A regional logistics and warehousing company operating distribution centres in 3 provinces received a written notice from a provincial occupational health and safety regulator indicating that an inspector would attend one of its facilities within 48 hours to investigate a formal complaint. The complaint had been filed by a warehouse worker who alleged that management had pressured employees to continue operating a malfunctioning conveyor system despite visible mechanical defects and that a supervisor had threatened disciplinary action when the worker raised concerns about the equipment's safety. The company, which employs approximately 280 workers across its provincial warehouse operations and another 45 drivers engaged in interprovincial trucking, had not previously faced a regulatory investigation of this nature.

The warehouse where the complaint originated had been operating for 7 years under provincial jurisdiction, though the company's interprovincial trucking division fell under federal regulation pursuant to Part II of the Canada Labour Code. This dual-jurisdictional structure had created internal confusion about which safety requirements applied to which workers, and the company had historically applied a single set of safety policies across all operations without distinguishing between the 2 regulatory regimes. The facility employed 94 workers on rotating shifts and had established a joint health and safety committee 4 years earlier, though the committee had met only sporadically over the preceding 18 months and had not conducted a formal workplace inspection in nearly a year.

The worker who filed the complaint had been employed at the facility for 3 years and had previously raised safety concerns through informal channels without resolution. When the conveyor system developed a recurring jam 6 weeks earlier, the worker had verbally refused to clear the obstruction while the system remained powered, citing the risk of entanglement. A shift supervisor had responded by assigning another worker to the task and had later documented the refusal as insubordination in the complaining worker's personnel file. The conveyor malfunction was eventually addressed through a temporary repair, but no formal hazard assessment had been completed and no report had been filed with the joint health and safety committee.

The company's ownership structure included 3 directors who held equal shares and who collectively made major operational and financial decisions, including those affecting workplace safety investments. The directors had delegated day-to-day safety management to a human resources manager who lacked formal training in occupational health and safety compliance and who reported to the directors on a quarterly basis. With the inspector's visit imminent, the company faced questions about its obligations under the applicable regulatory framework, the adequacy of its internal safety structures, and the potential consequences of the investigation for the organization and its leadership.

The OHS Framework in Canada: Federal and Provincial Jurisdiction

Occupational health and safety law in Canada operates through a framework that divides responsibility between the federal government and the provinces and territories, creating a complex but navigable system that every employer must understand to meet their legal obligations. This division of powers flows directly from the Constitution Act, 1867, which allocated jurisdiction over employment matters primarily to the provinces while reserving certain industries and undertakings for federal oversight. The result is that approximately ninety percent of Canadian workers fall under provincial or territorial jurisdiction, while the remaining ten percent work in federally regulated industries governed by Part II of the Canada Labour Code. For human resources professionals, business owners, and people managers, understanding which jurisdiction governs their workplace is not merely an academic exercise but rather the essential first step in building a compliant and effective occupational health and safety program.

The constitutional framework that shapes Canadian employment law reflects the historical compromise that created Confederation, though the specific application to occupational health and safety has evolved substantially over the past century. Provincial jurisdiction over employment matters derives from the provinces' authority over property and civil rights within their boundaries, which courts have interpreted broadly to include the regulation of employment relationships and workplace conditions. Federal jurisdiction, by contrast, extends to specific industries that are national or interprovincial in character, including banking, telecommunications, broadcasting, interprovincial and international transportation, postal services, nuclear energy, and certain Crown corporations. The practical consequence of this division is that a trucking company operating routes between Calgary and Vancouver falls under federal jurisdiction, while a trucking company operating solely within British Columbia falls under provincial jurisdiction, even though both companies might operate out of the same industrial park and employ workers performing nearly identical tasks.
