Is a demand letter from a lawyer more effective than one I write myself in Ontario?

A demand letter from a lawyer typically carries more weight than one written by the claimant personally, and for several reasons. The recipient understands that a lawyer-authored letter means professional legal counsel is already engaged, that the claims have been reviewed for legal merit, and that the sender is more likely to follow through with court proceedings.

A self-written letter can be effective, particularly for clear-cut debts or simple disputes. However, if the letter contains legal errors, overstates or understates your claim, or uses language that could be seen as threatening or defamatory, it may actually hurt your position. A lawyer will draft the letter to accurately reflect your entitlement under Ontario law, avoid statements that could damage your case, and set the right tone.

For larger or more complex disputes — commercial contracts, professional negligence, significant property damage — a lawyer-drafted letter also signals to the other side that you have assessed your legal position carefully. This can accelerate settlement discussions. Costs for a demand letter are often modest relative to the amount at stake and may be recoverable as part of your claim if the matter proceeds to court. Speaking with a lawyer about your dispute is a good starting point.
