Ontario's mobile crane apprenticeship under its official name, Hoisting Engineer, Mobile Crane Operator 1 (339A): a compulsory trade, 6,000 hours over four levels, Grade 10 entry, and the Red Seal exam, distinct from tower crane and Operator 2.
Applies in: Ontario
In Ontario, a mobile crane operator apprentice registers under the trade name Hoisting Engineer, Mobile Crane Operator 1, code 339A. Find a crane company or contractor willing to sponsor you, register the apprenticeship with Skilled Trades Ontario, and work through four levels that combine 5,520 hours on the job with 480 hours of technical training, 6,000 hours in total. At the end, the trade has a certifying exam, and passing it earns a Certificate of Qualification with the Red Seal endorsement. Unlike most Ontario trades, this one is compulsory: you must be registered or certified to practise it in Ontario.
Ontario classifies trades as compulsory or voluntary, and this trade's label decides the whole shape of the path. Hoisting Engineer, Mobile Crane Operator 1 is compulsory in Ontario. That means the apprenticeship is not an optional credential on top of legal work; registration as an apprentice, and later certification, is what makes the work legal. Skilled Trades Ontario states that if you are in a compulsory trade, your name will appear on the Skilled Trades Ontario Public Register. The practical consequence is timing: do not operate a mobile crane over 16,000 pounds on an Ontario site while unregistered on the assumption that experience alone covers you. It does not.
The scope is set by regulation. The scope of practice for hoisting engineer, mobile crane operator 1 includes maintaining and operating mobile cranes capable of raising, lowering, or moving any material that weighs more than 16,000 pounds. A mobile crane, for this purpose, is a mechanical device or structure incorporating a boom, capable of moving in the vertical and horizontal plane and of raising, lowering, or moving a load suspended from the boom by a hook or rope, mounted on a mobile base or chassis, including a telescoping or articulated boom. Equipment used exclusively for firefighting, and automotive wreckers and tow trucks used to clear wrecks and haul vehicles, are excluded. If the machine you will run sits below that weight line or outside that definition, a different branch or a different credential may apply, and the sponsor and Skilled Trades Ontario are the people to confirm it with before you register.
The sponsor comes first. Skilled Trades Ontario is clear that an apprenticeship begins when you sign a Training Agreement with a sponsor and register it, and that finding a sponsor is the key first step. A sponsor can be an individual employer, such as a crane rental company or a heavy contractor, or a group of employers, such as a union or consortium.
The application steps, from Skilled Trades Ontario's start-an-apprenticeship page, are:
The program totals 6,000 hours: 5,520 hours of on-the-job training and 480 hours of technical training across four levels. The apprenticeship programs chart marks the trade as hours-based, which means you must complete the on-the-job training for the entire duration of the prescribed hours. Keep the logbook current and make sure recorded hours match what the sponsor reports, because in an hours-based trade unrecorded hours are hours you may have to work again.
The in-school training covers four levels of theoretical training, including workplace safety, crane types and terminology, crane systems and components, wire rope and rigging, lift planning for general, hydraulic, and conventional cranes, crane assembly, set-up and dismantle procedures, hydraulic and conventional crane operations, specialized hoisting operations, transporting a crane, and crane maintenance. Delivery varies by training delivery agency: block release full-time for a set number of weeks is one of the formats Skilled Trades Ontario names. The through-line of the classroom work is calculation: planning a lift means calculating crane capacity and determining load weights before the lift, not estimating them on the day.
What the trade does, in Skilled Trades Ontario's own description, is operate cranes or draglines to lift, move, position, or place machinery, equipment, and other large objects at construction or industrial sites, ports, railway yards, surface mines, and other similar locations. The operator performs pre-operational inspections, prepares and transports cranes, assembles and dismantles them, plans lifts, sets up, positions, and stabilizes the crane before the lift, and performs rigging procedures. The work is outdoors, at height, and weather-dependent, and the safety stakes of a miscalculated lift are the reason the trade is compulsory.
Hoisting Engineer, Mobile Crane Operator 1 has a certifying exam. Skilled Trades Ontario issues a Certificate of Apprenticeship when you complete the apprenticeship program, and a Certificate of Qualification when you pass the certifying exam. Because the trade is part of the Interprovincial Red Seal Program, passing the exam also carries the Red Seal endorsement, which is the credential recognized in every province and territory. Job Bank confirms the same national picture for crane operators: the Red Seal endorsement is available to qualified mobile crane and tower crane operators on successful completion of the interprovincial Red Seal examination.
Experienced operators who never registered have a parallel door. The Trade Equivalency Assessment lets experienced tradespeople document equivalent qualifications or experience and seek the Certificate of Qualification without completing the apprenticeship. The assessment requires verifiable evidence of competency against the Training Standard and experience at least equal to the required training time, which for this trade is 6,000 hours. Check the current Trade Qualifier application guide before relying on that route, because the evidence bar is documentary, not a matter of asserting years on the tools.
Do not register under the wrong branch. Operator 2 and tower crane are separate trades with separate hours and separate exams, and the Red Seal position differs between them. Do not operate over the 16,000-pound line unregistered in Ontario; the compulsory classification means registration is the permission, not a bonus. Do not confuse the crane certificate with the road licence: moving a mobile crane on public roads may require a separate provincial driving licence, and the class was not verified for this guide. And do not let months of crane work go unrecorded. In an hours-based trade, the logbook and the sponsor's hour reports are the record, and gaps in that record are gaps in the program.
Hoisting Engineer, Mobile Crane Operator 1, trade code 339A. Crane operator is the common name, and Job Bank groups the occupation under crane operators, NOC 72500. The Ontario name matters because there are three separate hoisting engineer trades: Mobile Crane Operator 1 (339A), Mobile Crane Operator 2 (339C), and Tower Crane Operator (339B). Registering under the wrong code puts you in the wrong program with the wrong hours, so use 339A for mobile cranes over 16,000 pounds.
The program is 6,000 hours: 5,520 hours of on-the-job training, described by Skilled Trades Ontario as approximately three years, and 480 hours of technical training, described as three months across four levels. It is hours-based, which means you complete the full prescribed on-the-job hours rather than progressing on competency sign-off alone. The calendar time depends on how steadily crane work is available with your sponsor, and crane work is seasonal and project-based, so steady hours are not guaranteed in every year.
Yes, and this is the sharpest difference from most Ontario trades in this family. The Skilled Trades Ontario chart lists Hoisting Engineer, Mobile Crane Operator 1 (339A) as compulsory. In a compulsory trade, you must be a registered apprentice or a certificate holder to practise the trade in Ontario, and your name appears on the Skilled Trades Ontario Public Register. Job Bank agrees for NOC 72500: mobile crane operator trade certification, for specified types of cranes, is compulsory in Ontario, among other provinces. Do not carry the voluntary status of another trade into this one.
Grade 10 is the academic entry grade listed in the Skilled Trades Ontario chart and trade report for 339A. Skilled Trades Ontario also requires apprentices to be at least 16 years old, to have legal permission to work in Canada, and to have a sponsor in Ontario. In practice the sponsor decides whether to take you on, and crane employers weigh driving record, reliability, and comfort working at height and outdoors in all weather. A high school diploma is the safer starting point even where Grade 10 is the legal minimum, because the in-school training runs on load charts, crane capacity calculations, and load-weight calculations.
Capacity, crane type, and program length. Operator 1 (339A) covers mobile cranes capable of raising, lowering, or moving material weighing more than 16,000 pounds, over 6,000 hours, with a Red Seal endorsement. Operator 2 (339C) covers hydraulically controlled mobile cranes lifting more than 16,000 pounds but no more than 30,000 pounds, over 1,000 hours, with no Red Seal endorsement. Tower Crane Operator (339B) is a separate 3,000-hour program, also compulsory and also Red Seal. If the work you want is tower cranes on high-rise sites, 339A is the wrong registration even though both are called crane operator.
Job Bank states that mobile crane operators may require a provincial licence to drive mobile cranes on public roads. This guide does not name a licence class, because no class was verified on an Ontario page at the time of writing, and the class depends on the crane's configuration and weight. Ask the sponsoring employer which licence class its cranes require on the road, and confirm the requirement with the Ministry of Transportation before you assume a car licence is enough. The crane certificate and the road licence are separate documents.
Where a figure could not be verified on a Skilled Trades Ontario or Job Bank page at the time of writing — any examination fee, any wage figure, and the road-licence class for driving a mobile crane — this guide says so and points to the Skilled Trades Ontario and Ministry of Transportation pages instead of carrying a secondary source's figure. Check those pages before you pay anything or plan around a number.
