The issue in this case was whether a tug and barge combination are exempt from the pilotage requirement imposed by the Laurentian Pilotage Authority Regulations passed pursuant to the Pilotage Act. At trial, the judge considered the regulations were "vague and imprecise" and held that both the tug and barge were exempt. On appeal, however, the Court of Appeal held that the trial judge had misread the regulations. The Court of Appeal agreed that the tug was exempt but held that the barge was subject to compulsory pilotage. The Court of Appeal further held that the Laurentian Pilotage Authority was entitled to take the dimensions of the tug into account when setting the pilotage charges for the barge.
