Occupational Health and Safety Act: Everything You Need To Know

It’s vital for small business owners in Ontario to be informed about the province’s Occupational Health and Safety Act (OHSA) to ensure workplace safety. SMEs actually have a legal obligation to abide by these regulations and actively keep their employees informed and supervised to guarantee that the expectations of the act are being met. OHSA was established and has been enforced by the Ontario Ministry of Labour. This legal framework provides small businesses with procedures to avoid everything from hazardous chemicals to preventing sexual harassment in the workplace.
