This twenty-fifth edition of the Canadian Electrical Code, Part I, was approved by the Committee on the Canadian Electrical Code, Part I, and by the Regulatory Authority Committee at their June 2020 meetings. This twenty-fifth edition supersedes the previous editions, published in 2018, 2015, 2012, 2009, 2006, 2002, 1998, 1994, 1990, 1986, 1982, 1978, 1975, 1972, 1969, 1966, 1962, 1958, 1953, 1947, 1939, 1935, 1930, and 1927.
This edition contains important revisions to many Sections.

Several important changes appear in Section 26, including 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.
New requirements in support of climate change adaptation appear in several Sections of the Code. Section 22 now contains a new Subsection for farm buildings housing livestock, as well as revised Rules for equipment in Category 1 and 2 locations.

- clarification has been provided on impedance grounded system operation under fault condition in Section 10;
- new requirements for electrical equipment installed near roof decking systems have been added in Section 12;

- Table 19 has been completely reorganized, simplified, and shortened;
- Annexes A.1 and A.2 of Appendix A have been removed and are now hosted online;
- Appendix E has been deleted; and
- the Index has been deleted in conformance with CSA Group's drafting and editorial requirements.
