For over 90 years, CSA Group has worked with regulators, consumers, manufacturers, and the electrical industry to develop standards that improve safety and reliability of the electrical system as well as electrical products for consumers and businesses. We also continue to support improved energy performance and sustainability, including renewable energy through new and updated codes and standards.
Today our portfolio of more than 700 standards, many referenced in regulation, includes standards for Energy Efficiency, Renewable Energy and the Canadian Electrical Code Parts I, II and III. These are critical resources that guide electrical safety and performance for the systems and products we use daily across the country.
CSA Group also supports the timely adoption of these standards by routinely working with federal, provincial and territorial Authorities Having Jurisdiction (AHJs). We also work with industry associations such as the Canadian Electricity Association, the Association of Home Appliance Manufacturers Canada, and Electro Federation Canada to ensure our codes and standards continue to address the needs of industry.

The first edition of the Canadian Electrical Code was published in 1927.[1] The current (25th) edition was published in April of 2021. Code revisions are now scheduled on a three-year cycle. The Code is produced by a large body of volunteers from industry and various levels of government. The Code uses a prescriptive model, outlining in detail the wiring methods that are acceptable. In the current edition, the Code recognizes that other methods can be used to assure safe installations, but these methods must be acceptable to the authority enforcing the Code in a particular jurisdiction.
The Canadian Electrical Code serves as the basis for wiring regulations across Canada. Generally, legislation adopts the Code by reference, usually with a schedule of changes that amend the Code for local conditions. These amendments may be administrative in nature or may consist of technical content particular to the region. Since the Code is a copyrighted document produced by a private body, it may not be distributed without copyright permission from the Canadian Standards Association.
The Code is divided into sections, each section is labeled with an even number and a title. Sections 0, 2, 4, 6, 8, 10, 12, 14, 16, and 26 include rules that apply to installations in general; the remaining sections are supplementary and deal with installation methods in specific locations or situations. Some examples of general sections include: grounding and bonding, protection and control, conductors, and definitions. Some examples of supplementary sections include: wet locations, hazardous locations, patient care areas, emergency systems, and temporary installations. When interpreting the requirements for a particular installation, rules found in supplementary sections of the Code amend or supersede the rules in general sections of the Code.
The Canadian Electrical Code does not apply to vehicles, systems operated by an electrical or communications utility, railway systems, aircraft or ships; since these installations are already regulated by separate documents.
The Canadian Electrical Code is published in several parts: Part I is the safety standard for electrical installations. Part II is a collection of individual standards for the evaluation of electrical equipment or installations. (Part I requires that electrical products be approved to a Part II standard) Part III is the safety standard for power distribution and transmission circuits. Part IV is set of objective-based standards that may be used in certain industrial or institutional installations. Part VI establishes standards for the inspection of electrical installation in residential buildings.
Technical requirements of the Canadian Electrical Code are very similar to those of the U.S. National Electrical Code. Specific differences still exist and installations acceptable under one Code may not entirely comply with the other. Correlation of technical requirements between the two Codes is ongoing.
Several CE Code Part II electrical equipment standards have been harmonized with standards in the USA and Mexico through CANENA, The Council for the Harmonization of Electromechanical Standards of the Nations of the Americas (CANENA) is working to harmonize electrical codes in the western hemisphere.
In response to industry demand, CSA has developed Part IV of the Canadian Electrical Code, consisting of two standards CSA C22.4 No. 1 "Objective-based industrial electrical code" and CSA C22.4 No. 2 "Objective-based industrial electrical code - Safety management system requirements". These standards are intended for use only by authorized industrial users and would not apply, for example, to residential construction. These standards do not prescribe specific solutions for every case but instead give guidance to the user on achievement of the safety objectives of IEC 60364. Since it is less prescriptive, the OBIEC allows industrial users to use new technology not yet represented in the CE Code Part II. Use of this OBIEC is restricted to industrial and institutional users who have a safety management program in place and the engineering resources to implement the regulations. It is intended that users of the OBIEC will maintain safety while using methods that will reduce the installation cost of large industrial plants, for example, in the petrochemical business.[2][3]
Electricity powers the world, but the equipment and systems that utilize it can present shock and fire hazards. This is, of course, nothing astonishing, as electrical installations have not only been carefully managed for the past century, but they have been safely guided by codes and standards that provide users with the utmost contemporary knowledge.
Electrical codes lay out guidelines that help facilitate the safe installation of electrical wiring and equipment. In the United States, the NFPA 70 National Electrical Code fulfills this need. In Canada, it is the Canadian Electrical Code. Among the numerous similarities shared between these documents in their purpose, they both follow a similar three-year revision cycle.
In Canada, adhering to the CE Code goes beyond just following safe practices. The Canadian Electrical Code is generally adopted by legislation, with some changes needed to amend the code for circumstances particular to the local body. In these instances, the governmental requirements supersede the stipulations of the code, so it is crucial to know your local rules.
As 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 Code. Furthermore, redundant or out-of-date requirements, such as the rules for open wiring, were removed. Some specific changes to the 2021 Canadian Electrical Code include:
The previous edition of the Canadian Electrical Code, CSA C22.1-2018, was also a substantial revision, including over 260 updates in total. Its changes included significant alterations to sections on residential/housing, renewable energy, grounding and bonding, and tamper resistant receptacles, as well as the addition of power over ethernet guidelines and these specific updates:
Which way is the right way for our electrical outlet? This is the reason for asking. I now have an apartment in my sons house which was finished in the last twelve months. The house itself is not a new one. Anyway, I bought one of those plug in lights with a sensor on it. This was for my entrance as I have two steps down and it would be ideal for coming in in the evenings, but when I plugged it in it was upside down and it didn't work to shine on my two steps. I checked my sons outlets and they are the other way up. So I contacted the builder and asked them shy they had put all my electrical plugs upside down. They told me this was the correct way with the code here in Newfoundland. I also bought a couple of those plug in air cleaners and of course they don't work either, as after a few days the plastic inserts drop out onto the floor. The writing on the outlet in my bathroom is also upside down. So what I want to know is why are these small electrical things made with the thicker prong on one side not fitting my outlets the right way up. Is it a Canadian code change or just a Newfoundland one? Even find it awkward to plug in appliances, as you have to hold the plug with the earth at the top and it always wants to go the other way. It doesn't make sense to me.
Oh, I agree with you that this is so frustrating. All the plugs in my house are up-side-down as well, except for a few that I have turned over. I have heard a few contractors in both Ontario and Quebec insist that you have to have the ground wire up -- while all the manufacturers of flat appliance cords and plug in the wall gadgets accept the standard that the ground wire should go down. This whole question was probably less important before we started having a lot of gadgets designed to plug directly into the outlets, not to mention the flat microwave cords which now are physically strained sticking straight up in the air because they are designed to follow the general standard of the ground wire down -- giving the electrical outlet a smiley face.
So what does the code say? The Canadian Electrical code says nothing, although three codes ago there was a requirement for putting the outlets in horizontally in mobile homes. The argument was to keep the cords from hanging over each other. But that has since been removed from the code.
