Starting a new job in Canada often means encountering unfamiliar substances and materials. If your role involves handling or being near hazardous products, understanding the Workplace Hazardous Materials Information System is essential. Canadian law requires employers to provide WHMIS training to every worker who works with or may be exposed to hazardous substances. This article explains what new hires should expect from that training, how often it must be renewed, and where to find reliable certification.
Why WHMIS Training Is Required for New Workers
All Canadian jurisdictions require employers to develop, implement, and maintain a worker WHMIS education and training program. This legal obligation exists to protect workers from the risks posed by hazardous materials in the workplace. New hires who have never received WHMIS training, or who are moving into a job where hazardous substances are present, must complete the required education and site-specific training before they begin work with those materials.
The Legal Requirement and Employer Responsibility
Employers are legally required to provide WHMIS training to anyone who works with or may be exposed to hazardous substances in Canada. This includes new full-time employees, part-time workers, temporary staff, and even volunteers if their duties bring them into contact with hazardous products. The training must cover hazard classes, labels, safety data sheets, and worker responsibilities. Failure to provide this training can result in penalties for the employer and increased safety risks for workers.
WHMIS Education vs. WHMIS Training
It is important to understand the difference between WHMIS education and WHMIS training. Education refers to general, portable information such as how WHMIS works, the different hazard classes, the types of labels, and the purpose of safety data sheets. This knowledge can be applied in any workplace. Training is site-specific and job-specific. It covers the procedures for safely storing, handling, disposing of, and responding to emergencies involving the specific hazardous products used at your workplace. Both education and training are required by law for workers who may be exposed.
What WHMIS Training Covers for New Hires
A complete WHMIS training program for new workers includes several core topics. These are consistent across all provinces and territories, although small variations may exist in specific regulatory details. The following areas are covered in every compliant course:
- The WHMIS system and its legal framework in Canada
- The two main hazard groups and their classes (physical hazards and health hazards)
- The information found on supplier labels and workplace labels
- The purpose and content of safety data sheets (SDS)
- Worker responsibilities and the right to know about hazardous products
- Site-specific procedures for safe storage, handling, disposal, and emergency response
New hires should expect to learn how to read labels, find information on an SDS, and understand the pictograms that indicate hazard types. The training should also explain what to do in case of a spill or accidental exposure at their specific workplace.
How Often Should WHMIS Training Be Refreshed?
WHMIS training does not have a fixed expiration date like some other certifications. Instead, refresher training is required as often as needed to protect worker health and safety. Triggers for retraining include changes in workplace conditions, the introduction of new hazardous products, or when workers change jobs within the same company. If you are a new hire, you will receive initial training, and your employer will schedule updates whenever the hazards in your work area change. Provincial and territorial regulations determine the specific requirements for refresher training.
Does WHMIS Training Transfer Between Employers?
Workers who change employers may need to retake WHMIS training. Because training includes site-specific procedures, a certificate from a previous job may not cover the hazards and protocols of a new workplace. For example, a worker moving from a warehouse role to a laboratory will need new training that addresses the chemicals and handling methods used in the lab. However, the general education component of WHMIS is portable and may not need to be repeated. Employers should assess each new hire’s previous training and provide additional instruction as needed.
Where to Get WHMIS Training in Canada
New hires and employers have several options for completing WHMIS training. Both online and in-person courses are widely accepted, as long as they meet the requirements of the relevant provincial or territorial occupational health and safety legislation.
Free WHMIS Training Options
Workplace Safety and Prevention Services offers a free WHMIS online certification e-course that takes about 1.5 hours to complete. This course includes a printable certificate and meets Ontario’s legal requirements. The availability of this free course for workers outside Ontario is not clearly stated, so individuals in other provinces should verify that the course is accepted by their local regulator before enrolling.
Paid WHMIS Training Providers
Several commercial providers offer paid WHMIS courses. For instance, Canada Safety Training offers a 60-minute online WHMIS certification course for $14.95 CAD. Other providers include whmis.ca, worksitesafety.ca, and the Canadian Centre for Occupational Health and Safety, which offer paid training courses. Organizations like the Canadian Health Care Provider Training Institute also offer online WHMIS certification as part of their workplace safety training offerings. Prices and course lengths vary, so new hires should confirm that the provider’s certificate is accepted by their employer and provincial regulator.
Provincial and Territorial Variations
While the core WHMIS requirements are consistent across Canada, provincial and territorial regulations determine specific education and training requirements. Small variations between jurisdictions may exist, such as differences in the accepted training providers or documentation required. New hires working in multiple provinces or for federally regulated employers should verify that their training meets all applicable rules. Your employer or the local occupational health and safety authority can confirm whether a particular course meets the legal standard for your workplace.
Staying Current with WHMIS Updates
Health Canada periodically updates the list of hazardous substance assessments and supplier regulations. For example, effective March 2025, new assessments were introduced for chemicals such as 1-Methyl-2-pyrrolidone, acetone, cristobalite, ethylene glycol, styrene, and quartz silica. These changes may affect the hazard information on labels and safety data sheets. Employers and workers should stay informed about such updates to ensure that training materials and workplace procedures reflect the most current hazard classifications. Regular refresher training, especially when new substances are introduced, helps maintain compliance and worker safety.
Frequently Asked Questions
Is WHMIS training mandatory for all workers?
No. WHMIS training is mandatory only for workers who work with hazardous products or who may be exposed to them during their job. Workers who never handle or come into contact with hazardous materials are not required to take the training.
How long is WHMIS certification valid?
WHMIS certification does not have a fixed expiry date. Refresher training is required whenever workplace conditions change, new hazardous products are introduced, or workers change jobs. Employers must assess the need for retraining on an ongoing basis.
Do I need separate WHMIS training for different provinces?
In most cases, the core training is similar across provinces, but small variations may exist. If you move to a new job in a different province, your employer may require you to complete additional training that addresses local regulations and site-specific hazards.
What topics are covered in WHMIS training?
Training covers hazard classes, supplier and workplace labels, safety data sheets, and worker responsibilities. It also includes site-specific procedures for safe storage, handling, disposal, and emergency response at your workplace.
Can I take WHMIS training online?
Yes. Online WHMIS training is widely available and accepted by most employers and regulators, provided the course is compliant with Canadian standards. Both free and paid options exist, such as the course from Workplace Safety and Prevention Services and courses from private providers.
