Can I sue my lawyer for a mistake made during a real estate closing in Ontario?
Yes. Real estate lawyers handle closings under tight deadlines with real money and legal title at stake, and mistakes like failing to catch a title defect, mishandling mortgage discharges, misapplying funds on the statement of adjustments, or missing a registration requirement can support a professional negligence claim if they fall below what a reasonably competent real estate lawyer would have caught. As with other professional negligence claims, you need to show the error was a genuine departure from competent practice, that you relied on the lawyer to catch it, and that it caused you a quantifiable loss.
Closing files are usually well-documented, which helps - the reporting letter, title search results, and correspondence with the other side's lawyer and the lender typically show what was actually checked and disclosed. Many closing-related problems surface only when you try to sell or refinance later, so it's worth having a lawyer review the file promptly once an issue is identified, since limitation periods run from when the problem was or reasonably should have been discovered. Ontario lawyers generally carry mandatory professional liability insurance, which is usually the practical source of any recovery.
