Understanding the precise requirements for Canadian electrical code receptacle spacing is fundamental for both safety and functionality in any residential or commercial build. The Canadian Electrical Code, formally known as the Canadian Standards Association (CSA) C22.1, provides the definitive regulations that govern all electrical installations across the country. While many professionals are familiar with rules regarding circuit capacity and grounding, the specific mandates concerning how far outlets must be placed from one another and from other fixtures are equally critical. These rules ensure that power is accessible where needed and that extension cords, a common source of hazards, are minimized.
Horizontal Spacing Requirements in Living Areas
In living rooms, bedrooms, and similar habitable spaces, the Code mandates that receptacles must be located no further than six meters (approximately 20 feet) apart along the wall line. This rule is designed to ensure that you can plug a device into almost any point in the room without needing to stretch a cord across a walkway or furniture. Furthermore, if a wall is longer than two meters (about 6.5 feet), a receptacle must be installed at least one meter (39 inches) from the end of that wall. This prevents the scenario where a large piece of furniture blocks the only outlet, forcing you to use a dangerous extension cord.
Kitchen and Utility Zone Specifications
Kitchens and utility areas have stricter requirements due to the high concentration of small appliances and water sources. Countertop receptacles must be spaced no more than 2400 mm (approximately 8 feet) apart to ensure accessibility behind immovable appliances like refrigerators or stoves. Additionally, any countertop space that is 300 mm (12 inches) or wider requires its own dedicated receptacle. This often means that wide sections of counter, such as those adjacent to a sink or prep area, cannot share a single outlet, significantly reducing the risk of overloading a single plug.
Dimensional Rules for Bathrooms and Special Areas
Bathrooms present unique challenges due to the presence of water and the frequent use of hairdryers and other personal care devices. The Canadian Electrical Code stipulates that at least one receptacle must be located within 300 mm (12 inches) of the centerline of a mirror that is permanently installed under a medicine cabinet. This ensures that shavers or hair straighteners can be used without relying on extension cords. In laundry rooms, at least one receptacle must be provided within 300 mm of the folding surface of a washer or dryer, and a dedicated circuit is usually required for heavy-duty appliances.

Hallways and Corridors
Hallways are often overlooked, but the Code addresses them specifically to maintain safety flow throughout a home. If a hallway is wider than 1.8 meters (approximately 6 feet), a receptacle must be installed at each end. This ensures that if there is a need for temporary lighting or a vacuum cleaner at either end of the passage, power is readily available without running cords across the entire width of the hallway. In narrower hallways, the general six-meter rule for living areas applies.
When planning your electrical layout, it is essential to remember that these rules apply to the final finished surface. This means that if you are installing baseboards or trim, the measurement is taken from where the wall cover ends. Deviating from these established spacings can result in failed inspections, costly rework, and potentially void insurance claims in the event of a fire. Adhering to these distances ensures your wiring system remains efficient, accessible, and compliant with the highest safety standards in Canada.
