Mortimer v. Cameron

(1994), 17 O.R. (3d) 1 (C.A.); This case is a leading Canadian authority on “proximate cause” in tort. The Lerners team developed a legal argument on unusual facts to show that the plaintiff’s horseplay on a staircase should not reduce his damages for the quadriplegia he suffered when the staircase wall collapsed and he fell into the street below. Negligence was established against the landlord of the building and the municipality for failing to ensure that building standards were met.
