A worker starts a new job at a manufacturing plant. Before touching any equipment, they are told they need WHMIS training.

Another employee at a small auto shop is asked to pay for their own certification. A contractor wonders if their old certificate still counts. These situations play out daily across Canada, and the confusion is understandable.

With different rules between provinces and ongoing updates to the legislation, many workers and employers ask the same questions: is WHMIS training mandatory, and who pays for it?

This guide provides clear, legally grounded answers to both questions.

Quick Answer Box

What Is WHMIS?

WHMIS stands for the Workplace Hazardous Materials Information System. It is Canada's national hazard communication standard for chemical use and exposure in the workplace. The system includes:

1. Hazard classification and product classification

2. Container labelling requirements

3. Safety Data Sheets (SDSs)

4. Worker education and training programs

WHMIS was created in 1988 to ensure workers have the information they need to safely use hazardous products on the job. It was updated in 2015 to align with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), becoming known as WHMIS 2015. Further updates in 2023 have streamlined the system, which is now referred to simply as WHMIS.

The system is implemented through coordinated federal, provincial, and territorial legislation, making it a truly national program that applies across Canada.

Is WHMIS Training Mandatory in Canada?

Yes, WHMIS training is legally required across Canada. All Canadian jurisdictions require that employers develop, implement, and maintain a worker education program that enables workers to work safely with hazardous chemicals.

The requirement applies whenever a workplace has hazardous products present. Under the Occupational Health and Safety Act and related regulations in each province, employers must ensure workers are trained before they are exposed to or likely to handle, store, use, clean, or dispose of hazardous products.

What Does the Law Say?

The legal foundation for WHMIS training comes from several sources:

1. Federal legislation: The Hazardous Products Act and Hazardous Products Regulations set out supplier requirements for labelling and Safety Data Sheets.

2. Provincial/territorial legislation: Each jurisdiction has incorporated WHMIS requirements into their occupational health and safety laws.

3. Canada Labour Code: For federally regulated workplaces, the Code requires training adapted to workers' needs.

The key point is simple: if hazardous products are present, WHMIS training is not optional. Failure to provide training can result in warning letters, penalties, reputation loss, and even operational shutdowns.

Who Needs WHMIS Training?

WHMIS training is required for anyone who may be exposed to hazardous products in their work. This includes:

1. Workers who handle, use, store, or dispose of hazardous products

2. Workers who may be exposed during their daily work activities

3. Supervisors and managers of workers who may be exposed

4. Emergency response workers

5. Laboratory personnel

6. Maintenance staff who work in areas where hazardous products are present

7. Cleaners who use chemical products

8. Construction workers

9. Healthcare staff

10. Paid and unpaid student interns working with hazardous materials

Who Does Not Need Training?

Office workers who have no exposure to hazardous products typically do not require WHMIS training. However, if an office worker might enter areas where hazardous products are used, or if they handle products like cleaning supplies, training becomes necessary.

The Two Types of WHMIS Training

Understanding that WHMIS training has two distinct components is essential for compliance.

General WHMIS Education

This component covers the general information about how WHMIS works. It includes:

1. Hazard classes and pictograms

2. Label requirements and interpretation

3. Safety Data Sheets (SDSs): purpose, content, and location

4. Regulatory overview

5. General safety information

General education can be delivered through online courses, classroom instruction, or self-study materials. Many organizations use certified online providers for this portion.

Site-Specific and Job-Specific Training

This is the most critical part of WHMIS training. It addresses the actual hazards and procedures in your specific workplace:

1. Procedures for safe storage, handling, use, and disposal of hazardous products used in your facility

2. Emergency procedures for spills, releases, or exposures

3. Location of SDSs and how to access them in your workplace

4. Specific hazards of products you work with

5. Required personal protective equipment for your tasks

Supervisors must provide this workplace-specific training and document that it has occurred. Even if a worker has taken a general WHMIS course elsewhere, they still need site-specific training from their employer.

Who Is Responsible for Providing WHMIS Training?

Canadian occupational health and safety law places primary responsibility for WHMIS training on employers. This is a critical point for understanding who pays and who arranges training.

Employer Duties

1. Developing, implementing, and maintaining a WHMIS education and training program

2. Ensuring all workers at risk of exposure receive product-specific training

3. Providing all necessary hazard information from suppliers

4. Ensuring hazardous products are properly labelled

5. Making Safety Data Sheets available and accessible to workers

6. Consulting with health and safety representatives when developing or reviewing training programs

7. Reviewing and updating training programs at least annually or whenever conditions change

When Training Must Be Updated

Training programs must be reviewed and updated whenever:

1. Working conditions, processes, or hazard information change

2. New hazardous products are introduced

3. New hazard information becomes available

4. New safety or handling information emerges

Employee Responsibilities

The responsibilities of the employees mainly include:

1. Participating in training

2. Following safety procedures

3. Asking questions if the process or any training component is unclear

Does WHMIS Training Have to Be Paid?

This is one of the most common questions, and the answer is clearly defined under Canadian law.

The Legal Requirement: Employers' Pay

Yes, when WHMIS training is required for the job, employers must pay for it. This includes both the cost of the training itself and compensation for the time spent taking it.

Legal sources confirm this obligation:

1. A collective agreement sample clause explicitly states: "The Employer will cover the course fees, registration, wages, and expenses at applicable rates" for required safety training.

2. Employers are legally required to provide instruction and training to ensure workers can work safely.

3. The employer has the general responsibility to provide all hazard information possible.

What "Paid" Includes

When training is mandatory, employer payment obligations typically cover:

1. Course registration fees

2. Wages for time spent in training (during work hours)

3. Replacement of regular wages if training occurs outside normal hours

4. Materials and supplies needed for training

5. Travel expenses, if applicable

When Workers Might Pay Themselves

There are limited situations where workers might personally pay for WHMIS training:

1. Pre-employment certification: Job seekers may choose to take WHMIS training to improve their resumes before being hired.

2. Freelancers or independent contractors: Self-employed individuals may need to arrange their own training.

3. Workers seeking certification outside employer requirements: If an employee wants a certificate for personal reasons not required by their job.

However, once employed in a position that requires WHMIS training, the employer cannot require the worker to pay for mandatory training.

Is WHMIS Required in Every Province?

Yes, WHMIS is required in every province and territory. However, specific implementation details vary by jurisdiction because occupational health and safety is enforced provincially.

Language Requirements

Some jurisdictions have specific language requirements for training. Seven jurisdictions address language in OHS laws: federal, BC, MB, ON, QC, SK, and YK.

The Canada Labour Code requires training to be adapted to a worker's "special need," which may include language considerations. Employers should ensure training is accessible and understandable to all workers.

Does WHMIS Training Expire or Need Renewal?

WHMIS legislation does not specify a uniform expiry date for training certificates. However, this does not mean training lasts forever.

When Training Must Be Refreshed

Training must be updated when:

1. Job duties change

2. New hazardous products are introduced

3. Work processes change

4. New hazard information becomes available

5. Regulations are updated (like the 2023 amendments)

Best Practices and Organizational Requirements

While the law doesn't set an expiry date, many organizations and training providers establish renewal periods:

1. Many employers require refresher training annually as a best practice

2. Some institutions set 3-year renewal periods

3. Training should be reviewed at least annually for program effectiveness

The WHMIS 2025 Deadline

Health Canada's amendments to the Hazardous Products Regulations came into effect on December 15, 2022. These changes align with the 7th revised edition of the GHS. A three-year transition period ends on December 14, 2025. If your workplace hasn't updated training to reflect these changes, you must do so before this deadline.

Is Online WHMIS Training Accepted?

Yes, online WHMIS training is widely accepted for the general education component of WHMIS.

What Online Training Covers

Online courses typically provide the general WHMIS education component, including:

1. Hazard classification and pictograms

2. Label requirements

3. Safety Data Sheets

4. Regulatory overview

Many online providers offer certificates upon completion.

What Online Training Cannot Replace

Online training alone is NOT sufficient for full compliance. Employers must still provide:

1. Site-specific training on actual products and procedures in your workplace

2. Hands-on instruction for equipment and processes

3. Emergency procedures specific to your facility

The University of Saskatchewan emphasizes: "Site-specific training is the most important part of WHMIS training. Supervisors must provide workers with training on the specific hazardous materials you will be working with".

Choosing an Online Provider

When selecting online WHMIS training, consider:

1. Is the content up to date with current regulations?

2. Does it cover the 2023 amendments and prepare for the 2025 deadline?

3. Will your employer accept this specific certificate?

4. Is the training provider reputable?

Free vs Paid WHMIS Training

Employer Note: When choosing training for your workplace, select programs that meet legal requirements and adequately prepare workers, not simply the lowest-cost option.

What Happens If an Employer Doesn't Provide WHMIS Training?

Failure to provide required WHMIS training carries serious consequences:

1. Warning letters from regulatory authorities

2. Seizure, detention, or removal of hazardous products from the workplace

3. Penalties and fines (amounts vary by jurisdiction)

4. Reputation loss affecting business relationships

5. Operational shutdown orders

6. Liability in case of workplace incidents

7. Workers' compensation claims and potential lawsuits

Additionally, workers have the right to refuse unsafe work if they have not received adequate training on hazardous products.

How to Get WHMIS Certified: Step-by-Step

Step 1: Confirm Requirement

Determine if your job requires WHMIS training based on potential exposure to hazardous products.

Step 2: Complete General Training

Take an approved WHMIS general education course. This can be:

1. Online through a certified provider

2. In-person through classroom instruction

3. Employer-provided training materials

Step 3: Pass the Assessment

Most courses include a test to verify understanding. Passing scores typically range from 70% to 80%.

Step 4: Receive Certificate

Upon successful completion, you will receive a WHMIS certificate or record of training. While certificates are not legally required, they provide proof of training for employers and inspectors.

Step 5: Employer Provides Site-Specific Training

Your employer or supervisor must provide training on the specific hazardous products, procedures, and emergency responses in your actual workplace.

Step 6: Maintain and Update Records

Keep your certificate and ensure you receive updates when conditions change or when refresher training is due.

Frequently Asked Questions

Is WHMIS certification required by law?

No, the law does not require a formal "certificate." However, employers must ensure workers receive both general education and site-specific training. Certificates are useful proof of training, but do not alone fulfill employer obligations.

Can my employer make me pay for WHMIS training?

Generally no. If WHMIS training is required for your job, the employer must provide and pay for it, including compensating your time.

Is WHMIS required for all employees?

No, only for those who work with, handle, store, dispose of, or may be exposed to hazardous products.

Can I take WHMIS online?

Yes, online courses are acceptable for the general education component. However, employers must still provide site-specific training.

How long is a WHMIS certificate valid?

There is no national expiry date. Training must be updated when job duties, products, or processes change. Many employers and institutions set 3-year renewal periods.

Is WHMIS training transferable between jobs?

Generic WHMIS education is transferable, but site-specific training is not. Each employer must provide training on their specific hazardous products and procedures.

What happens if I work without WHMIS training?

If your job involves hazardous products and you lack training, you and your employer are non-compliant with safety laws. You may be unable to perform your duties safely, and your employer faces potential penalties.

Do students and unpaid interns need WHMIS training?

Yes. The law requires mandatory WHMIS training for both paid and unpaid workers, including student interns in research placements, practicums, and thesis-related activity.

Key Takeaways

1. WHMIS training is legally mandatory in Canada for any worker exposed to hazardous products.

2. Employers must provide and pay for required training, including covering time spent training.

3. Training has two components: general education (can be online) and site-specific training (must be provided by employer).

4. No fixed national expiry date, but training must be updated when conditions change. Many organizations use 3-year renewal periods.
