The 25th edition of the Canadian Electrical Code, CSA C22.1-2021 has undergone numerous alterations from the 2018 revision of the standard.
New requirements in support of climate change adaptation were added throughout several Sections of the latest CE Code edition. Furthermore, redundant or out-of-date requirements, such as the rules for open wiring, were removed.

Specific changes to the 2021 edition of Canada's National Electrical Code include:

  • Section 64, Renewable energy systems, energy production systems, and energy storage systems, features a new subsection governing the installation of energy storage systems and rules for functionally-grounded renewable energy systems.
  • Section 26, Installation of electrical equipment, includes a new requirement for ground fault circuit interrupter protection for all 15 A and 20 A receptacles located outdoors within 2.5 m of grade, among other changes.
  • Section 22, Locations in which corrosive liquids, vapours, or excessive moisture are likely to be present, now contains a new Subsection for farm buildings housing livestock, as well as revised Rules for equipment in Category 1 and 2 locations.
  • The definition for “Voltage — Low voltage” was revised.
  • Clarification was provided on impedance grounded system operation under fault condition in Section 10, Grounding and bonding.
  • New requirements were added for electrical equipment installed near roof decking systems to Section 12, Wiring methods.
  • Load calculations and equipment layout for recreational vehicle lots were updated in Section 72, Mobile home and recreational vehicle parks.
  • Table 19, Conditions of use for insulated conductors and cables other than flexible cords, portable power cables, and equipment wires, was completely reorganized, simplified, and shortened.
  • Annexes A.1, CSA Canadian Electrical Code, Part II safety standards for electrical equipment and A.2, Other Canadian safety standards for electrical equipment, of Appendix A, Safety standards for electrical equipment, were removed and are now hosted online at
  • Appendix E, Dust-free rooms, was removed.

These few examples only partially detail the entirety of the adjustments and additions made to the 2021 Canadian Electric Code. Our training course will review these changes, and others, in more detail.
