In commercial cleaning, safety is just as important as cleanliness. Every day, cleaning teams handle products that can pose risks if not used, stored, or disposed of properly. In Canada, the Workplace Hazardous Materials Information System (WHMIS) provides the framework to ensure that workers understand these risks and know how to protect themselves.

As we move into 2026, WHMIS compliance remains a critical responsibility for businesses across Toronto and the GTA. For commercial cleaning teams, this means more than just knowing how to clean—it means understanding hazardous materials, following safety protocols, and maintaining a safe work environment.

This guide explains what WHMIS compliance involves and what your cleaning crew needs to know to stay safe and compliant.

What Is WHMIS and Why It Matters

WHMIS is Canada’s national system for communicating information about hazardous workplace products. It ensures that workers are informed about the potential dangers of chemicals and other materials they use on the job.

For cleaning crews, this is especially relevant because many commonly used products—such as disinfectants, degreasers, and floor cleaners—can contain hazardous substances.

WHMIS helps answer key questions:

• What hazards does this product present?
• How can it be used safely?
• What should be done in case of exposure or an emergency?

By providing clear information through labels, safety data sheets, and training, WHMIS helps reduce workplace injuries and health risks.

Understanding Hazardous Materials in Cleaning

Not all cleaning products are harmless. Some may cause skin irritation, respiratory issues, or more serious health effects if handled incorrectly.

Common hazardous materials in commercial cleaning include:

• Strong disinfectants and sanitizers
• Chemical degreasers
• Floor stripping and waxing solutions
• Glass and surface cleaners with high chemical content

Even products that seem routine can become hazardous when mixed improperly or used without proper ventilation.

This is why it is essential for cleaning staff to understand the materials they work with every day.

WHMIS Labels: What to Look For

One of the core elements of WHMIS is proper labeling. Every hazardous product used in the workplace must have a label that clearly identifies its risks.

These labels typically include:

• Product name
• Hazard symbols (pictograms)
• Signal words such as “Danger” or “Warning”
• Precautionary statements

Cleaning staff must be trained to recognize these labels and understand what they mean. A quick glance at a label should provide enough information to handle the product safely.

Safety Data Sheets (SDS): Your Go-To Resource

Safety Data Sheets, often referred to as SDS, are detailed documents that provide comprehensive information about a product.

They include:

• Chemical composition
• Potential hazards
• Safe handling procedures
• First aid measures
• Storage and disposal guidelines

Every cleaning crew should know where SDS documents are located and how to access them quickly. In case of an incident, these sheets provide critical information that can prevent serious harm.

Proper Handling and Storage Practices

Handling hazardous materials safely is a key part of WHMIS compliance.

Cleaning teams should follow best practices such as:

• Using products only as directed
• Avoiding mixing chemicals unless explicitly instructed
• Wearing appropriate personal protective equipment (PPE)
• Ensuring proper ventilation during use

Storage is equally important. Chemicals should be kept in clearly labeled containers and stored in designated areas away from incompatible substances.

Improper storage can lead to leaks, spills, or dangerous chemical reactions.

The Importance of Personal Protective Equipment (PPE)

Personal protective equipment is a frontline defense against exposure to hazardous materials.

Depending on the task, this may include:

• Gloves
• Safety goggles
• Masks or respirators
• Protective clothing

Cleaning staff must understand when PPE is required and how to use it correctly. Simply having protective equipment available is not enough—it must be used consistently and properly.

Training and Education Requirements

WHMIS compliance requires that all workers who handle hazardous materials receive proper training.

This training should cover:

• Understanding labels and pictograms
• Reading and using SDS
• Safe handling and storage procedures
• Emergency response actions

Training is not a one-time activity. It should be updated regularly to reflect new products, updated regulations, and changes in workplace procedures.

For cleaning companies, ongoing education ensures that teams remain confident and capable in handling hazardous materials safely.

Emergency Preparedness and Response

Even with proper precautions, accidents can happen. WHMIS emphasizes the importance of being prepared for emergencies.

Cleaning crews should know how to respond to:

• Chemical spills
• Skin or eye exposure
• Inhalation of fumes
• Accidental ingestion

Clear procedures should be in place, including access to first aid supplies and emergency contact information.

Quick and informed action can significantly reduce the impact of an incident.

Compliance Responsibilities for Employers

Employers play a critical role in ensuring WHMIS compliance.

They are responsible for:

• Providing proper training
• Ensuring all hazardous products are labeled
• Making SDS readily available
• Supplying appropriate PPE
• Maintaining safe work procedures

For businesses in Toronto, compliance is not just about following regulations—it’s about protecting employees and maintaining a safe workplace.
