Everything You Need to Know About WHMIS 2015 in Ontario

In 2023, the WSIB allowed 7,862 injury claims from exposure to caustic, noxious, or allergenic substances. That doesn't include claims that were submitted and denied, or incidents that were not reported to the WSIB. That's 21.5 chemical injuries per day in Ontario workplaces.


WHMIS stands for Workplace Hazardous Materials Information System and is Canada's hazard communication standard for the handling and use of hazardous workplace materials. WHMIS is legislated federally, provincially and territorially in Nunavut and Northwest Territories and Yukon, and all workers must receive WHMIS training.


The original WHMIS requirements are generally referred to as WHMIS 1988 and the new ones are called WHMIS 2015. The transition to WHMIS 2015 formally ended on December 1, 2018. You may hear it referred to as WHMIS or WHMIS 2015.


What is WHMIS?

WHMIS is a comprehensive system designed to provide workers with important information about hazardous materials that they may encounter in their workplaces. Initially introduced in 1988, WHMIS is continuously updated to stay in line with new safety protocols and international standards, including the most recent alignment with the Globally Harmonized System of Classification and Labelling of Chemicals or GHS.


The goal of WHMIS is to ensure that workers have the right knowledge to understand, recognize, and mitigate risks associated with hazardous materials they may come in contact with at work, thus fostering safer workplaces across industries.


In provincially-regulated Ontario workplaces, WHMIS is enforced by the Ministry of Labour, Immigration, Training and Skills Development (MLITSD).



What Does WHMIS Training Involve?

WHMIS training is a requirement for all provincially-regulated Ontario workplaces where workers may be exposed to hazardous materials as part of their job. The training typically covers the following key components:

  1. Labels – Workers will learn how to read and understand supplier labels and workplace labels on hazardous materials. These labels include important symbols, signal words, and precautionary statements that describe the chemical's hazards.

  2. Safety Data Sheets (SDS) – Employees will learn how to access and interpret the detailed safety data sheets that accompany hazardous substances. SDSs provide in-depth information about handling, storing, and responding to emergencies related to the material.

  3. Hazardous Materials Classification – Workers will learn to identify the types of hazards that materials can pose. These can include physical hazards (e.g., flammability, explosiveness) and health hazards (e.g., toxicity, carcinogenicity).

  4. Personal Protective Equipment (PPE) – WHMIS training includes guidance on appropriate personal protective equipment, such as gloves, masks, and goggles, to ensure that workers are properly protected from hazardous materials.

  5. Safe Handling and Disposal Procedures – Training will also cover the correct methods for handling and disposing of hazardous substances in a safe and environmentally friendly manner.

  6. Workplace-Specific Training – WHMIS training must cover the above general knowledge as well as workplace-specific information. This section must train employees on specific hazardous materials that they will encounter in their workplace. The training must be relevant to the types of materials employees handle on the job.

Why is WHMIS Training Important in Ontario?

  1. Legal Requirement – In Ontario, WHMIS training is required by law under the Occupational Health and Safety Act and Workplace Hazardous Materials Information System Regulation, made under the Act. Employers must ensure that workers receive proper education about hazardous materials they may encounter. Failure to comply with this legal requirement could result in penalties and fines for the employer from the MLITSD, as well as increased risks to worker health and safety.

  2. Health and Safety – WHMIS training is vital for the protection of workers. Exposure to hazardous chemicals can lead to serious health risks, including respiratory issues, skin irritation, poisoning, and even long-term conditions like cancer. By ensuring workers understand the risks and how to minimize hazardous exposure, WHMIS training contributes significantly to the overall health and safety of the workforce.

  3. Prevention of Workplace Incidents – Understanding how to identify hazards and mitigate risks associated with hazardous materials can help prevent accidents and injuries. Whether it’s a chemical spill, fire, or improper handling of a toxic substance, WHMIS training helps workers how to act in preventing or responding to workplace emergencies.

  4. Promotes a Safety Culture – When workers are properly trained, they are more likely to take personal responsibility for their own safety and the safety of their colleagues. This leads to a stronger safety culture within the organization, where workers actively engage in safe practices and are more aware of the risks around them.

  5. Business Continuity – By reducing workplace accidents and improving safety, WHMIS training ensures that your business can continue operating smoothly without the disruptions and costs associated with accidents, injuries, and MLITSD orders. It also demonstrates to customers and stakeholders that the business prioritizes safety and compliance.
