Electrical System Safety Assessment Checklist

Electrical System Safety Assessments can be performed by a Licensed Electrical Contractor (LEC) using resources1 from the former ElecCheck program. LECs may use the following Electrical System Safety Assessment Checklist (a list of electrical wiring and/or devices) when evaluating a home’s electrical system:


  • The resources provided on this page are for Licensed Electrical Contractors use and for information purposes. Licensed Electrical Contractors should rely on their own knowledge, experience and skill in any use they choose to make of these materials.
  • The “Electrical System Safety Assessment” is not an exhaustive summary of the requirements of the Code or of what is necessary to assess electrical safety at any particular location. 
  • Provision of these resources does not constitute legal or technical advice for any property, or at all.  
  • In carrying out any electrical assessment or undertaking electrical work, no one should hold themselves out as an electrical inspector or as an agent or representative of the Electrical Safety Authority (ESA).  
  • ESA makes no warranties with respect to these materials including their fitness for a particular purpose and assumes no responsibility for the accuracy, completeness or use of these materials.   

An Electrical System Safety Assessment is a review of a home's electrical wiring and/or devices to identify potential electrical hazards that could lead to a fire and/or shock. A homeowner may be request an Electrical System Safety Assessment for several reasons, including:

  • Resale of property
  • To conform to local by-laws (for homes built prior to 1976)
  • Fire department referrals (Used when non-compliant non hazardous electrical code issues are identified and need to be addressed.)

If electrical deficiencies are identified (i.e., an electrical installation or condition that does not comply with the Ontario Electrical Safety Code) during an assessment, the LEC will work with the homeowner to correct the deficiencies. The electrical work needs to be reported to ESA by filing a notification of work.
