2021 Ontario Electrical Saftey Code

The Electrical Safety Authority (ESA) would like to advise that the Government has approved the regulatory amendment to adopt the 2021 Ontario Electrical Safety Code (OESC), which comes into effect on May 5, 2022. 

The new Code will be available for order in December 2021. The hardcopy of the Code book will be available for $223, as well as a PDF-version available for $199. These prices will include free access to the bulletins on CSA Community of Interest website over the whole period of the Code cycle. Once purchased, the PDF-version can be accessed immediately, while the hardcopy versions will be available for delivery in late January 2022.

ESA is partnering with the CSA Group to offer the Code book and all ESA bulletins, which provide important updates and interpretations, together for one price in a searchable, digital format for $199 — accessible on smart phones, tablets and desktops and compatible with Windows and iOS. This version will be available in Summer 2022.
