Persons who have received permission (or a permit) by the authority having jurisdiction to undertake electrical installations regulated under the previous 2018 Canadian Electrical Code, Part I (twenty-fourth edition) prior to February 1, 2022, will be considered in compliance with the Safety Codes Act. Installations permitted on or after February 1, 2022, are required to conform to the new 2021 edition of the Canadian Electrical Code, Part I. Unless an unsafe condition exists or would exist in the opinion of the authority having jurisdiction, electrical installations in progress should not be required to be updated to the new codes and result in undue hardship or cost. Questions regarding unusual situations should be directed in writing to the local authority having jurisdiction:

For area classification requirements at oil and gas facilities permitted or constructed prior to February 1, 2019, the use of the “Code for Electrical Installations at Oil and Gas Facilities”, published by the Safety Codes Council, is permitted.
