Law, standards and qualifications

Lifting is one of the most heavily regulated activities on a work site. The rules come in layers: a general health and safety statute, regulations that set specific requirements for cranes, hoists and rigging, technical standards that regulations adopt by reference, the manufacturer's instructions, and finally the employer's own program. A supervisor does not need to memorize every clause, but does need to know which layer answers which question and where to look.

This lesson maps those layers, explains who must hold which qualification, and shows how to check that the people doing a lift are allowed to do it. Requirements change and vary by jurisdiction, so always confirm the current version of the rules that apply where you work. The citations here were checked in October 2026.

The statute: general duties

Each province and territory has an occupational health and safety act, and federally regulated workplaces fall under Part II of the Canada Labour Code. In Ontario, the Occupational Health and Safety Act requires employers to provide information, instruction and supervision, to make sure equipment is maintained in good condition, and to take every precaution reasonable in the circumstances. Supervisors must make sure workers follow the regulations and use the protective devices required, and must advise workers of known hazards. Workers must use equipment as required and report defects. These general duties apply to every lift whether or not a specific regulation covers it.

Regulations for cranes, hoists and rigging

Regulations turn the general duties into specific requirements. In Ontario, Regulation 213/91 (Construction Projects) and Regulation 851 (Industrial Establishments) are the two most relevant.

Other provinces follow similar patterns with their own numbering. Alberta's OHS Code Part 6 (sections 59 to 114) covers cranes, hoists and lifting devices, including load charts, operator requirements, log books, a written lift calculation whenever a load reaches 75 per cent or more of the crane's capacity (section 68.1), loads over work areas, tag lines and hand signals. Rigging is in Part 21 (sections 292 to 309). British Columbia's Occupational Health and Safety Regulation places cranes and hoists in Part 14 and rigging in Part 15. Federally regulated workplaces, such as ports and some transport operations, follow the Canada Occupational Health and Safety Regulations.

Standards adopted by reference

Regulations often say that a crane must be designed, inspected or operated in accordance with a named standard. When they do, that edition of the standard becomes part of the legal requirement. When they do not, standards still describe good practice, and inspectors and courts use them to judge whether an employer took reasonable precautions.

A regulation may name an older edition than the one currently on sale. Alberta's code, for example, was written around earlier editions of CSA Z150 and Z248. Where the regulation names an edition, that edition sets the legal minimum, but following the newer edition is usually good practice and is often what manufacturers and owners expect.

The manufacturer's instructions

Every crane has an operator's manual and a load chart specific to its model, serial number and configuration. Regulations in both countries require cranes to be used within the manufacturer's ratings and instructions. If the manual says the crane must be level within 1 per cent, or that a particular jib may not be used in winds above a given speed, that limit is binding. Modifications that affect capacity or safe operation generally need the manufacturer's approval or an engineer's design.

Qualifications: who may do what

Lifting involves several distinct roles, and each has its own qualification. A common audit finding is a site that checks the crane operator's card carefully but never asks who is rigging or signalling.

In Ontario, the crane's rated capacity, not the weight of the load being lifted, decides which certificate the operator needs. The Ministry of Labour has said that derating a crane simply to avoid hiring a certified operator is not acceptable; a crane may only be derated by physical changes that cannot easily be reversed. The ministry also notes that excavators, backhoes and forklifts used to hoist material are not cranes for the purpose of the certificate requirement, but the rigging rules and the duty to train still apply.

Duties of employers, supervisors and workers

Whatever the jurisdiction, the duties fall into a familiar pattern.

• The employer selects suitable equipment, makes sure it is inspected and maintained, provides qualified people, develops a lifting program and plans for critical lifts, and makes sure everyone is trained.
• The supervisor or lift director checks qualifications and documents, confirms the lift plan matches site conditions, controls the area around the lift, stops work when conditions change, and makes sure defects are reported and acted on.
• The operator inspects the crane, knows the load chart, refuses lifts that are unsafe and has the final say on whether the crane will lift.
• Riggers and signallers do their tasks as trained and stop the lift if they see a problem.
• Every worker stays out of the fall zone and the swing radius unless they have a job there.

Ontario's Act also gives every worker the right to refuse unsafe work, and a crane operator who doubts that a lift is safe has both a legal right and a professional duty to refuse. Alberta's code puts this directly into section 66: if the operator has doubts about the safety of a lift, it must stop until the condition is made safe.

Checking qualifications in practice

A qualification check takes a few minutes and should happen before the crane is set up, not after the first lift. For the operator, ask to see the certificate of qualification or provisional certificate and check the name, the trade and the expiry date. Skilled Trades Ontario keeps a public register that can confirm whether a certificate is valid, and other provinces have similar services. Then ask the employer for the record of training on this particular crane, because a certificate shows trade competence, not familiarity with a specific model and its controls.

For riggers and signallers, ask the employer what training they have had, who assessed them and when, and whether it covers the kind of rigging and signalling in the plan. A worker who has rigged steel beams for years may never have rigged a load with an offset centre of gravity using a spreader beam. If a lift plan names people who have not been assessed for its specific demands, the lift waits until they have been, or until people who have been are found.

Keep a simple record of the check: names, documents seen, dates and any gaps found. It protects the workers, the employer and the supervisor, and it is the first thing an inspector will ask for after an incident.
