Health Canada chemical labels for cleaning products: WHMIS and CCCR basics

What to take away

This is general information from federal guidance, not legal advice.

Two systems, two audiences

A cleaning business sits on the boundary of both systems. It buys products, often from a distributor, and it uses them at a customer's home or at its own premises with employees.

WHMIS is the Workplace Hazardous Materials Information System. Health Canada administers the Hazardous Products Act, which sets labelling and SDS requirements for suppliers. The Hazardous Products Regulations set out the hazard classification and communication requirements. Health Canada describes the system as aligned with the Globally Harmonized System, an internationally consistent approach to classifying chemicals and communicating hazards through labels and SDSs.

CCCR means the Consumer Chemicals and Containers Regulations, 2001. Health Canada's page on the regulations publishes four hazard symbols, for toxic, corrosive, flammable and explosive. Its household chemical safety page explains how consumers read them. The symbol has a frame shape: a triangle means the container is dangerous, and an octagon means the contents are dangerous. The signal word shows the degree of risk, with CAUTION for temporary injury, DANGER for temporary or permanent injury or death, and EXTREME DANGER for very small amounts that may cause death or serious injury.

The two systems use different label elements. A WHMIS supplier label includes a product identifier, an initial supplier identifier, pictograms, the signal word Danger or Warning, hazard statements, precautionary statements and any required supplemental information, according to the Canadian Centre for Occupational Health and Safety (CCOHS).

Which label do you actually have in your van

The answer depends on how the product was supplied. Health Canada's supplier page says WHMIS supplier requirements apply to suppliers of hazardous products destined for Canadian workplaces. It also lists categories that are excluded, including consumer products as defined in section 2 of the Canada Consumer Product Safety Act, cosmetics, drugs, food, pest control products and others. The page does not mention the CCCR.

For a cleaner, that gives a practical rule for reading a bottle:

The Health Canada pages reviewed do not say what employer duties apply when a consumer-labelled product is used as a work product. Ask your provincial occupational health and safety authority before you assume either way.

What employers must do under WHMIS

Health Canada's roles and responsibilities page assigns these duties to employers:

Workers take part in WHMIS and chemical safety training, take the necessary steps to protect themselves and co-workers, and help identify and control hazards.

CCOHS separates education from training. Education is general, portable information about how WHMIS works and the hazards of products. Training is workplace-specific and covers local procedures for storage, handling, use, disposal and emergencies. Employers must develop, implement and maintain a program, give product-specific training, and share the hazard information they have. CCOHS says employers should review the program at least annually, or sooner when conditions, products or hazard information change. Some provinces or territories may require periodic checks of worker knowledge.

Health Canada states that each of the 13 provincial, territorial and federal occupational health and safety agencies has established WHMIS requirements for employers within its jurisdiction. A cleaner in Ontario and one in Alberta may therefore find different wording and enforcement, even though the label system is the same. The site's guide to workers compensation for cleaning crews in Ontario and Alberta covers the insurance side of the same split, and the hiring and training guide covers building training into onboarding.

Decanting and workplace labels

Cleaners often pour concentrate into spray bottles, bonnets or a portable extractor tank. This is called decanting. CCOHS says a workplace label is required when:

A workplace label must show the product name, which matches the SDS, safe handling precautions that may include pictograms or other supplier label information, and a reference to the SDS if one is available.

There are exceptions. A label is not required when the product is poured and used immediately. A product is also treated as under the control of the person who decanted it when that person is the only one using it, during one shift, though the container still needs the product name. A full workplace label is needed if the product will not be used right away or more than one person will control it. CCOHS adds that workplace label rules fall under provincial or territorial jurisdiction, so confirm them locally.

For a crew, the safe routine is simple. Label every refillable bottle before it leaves the shop, using the product name from the SDS and the handling precautions, and keep the SDS where the crew can reach it. The SOP checklist for daily operations is the natural place to add this step.

Storage, SDS access and records

Health Canada states that suppliers must provide labels and SDSs to purchasers of hazardous products intended for use in a workplace, and that a product must be relabelled if its supplier label is lost, damaged or unreadable. SDSs must be available in English and French, either as one bilingual document or two unilingual ones.

Practical records for a cleaning business:

CCOHS does not address record-keeping requirements on its training page and refers readers to local occupational health and safety rules, so check how long your jurisdiction expects you to keep training records. The broader compliance file is described in the licensing and compliance guide.

Common questions

Is WHMIS the same as the consumer hazard symbols?

No. WHMIS applies to hazardous products supplied to workplaces under the Hazardous Products Act. The consumer symbols come from the Consumer Chemicals and Containers Regulations and apply to products sold to the public.

Do I need a label for a spray bottle I filled this morning?

CCOHS says a workplace label is needed when a product is decanted, unless it is used immediately or stays under the control of the person who decanted it during one shift. The bottle still needs the product name.

Who enforces WHMIS rules for my employees?

Health Canada says each provincial, territorial and federal occupational health and safety agency has established WHMIS requirements for employers in its jurisdiction.

Do the SDSs need to be in French?

Health Canada states that SDSs must be available in both English and French, as one bilingual document or two unilingual ones.
