To work in many areas of the building and renovation contractors in Ontario there are Ontario trade license requirements specific to the province. Each province in Canada has its own licensing requirements for specific areas of building and other trade services. A specific construction license is not needed for employment in Ontario. But this may be not the case in the big cities. For example, in order to enter into a written contract with a building contractor in Toronto that contractor has to have a valid City of Toronto license. In addition roofers, carpenters, bricklayers, concrete workers, waterproofing and insulators have to have a construction license. In addition, to put in kitchens and bathrooms in Toronto all trades except flooring contractors and window installers need a valid City of Toronto license.
In Hamilton, Ontario a license is required for building maintenance and repair as well. So the rules on how to get a license depend on where you live in the province.
To apply for some trades in every part of Ontario all workers must have a Certificate of Qualification, or “C of Q.” The trades include plumbers, electricians, septic installers, gas fitters, sheet metal worker and refrigeration and air conditioning. A “C of Q.” will certify that these tradespersons have taken the apprenticeship program and have passed the provincial qualification exams that assure their knowledge of the trade in which they will be working.
In order to take the provincial qualification exam each person must show they have the knowledge and experience in the particular trade. This includes:
Electricians normally work in both domestic and commercial buildings such as new homes, shopping malls and hotels. Their job entails follow the blueprints to assemble the components, connect the areas to power source and test the electrical fixtures. In addition they also work on alarm systems, exterior lighting, communication writing and heating plants. Unlike general electricians construction and maintenance electricians generally work on a project-by-project basis.
As with many other trades in Ontario the Construction and Maintenance Electrician must complete a five-year apprenticeship that includes 90% on-the-job training and 10% in-school training. An apprentice usually earns minimum wage. Once they receive their Certificate of Qualification or “C of Q,” he or she is deemed a "journeyperson."
In Ontario an Electrical Contractor License is required to engage in electrical work.
A Master Electrician License may be issued to an individual who has performed at least 3 years experience in the electrical trade in Ontario such as:
A refrigeration and air conditioning mechanic works on cooling or heating-and-cooling systems that are used in most settings: residential, commercial, industrial or institutional. They work for companies that design, build, install and service a variety of refrigeration and air conditioning systems.
However, the residential air conditioning mechanics can only work on systems that use no more than 240V single-phase power with a maximum circuit capacity of 60 amps and a capacity for maximum cooling of five tons (60,000 BTUs). They must also go through an apprenticeship program.
In Ontario plumbers must have a license to work in construction or installing fittings and fixtures where the distribution and use of water within a building is involved. This also includes the safe removal of used water from grey and black water in the home to storm drains. Kitchens and bathroom renovations will require licensed plumbers. In addition, licensed plumbers are also required for the wholesale selling of plumbers products but this is not a prerequisite.
Apprentices in the plumbing trade serve a 9,000-hour training period with 720 of these hours in the classroom. Admission to the program requires the applicant o have at least a Grade 10 education and be at least 16 years of age.
