Quebec Hearing Conservation Requirements: Commission des normes, de l'équité, de la santé et de la sécurité du travail Employer Guide

Quebec hearing conservation requirements are set by Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) under Act respecting occupational health and safety (RLRQ c. S-2.1) and implemented through Regulation respecting occupational health and safety — RSST (RLRQ c. S-2.1, r. 13), sections 130–141 (as amended 2023, in full force 2024). There is no single “Canadian OSHA” — provincially regulated workplaces in Quebec (the great majority of employers in the province) follow this provincial regulation rather than the federal Canada Occupational Health and Safety Regulations (COHSR). This guide is the Quebec expansion of our Canada vs. Federal OSHA hearing conservation pillar, covering the action level, exposure limit, audiometric testing requirements, HPD and measurement standards, key noise-exposed industries, and penalty structure for Quebec employers.

Soundtrace delivers audiometric testing and noise monitoring tooling for employers operating in Canada and the United States — ANSI S3.1 / CSA Z107.56-aligned and supervised by a licensed audiologist. Contact us about Quebec operations.

Quebec OH&S Overview

Occupational health and safety in Quebec is administered by Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) under Act respecting occupational health and safety (RLRQ c. S-2.1). Noise and hearing conservation requirements are set out in Regulation respecting occupational health and safety — RSST (RLRQ c. S-2.1, r. 13), sections 130–141 (as amended 2023, in full force 2024). Unlike the US state-plan system — where state programs adopt federal OSHA standards by reference — Quebec’s noise regulation is a standalone provincial instrument that the regulator drafted and enforces directly. There is no federal Canadian floor that applies to provincially regulated workplaces in Quebec.

Hearing Conservation Requirements in Quebec

Audiometric testing. Audiometric surveillance is delivered under the Public Health Network through the CNESST hearing health surveillance program (Programme de santé spécifique à l'établissement, PSSE). Employers in noise-exposed sectors are required to participate in audiometric surveillance under the PSSE, which is coordinated through regional public health authorities.

Hearing protection. Where exposures cannot be reduced below the exposure limit through engineering or administrative controls, the employer must provide hearing protection devices selected and used in accordance with CSA Z94.2 (current edition) — referenced via CNESST guidance. CSA Z94.2 uses an A-B-C classification (Class A is the highest-attenuation, Class C is the lowest) and provides selection guidance based on measured exposure — this is the Canadian counterpart to the US NRR derating framework. See: audiometric testing for employers.

Noise measurement. Noise surveys and dosimetry must be conducted in accordance with CSA Z107.56 (current edition), which specifies measurement strategy, instrument calibration, and reporting requirements for occupational noise exposure assessments.

Jurisdiction and Coverage

The provincial noise regulation covers private-sector employers and provincial/municipal government employers operating in Quebec. Federally regulated employers in Quebec are covered by COHSR Part VII (the federal rule). Mining is generally covered by the provincial OH&S regime with sector-specific noise provisions in some jurisdictions; offshore oil and gas is regulated by joint federal-provincial offshore safety boards where applicable.

Enforcement and Penalties

Under the LSST (s. 236–237), penalties for a first offence by a corporation range from CAD $1,728 to $69,131; for a subsequent offence from $3,456 to $172,827. Individual penalties scale separately. Fine amounts are indexed annually. A wilful or reckless violation that endangers a worker can attract substantially higher fines under s. 237.

For comparison with US enforcement, see our OSHA hearing conservation violations and penalties guide. Canadian penalty maximums are denominated in Canadian dollars and are typically higher per-offence than US OSHA maximums — though Canadian regulators generally pursue prosecution less frequently than US OSHA pursues citations, relying more heavily on administrative orders, stop-work orders, and experience-rated WCB premium adjustments.

Key Noise-Exposed Industries in Quebec

The following sectors in Quebec consistently generate occupational noise exposures that trigger the hearing conservation program: aluminum smelting (Saguenay), pulp and paper, aerospace (Montreal), mining (Abitibi-Témiscamingue), forestry and sawmills, food and beverage processing, and construction. Employers in these sectors should prioritize noise assessment by job classification under CSA Z107.56 (current edition) to identify which workers exceed the action level.

Building a Compliant HCP in Quebec

A hearing conservation program that satisfies Regulation respecting occupational health and safety — RSST (RLRQ c. S-2.1 in Quebec should follow CSA Z1007 (Hearing Loss Prevention Program Management) as the program-design framework. The core elements:

• Noise assessment under CSA Z107.56 (current edition) — identify which workers exceed 85 dBA Lex,8.
• Engineering and administrative controls first, where reasonably practicable — HPDs are a control of last resort, not the primary control.
• Hearing protection devices selected and used per CSA Z94.2 (current edition) — referenced via CNESST guidance, with selection documented against measured exposure.
• Audiometric testing per the regulator’s expectations — mandatory (cnesst hearing surveillance under psse).
• Worker education on noise hazards, control measures, HPD selection and use, and the audiometric program.
• Recordkeeping covering noise assessments, HPD program documentation, and audiometric records retained for the working life of the worker (per CSA Z1007).
• Program review at least annually and whenever workplace conditions change materially.

For cross-border employers, a CSA Z1007-aligned program built for Quebec will generally also satisfy US OSHA 29 CFR 1910.95, since Z1007’s audiometric and training elements are stricter than the US OSHA floor.
