Ontario's 310S apprenticeship: 7,220 hours, compulsory trade rules, finding a sponsor shop, apprentice wages, and the Red Seal exam.
Applies in: Ontario
An automotive service technician apprenticeship in Ontario is an employer-first path into the 310S trade: the full-ticket licence for diagnosing, repairing, and maintaining cars and light trucks. Get hired by a dealership, independent shop, or fleet maintenance department willing to sponsor you, register the training agreement with Skilled Trades Ontario, then work about four years of paid on-the-job hours (6,500 of them) interleaved with three classroom levels (720 hours total). Pass the certifying exam, earn the Certificate of Qualification with its Red Seal endorsement, and you can work the trade anywhere in Canada.
Ontario classifies trades as compulsory or voluntary, and the classification changes everything. Automotive Service Technician (310S) is compulsory. That means you cannot legally practise the trade in Ontario without one of three things: a Registered Training Agreement (the apprentice route), a Provisional Certificate of Qualification, or a full Certificate of Qualification, and your name has to show up on the STO Public Register. Unlicensed wrenching on other people's cars for money is not a grey area; it is outside the law. The compulsory label is also the reason the path is so fixed: sponsor first, register, log hours, write the exam. Our Red Seal guide explains the exam's national portability.
The Ontario auto trades are a family, so check you are in the right one before registering:
The current STO apprenticeship-programs chart lists Grade 12 as the academic standard for 310S, three in-school levels, and 7,220 total hours. Treat Grade 12 as the floor: the classroom blocks run on electrical theory, electronics, diagnostics, and applied shop math. College apprenticeship pages add the practical prerequisites: at least 16 years old (18 in the standard cases sponsors handle), legal permission to work in Canada with a valid social insurance number, and a sponsor in Ontario. Note that the sponsor comes before the application; you apply to STO once you have the job offer. STO's official starting-apprenticeship page walks through the registration sequence, and the STO contact line (647-847-3000, toll-free in Ontario 1-855-299-0028) answers paperwork questions.
This is the step that starts the clock. Your hours only count once a Registered Training Agreement ties you to a sponsoring employer, and the agreement is drafted by the Ministry after your sponsor comes on board:
A useful shortcut: pre-apprenticeship motive power programs at Ontario colleges teach tool handling, shop safety, and first-level material before you start the sponsor hunt. A pre-apprenticeship certificate does not replace a sponsor, but it answers the question every service manager asks: "will this person slow my techs down?" The sponsor hunt is a job search in every sense: our job hunting guide walks through Job Bank, Canadian resume conventions, and the NOC codes (72410 for automotive service technicians) you will use on applications.
The official numbers from STO's 2026 apprenticeship chart: 6,500 hours of on-the-job work experience plus 720 hours of in-school training, for 7,220 hours total over about four years. The classroom runs in three levels covering work practices, engine systems, electrical and electronics, fuels and emissions, drivetrains, suspension, steering, and brakes. Delivery varies by college: Loyalist describes three eight-week full-time blocks or a day-release option of one day a week across the levels.
Two notes that matter. First, each level ends with exams you must pass to advance; the hours alone do not promote you. Second, you are an employee the whole way through. Apprentices are paid by their employer while learning on the job, and Employment Insurance covers apprentices during full-time technical training, so apply before your school block starts since processing takes time.
Plan these alongside the apprenticeship, not after it:
School is the cheap part of this trade. Algonquin College's GM-ASEP stream publishes 2026/2027 costs of $400 tuition per level plus $300 in incidental fees per level, plus textbooks, safety footwear, and your tools. You are earning a wage between blocks, and the funding picture is straightforward:
With the hours and school levels done, you write the certifying exam. Passing earns the Certificate of Qualification from Skilled Trades Ontario, and because 310S is an Interprovincial Red Seal trade, the exam carries the Red Seal endorsement: the national stamp that lets you work the trade anywhere in Canada without re-certifying. Ontario employers post the full band openly: licensed techs at dealerships and independents advertise roughly $30 to $40 per hour, against the Job Bank median of $30.00 per hour for the occupation in Ontario (updated June 2026). Specialty lanes (dealer master techs, EV service) climb higher. And if you ever want the business side, our trades comparison guide compares the startup shape across the trades.
About four years. Skilled Trades Ontario sets the 310S program at 7,220 hours total: 6,500 hours of on-the-job work experience plus 720 hours of in-school training across three levels. Your sponsor's licensed technician signs off competencies in the training-standard logbook as you go, and each school level has exams to pass before you advance.
Yes. Skilled Trades Ontario confirms 310S is compulsory, which means you must hold a Registered Training Agreement, a Provisional Certificate of Qualification, or a Certificate of Qualification to practise the trade in Ontario, and your details must appear on the STO Public Register. Working uncertified on 310S work is not an option.
The current STO apprenticeship-programs chart lists Grade 12 as the academic standard for 310S. You also need to be at least 16 years old (colleges commonly say 18, with limited exceptions at 16), have legal permission to work in Canada with a valid social insurance number, and, critically, have a sponsoring employer in Ontario before you apply through Skilled Trades Ontario.
310S (Automotive Service Technician) is the full general-repair trade for cars and light trucks: diagnostics, engines, electrical, brakes, steering, suspension, and drivetrains. 310B (Auto Body and Collision Damage Repairer) is the separate body-work and painting trade. 310T (Truck and Coach Technician) is the heavy side: transport trucks and coaches. All three are compulsory in Ontario. This guide walks the 310S path.
This is a job search, not an application. Dealership service departments, independent repair shops, chain shops like TIRECRAFT (which runs named 310S apprentice intakes), and fleet maintenance departments all sponsor apprentices. The GM ASEP stream at Algonquin College is a formal route: GM requires you to be sponsored by a GM dealer before training starts. Walk in with a clean driving record, basic tools, and evidence you will show up; sponsors hire reliability first.
Apprentice pay starts well below the certified rate and climbs as you progress. For scale, Job Bank puts the median wage for automotive service technicians in Ontario at $30.00 per hour (updated June 2026), with recent employer postings for licensed techs at dealerships and independents running roughly $30 to $40 per hour, and specialty roles like Tesla service technicians advertising $44 to $58 per hour at the senior end.
Tuition is modest relative to college diplomas. Algonquin College's 2026/2027 GM-ASEP stream lists tuition of $400 per level plus a $300 incidental fee per level, and you also pay for textbooks, safety footwear, and your own basic hand tools. You earn a wage between school blocks. The Canada Apprentice Loan covers up to $4,000 per period of technical training, interest-free, and Employment Insurance covers apprentices during full-time school blocks.
After finishing the hours and school levels, you write the certifying exam; passing earns the Certificate of Qualification from Skilled Trades Ontario. Because 310S is an Interprovincial Red Seal trade, the exam carries the Red Seal endorsement, the stamp that lets you work the trade anywhere in Canada without re-certifying. Our Red Seal guide explains the endorsement mechanics and the trade-qualifier route for experienced workers.
Yes, through the Ontario Youth Apprenticeship Program (OYAP). OYAP lets high school students begin accumulating apprenticeship hours and, in some cases, in-school training while still in school. Colleges also list 16 as the minimum with limited exceptions, though 18 is the standard sponsors look for. It is the cheapest head start available: hours banked before graduation count toward the 7,220.
Effectively, yes. Employer postings for technicians routinely list a personal toolbox with basic hand tools as a requirement, and Algonquin's ASEP stream lists safety footwear and supplies as the student's responsibility. Nobody expects a first-year to arrive with a full box, but a solid basic set signals you take the trade seriously and removes a hiring friction.
