The Environmental Health and Safety (EHS) offices at St. George, UTM, and UTSC campus hosts respirator fit test sessions regularly throughout the year.
Fit testing is performed using a quantitative fit test method in accordance with the CSA Z94.4 standard. Participants who successfully pass their fit test will be provided with a wallet-sized certificate card indicating the respirator they were successfully fitted with (i.e., brand/model/size).
Fit test session duration: approx. 20-30 minutes.
If you have any questions regarding respirator fit testing, contact EHS at ehs.office@utoronto.ca.

About Respirator Fit Testing
Who is required to undergo respirator fit testing?
All University of Toronto staff and graduate students who are required to wear a tight-fitting respirator as part of their job duties or research work must be fit tested to ensure the user’s ability to obtain an effective seal and comfortable fit on the respirator. The training is designed to meet the University’s obligations under the University’s Respiratory Protection Program.
Important: Students who require a respirator fit test for a placement at an off-campus location (e.g., hospital) or undergraduate dental students who need a respirator fit test for clinical work must arrange for their fit test with a 3rd party vendor through their faculty or department. Speak to your faculty/department contact.
When should respirator fit testing be done?
Individuals must complete the online training and respirator fit testing prior to initial use of a tight-fitting respirator. Upon successfully completing a fit test, the individual must wear the specific make, model, and size of respirator they were fitted on for their work. Individuals who continue to require the use of a respirator must retake the online training and complete another fit test every two years or when the make/model of the respirator changes.

How to Sign Up for Respirator Fit Testing
- Log into My EHS Training with your UTORid and password and register for EHS532 Respiratory Protection Training (online).
- Once registered, individuals will receive instructions on how to access the course on Quercus.
- View the online training presentation in Quercus and complete the quiz with a minimum grade of 70%.
- Complete the Respiratory User Screening Form (Word version and PDF version).
Bring the completed form to the fit-test appointment. - Book your respirator fit-test appointment with your local EHS office using the links found on the homepage of the EHS 532 Respiratory Protection Training course (Quercus).
Preparing for your Respirator Fit Test
- Individuals must be clean-shaven where the respirator is in contact with the face in order to be fit tested.
- Avoid smoking, vaping, chewing gum, eating or drinking (except water) within 30 minutes of your fit test.
- Individuals should present themselves for fit testing in the same personal condition they expect to be in when using the respirator. This includes hair styles (e.g., ponytails) and wearing of dentures/braces/aligners (e.g., Invisalign), prescription glasses, or contact lenses.
- N95 Respirators: For participants who wish to be fitted for N95 respirators, please bring any NIOSH-approved models available to you to the fit test. If not available, the fit tester will fit you on an available Moldex model which can be purchased from the UofT MedStore afterwards. To confirm if an N95 respirator is NIOSH-approved, look for the TC approval code (e.g., “TC-84-XXXX”) on the respirator or packaging.
- Half- and Full-Face Elastomeric Respirators: Participants who have a 3M or Honeywell North brand elastomeric respirator (half-face or full-face) should bring their existing respirator to the fit test. If you do not already have one, the fit tester will fit you on an available Honeywell North model, which can be purchased from the UofT MedStore or uSOURCE afterwards.
Fit Test Centre Locations
UofT students/staff/faculty should book an appointment for fit-testing at the campus that they attend. UTM and UTSC students/staff/faculty who are attending research- or work-related training on St. George Campus may be eligible to attend a fit test session at the EHS office on St. George Campus. Contact your local EHS office for further information.

Other Options?
If there are logistical issues preventing you from attending a respirator fit test session on campus, you can arrange for your own fit test with a 3rd-party provider (Note: this service is not reimbursable by EHS). It is recommended that you choose a vendor that provides quantitative fit testing. After successful completion of the fit test, you must submit a copy of your fit test certificate to EHS. EHS will then update your training record on MyEHS Training.
Additional Information
Placements
Placement locations are responsible for providing training on hazards and procedures that are required at the placement site, including arranging for respirator fit testing. If the placement site is unable to provide respirator fit testing, please send details to EHS for review including relevant contact details of the placement site coordinator and UofT placement coordinator.
KN95 Respirators
Although Health Canada has authorized the use of some KN95 respirators for use related to COVID-19, KN95 respirators are not NIOSH-approved. EHS will not be able to fit test participants on any KN95 models.
Loose-fitting Facepiece Respirators
Respirator users who intend on only wearing loose-fitting facepiece respirators (e.g., PAPRs with hoods/headcovers) that do not require a fit test must still complete the online EHS532 Respiratory Protection Training course on Quercus and submit a completed Respiratory User Screening Form to EHS.
EHS can provide technical advice and recommendations on PAPR equipment but does not provide equipment-specific training. It is the responsibility of the respirator user to perform maintenance and inspections of the units purchased by their department following manufacturer’s instructions. Users should follow any manufacturer- or vendor-specified refresher frequency for equipment-specific training.
Accommodations
Certain respirator users may be unable to undergo a fit test on a tight-fitting facepiece respirator due to the need to maintain their facial hair for religious reasons (e.g., beard) or other medical reasons. These users may be eligible to wear loose-fitting facepiece respirators (e.g., hooded PAPRs) which do not require a respirator fit test.
EHS is not involved in approving requests for accommodations (religious or medical) or purchasing of PAPRs. For inquiries about an accommodation, refer to the following departments:
- Student Accommodations: The student should contact the Office of the Vice Provost, Students regarding their accommodation request for respirator use by e-mail: Office of the Vice-Provost, Students (ovps@utoronto.ca).
- Staff Accommodations: The employees’ department should contact Health and Well-Being Programs and Services (hwb@utoronto.ca).
