Do HVAC contractors need an electrical contractor licence?

It depends on the work they are doing and the qualifications of the people doing the work.

Exemptions include: 

  • Refrigeration and air conditioning systems mechanics or residential air conditioning systems mechanics authorized under the Ontario College of Trades and Apprenticeship Act. 
  • Work done on electrical components of appliances by someone authorized under Ontario Regulations 210/01 (Oil and Gas Pipeline Systems), 211/01 (Propane Storage and Handling) and 215/01 (Fuel Industry Certificates) under the Technical Standards and Safety Act. 

Anyone engaged in this type of work should contact Skilled Trades Ontario and Technical Standards & Safety Authority to confirm the limitations. An HVAC contractor doing electrical work outside of the scope of theses qualifications requires an electrical contractor licence.
