The Supreme Court of Canada will hear four appeals this week. …A tree faller was fatally struck by a rotting tree while working within the area of a forest licence held by West Fraser Mills Ltd. West Fraser was the owner of the workplace, as defined by the Workers Compensation Act. The faller’s employer worked for an independent contractor. The Workers’ Compensation Board conducted an investigation and imposed an administrative penalty on West Fraser. On appeal to the Workers’ Compensation Appeal Tribunal, West Fraser argued that s. 26.2 of B.C.’s Occupational Health and Safety Regulation is ultra vires, and that an administrative penalty can only be levied against a person who has, in the course of acting as an employer, committed a violation.
