Alberta hearing conservation requirements are set by Alberta Occupational Health and Safety (within Jobs, Economy and Trade) under Occupational Health and Safety Act (SA 2020, c. O-2.2) and implemented through Occupational Health and Safety Code, Part 16 (Noise) — sections 218–227. There is no single “Canadian OSHA” — provincially regulated workplaces in Alberta (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 Alberta 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 Alberta 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 Alberta operations.
Alberta OH&S Overview
Occupational health and safety in Alberta is administered by Alberta Occupational Health and Safety (within Jobs, Economy and Trade) under Occupational Health and Safety Act (SA 2020, c. O-2.2). Noise and hearing conservation requirements are set out in Occupational Health and Safety Code, Part 16 (Noise) — sections 218–227. Unlike the US state-plan system — where state programs adopt federal OSHA standards by reference — Alberta’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 Alberta.
Federally regulated workplaces in Alberta — interprovincial trucking, rail, air, marine, banking, telecommunications, federal Crown corporations — follow the federal COHSR Part VII noise rule, not the provincial regulation. Everyone else — manufacturing, construction, healthcare, retail, agriculture, provincial Crown corporations — follows the provincial rule covered in this guide.
Hearing Conservation Requirements in Alberta
| Requirement | Alberta |
|---|---|
| Regulator | Alberta Occupational Health and Safety (within Jobs, Economy and Trade) |
| Governing statute | Occupational Health and Safety Act (SA 2020, c. O-2.2) |
| Noise regulation | Occupational Health and Safety Code, Part 16 (Noise) — sections 218–227 |
| Action level | 85 dBA Lex,8 |
| Exposure limit | 85 dBA Lex,8 |
| Exchange rate | 3 dB (equal-energy) |
| Audiometric testing | Mandatory — baseline within 6 months, every 2 years thereafter (s. 221) |
| HPD standard | CSA Z94.2 (current edition) — referenced via s. 224 |
| Noise measurement standard | CSA Z107.56 (current edition) |
Audiometric testing. Audiometric testing is mandated by OHS Code s. 221: a baseline audiogram is required within 6 months of a worker first being exposed at or above 85 dBA Lex,8, with follow-up audiograms required at least every 2 years (more frequent than the federal-state norm, but on a 2-year rather than annual cycle). Audiograms must be conducted by an audiometric technician approved by an Alberta-registered audiologist.
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 s. 224. 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.
Alberta is the largest Canadian oil and gas employer base — upstream drilling rigs, oil sands operations, and gas plants are all subject to OHS Code Part 16. The 2-year (rather than annual) audiometric cycle is distinctive in Canada but reflects Alberta's historical alignment with the equal-energy / industrial-hygiene approach.
Jurisdiction and Coverage
The provincial noise regulation covers private-sector employers and provincial/municipal government employers operating in Alberta. Federally regulated employers in Alberta 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.
| Employer Type | Governing Regulator | Noise Rule |
|---|---|---|
| Private sector in Alberta | Alberta Occupational Health and Safety | Occupational Health and Safety Code |
| Provincial/municipal government | Alberta Occupational Health and Safety | Occupational Health and Safety Code |
| Federally regulated (interprovincial transport, banking, telecom, federal Crown) | Employment and Social Development Canada / Labour Program | COHSR Part VII (SOR/86-304) |
| Cross-border US operations | US OSHA or state-plan OSHA | 29 CFR 1910.95 |
Enforcement and Penalties
Under the OHS Act, individuals convicted of an offence face fines up to CAD $500,000 and/or up to 6 months imprisonment; corporations face fines up to CAD $1,500,000 for a first offence and up to CAD $3,000,000 for a subsequent offence. Administrative penalties up to CAD $10,000 per day per contravention can be issued by OHS officers without prosecution.
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 Alberta
The following sectors in Alberta consistently generate occupational noise exposures that trigger the hearing conservation program: oil and gas (upstream drilling, oil sands, midstream processing), petrochemical (Industrial Heartland), construction, agriculture (covered with limitations), and trucking. 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 Alberta
A hearing conservation program that satisfies Occupational Health and Safety Code in Alberta 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 s. 224, with selection documented against measured exposure.
- Audiometric testing per the regulator’s expectations — mandatory — baseline within 6 months, every 2 years thereafter (s. 221).
- 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 Alberta will generally also satisfy US OSHA 29 CFR 1910.95, since Z1007’s audiometric and training elements are stricter than the US OSHA floor.

The action level in Alberta is 85 dBA Lex,8, with an exposure limit of 85 dBA Lex,8 and a 3 dB (equal-energy) exchange rate. Once a worker is exposed at or above the action level, the employer must implement a hearing conservation program covering noise assessment, engineering and administrative controls, hearing protection devices, worker education, and audiometric testing as required by the regulation.
Audiometric testing is mandated by OHS Code s. 221: a baseline audiogram is required within 6 months of a worker first being exposed at or above 85 dBA Lex,8, with follow-up audiograms required at least every 2 years (more frequent than the federal-state norm, but on a 2-year rather than annual cycle). Audiograms must be conducted by an audiometric technician approved by an Alberta-registered audiologist.
Under the OHS Act, individuals convicted of an offence face fines up to CAD $500,000 and/or up to 6 months imprisonment; corporations face fines up to CAD $1,500,000 for a first offence and up to CAD $3,000,000 for a subsequent offence. Administrative penalties up to CAD $10,000 per day per contravention can be issued by OHS officers without prosecution.
Alberta regulators cite CSA Z94.2 (Hearing Protection Devices) for HPD selection and CSA Z107.56 (Measurement of Noise Exposure) for noise surveys and dosimetry. CSA Z1007 (Hearing Loss Prevention Program Management) is the recognized program-management standard and is treated as the standard of care for HCP design across Canadian jurisdictions.
