About Workplace Health and Safety

In Ontario, your right to a safe and healthy workplace is not just a good idea—it's the law. The cornerstone of this protection is the Occupational Health and Safety Act (OHSA), a comprehensive piece of legislation that outlines the duties of employers, supervisors, and workers. The OHSA is built on the principle of the 'internal responsibility system,' which means that everyone in the workplace has a role to play in ensuring safety. Employers have the primary duty to take every precaution reasonable in the circumstances to protect a worker. This includes providing information and instruction about hazards, ensuring equipment is in good condition, and maintaining safe work environments.

For workers, the OHSA grants three fundamental rights. First is the 'Right to Know' about any potential hazards you may face on the job. Second is the 'Right to Participate' in the health and safety process, often through a workplace Joint Health and Safety Committee (JHSC). Third, and perhaps most critically, is the 'Right to Refuse' work that you believe is unsafe for you or a coworker. This right is protected, and an employer cannot legally discipline, fire, or otherwise penalize you for exercising it in good faith. This is known as a 'reprisal,' and it is strictly prohibited.

It's important to understand that 'health and safety' under the OHSA extends beyond physical dangers like faulty machinery or chemical exposure. It also explicitly includes workplace violence and harassment, which are considered workplace hazards. Employers are legally required to have policies and programs in place to address these issues. If you find yourself in a situation where your safety concerns are being ignored, leading to significant negative changes in your job or even dismissal, the circumstances can become quite complex, potentially involving multiple areas of employment law. Understanding your specific rights and the correct procedures to follow is crucial, and reviewing your unique situation with a legal professional can provide essential clarity.

Frequently Asked Questions

What is the main law that protects my health and safety at work in Ontario?

The primary law is the Occupational Health and Safety Act (OHSA). It sets out the rights and duties of all parties in the workplace to ensure a safe environment.

What should I do first if I believe my work is unsafe?

You should immediately report your concern to your supervisor or employer. If the issue is not resolved and you still believe the work is unsafe, you have the right to refuse work by following the specific process outlined in the OHSA.

Can my boss fire me for reporting a safety issue or refusing unsafe work?

No. The OHSA prohibits employers from carrying out a 'reprisal' against a worker for following the law. This means they cannot dismiss, discipline, intimidate, or penalize you for exercising your health and safety rights.

Does workplace health and safety cover issues like bullying or psychological stress?

Yes, to an extent. The OHSA defines workplace harassment, which can include bullying, as a workplace hazard. Employers are required to develop and maintain programs to address it, which contributes to psychological safety.

Is there a time limit to file a complaint if I'm punished for raising a safety concern?

Yes, there are strict deadlines. If you believe you have been subject to a reprisal, you must file a complaint with the Ontario Labour Relations Board. Seeking legal advice quickly is important to ensure you don't miss these critical timelines.

What is a Joint Health and Safety Committee (JHSC)?

A JHSC is a committee of worker and management representatives who meet regularly to identify workplace hazards and make recommendations for improvement. In Ontario, most workplaces with 20 or more employees are required to have one.

My employer ignores all safety rules and I'm worried I'll be fired if I speak up. When is it time to get legal advice?

If you are in a situation where raising legitimate safety concerns puts your job at risk, or if you have already faced negative consequences, it's a critical time to consult with an employment lawyer. They can advise you on how to exercise your right to refuse unsafe work and protect yourself from illegal reprisals.

Common Scenarios

  • A warehouse worker is asked to operate a forklift that has not been properly maintained and has faulty brakes.
  • An office administrator is subjected to persistent verbal abuse from a manager, causing significant anxiety, but their complaints to HR are dismissed.
  • A roofer is told to work without proper fall protection equipment on a high-pitched roof, directly violating OHSA regulations.
  • After a retail employee reports a recurring electrical hazard to their supervisor, their hours are suddenly and drastically cut without explanation.
  • A lab technician is not given adequate training or personal protective equipment (PPE) before being instructed to handle a new, potentially hazardous substance.

What You Should Know

  • Document every safety concern in writing. Keep a personal record of dates, times, the specific hazard, who you reported it to, and their exact response.
  • Familiarize yourself with the formal work refusal process under the OHSA. Following the correct steps is essential to protect your rights and your job.
  • Do not quit your job in response to an unsafe condition without first attempting a work refusal and seeking legal advice, as resigning can affect your legal options.
  • If you have been disciplined or terminated after raising a health and safety issue, contact an employment lawyer immediately to assess whether you have grounds for a reprisal complaint.
  • Know who your Joint Health and Safety Committee (JHSC) representatives are. They can be a valuable resource for raising concerns and promoting a safer workplace.
