The skilled trades offer something rare: a path to a well-paid career where you earn while you learn, with no university debt. The way in is the apprenticeship. But the system can look confusing from the outside — sponsors, training agreements, levels, exams. This guide breaks it down into plain steps.
A quick note: the apprenticeship system is administered by Skilled Trades Ontario (STO), and rules and processes change. Confirm current details on the STO website before acting.
What an apprenticeship actually is
An apprenticeship is structured trades training where you learn by doing. In Ontario, the split is roughly 80% paid on-the-job work learning from skilled professionals, and about 20% classroom-based learning at a college, union training centre, or similar. You get paid while you learn, and apprenticeships generally take 2 to 5 years depending on the trade. Typically you work for a year or more, then take 8 to 12 weeks of in-class training, and that cycle repeats until you finish.
Step 1: Decide on a trade
Ontario has more than 140 skilled trades. Before committing, it helps to know whether your target trade is compulsory (you must be a registered apprentice or certified to legally work — like electrician or plumber) or non-compulsory (certification is optional but valuable — like welder or carpenter). This affects how essential the full path is.
Step 2: Find a sponsor (the key first step)
This is the step that gates everything else. A sponsor is the employer (or group of employers, such as a union or consortium) responsible for making sure you get all your training. You don’t need to take special courses or be in school to start — you need someone willing to hire and train you. Ways to find a sponsor include asking your school’s guidance office about programs like OYAP, checking with colleges and union training centres, and applying directly to employers in your trade.
Step 3: Sign and register a Training Agreement
Once an employer agrees to sponsor you, you complete a Registered Training Agreement (RTA). If you’re 18 or older you can apply through the Skilled Trades Ontario Portal; if you’re 16–17 you submit a paper application (a parent or guardian signs). Once registered, STO issues the agreement for you and your sponsor to sign, and when STO receives it signed, your apprenticeship officially begins. There’s no fee to register as an apprentice.
Step 4: Work and log your hours
The bulk of your apprenticeship is on the job. You work under a journeyperson who signs off your skills, and you keep a logbook tracking your competencies and hours. Keeping that logbook current matters — it’s your proof of progress.
Step 5: Complete your in-class levels
Each apprenticeship requires roughly 3 to 4 levels of in-class technical training that support the on-the-job learning. Invitations for in-school training are sent by email based on your registration date — STO sends them well ahead of the program start, so watch for them and respond promptly. Missing a class invitation can delay your level and your pay increases.
Step 6: Finish and certify
When you’ve completed your hours and in-class levels, STO issues a Certificate of Apprenticeship. If your trade has a certifying exam, you can then write it to earn your Certificate of Qualification (C of Q), which proves you have all the skills for the job. For trades in the Red Seal program, passing the Red Seal exam lets you work across Canada.
Money help while you train
Because you’re paid as an apprentice, you’re earning throughout — but there are also grants and supports. Federal and provincial incentives have existed for apprentices (some, like the Apprenticeship Completion Grant, have closed, while others continue), the Canada Apprentice Loan can help with technical-training costs, and the CRA’s Tradesperson’s Tools Deduction lets you deduct part of the cost of eligible tools. Check current grants and incentives, as these change.
A simple summary
- Pick your trade. 2. Find a sponsor (the hard part). 3. Sign and register your Training Agreement. 4. Work and log hours. 5. Complete your in-class levels. 6. Finish, then write your C of Q (and Red Seal if offered).
The bottom line
An Ontario apprenticeship is a paid, multi-year path that combines work and school and ends in a recognized certification — often without a dollar of tuition debt. The single hardest step is landing a sponsor, so building basic skills and networking hard is the move. Everything after that is logging hours, attending your levels, and certifying.
