2026 Car Insurance Reform Update — Ontario

Ontario's most significant auto insurance reform in two decades takes effect July 1, 2026: the new Statutory Accident Benefits Schedule allows drivers to select benefit levels a-la-carte rather than purchasing the standard package. For high-premium drivers this can reduce premiums by 5–15%, but inadequate benefit selection creates coverage gaps. Work with a licensed Ontario broker to model the correct selection for your situation before the next renewal.
