WHMIS Employer Responsibilities: Building a Compliant Program

Under WHMIS, employers carry three core duties: educate and train workers, make sure hazardous products are properly labelled, and keep safety data sheets accessible — plus reviewing the program regularly. Those duties come from WHMIS legislation in every province and territory. Here is each duty in practice, what a compliant program includes, and which products are exempt.

Duty 1 — Educate and train workers

WHMIS splits worker learning into two parts, and employers owe both. Education is the generic, portable knowledge — what WHMIS is, what the pictograms mean, how to read a supplier label and a safety data sheet. It applies in any workplace and travels with the worker between jobs. Training is site-specific: the procedures for the actual products used here, covering storage, handling, use, disposal, spills and emergencies. 1

An online course can cover the general education component, but it does not transfer the legal obligation: the employer remains responsible for confirming that the education provided is adequate, and for delivering the site-specific training itself. An inspector will ask about both, and will ask the employer, not the provider.

Who must receive it: anyone who works with, or may be exposed to, a hazardous product — the exposure test the pillar's who-needs-training section walks through, and it reaches supervisors and emergency responders too.

What "trained" means in practice is a four-question test. For every hazardous product they work with, a worker should be able to say: what are the hazards of this product, how do I protect myself, what do I do in an emergency, and where do I get further information? If a worker cannot answer those four questions on the floor, the program has not worked — regardless of what the training records say.

Duty 2 — Ensure hazardous products are properly labelled

Employers do not write supplier labels — but they are responsible for what is on the shelf. Three obligations follow. Check that incoming products carry a compliant supplier label and that it is legible: a product that arrives unlabelled, or with an English-only label from a US supplier, should not go into service.

Create workplace labels whenever a product is decanted into another container, produced on site, or arrives with a label that has been lost or damaged. Replace labels that degrade — solvent splash and abrasion wear labels out long before the product runs out, and an unreadable label fails the requirement just as a missing one does.

An employer that imports products directly, or produces hazardous products on site, takes on supplier-side duties too — the detail sits with the supplier, importer and employer duties under the amended rules.

Duty 3 — Keep safety data sheets accessible

"Accessible" has a specific meaning: a worker must be able to consult the safety data sheet for any product they work with at any time during their shift, without asking permission and without waiting for someone with a key. A binder in a locked office fails. A binder on the wall by the storage area passes. 1

Digital SDS systems are explicitly permitted, with three conditions: every worker has access to a working device and has been trained to use it, the devices are maintained, and a paper copy is produced on request from a worker or the health and safety committee. Keeping accessible safety data sheets current is part of the same duty — the update rules are covered with the SDS sections.

What a WHMIS program must include — checklist

A practical WHMIS program should include the following elements:

• A hazardous product inventory — every classified product on site, with location and quantity. Nothing else in the program can be complete until this is.
• Labelling procedures — who creates workplace labels, from what template, using which printer, and who checks incoming supplier labels.
• SDS management — how sheets are obtained, where they live, who keeps them current, and how workers reach them on every shift.
• A worker education and training plan — who needs it, what generic education they receive, when, and how completion is recorded.
• Site-specific procedures — safe handling, storage, disposal, spill response and emergency procedures for the products in the inventory.
• A regular review process — a scheduled review of the program, in consultation with the joint health and safety committee or representative, with the date recorded.

Which products are exempt from WHMIS

WHMIS does not cover everything hazardous in a workplace. The following are excluded from some or all of the supplier requirements under the Hazardous Products Act: 2

• Explosives, as defined in the Explosives Act
• Cosmetics, devices, drugs and food, as defined in the Food and Drugs Act
• Pest control products, as defined in the Pest Control Products Act
• Consumer products, as defined in the Canada Consumer Product Safety Act
• Wood and products made of wood
• Nuclear substances that are radioactive, under the Nuclear Safety and Control Act
• Hazardous waste — a hazardous product sold for recycling or recovery, or intended for disposal
• Tobacco and tobacco products, as defined in the Tobacco and Vaping Products Act
• Manufactured articles

These are exclusions from the federal supplier rules on labels and safety data sheets — not from the duty to protect workers. Most of the products above are regulated under other legislation, provincial and territorial OHS duties continue to apply, and every one of them can still injure someone.

Where a consumer product is used at work, or a pest control product is applied on site, the employer must still identify the hazards and train workers on safe use, storage and disposal. Building the WHMIS program around only the WHMIS-regulated inventory is a common and expensive gap.

Program review and documentation

CCOHS's guidance is that the employer should review the WHMIS education and training program at least annually, in consultation with the joint health and safety committee or health and safety representative — and Ontario's OHSA makes an annual review a legal requirement (s. 42). 13 The review is not automatically retraining: its purpose is to establish whether the program still matches the workplace. Retraining is required whenever conditions change — new hazardous products, changed processes, new hazard information, or evidence that a worker cannot answer the four questions.

For documentation, the useful framing is not "what does the regulation say" but what an inspector actually asks for:

• Training records — who was trained, on what, when, and by whom, covering both generic education and site-specific training.
• The hazardous product inventory, current.
• Proof of SDS access — show the inspector where the sheets are and let a worker retrieve one.
• Review dates — the record of the program review and who was consulted.
• The workers themselves. Inspectors routinely speak to workers to confirm training happened. The four questions are the test.

Penalties for non-compliance

Two enforcement regimes can reach the same organization. Federally, under section 28 of the Hazardous Products Act, a person who contravenes the Act or its regulations is liable on summary conviction to a fine of up to $250,000 or six months' imprisonment for a first offence — rising to $500,000 and 18 months for a subsequent offence — and on conviction on indictment to a fine of up to $5,000,000 or two years' imprisonment, or both.

Health Canada inspectors can also order a supplier to stop selling or importing a product, seize product, and require corrective measures. These provisions bite on suppliers, importers and distributors — including employers who import for their own use. 2

Provincially, employer breaches are prosecuted under the applicable OHS statute, and the maximums are substantial. Three examples give the range:

• Ontario — under section 66 of the Occupational Health and Safety Act: up to $2,000,000 for a corporation, up to $1,500,000 for a director or officer, and up to $500,000 for any other person. For individuals, including directors and officers, up to 12 months' imprisonment can be added; a corporation can only be fined. Where a corporation is convicted of a second or subsequent offence that results in the death or serious injury of one or more workers within a two-year period, there is a minimum fine of $500,000. 3
• Alberta — under section 48 of the OHS Act: a first offence carries up to $500,000, plus a further $30,000 for each day a continuing offence continues, or six months' imprisonment; a second or subsequent offence carries up to $1,000,000, plus $60,000 per day, or 12 months. 4
• British Columbia — WorkSafeBC usually issues an administrative penalty rather than prosecuting. 5 The maximum is set by the Workers Compensation Act and re-indexed each 1 January in line with the consumer price index. 6

In practice, most WHMIS enforcement never reaches any of these numbers. It arrives as an inspector's order with a compliance deadline, and the real cost is the stop-work order and the remediation, not the fine. The figures matter because they set the ceiling — and because directors and officers are personally exposed in several jurisdictions.
