚠️ The basic limitation period is two years from the day the claim was discovered (Limitations Act, 2002, s. 4 — as of 2026). Some claims have shorter or different deadlines, so verify how the rules apply to your facts. If you're anywhere near a deadline, treat it as urgent and get advice now, not later.

Question 3 — Who is the right defendant, and can they pay?

Two separate problems, both fatal if you get them wrong.

The right defendant. Sue the actual legal entity responsible — the correct individual, or a business's exact registered name (not its trade name). Suing the wrong party can mean a judgment you can't use.

Their ability to pay. This is the question people skip — and regret. A judgment is only worth something if the defendant has money or assets to collect from. Someone with no income, no assets, and nothing to seize is sometimes called judgment-proof: you can win and still walk away with nothing but legal bills.

Ask:

• Is the defendant an individual, or a corporation? Is the corporation still active and solvent?
• Do they appear to have income, a business, property, or assets?
• If you won, how would you actually collect?

💡 Tip: A modest, collectible judgment beats a large, uncollectible one. Reality-check this before anything else.

Question 4 — What is it worth versus the cost, time, and stress?

Litigation has three currencies: money, time, and stress. Weigh all three against what you stand to recover.

• Money: filing fees, possible service and enforcement costs, and legal help if you use it. Even if you win, Ontario courts often award only limited costs — don't count on full reimbursement.
• Time: cases can run many months to over a year, with backlogs adding delay.
• Stress: disputes are draining, especially against someone you know or do business with.

If the realistic recovery is small and the cost, delay, and stress are high, the math may favour settling — or walking away.

Question 5 — What is the right forum?

Where your dispute belongs depends mostly on what it's about and how much it's worth.

⚠️ Watch out: Filing in the wrong forum wastes time and money. If you're not sure where your dispute belongs, ask a lawyer first.

Question 6 — Have you tried the alternatives?

Court is rarely the first good option. Before filing, consider:

• Direct negotiation — a frank conversation or email can resolve more than you'd think.
• A demand letter — a formal written demand often gets results without a lawsuit (see Treadstone's demand-letter guide).
• Mediation — a neutral third party helping both sides reach agreement, often faster and cheaper than trial.

These can save the relationship, the money, and the months. Even if you proceed to court later, having tried them shows you acted reasonably.

Question 7 — How strong is your evidence?

A claim is only as good as what you can prove. You carry the burden of proving your case, usually on a "balance of probabilities" (more likely than not).

Ask:

• Do you have documents — contracts, invoices, receipts, emails, texts, photos?
• Do you have witnesses with direct knowledge who'll cooperate?
• Can you put a clear number on your loss, with proof behind each figure?
• Is your version consistent and documented, or mostly your word against theirs?

💡 Tip: Strong paper beats strong feelings. If your evidence is thin, fix that (or rethink) before filing. See Treadstone's Evidence Organization Checklist.

Decision tree

Work down the branches. A "no" or "unsure" is a stop-and-get-advice point.

• Do you have a valid legal claim with a real loss?
  • No → litigation probably isn't the tool. Consider other options or let it go.
  • Yes ↓
• Are you within the limitation period?
  • No / unsure → get advice immediately — the deadline may decide this for you.
  • Yes ↓
• Is there a right defendant who can actually pay?
  • No (judgment-proof) → winning may get you nothing. Reconsider whether it's worth it.
  • Yes ↓
• Is the likely recovery worth the cost, time, and stress?
  • No → try to settle, send a demand letter, or walk away.
  • Yes ↓
• Have you tried alternatives (negotiation, demand letter, mediation)?
  • No → try them first; they're cheaper and faster.
  • Yes ↓
• Is your evidence strong enough to prove the claim?
  • No → strengthen it, or reconsider.
  • Yes → You're in a reasonable position to sue. Confirm the right forum and get advice on next steps.

Cost/benefit worksheet

Fill this in honestly. The goal is a number you can look at.

What you stand to gain

Amount you're claiming:               $____________
Realistic chance of winning (your honest %):  ________%
Realistic chance of actually collecting if you win:  ________%
Expected recovery (claim × win% × collect%):  $____________

What it will likely cost

Court filing fee (confirm current):   $____________
Service / process server (if any):    $____________
Possible enforcement costs:           $____________
Legal help (if you use it):           $____________
Your time (hours × what it's worth):  $____________
Total estimated cost:                 $____________

The gut-check

Expected recovery minus total cost:   $____________
Is that worth the months and stress?   [ ] Yes   [ ] No   [ ] Unsure

💡 Tip: If "expected recovery" is barely above (or below) your costs, that's your answer leaning toward settling or sending a demand letter instead.

Questions to ask yourself

• Am I doing this for a remedy, or mainly for the principle? (Both are valid — just be honest about which.)
• If I win but can't collect, will I regret the time and money spent?
• Have I given the other side a genuine chance to resolve this short of court?
• Is my evidence something I'd be comfortable handing to a judge today?
• Is the deadline safely open?
• Would an hour with a lawyer change how I see any of the above?
