EDSR | Ontario Regulation 22/04

Amendments to Ontario Regulation 22/04 Effective October 1, 2017

On October 1, 2017, new serious incident reporting requirements come into effect as a result of amendments made to Electrical Distribution Safety Regulation 22/04. These changes follow extensive consultation by both the Electrical Safety Authority and the Ministry of Government and Consumer Services over the last two years.

The key changes are:

  • Mandatory reporting requirements for Local Distribution Companies (LDCs) to include all serious electrical safety incidents involving meters except in cases of events of force majeure.
  • The definition of “worker” in the regulation has been amended to align with the Occupational Health and Safety Act.
  • A definition for force majeure has been added.
      • A requirement for LDCs to assist ESA in investigations of serious electrical incidents of LDC-owned assets.
      • Updated references to existing National Standards that LDCs are currently following

The updated Guideline for Serious Electrical Incident Reporting and a revised Serious Electrical Incident Report Form is available here. ESA will work closely with each LDC to support them in meeting their compliance.

Frequently Asked Questions – Amendments to EDSR 22/04

Ontario Regulation 22/04 Background

In early 2004 changes in regulation advanced public electrical safety with the approval and introduction of Ontario Regulation 22/04 addressing Electrical Distribution Safety.

Ontario Regulation 22/04 - Electrical Distribution Safety establishes objective based electrical safety requirements for the design, construction, and maintenance of electrical distribution systems owned by licensed distributors.

The Electrical Distribution Safety Regulation establishes a standard for safety performance and offers distribution companies options for achieving compliance. Specifically, the regulation requires the approval of equipment, plans, specifications and inspection of construction before they are put into service - but provides local distribution companies with a number of options to obtain these approvals. The ESA together with industry representatives have developed a series of guidelines to help clarify and interpret the Regulation.

Electrical Distribution Safety Regulation


Why is Regulation 22/04 important in Ontario?

This regulation ensures electrical safety, and the excellent safety record of the electrical distribution industry, will be maintained in the new de-regulated electricity market.

What drove the development of Regulation 22/04?

Section 113 (1) of the Electricity Act provides the statutory framework within which the Electrical Safety Authority (ESA) operates. Within the legislation ESA may, with the approval of the Lieutenant Governor in Council, introduce regulations related to public electrical safety matters in the Utility sector.

In the fall of 2000 ESA wrote to the provincial government recommending a review of the electrical safety regulatory framework that applied to electric generation, transmission, and distribution. In this review, ESA evaluated the approach taken in other jurisdictions and industries, including the Ontario natural gas industry, the availability of technical standards for reference in regulations, and held discussions with 13 key stakeholders (approximately 42 individuals) to obtain their feedback and input. The following provides a summary report and the full report presented to the Government with respect to electrical distribution systems and public electrical safety requirements.

Summary Report

Safety Standards Report

How was Regulation 22/04 developed?

Following recommendations from the Electrical Safety Authority (ESA) to establish a new regulation governing the appropriate electrical safety standards and oversight of the licensed electricity distributors in Ontario a public consultation process was initiated.

A consultation process was introduced to invite stakeholders to review and provide comments on ESA’s proposal for the development of regulation, requisite standards, and corresponding compliance processes as they apply to electricity distribution and public electrical safety.

Consultation was gathered through a structure of Discussion Groups that considered formal proposals or requests for revisions and amendments to utility regulations and standards, including the compliance processes.
