Ontario's Pattern Maker apprenticeship, trade code 443A: Grade 12 entry, three levels, 7,280 hours on the job plus 720 hours of in-school training, voluntary status, and the certifying exam. Foundry patterns, not textile patterns.
Applies in: Ontario
In Ontario, a Pattern Maker apprentice registers under the trade name Pattern Maker, code 443A, two words. Find a foundry, casting shop, or pattern shop willing to sponsor you, register the apprenticeship with Skilled Trades Ontario, and work through three levels that combine 7,280 hours on the job with 720 hours of in-school training, 8,000 hours in total. At the end, the trade has a certifying exam, and passing it earns a Certificate of Qualification. There is no Red Seal endorsement for this trade. Skilled Trades Ontario does list a Pattern Maker apprenticeship, so this slot ships: the kill condition in the batch slate, no apprenticeship listed, does not apply. The name needs settling first, because the wrong patternmaker is a real occupation with a different registration.
The name is exact, and the spacing matters. The Ontario trade name is Pattern Maker, code 443A. The batch slate wrote Patternmaker as one word. That one-word spelling is also the Job Bank title for textile patternmakers, a different occupation entirely. Use Pattern Maker, two words, whenever a form asks for the trade, and use code 443A to remove any remaining doubt.
The first trap is the textile confusion. A Pattern Maker 443A reads and interprets complex engineering drawings, pattern drawings, and work process documentation; designs and creates foundry patterns and core boxes from metal, wood, plastic, and polystyrene for parts and components cast from metal; builds precision pattern tooling using wood and metal cutting machines and equipment, including saws, drills, grinders, lathes, mills, and electrical discharge machines; and performs work-in-process measuring and checking with specialised and precision tools and equipment. That is Skilled Trades Ontario's own description. A textile patternmaker creates master patterns for garments and other textile, leather, or fur products. The shops, materials, and machines do not overlap. A posting that mentions fabric, garments, or dress patterns is not advertising this apprenticeship, however similar the title looks.
The second trap is the group the trade sits in. Nationally, metal patternmakers sit inside the Tool and die makers group, National Occupational Classification 72101, alongside tool and die makers and mould makers. Group membership does not transfer group facts. Tool and Die Maker 430A is a Red Seal trade with its own program. Pattern Maker 443A is not. The chart records no Red Seal endorsement for 443A, and this guide does not claim one. Likewise, Job Bank's statement that patternmaking trade certification is available but voluntary in Ontario describes the voluntary character of certification; the Ontario certification itself comes through Skilled Trades Ontario on completion of this program and the certifying exam, as the trade information page states.
The voluntary point itself matters. Pattern Maker is a non-compulsory trade in Ontario. Nobody needs a licence or certificate to make patterns in this province, and you can work in the trade without ever registering. The apprenticeship is not permission to work. It is structured training, a training standard of signed-off skills, a Certificate of Apprenticeship, and the path to the certifying exam and the Certificate of Qualification. Because the trade is non-compulsory, the Certificate of Qualification does not have to be renewed, and a certificate holder's information does not appear on the Skilled Trades Ontario Public Register. Do not assume the Ontario rule travels with you. Job Bank records patternmaking certification as voluntary in Ontario only, among the jurisdictions it names. If another province is in your plans, check its listing for this exact occupation before you move.
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 foundry, a casting shop, or a pattern shop, 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 8,000 hours: 7,280 hours of on-the-job training and 720 hours of in-school training across three levels. The June 2026 chart publishes the split and the level count without a calendar length or an in-school subject list, so this guide states neither. What is fixed is the split and the level count from the chart, and the scope of work from the trade description: reading complex drawings, designing and creating foundry patterns and core boxes, building precision pattern tooling on cutting machines, and measuring and checking work in progress with precision tools.
The rhythm is work, then a block of in-school training, then work again. Depending on the training delivery agency, in-school training may run as block release, day release, part-time, or alternative delivery such as online or correspondence, the delivery forms Skilled Trades Ontario lists for its apprenticeship programs generally. Attend when invited through the training system, keep your logbook current, and make sure your recorded hours match what your sponsor reports. Pattern work punishes careless measurement in a way that shows up at the foundry: a pattern a fraction out leaves a casting that no machining can honestly rescue, which is why the training standard skills around drawing interpretation and in-process checking exist.
Pattern Maker 443A 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 non-compulsory, that certificate does not have to be renewed, and the holder's information does not appear on the Public Register. And because the chart records no Red Seal endorsement for this trade, passing the exam earns the Ontario Certificate of Qualification only, with no national endorsement attached. Anyone promising a Red Seal endorsement for 443A is describing a different trade.
Experienced pattern makers 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 application guide requires verifiable evidence of competency against the Training Standard and experience at least equal to the required training time, 8,000 hours for this trade, supported by work experience verifications from references who know the work first-hand. Confirm the current fee and the evidence list in the Trade Qualifier application guide before you apply.
Do not enrol in a garment patternmaking course expecting it to count toward this trade. The textile occupation is a different registration under a different National Occupational Classification, and its courses teach fabric patterns, not foundry patterns. Do not claim a Red Seal endorsement for 443A, and do not assume the tool and die maker Red Seal statement covers this trade. Do not confuse this trade with Mould Maker 431A or with Tool and Die Maker 430A. Mould makers make the moulds; tool and die makers make tools, dies, jigs, and fixtures; pattern makers make the patterns and core boxes the foundry casts from. The work overlaps at the machine shop door and separates at the product. Do not let months of shop work go unrecorded. Unrecorded hours are hours you may have to work again, so keep the logbook signed and the hours submitted. And do not pay for a course that promises the certificate on its own. The certificate comes through Skilled Trades Ontario on completion of the program and the certifying exam, not through a private training provider alone.
Pattern Maker, trade code 443A. That is the Ontario trade name exactly as Skilled Trades Ontario lists it in the apprenticeship programs chart and on the trade information page, spelled as two words. The batch slate spelled it as one word, Patternmaker, and Job Bank uses that one-word spelling for a different occupation, textile patternmaking. Do not follow either of those spellings on a registration form: put down Pattern Maker 443A. The national occupation name is Tool and die makers, National Occupational Classification 72101, a group that also includes metal patternmakers. When a form asks for the trade, the code 443A is what separates this trade from Mould Maker 431A and from Tool and Die Maker 430A.
No. A Pattern Maker 443A designs and creates foundry patterns and core boxes from metal, wood, plastic, and polystyrene for parts and components cast from metal, and builds precision pattern tooling on wood and metal cutting machines. A textile patternmaker creates master patterns for garments, footwear, and other textile, leather, or fur products, under National Occupational Classification 53125. The two occupations share a word and almost nothing else: different materials, different machines, different shops, and different registrations. If a course or posting talks about garment patterns, computer-assisted garment patternmaking, or fabric, it is not this trade. If it talks about castings, core boxes, and foundry work, it is.
The program is 8,000 hours: 7,280 hours of on-the-job work experience and 720 hours of in-school training, delivered across three levels. This guide states no calendar length, because the June 2026 chart, the source used for the hours split, publishes hours and levels without a calendar length. Job Bank describes the patternmaking route inside the tool and die makers group as usually requiring completion of an apprenticeship or college program in patternmaking, without giving a Pattern Maker program length of its own. The hours are the fixed part; the calendar time follows how steadily the foundry or pattern-shop work comes and when the in-school blocks run.
No to both, and the two answers need keeping apart. Pattern Maker 443A is non-compulsory in Ontario. You do not need to be a registered apprentice or a certificate holder to make patterns in this province, though registration is still how you get the structured training, the Certificate of Apprenticeship, and the certifying exam. Because the trade is non-compulsory, the Certificate of Qualification does not have to be renewed, and a certificate holder's information does not appear on the Skilled Trades Ontario Public Register. Separately, the June 2026 chart records no Red Seal endorsement for 443A. Job Bank says a Red Seal endorsement is available to qualified tool and die makers, but that statement belongs to the tool and die maker trade, not to this one. Do not carry it across: a Pattern Maker certificate carries no Red Seal endorsement.
Grade 12 is the academic entry grade listed in the Skilled Trades Ontario apprenticeship programs chart for Pattern Maker 443A. 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. Job Bank describes completion of secondary school as usually required for the tool and die makers group nationally, which matches the Grade 12 chart entry. Treat the diploma as the standard a sponsor will expect: the work runs on complex engineering drawings, pattern drawings, and work process documentation, so technical reading, measurement, and precision checking are worth arriving with.
First find a sponsor, an employer or group sponsor responsible for your training, such as a foundry, a casting shop, or a pattern shop. Then apply: if you are 18 or older, apply online through the Skilled Trades Ontario Portal; if you are 16 or 17, or you cannot apply online, complete the paper Application for Apprenticeship Training, signed by you, a parent or guardian if you are under 18, and your sponsor, and submit it to Skilled Trades Ontario. Once approved, you and your sponsor sign a Training Agreement, which registers you as an apprentice, and you receive a Registered Apprentice Wallet Card. Experienced pattern makers can also seek certification through the Trade Equivalency Assessment, which requires documented competency against the Training Standard and experience at least equal to the required training time, recorded as 8,000 hours for this trade in the Trade Qualifier application guide. Check that guide before relying on the route, because the evidence bar is documentary and any fee can change.
Where a figure could not be verified on a Skilled Trades Ontario or Job Bank page at the time of writing — any calendar length for the program, any in-school subject list, any certifying examination fee, any Trade Equivalency Assessment fee, and any wage figure — this guide says so and points to the Skilled Trades Ontario trade page instead of carrying a secondary source's figure. Check that page before you pay anything or plan around a date. No figure in this guide comes from the textile patternmaking occupation, whose Job Bank page describes a different trade.
