Respiratory Protection Compliance for Ontario Employers
Comprehensive Programs That Meet Regulation 833 and CSA Z94.4 Standards
When respirators are required in your workplace, compliance is not optional. Ontario Regulation 833 and CSA Z94.4 require employers to develop a written respiratory protection program, ensure workers are trained, and verify respirator fit through certified testing.
WorkBright’s Respiratory Protection Compliance Package is built to simplify that process. We help you protect your workers from airborne hazards—and demonstrate due diligence to regulators.
What’s Included in the Compliance Package
Jump to a section:
Step 1: Develop a Respiratory Protection Program
Step 2: Respiratory Protection Training (eLearning)
Respiratory Protection Program Requirements for Workplaces
In Ontario, Regulation 833: Control of Exposure to Biological or Chemical Agents requires employers to establish written measures and procedures regarding the selection, care and use of respirators.
Our Five-Step Process.
Step 1: Develop a Written Respiratory Protection Program
We collaborate with your team to create or update a compliant written program, including:
- Responsibilities
- Hazard identification and assessment
- Respirator selection
- Fit testing
- Use of respirators
- Maintenance, cleaning, and storage guidelines
- Recordkeeping
- Program evaluation
This foundational document is essential for compliance and demonstrates your commitment to employee health.
Step 2: Respiratory Protection eLearning
Each users completes a 15-minute eLearning module ahead of the date that covers:
- Responsibilities and the law
- Fit testing
- Proper respirator usage and limitations
- Maintenance and care procedures.
The training is available in multiple languages and includes completion tracking to ensure readiness for fit testing.
Step 3: Consultation with an Occupational Hygienist
Our occupational hygienist will:
- Review your work processes
- Assess workplace hazards
- Recommend appropriate respirator types (e.g., N95, half-mask, full-face)
- Advise on suitable filters and cartridges
This expert guidance ensures your respiratory protection program aligns regulatory requirements in O.Reg.833.
Step 4: Respirator Supply
We provide NIOSH-approved respirators appropriate for the hazards workers may encounter.
- NIOSH-approved N95s, half-mask, or full-face models
- Filters and cartridges
- Various sizes to ensure proper fit
We also offer ongoing supply support to help manage inventory for future needs.
Step 5: Qualitative and Quantitative Fit Testing
Fit testing is a legal requirement in O.Reg.833 and ensures each employee’s respirator provides the intended protection. Our certified professionals conduct on-site qualitative and quantitative fit testing, adhering to CSA Z94.4 standards.
- Preliminary assessment to ensure your workforce is prepared for fit testing
- Respirator overview and training
- Fit test
- Record of fit test provided to each user

What happens during a fit test?
Fit testing involves wearing a tight-fitting respirator while undergoing a series of exercises that simulate workplace movements. We use either a qualitative method (relying on taste or smell) or a quantitative method (using a machine to measure leakage). The test determines whether the respirator forms a proper seal to the user’s face.
Do you offer both qualitative and quantitative fit testing?
Yes. We provide both methods in accordance with CSA Z94.4 standards. Our team will recommend the best option based on the respirator type and work environment.
How long does the fit test take from start to finish?
The process takes approximately 20 to 25 minutes, depending on the number of participants in each group.
Do all workers need to be clean shaven to wear a respirator?
In most cases, yes. CSA Z94.4 requires that no facial hair interfere with the sealing surface of a tight-fitting respirator. Workers must be clean shaven where the mask contacts the face to ensure proper protection and fit test validity. We provide guidance on facial hair compliance during program implementation.
Can we use our existing respirators?
Yes, if they meet NIOSH standards and are suitable for the work tasks. During the consultation, we’ll verify compatibility and make any necessary recommendations.
Are you certified to perform fit testing?
Yes. Our fit testing is performed by certified professionals under the direction of ROHs and CIHs, with full documentation and compliance assurance.
How should I prepare for a fit test?
Workers should be clean-shaven where the mask seals to the face. They should avoid eating, smoking, or drinking (except water) at least 15 minutes prior to testing. Long hair should be tied back so it does not interfere with the respirator seal.
Can workers be tested in groups?
Yes. We can fit test up to five workers per session, depending on the method used and site logistics. Group testing helps keep your operations efficient while maintaining compliance.
What if an employee fails the fit test?
If a worker does not pass with the first respirator, we may attempt a second fit with an alternative model or size. Only respirators that pass the test should be used. All results are documented for your records.
How often is fit testing required?
CSA Z94.4 recommends fit testing at least every two years, or sooner if there is a change in the worker’s physical condition, the respirator model, or after any failure in the respirator program.
Is a written respiratory protection program mandatory in Ontario?
Yes. Under Regulation 833 and CSA Z94.4, any employer requiring respirator use must have a documented program outlining procedures, responsibilities, training, and fit testing.
