Notes on insurance, subrogation and civil litigation.
Jim Davidson has been named a 2027 Lawyer of the Year for Personal Injury Litigation in Toronto, and nine Davidson Cahill Morrison LLP lawyers are recognized in The Best Lawyers in Canada and Best Lawyers: Ones to Watch in Canada. The recognitions span insurance law, medical negligence, and personal injury litigation, and are decided entirely by peer review.
In most civil litigation expert evidence supports the case. In medical negligence it very largely constitutes it, which means the decisions determining the outcome are made at the report stage rather than in the courtroom. Paul Cahill presents Expert Reports: Selection and Strategy at Osgoode Professional Development on October 1, 2026.
A leased Honda Civic was in an accident in August 2020. It first appeared on a monthly fleet report a month later, and had been leased since 2017 without ever making the schedule of automobiles. In 2026 ONCA 553, the Court of Appeal held that OPCF 21A (c) means what its capital letters say: no coverage until a request for coverage is filed, and no coverage backdated to policy inception. Chris Morrison and Kathleen Lefebvre were counsel for the successful appellant.
