The Mechanical Techniques - Construction Boilermaker Apprenticeship program prepares students for a career in the rewarding and extensive boilermaker field. Boilermakers build, install and maintain boilers, tanks and vessels-huge steel containers with thick, solid walls that hold liquids and gases which must withstand a great deal of pressure for long periods of time. The Construction Boilermaker apprenticeship requires about four years including 6,600 workplace hours and 720 in-school hours of post-secondary training. One must pass an exam to receive a Certificate of Qualification with journey person status, which includes an Inter-Provincial Trade Certification (Red Seal).

External Recognition

Upon completing an apprenticeship, the Ministry of Labour, Training and Skills Development will issue an individual a Certificate of Apprenticeship. Upon passing the trade’s certification examination and meeting the College’s registration requirements, the individual may apply to become certified and registered as a journeyperson in the trade. Certain tasks that may be performed by a Construction Boilermaker legally require the individual to be certified by the Technical Standards and Safety Authority. In Ontario, the trade is part of the Interprovincial Red Seal Program-the national standard for the trade across Canada-under the title Boilermaker:

Admission Requirements

  • Ontario Secondary School Diploma (OSSD) or equivalent, mature student status
  • Prospective students must be in good standing/registered as Apprentices with the Ministry of Labour, Training and Skills Development 

Additional Information

An apprenticeship involves practical training provided on-the-job by a skilled worker, or trainer. The skills or competencies to be developed are set out by the trade’s apprenticeship training standard and are recognized by the industry as being essential to the practice of the trade.

As these essential skills are developed, the apprentice’s sponsor or trainer signs the relevant sections of the training standard to indicate that the apprentice has met the individual training objectives by demonstrating the skills required of a skilled worker, or journeyperson, in the trade.

To advance through the levels of the apprenticeship program, an individual must have completed all of the units outlined in the previous level (i.e., complete Level 1 before advancing to Level 2).
