Notes and commentary on recent decisions and developments.
A March 2022 amendment quietly raised the bar for litigants who serve their expert reports late. Where the old rule granted leave almost as of course, the party at fault must now show a reasonable explanation and the absence of uncompensable prejudice or undue delay. Three years of Ontario rulings show the courts taking the change seriously, which makes opposing a late report a tactic well worth considering.
“Justice delayed is justice denied.” Few principles are repeated more often, yet civil cases in Ontario routinely take more than five years to reach trial. The Civil Rules Review, launched by the Attorney General and the Chief Justice, released its Phase 2 Consultation Paper in April 2025 with proposals to make civil proceedings faster, more affordable, and more accessible. A look at what the changes could mean for plaintiffs and defendants alike.
On February 25, 2025, Hudson Chalmers volunteered as a judge at Western Law’s Medical Malpractice Moot Trial, organized by Legate Injury Lawyers and the Western Health Law Association. The hypothetical turned on whether an emergency physician met the standard of care in a delayed stroke diagnosis. He reflects on advocacy, expert evidence, and this year’s exceptionally strong students.
