To be a plumber, pipefitter or gas fitter, you must have some high school education or a high school diploma.
To gain trade certification, you must finish an apprenticeship program, or have a combination of experience and high school, college or industry courses. You may need trade certification in the province/territory where you'll work.
Qualified tradespersons may also obtain interprovincial (Red Seal) trade certification, which provides job mobility throughout the country.
Many recent entrants have a trade/vocational certificate.
