About
Boilermakers fabricate, assemble, install, maintain and repair boilers, pressure vessels, storage tanks and similar large metal structures. The work often takes place in industrial plants, power stations and construction sites. It calls for strong welding, fitting, rigging and blueprint-reading skills.
Each province and territory with a boilermaker apprenticeship issues its own certificate of qualification. If you also pass the interprovincial Red Seal exam, you earn the Red Seal endorsement on that certificate. The endorsement is recognised in every province and territory, so it helps you move between jobs and regions across Canada.
How to get it
Find an employer and register as an apprentice
Most people start by getting hired by an employer who will sponsor them. You then register as an apprentice with your provincial or territorial apprenticeship authority.
Complete on-the-job training
You work under a certified boilermaker and log your hours in the trade. This is where you build most of your practical skills, such as welding, fitting and rigging.
Attend technical training
Apprentices take blocks of classroom and shop training at an approved training provider. These cover trade theory, safety, codes and blueprint reading.
Have your hours and training signed off
Once you finish the required work experience and technical training, your apprenticeship authority confirms you are ready to write the certification exam.
Pass the exam and receive your certificate

The exam
The Red Seal Boilermaker exam is a written, multiple-choice test. It covers the main parts of the trade, including safety, rigging, welding, fabrication, installation and repair. Most people prepare by reviewing their technical training notes and practice questions over a few weeks to a few months.
