Question: If one company's employees are performing work on the property of another business alongside employees of the other business, who is responsible for the occupational health and safety of the employees?

Answer: As an example, Alberta's provincial occupational health and safety legislation is comprised of the Occupational Health and Safety Act (OHSA), the Occupational Health and Safety Code, 2009 (the OHS Code), and the Occupational Health and Safety Regulation (the OHSR).

Pursuant to the OHSA, employers are responsible for the health and safety of workers engaged in the work of that employer, and workers not engaged in the work of that employer but present at the work site at which that work is being carried out. This means that, in general, an employer is responsible for the health and safety of any workers engaged in work on or in its work site, regardless of whether or not they are employed by that specific employer.
