This is an English translation of the judgment of Cannon J in the Supreme Court of Canada decision of Montreal Tramways Co. v. Léveillé [1933] S.C.R. 456, a seminal decision on liability for antenatal torts. The English translation was prepared by the parties in the Supreme Court of Victoria decision of Watt v Rama [1972] VR 353 (see 357 for a summary). The full translation was located at the request of a student of mine in 2011 by the Registry of the Supreme Court of Victoria, and is made available here for general interest of scholars researching this area.
