Demand Letters in Ontario: Strategy, Timing, and Drafting Tips

Why the Demand Letter Matters More Than You Think

In Ontario civil litigation, the demand letter is often treated as a formality — a procedural step before the real work begins. This view is a mistake. A well-crafted demand letter is one of the most powerful tools in a litigator's arsenal. It can resolve a claim before a statement of claim is ever issued, saving the client months of litigation and thousands of dollars in legal fees. A poorly crafted demand letter, by contrast, can undermine your negotiating position, waive important rights, or invite a strategic response from defence counsel that puts your client at a disadvantage.

This article provides a practical, Ontario-specific guide to demand letter strategy, timing, and drafting — the kind of guidance that comes from experience, not textbooks.

When to Send a Demand Letter

Before Issuing a Claim — Almost Always

There is no statutory requirement to send a demand letter before issuing a statement of claim in most Ontario civil proceedings (with notable exceptions discussed below). However, there are compelling strategic reasons to do so:

• Cost Exposure: Under Rule 14 of the Rules of Civil Procedure, and as reinforced in cases interpreting Rule 57, a plaintiff who rejects a reasonable pre-litigation settlement offer may face substantial costs consequences. Sending a well-calibrated demand letter establishes your settlement position early and can protect your client on costs.
• Settlement Opportunity: A significant proportion of claims settle in response to a demand letter, particularly where liability is clear and the defendant's insurer is involved. The pre-litigation demand is your best opportunity to settle on favourable terms before both sides incur the costs of formal proceedings.
• Information Gathering: The response to your demand letter — including what the defendant says, what they do not say, and how quickly they respond — provides valuable intelligence for litigation strategy.
• Professionalism: Courts and tribunals view parties who attempt to resolve disputes before resorting to litigation more favourably. This can affect discretionary decisions, including costs awards.

Exception: The Municipal Notice Requirement

Claims against Ontario municipalities require written notice within 10 days of the incident under the Municipal Act, 2001 and the City of Toronto Act, 2006. While this notice is not technically a "demand letter," it serves a similar function and must be sent immediately — do not wait to draft a comprehensive demand. The notice need only provide sufficient detail to allow the municipality to investigate. A detailed demand can follow.

What to Include in a Demand Letter

A strong demand letter is detailed enough to be taken seriously but not so detailed that it gives the opposing side a road map of your litigation strategy. The essential elements include:

1. Identity and Representation

Identify your client, your firm, and your role as counsel. This signals that the claim is serious and that the client is prepared to litigate if necessary.

2. Factual Summary

Provide a clear, concise summary of the facts giving rise to the claim. Include dates, locations, and the specific acts or omissions that form the basis of liability. Avoid unnecessary detail — you are not writing a statement of claim. But include enough factual precision to demonstrate that your claim has substance.

3. Legal Basis

Identify the cause of action (negligence, breach of contract, etc.) and, where helpful, reference the key legal principles that support your claim. You do not need to provide a full legal memorandum, but a demand letter that articulates the legal basis for the claim is more credible than one that simply asserts that your client was wronged.

4. Damages

Specify the damages being claimed. For personal injury claims, this includes medical expenses, lost income, pain and suffering, and any other applicable heads of damage. Be specific where possible — a demand for "$150,000" is more credible than a demand for "substantial compensation."

5. Insurance Act Considerations

Ontario's Insurance Act imposes deductibles on pain and suffering awards in motor vehicle accident claims. Under Section 267.5, the deductible (adjusted annually for inflation) applies to claims where the pain and suffering award falls below a threshold. Your demand letter should address the deductible — either by explaining why the claim exceeds the threshold or by calculating the net amount after the deductible is applied. Failure to address this can lead to unrealistic expectations and ineffective negotiation.

6. Demand and Deadline

State clearly what your client is demanding and when you expect a response. The deadline should be realistic — typically 14 to 30 days — and should be stated firmly. "Please respond at your earliest convenience" is not a deadline. "We require your response within 21 days of the date of this letter" is.

Timing Strategy

When you send the demand letter can be as important as what it says:

• Medical Stability: In personal injury cases, do not send the demand until your client has reached maximum medical improvement or you have sufficient medical evidence to quantify the claim. Sending a demand too early — before you know the full extent of the injuries — can lock you into a position that undervalues the claim.
• Limitation Period Awareness: Do not wait so long that the limitation period becomes a pressure point. A demand sent 22 months after discovery gives the defendant a strategic advantage — they know you are running out of time and may delay their response accordingly.
• Strategic Timing: Consider when the demand will have the most impact. For claims against corporations, sending a demand before a fiscal quarter-end may increase urgency. For claims involving insurers, timing around renewal periods can create additional pressure.
• Responding to Limitation Expiry: If you are approaching a limitation date and the opposing party has not responded, do not rely on the demand letter to extend the limitation period. Issue a statement of claim to preserve the claim and continue settlement negotiations simultaneously.

What Happens After You Send the Demand

Understanding the likely responses helps you prepare:

• No Response: If the defendant does not respond within the deadline, your next step is typically to issue a statement of claim. The unanswered demand strengthens your position on costs if you obtain a judgment that exceeds your demand.
• Denial of Liability: A full denial requires you to assess whether settlement is possible on terms acceptable to your client, or whether the matter must proceed to litigation. The nature of the denial — whether it addresses your factual assertions, raises new facts, or simply rejects the claim — provides valuable intelligence.
• Low Counter-Offer: A low counter-offer is common and may be a negotiation opening rather than a final position. Consider whether the gap between your demand and the counter-offer can be bridged through negotiation.
• Acceptance: Less common but not rare, particularly where liability is clear. If the defendant accepts your demand, move promptly to document the settlement and ensure payment before the momentum fades.

Common Drafting Errors

The most frequent errors we see in Ontario demand letter practice include:

• Overstating the Claim: Inflated demands that bear no relationship to the evidence undermine credibility and make productive negotiation harder.
• Understating the Claim: Conversely, demands that undervalues the claim may leave money on the table and signal weakness to the opposing side.
• Omitting the Insurance Act Deductible: Failing to address the deductible in motor vehicle claims leads to confusion and ineffective negotiation.
• No Deadline: A demand without a deadline is a request, not a demand. It signals that you are not prepared to litigate and invites delay.
• Making Legal Admissions: Be careful that your factual summary does not inadvertently concede elements of the claim or waive rights that may be important later.
• Failing to Preserve the Limitation Period: Never assume that a demand letter tolls the limitation period. It does not, unless there is an express agreement to that effect.
