In Quebec, eye injuries rank among the most frequent workplace accidents recorded by the CNESST each year. The majority could have been prevented with protective equipment properly matched to the position.
For an occupational health and safety (OHS) manager or a human resources (HR) director, the real question is straightforward: at what point does the law require safety glasses to be provided? The answer is more precise than it appears — and it directly engages the employer’s liability.
This article clarifies your obligations, the positions affected, and the steps to build a compliant program.
What Quebec Law Says About Eye Protection
Section 51 of the Act Respecting Occupational Health and Safety (AOSAS) requires employers to take “all necessary measures to protect the health and ensure the safety” of their workers. As soon as an eye hazard is identified, the obligation to provide compliant personal protective equipment (PPE) applies.
Three points to keep in mind:
- Mandatory coverage. Purchase, normal replacement, and maintenance are the employer’s responsibility. No cost may be transferred to the employee — including for prescription eyewear.
- Applicable standard. In Canada, the reference is CSA Standard Z94.3. The certification must be visible on the protector. The American standard ANSI Z87.1 is not recognized by the CNESST, unless the product also carries the CSA marking
Universal obligation. It applies regardless of organization size — 10 or 500 employees.
Who Is Affected?
Eye protection is not reserved for construction sites. It is the hazard assessment — not the job title — that triggers the obligation.
The Regulation Respecting Occupational Health and Safety (RROHS) identifies four hazard categories:
- Mechanical: flying particles, chips, fragments
- Chemical: corrosive splashes, vapours, aerosols
- Physical: radiation (welding, laser, UV), heat, blinding light
- Biological: infectious agents through the ocular route
As soon as one of these hazards is present, CSA Z94.3-certified glasses must be provided.
Among the highest-risk sectors: construction, manufacturing, industrial mechanics, laboratories, forestry, and wood processing. That said, warehouse or office laboratory positions may also involve risks. This is why a position-by-position assessment is essential.
How to Assess Ocular Risk for Your Workers
The AOSAS requires employers to identify hazards before determining prevention measures. The process follows three steps:
- Identify at-risk tasks — both regular and occasional.
- Assess the likelihood and severity of exposure.
- Document the conclusions in writing — this is the document the CNESST will request during an inspection.
Risks of Non-Compliance
The CNESST may intervene without notice, whether or not an accident has occurred. Possible sanctions include:
- Correction notice with a compliance deadline
- Formal notice if the order is not respected
- Fines potentially reaching several thousands of dollars
- Work stoppage order in cases of immediate danger
Add to this the indirect costs of a workplace accident: increased CNESST assessment rates, worker compensation, impact on productivity and reputation.
Up-to-date documentation — hazard assessments, PPE provided, CSA compliance evidence — is the first line of defence during an audit.
Building an Eye Protection Program That Holds Up
The law requires you to act. The quality of the program determines its adoption and real-world compliance. Three criteria matter:
1. The quality of the safety glasses
Uncomfortable PPE will be abandoned. Frames must be durable, well-fitted, and CSA Z94.3-certified — including prescription models.
2. An extensive care provider network
Employees must be able to consult a partner optometrist close to their worksite. The network directly conditions adoption, especially for multi-site organizations.
3. Sector-specific expertise
Every industry has its own requirements — welding, chemicals, forestry. Frame selection must reflect on-the-ground realities.
How LookSecure Supports Employers
LookSecure partners with large Canadian organizations to implement compliant eye protection programs, from the initial assessment through to billing. The platform centralizes data by site and employee, automates approvals, and generates the documentation required for CNESST audits.
For multi-site organizations, this approach standardizes compliance across all facilities and gives OHS managers real-time visibility into program status.
Three Actions to Take This Week
1. Launch a position-by-position hazard assessment
Use the RROHS and CSA Z94.3 standard to analyze the risks specific to each role. A well-documented assessment is the foundation of a serious, consistent, and audit-ready eye protection program.
2. Determine the frames best suited to field realities
Every position comes with its own constraints. Dusty environments, outdoor work, extended wear, compatibility with other protective equipment: the frames selected must respond to actual working conditions to support comfort, adoption, and compliance.
3. Build a complete, sustainable program
Beyond frame selection, it is essential to establish a clear framework: access to a care provider network, replacement rules, centralized documentation, and streamlined management processes. This is what enables an effective, consistent, and easy-to-administer program.

FAQ
The employer. The AOSAS mandates full coverage: purchase, replacement, and maintenance.
Yes, when a position involves an eye hazard and the employee requires vision correction. Over-glasses worn on top of personal eyewear can serve as a temporary solution, but are not a sustainable option.
No. Only CSA Z94.3 certification is recognized by the CNESST. A product carrying both CSA and ANSI certification is compliant.
