For every apprentice working in this trade, the employer is required to maintain a 1:1 ratio of apprentices to journeypersons on-site and must ensure that the apprentice is directly supervised by a certified journeyperson in the trade.

What are the entrance requirements?

High School Apprenticeship Program (HSAP): Begin your apprenticeship training in high school. A minimum age of 16 years in required.

General Admission: A Grade 12 or equivalent high school academic standing is required including recommended courses in Math and Science. If you do not hold a high school diploma, you can also qualify as an Access Program Trainee (formerly Mature Student). Prior Learning Recognition and Assessment may be required.

Trades Qualification: If you are experienced in the trade, but do not hold a Certificate of Qualification, you may become a certified journeyperson based on years of proven industry experience and successful completion of the Certification Examination. A Trades Qualification Application and trade specific work experience form must be submitted. Trades professionals whose entrance readiness is less than that required, must take appropriate upgrading.

For additional details on entrance requirements and how to begin your apprenticeship or obtain certification, see section on "How to Start".

Do I get a certificate?

When you finish all your required apprenticeship levels of practical experience and technical training, you write an interprovincial examination.
