3.1 Codes & Regulations

Numerous federal, provincial, and industry standards govern access equipment in Canada. As an apprentice, you must understand which regulations apply to your work and how to access them. Regulations differ by province — always verify the current version for your jurisdiction.

3.1.1 — Key Canadian Standards and Acts

Canada Labour Code (Part II) — Canada OHS Regulations

Applies to federally regulated workplaces (federal government, banks, railways, telecommunications, interprovincial transport). Covers ladders, scaffolds, and aerial lifts for workers in these sectors.

Provincial Occupational Health & Safety Acts

The primary legislative authority for workplace safety in each province (e.g., Ontario OHSA, Alberta OHS Act). Defines employer and worker duties for all provincially regulated workplaces, which includes most HVAC-R job sites.

Ontario Reg. 213/91 — Construction Projects

Ontario Key Reg.

The Ontario regulation most directly applicable to HVAC-R work involving access equipment. Governs ladders, scaffolds, and aerial devices on construction sites and major renovations. Key sections include:

s.125(1) — Scaffold or equivalent required when work at height cannot safely be done from the ground or a permanent structure.
s.143 — Ladder requirements: condition, angle, securing, extension above landing.
s.144–148 — Scaffold construction, guardrails, and load requirements.
s.149–161 — Elevating work platforms: operator training, inspection, and safe use.

CSA Z797 — Code of Practice for Access Scaffold

Governs the design, erection, use, inspection, and dismantling of supported access scaffolding. Widely referenced by provincial regulations and employers as the standard of practice for scaffold work in Canada.

CSA Z271 — Safety Code for Suspended Elevating Platforms

Covers suspended scaffolds such as swing stages and mast climbers. Applies when working from platforms hung from the building structure rather than supported from the ground.

CSA B354 Series — Elevating Work Platforms

Covers the design, testing, maintenance, and operation of aerial work platforms including scissor lifts and boom lifts. Operators must be trained and equipment must be inspected per this standard before each use.

CSA Z259 Series — Fall Protection

Addresses personal fall arrest systems, lanyards, anchors, and harnesses used at heights. When working at any elevation requiring fall protection, the equipment used must meet the applicable Z259 standard.

Z259.10 — Full-body harnesses
Z259.11 — Energy absorbers and lanyards
Z259.16 — Design of active fall-protection systems

ANSI/ASSE A10.8 — Scaffolding Safety Requirements

An American standard widely referenced in Canadian practice for scaffold design and use. Often cited in manufacturer documentation and adopted as a baseline by employers where provincial standards do not specify otherwise.

OSHA 1926 Subpart L (US) — Referenced in Canadian Contexts

US scaffolding safety regulation often referenced in manufacturer documentation and imported equipment. Familiarity with this standard helps when working with American equipment or interpreting supplier manuals.

Manufacturer’s Specifications

Always Required

Always read and follow the manufacturer’s manual. It forms part of the regulatory framework for that specific piece of equipment and may be more restrictive than the minimum code requirements. Exceeding rated loads or using equipment outside its intended purpose is a regulatory violation even if the code itself does not specify that exact scenario.

💡

Pro Tip

When in doubt about which regulation applies, start with your provincial OHS Act, then check Ontario Reg. 213/91 (or the equivalent in your province) for construction-specific requirements, then refer to the applicable CSA standard for technical details. Always confirm with your supervisor or the Authority Having Jurisdiction (AHJ).

3.1.2 — Employer and Worker Obligations

Under occupational health and safety legislation, both employers and workers carry defined legal responsibilities for the safe use of access equipment. These are not optional guidelines — they are enforceable legal duties.

Employer Responsibilities OHS Legislation

Ensure that only approved access equipment is provided on the job site.
Ensure workers are trained in the safe use, inspection, and maintenance of access equipment before use.
Ensure competent persons supervise the erection and dismantling of scaffolding systems.
Maintain records of equipment inspections and certifications.
Provide appropriate PPE, including fall protection equipment.

Worker Responsibilities OHS Legislation

Inspect all access equipment before each use and report defects immediately.
Use access equipment only for its intended purpose and within rated loads.
Complete required working-at-heights training before working on any elevated surface.
Follow all safe work practices and site-specific procedures.
Wear and properly use fall protection equipment as required.

3.1.3 — Working at Heights Training

Ontario: Working at Heights (WAH) Training Certificate

Mandatory

In Ontario, workers on construction projects who may work at heights (≥ 3 m from a fall hazard) must hold a valid Working at Heights (WAH) training certificate from a Ministry of Labour, Training and Skills Development (MLTSD)-approved provider.

Must be completed before working at heights on a construction project.
Must be renewed every three years.
Training must be from an MLTSD-approved provider — employer-developed courses do not qualify unless approved.
Similar mandatory WAH training requirements exist in all Canadian provinces under their respective OHS regulations.

⚠

Provincial Variation Note

Regulations vary significantly across provinces. For example, the minimum height that triggers mandatory fall protection is 3 m in Ontario (construction), but may differ in Alberta, British Columbia, or Quebec. Always check the specific regulation for the province where you are working. Never assume that what applies in Ontario automatically applies elsewhere.
