Health & Safety Made Simple: Practical Tips for Every Workplace

ONTARIO HEALTH AND SAFETY FAQs

Your Health & Safety Questions, Answered.

What are my health and safety rights as a worker in Ontario?

Under Ontario’s Occupational Health and Safety Act (OHSA), workers have key rights:

  • Right to Refuse Unsafe Work: You can refuse tasks you reasonably believe are dangerous, and it is illegal for your employer to penalize you for doing so.
  • Right to Know: You must be informed about workplace hazards.
  • Right to Participate: You can contribute to safety discussions and represent health and safety concerns.
What responsibilities do employers and supervisors have under OHSA?

Employers must:

  • Keep the workplace safe and properly maintained
  • Provide hazard information, training, safety equipment, and competent supervision.
  • Post mandatory materials such as the OHSA and the WSIB “In Case of Injury” poster.
  • Establish a health and safety committee (JHSC) if they have 20+ employees, or a safety representative if they have 6–19 employees
  • Supervisors must ensure work is assigned and carried out safely and inform employees of hazards.
What is the Internal Responsibility System (IRS)?

The Internal Responsibility System (IRS) emphasizes that everyone in the workplace—from workers to supervisors to employers—shares responsibility for health and safety. Clear roles, communication, and mutual accountability are the foundation of the IRS.

What are Joint Health and Safety Committees (JHSC) and when are they required?

In workplaces with 20 or more employees, a Joint Health and Safety Committee (JHSC) must be established, with at least one worker and one management representative, both of whom must be certified. The JHSC conducts inspections, provides hazard recommendations, and promotes overall health and safety.
For workplaces with 6–19 employees, a Health and Safety Representative must be appointed to inspect and raise health and safety issues.

What training is required for workers in Ontario?

Ontario mandates several key trainings, including:

  • In the construction industry, Working at Heights (Fall Protection) training is also mandatory, including refresher training as needed.
  • Worker and Supervisor Health & Safety Awareness training under OHSA.
  • WHMIS (Workplace Hazardous Materials Information System) training—refreshed at least annually.
  • Workplace Violence & Harassment training.
What are two requirements that you have to follow under the Occupational Health and Safety Act (OHSA)?

Under Ontario’s Occupational Health and Safety Act (OHSA), both employers and workers have legal duties designed to keep workplaces safe. Two key requirements include:

  1. The Employer’s Duty to Provide a Safe Workplace
    Employers must take every reasonable precaution to protect the health and safety of workers. This includes providing proper training, maintaining equipment, ensuring protective gear is available, and addressing hazards promptly.
  2. The Worker’s Duty to Work Safely
    Workers must follow safe work practices and use the protective equipment provided. They are also required to report hazards or violations to their supervisor or employer so risks can be controlled.

Together, these duties create a shared responsibility between employers and employees to prevent injuries and promote a culture of safety.

What are three main reasons for managing health and safety?

There are three core reasons why businesses should actively manage health and safety in the workplace:

  1. Legal Responsibility
    In Ontario, employers are legally required under the Occupational Health and Safety Act (OHSA) to protect workers from hazards. Failing to comply can result in fines, penalties, or even prosecution.
  2. Financial Benefits
    Workplace injuries and illnesses can be costly. Lost productivity, WSIB claims, equipment damage, and training replacement staff all add up. Managing health and safety helps reduce these costs and keeps operations running smoothly.
  3. Moral Duty
    Every worker deserves to go home safe and healthy at the end of the day. Proactively managing health and safety shows respect for employees, builds trust, and strengthens workplace culture.

By focusing on these three areas—legal, financial, and moral—businesses not only stay compliant but also create safer, more productive workplaces..

What are the five steps to managing health and safety?

Effective health and safety management follows five key steps:

  1. Policy
    Develop a clear health and safety policy that outlines your company’s commitment to protecting workers and meeting legal obligations.
  2. Organizing
    Assign roles and responsibilities so everyone—employers, supervisors, and workers—understands their duties under the Occupational Health and Safety Act (OHSA).
  3. Planning and Implementing
    Identify hazards, assess risks, and put controls in place. Provide training, equipment, and safe work procedures to protect workers.
  4. Measuring Performance
    Regularly inspect, audit, and track safety performance to ensure controls are working and standards are being met.
  5. Reviewing and Improving
    Evaluate the overall system, learn from incidents or near misses, and make improvements to strengthen workplace safety.

Following these five steps creates a cycle of continuous improvement, helping Ontario businesses stay compliant, reduce costs, and keep workers safe.

What is a critical injury?

In Ontario, a critical injury is defined under Regulation 834 of the Occupational Health and Safety Act (OHSA). It refers to a serious injury that results in one or more of the following:

  • An injury of a serious nature that places life in jeopardy.
  • Produces unconsciousness.
  • Results in a substantial loss of blood.
  • Involves the fracture of a leg or arm, but not a finger or toe.
  • Involves the amputation of a leg, arm, hand, or foot, but not a finger or toe.
  • Consists of burns to a major portion of the body.
  • Causes the loss of sight in one eye.

When a critical injury occurs in the workplace, the employer must immediately report it to the Ministry of Labour, Immigration, Training and Skills Development (MLITSD), the Joint Health and Safety Committee (or health and safety representative), and the union (if applicable).

This definition ensures that the most serious incidents are reported quickly so they can be investigated, and corrective actions can be taken to prevent future harm.

What is a JSA/JHA in safety?

A JSA, or Job Safety Analysis, is a step-by-step process used to identify hazards and determine safe work procedures for a specific job or task. It is sometimes called a Job Hazard Analysis (JHA).

The purpose of a JSA/JHA is to:

  • Break down a job into tasks to understand how the work is done.
  • Identify potential hazards associated with each step.
  • Develop control measures such as training, protective equipment, or safer work methods to eliminate or reduce risks.

JSAs/JHAs are valuable because they:

  • Help prevent workplace incidents by addressing hazards before work begins.
  • Provide a training tool for new employees.
  • Support compliance with the Occupational Health and Safety Act (OHSA) in Ontario by showing due diligence.

In short, a JSA/JHA is a proactive safety tool that improves awareness, reduces risk, and ensures safer work practices.

When do I need a health and safety program?

In Ontario, whether you need a health and safety program depends on the size of your workforce:

  • 5 to 19 workers → You are required to have a written health and safety policy and to develop and maintain a program to implement that policy.
  • 20 or more workers → In addition to a policy and program, you must also establish a Joint Health and Safety Committee (JHSC).
  • Fewer than 5 workers → A formal program is not legally required, but you still have a duty under the Occupational Health and Safety Act (OHSA) to take every reasonable precaution to protect your workers.

A health and safety program typically includes:

  • Safe work procedures
  • Worker training and orientation
  • Hazard identification and control
  • Emergency preparedness
  • Workplace inspections and incident reporting

Even if you are not legally required to have a program, many small businesses choose to create one. Doing so demonstrates due diligence, helps prevent injuries, and can reduce costs related to fines, lost time, or WSIB claims.
