The appellant, a federally-regulated Crown corporation, appealed a Federal Court of Appeal decision reinstating a Health and Safety Officer's direction that the employer had contravened s. 125(1)(z.12) of the Canada Labour Code by failing to ensure that workplace safety inspections covered letter carrier routes and points of call beyond the physical depot building.
The appeals officer had concluded that the statutory inspection obligation applied only to workplaces the employer physically controls, and the Federal Court upheld that decision.
The majority of the Supreme Court applied the Vavilov framework for reasonableness review and held that the appeals officer's interpretation — confining the inspection duty to employer-controlled premises — was reasonable, internally coherent, and defensible in light of the text, context and purpose of the provision.
The appeal was allowed and the appeals officer's order was restored.
