- A straightforward matter that settles early may cost a few thousand dollars in legal fees; a fully contested matter through trial can cost tens of thousands or more.
- Ontario Superior Court filing fees alone run into the hundreds of dollars, before any legal fees are considered.
- The losing party in Ontario civil litigation is typically ordered to pay a portion of the winning party's legal costs — but rarely the full amount.
- Offers to settle made under Rule 49 of the Rules of Civil Procedure can significantly affect the cost consequences at the end of a case.
- Claims of $50,000 or less generally belong in Small Claims Court, which is dramatically less expensive than Superior Court litigation.

The Short Answer: A Few Thousand Dollars to Well Over $50,000
The cost of suing someone in Ontario varies enormously depending on how far the matter proceeds. A dispute resolved through a demand letter or early negotiation might cost a few thousand dollars in legal fees. A fully contested matter that proceeds through discovery, motions, and trial in the Ontario Superior Court of Justice can easily cost $50,000 or more in combined legal fees and disbursements.
Three separate categories of expense make up the total cost of a lawsuit: court filing fees, your own legal fees, and disbursements (out-of-pocket expenses like expert witnesses). Ontario's cost award system also means the outcome of your case can shift some of these costs onto the other party — or onto you, if you lose.
Court Filing Fees
Filing a Statement of Claim in the Ontario Superior Court of Justice requires payment of a court fee, currently several hundred dollars, with additional fees payable at later stages — such as setting the matter down for trial, or filing certain motions. These government fees are separate from, and much smaller than, legal fees, but they are a real cost from the outset.
Legal Fees by Stage
Legal fees typically accumulate as a matter progresses through each stage of litigation. Roughly speaking:
| Stage | Typical Legal Fee Range | Notes |
|---|---|---|
| Demand letter / pre-litigation negotiation | $500 – $2,500 | Often resolves the matter without filing |
| Drafting & filing Statement of Claim/Defence | $1,500 – $5,000 | Depends on complexity of pleadings |
| Discovery (documents & examinations) | $5,000 – $20,000+ | Scales with volume of documents and witnesses |
| Motions | $2,000 – $10,000 per motion | Highly variable based on complexity |
| Mediation | $1,500 – $5,000 | Plus mediator's fee, often split between parties |
| Trial | $15,000 – $50,000+ | Depends heavily on trial length and complexity |
Every case is different. Simple, single-issue disputes can cost far less than these ranges suggest; complex commercial litigation with multiple parties and expert evidence can cost significantly more. We provide a specific estimate based on your actual matter during a free consultation.
Disbursements & Expert Costs
Beyond legal fees, litigation involves out-of-pocket costs called disbursements — including process server fees to serve documents, court reporter and transcript fees for examinations, and expert witness fees for matters requiring specialized evidence such as business valuations, medical opinions, or engineering assessments. Expert fees in particular can range from a few thousand dollars to tens of thousands for complex reports and trial testimony.
How Cost Awards Work in Ontario
Unlike some jurisdictions where each party simply bears its own costs, Ontario follows the general principle that the losing party contributes to the winning party's legal costs. However, this rarely means full reimbursement.
Partial Indemnity vs. Substantial Indemnity Costs
Courts most commonly award partial indemnity costs — typically 50% to 70% of the winning party's actual legal fees. In limited circumstances, such as where a party has behaved unreasonably during the litigation, a court may award substantial indemnity costs (closer to 90% of actual fees) as a penalty.
Even a successful plaintiff or defendant should expect to absorb a meaningful portion of their own legal costs. This is an important factor to weigh when deciding whether pursuing or defending a claim makes financial sense.
Offers to Settle (Rule 49) and Their Cost Consequences
A formal offer to settle made under Rule 49 of the Rules of Civil Procedure can have significant cost consequences. If a party rejects a reasonable offer and the eventual result at trial is less favourable to them than the offer, the court can penalize them with costs — for example, denying them their own costs after the date of the offer, or requiring them to pay the other side's costs from that point forward.
A well-timed, reasonable offer to settle is one of the most effective tools in litigation — it creates real financial pressure to settle and protects your cost position if the matter proceeds to trial regardless.
Is Small Claims Court a Cheaper Alternative?
If your claim is $50,000 or less, Small Claims Court offers a significantly less expensive alternative to Superior Court litigation — lower filing fees, simplified procedures, and generally lower legal fees due to the more streamlined process. We assess whether your claim qualifies and whether Small Claims Court makes sense for your specific situation.
How to Reduce Your Litigation Costs
- Try a demand letter first. Many disputes resolve without ever needing to file a claim.
- Provide organized, complete documentation early. Disorganized files increase the time — and therefore cost — of every stage.
- Consider mediation seriously. Settling at mediation avoids the most expensive remaining stages of litigation.
- Make a well-considered offer to settle. A reasonable Rule 49 offer can pressure early resolution and protect your cost position.
- Ask about flat or staged fee arrangements. Where available, these provide more predictable costs than pure hourly billing.
A business owed $80,000 sends a firm demand letter through a lawyer, and the debtor settles for $65,000 within a month — total legal cost: a few thousand dollars. A similar dispute that proceeds through full discovery and a two-day trial might cost $40,000 or more in combined legal fees, even after a partial cost award in the winning party's favour.

Frequently Asked Questions
A demand letter and negotiated settlement, without ever filing a claim, is by far the least expensive option. If litigation becomes necessary, Small Claims Court (for claims up to $50,000) is significantly less expensive than Superior Court litigation.
Not entirely. Ontario courts typically award the winning party "partial indemnity" costs — often 50–70% of their actual legal fees — rather than full reimbursement, meaning you should expect to bear a portion of your own costs even if you win.
The losing party is typically ordered to pay a portion of the winning party's legal costs, in addition to their own. This is an important consideration when deciding whether to pursue or defend a claim.
A formal offer to settle made under Rule 49 of the Rules of Civil Procedure creates cost consequences if the final result is less favourable to the party who rejected it than the offer itself. This mechanism encourages parties to make and accept reasonable settlement offers.
Superior Court filing fees for a Statement of Claim run several hundred dollars, with additional fees for other steps such as setting a matter down for trial. These court fees are separate from — and much smaller than — legal fees.
Yes. Disbursements — including court filing fees, process server fees, transcript costs, and expert witness fees — can add up significantly, particularly in matters requiring expert reports or extensive document production.
Some stages of litigation, or straightforward matters, can be handled on a flat or staged fee basis, giving you more cost predictability than pure hourly billing. We discuss fee structure options during your free consultation.
It depends on the amount, the strength of your case, and whether Small Claims Court is available (for claims up to $50,000). For smaller amounts, the cost of Superior Court litigation can exceed the amount recovered, making Small Claims Court or negotiation the more sensible path.
