APPRENTICESHIP PROGRAM

An apprenticeship training program consists of on-the-job and in-school training. The Registrar of Skilled Trades Ontario, under the authority of section 14 of the Building Opportunities in the Skilled Trades Act, 2021, has set the hours of apprenticeship training for the trade Plumber at 9,000 (approximately five years), which consists of 8,280 hours on the job work experience and 720 hours of in-school training. These hours are consistent with apprentice training hours previously set out in regulation under the Trades Qualification and Apprenticeship Act, R.S.O 1990.

ON-THE-JOB TRAINING

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.

IN-SCHOOL TRAINING

A Plumber apprenticeship includes three levels of theoretical training, which includes but is not limited to instruction in:

  • workplace safety, rigging, and hoisting
  • pipe and fitting materials, pipe supports and hangers
  • tools and piping methods
  • plumbing fixtures, appliances and equipment
  • properties of water and heat transfer
  • trade calculations, construction drawings and job specifications
  • codes, regulations and standards
  • drainage, venting and waste piping systems
  • sewage disposal systems
  • water distribution systems

Depending on the training delivery agency, in-school training may be available in one of the following ways:

  • block release (full-time, for a set number of weeks)
  • day release (one day per week from September to June)
  • part-time (night-school programs)
  • alternative delivery (online, correspondence, etc.)
