How to become a licensed plumber: compulsory vs voluntary provinces, entrance requirements, finding a sponsor, the hours (Alberta 6,240, Ontario 9,000, BC 6,300), wages, costs, and the Red Seal exam.
Applies in: across Canada
A plumbing apprenticeship is an employer-first path: get hired by a plumbing contractor willing to sponsor you, register the training agreement with your province's apprenticeship authority, work four to five years of on-the-job hours under a journeyperson mentor while completing classroom blocks, then write the certification exam. In seven provinces the trade is compulsory, so you must be registered or certified to do the work at all. In the rest it is voluntary, but employers still expect the certificate. The Red Seal exam at the end is the stamp that lets you work the trade anywhere in Canada.
This changes everything about urgency. Job Bank (NOC 72300) divides Canada into two camps:
Either way, the apprenticeship is the same shape: hours, school, exam. The difference is whether you can skip it (legally you can in the voluntary provinces; practically, don't).
Every province sets a minimum, and employers routinely set a higher bar. The official minimums in the three biggest provinces:
Treat the minimum as a floor. Classroom training is heavy on applied math (drainage calculations, pipe sizing, pressure and flow), and apprentices who arrive with upgraded math fail out less often. If your school math is rusty, upgrading before you start is cheaper than repeating a level.
This is the step that starts the clock. In every province, your hours only count once a registered agreement ties you to a sponsoring employer:
A shortcut worth knowing: college pre-employment plumbing programs (12 to 24 weeks, depending on the school) teach you Level-1 material and basic tool skills, and graduates can challenge the first-level exams in some provinces. A pre-employment certificate does not replace a sponsor, but it answers the question every contractor asks: "will this kid slow my journeyperson down?" Landing the sponsor is a job search in every sense: our job hunting guide walks through Job Bank, Canadian resume conventions, and the NOC codes you'll use on applications.
The program is four to five years of paid work interleaved with classroom blocks. The official numbers, province by province:
| Province | Program | Total hours |
|---|---|---|
| Ontario | 3 levels (306A) | 9,000 (8,280 on-the-job plus 720 in-school) |
| Alberta | 4 periods | 6,240 (1,560 work hours plus 8 classroom weeks per period) |
| British Columbia | 4 levels | ~6,300 work-based training hours |
Two notes on the table. First, each level or period ends with exams you must pass to advance; the hours alone don't promote you. Second, Alberta's plumber program carries a bonus: it includes Gasfitter–Class B certification: Alberta plumber apprentices who finish the program receive two journeyperson certificates (Plumber and Gasfitter–Class B) and can write both interprovincial exams.
Classroom blocks cost money (a few thousand dollars per school period depending on the institution), but you are earning a wage between school blocks, and the funding picture is straightforward:
Confirm the current tuition with your training institution before you plan the year — figures move, and colleges publish per-period fee schedules.
Apprentices are paid as a rising share of the journeyperson rate — your pay climbs with each period or level, and your provincial apprenticeship authority sets the current minimums, so verify before you accept an offer. For scale: Job Bank puts the Alberta journeyperson plumber median at $30.00 per hour. First-year apprentice pay is a fraction of the journeyperson rate at your company, and it rises as you progress — by the final level, experienced apprentices are earning near-journeyperson money while the certificate is one exam away.
After completing all hours and all classroom blocks, you write the certification exam for your journeyperson (Certificate of Qualification) status in your province. The optional but valuable next stamp is the Red Seal endorsement: pass the interprovincial Red Seal exam and you can work the trade in any other province or territory without re-certifying — worth writing while the material is fresh.
Certification opens the trade, not just the job. Common next moves:

Fees, wages, and program details move — verify current figures with your provincial apprenticeship authority and the training institution before you enrol.
Four to five years, depending on the province: Alberta runs 4 periods of 1,560 hours (6,240 total) with 8 classroom weeks per period; Ontario runs 3 levels totalling 9,000 hours (8,280 on-the-job plus 720 in-school); BC runs 4 levels with about 6,300 work-based training hours. You earn a wage the whole way.
In seven provinces — Nova Scotia, Prince Edward Island, New Brunswick, Quebec, Ontario, Saskatchewan, and Alberta — trade certification for plumbers is compulsory: you must be a registered apprentice or certified journeyperson to do the work and use the title. In Newfoundland and Labrador, Manitoba, BC, and the three territories it is voluntary — you can legally work without the certificate, but employers, insurers, and customers still expect it. (Job Bank, NOC 72300.)
It depends on the province. Ontario requires Grade 10 as the minimum for the 306A plumber program. Alberta requires English 20-2, Math 20-3, and Science 10 — or a GED/CAEC pass or an AIT entrance exam. In BC, employers hiring apprentices typically look for Grade 12 completion. Check your province's apprenticeship authority for the current minimum.
Yes, in practice. Your on-the-job hours only count when you are registered with your province's apprenticeship authority and working under a sponsoring employer — Ontario requires a registered training agreement, Alberta requires an Apprenticeship Education Agreement signed through MyTradesecrets, and BC requires registration with SkilledTradesBC plus an employer sponsor. Finding the sponsor is a job search, not an application.
The classroom blocks cost money — a few thousand dollars per school period depending on the institution — but you are earning a wage between school blocks. The Canada Apprentice Loan offers up to $4,000 per period of technical training, interest-free, with no payments until you finish or leave (everywhere except Quebec). Employment Insurance covers apprentices during full-time technical training. Note: the old federal Apprenticeship Incentive Grant ($1,000) and Completion Grant ($2,000) closed on March 31, 2025 — older guides still describe them as live.
Apprentices are paid as a rising share of the journeyperson rate, so pay climbs with each period or level; your provincial apprenticeship authority sets the current minimums. For scale, Job Bank puts the Alberta journeyperson plumber median at $30.00 per hour — you can expect first-year apprentice pay to be a fraction of the going journeyperson rate at your company, rising as you progress.
The interprovincial Red Seal endorsement is optional, but it is the credential that lets you work as a plumber anywhere in Canada without re-certifying. You earn it by passing the interprovincial Red Seal exam after completing your province's apprenticeship program. Alberta is a bonus case: its plumber program includes Gasfitter–Class B, so you graduate with two journeyperson certificates (Plumber and Gasfitter–Class B) and can write both Red Seal exams.
In Alberta, yes: the Registered Apprenticeship Program (RAP) lets you split time between school and a paid apprenticeship position, banking on-the-job hours and high-school credits simultaneously. Pre-employment plumbing programs at colleges are another way in — they make you a much easier hire, but they do not replace the sponsoring employer your province requires.
The shape is the same — employer sponsor, registered agreement, on-the-job hours plus classroom blocks, journeyperson exam, optional Red Seal. The numbers differ: Alberta's electrician program is 4 periods of 6,120 hours with the compulsory-trade rules tightly enforced, while plumber certification is voluntary in some provinces. Our electrician apprenticeship guide walks the Alberta path step by step if you are comparing the two trades.
