How to Become a Plumber in Canada

Plumbers install, repair, and maintain the water, drainage, venting, and fixture systems in homes and commercial buildings. It is a compulsory, licensed trade, so unlike some trades you cannot work unsupervised without the ticket, which is exactly why licensed plumbers are in demand. Here is the path from getting started to a licensed journeyperson.

Understand the trade

Job Bank classifies this trade under NOC 72300, Plumbers. It is a dedicated, single-occupation code, and it is distinct from steamfitters and pipefitters, from sprinkler-system installers, and from HVAC and refrigeration mechanics. If you install and service plumbing systems, this is your trade.

Apprentice, and earn the licence

• Register a plumber apprenticeship with a licensed plumbing or mechanical contractor, combining paid on-the-job hours with technical training
• Complete the apprenticeship and pass the certificate of qualification exam, for example Ontario's 306A plumber licence
• Plumbing is a compulsory trade in Ontario and most provinces, so the licence is required to work unsupervised, not optional

Get the Red Seal and the add-ons

• A Red Seal endorsement is available on passing the interprovincial exam, which enables mobility across Canada
• A gasfitter ticket is a common add-on that widens the work you can take
• Backflow prevention certification and specialized tickets add value

Build the skills

• Service diagnostics and callout work, rough-in and finish, and code compliance
• Blueprint and drawing reading, and backflow prevention
• Residential, commercial, and industrial experience, which lifts your pay

Land your first role

Apply to plumbing and service contractors, mechanical contractors, and construction firms. Because plumbers are in a documented shortage, sign-on and referral bonuses are common, so emphasize your licence, your Red Seal, and any service or industrial experience. Set up a job alert on a board built for the trade so new openings reach you before they fill.
