What electrical code changes mean for homeowners in Vancouver
Canadian Electrical Code in BC: Key Changes from 2018 to 2025
(And What They Mean for Your Home)
The Canadian Electrical Code (CEC) sets the national safety standard for all electrical installations in Canada. As licensed electricians working across Vancouver and the Lower Mainland every day, our team at Kato Electrical tracks every update — because every permit we pull must comply with the current code in effect in BC.
This guide covers the most significant CEC changes from the 2018 Edition (in effect January 1, 2020) through to the 2024 Edition (adopted in BC on March 4, 2025) — and what each change means for homeowners and businesses planning electrical work.
If you are planning a renovation, panel upgrade, or EV charger installation, understanding these changes will help you ask the right questions — and protect your property. Contact our licensed electricians →
Why the Electrical Code Matters for BC Homeowners
Every time a licensed electrician pulls a permit for your home or business — whether for a panel upgrade, EV charger installation, or electrical renovation — the work must comply with the version of the BC Electrical Code in effect at the time the permit was issued.
Technical Safety BC enforces the BC Electrical Code under the Safety Standards Act. Staying current with code is not just a professional obligation — it directly affects the safety, insurability, and resale value of your property. Work done without permits or inspections may not meet code, creating liability for homeowners.
2025 Update: BC Adopts the 2024 Canadian Electrical Code
Effective March 4, 2025, British Columbia officially adopted the 2024 Canadian Electrical Code, Part I, 26th Edition (CSA C22.1-24). This is the edition that applies to all electrical permits issued in BC from that date forward.
All work performed under permits issued after March 4, 2025 must comply with the 2024 edition without exception.
Key themes of the 2024 CEC include:
- Stronger support for electric vehicle charging infrastructure and energy management systems
- Updated rules for residential energy storage — removing restrictions on lithium batteries in dwelling units
- New standards for renewable energy systems, including rapid shutdown requirements for solar (photovoltaic) systems
- Enhanced GFCI protection for outdoor extension cords used in damp locations
- Refined bonding requirements for pools, hot tubs, and spas
- Updated arc flash protection for workers performing energized electrical work

Key Changes from the 2018 Canadian Electrical Code (In Effect January 1, 2020)
The 2018 CEC introduced 260 revisions. Below are the most significant changes affecting residential and light commercial properties — with a plain-language explanation of what each one means if you are planning electrical work on your home.
Power over Ethernet (PoE) — New Safety Requirements
What changed: The 2018 edition introduced new requirements (Rules 16-300 through 16-350) for Power over Ethernet cabling. As PoE power levels approached 100W and cables were often bundled together, heat buildup became a safety concern requiring specific installation rules.
Neutral Conductor Required at Every Switch Location
What changed: The 2018 code now requires an identified conductor (previously called a "neutral") at every manual or automatic control location. The previous 2015 code permitted a simple two-wire switch loop.
Bonding and Grounding — Simplified and Reorganized
What changed: Section 10 was condensed from 15 pages to 8, with clearer specifications for grounded and ungrounded systems. Two tables were combined into one, simplifying how electricians size bonding conductors.
Arc Fault Circuit Interrupters (AFCI) — Expanded Protection
What changed: The 2018 code tightened exemptions from AFCI protection. Circuits supplying smoke alarms, carbon monoxide alarms, and bathrooms — previously exempt — are now covered. AFCI protection also now extends to existing branch circuits that are extended due to renovations or additions.
Disconnecting Means for LED Luminaires
What changed: The 2015 code required disconnecting means for fluorescent ballasts. The 2018 code extended this to LED drivers exceeding 150V to ground with double-ended lamps — reflecting the industry-wide shift from fluorescent to LED technology.
Tamper-Resistant Receptacles — Expanded to More Occupancy Types
What changed: The 2015 code required tamper-resistant (TR) receptacles in dwelling units and child care facilities. The 2018 code expanded this to all areas where children may be present — hotel guest rooms, preschools, and elementary education facilities.
GFCI Protection Expanded to Bathroom Heaters and Controls
What changed: The 2018 code introduced GFCI protection requirements for electric heating devices and controls near sinks, showers, or tubs — mirroring the existing GFCI rules for receptacles in wet areas.
Electric Vehicle Energy Management Systems (EVEMS) — Formally Recognized
What changed: The 2018 code formally recognized EVEMS — systems that intelligently manage EV charging loads to stay within existing service capacity. Previously, EV charger loads were added to load calculations at 100% of their rated capacity, often forcing expensive service upgrades.
Electric Shock Drowning — Enhanced GFCI for Marinas & Docks
What changed: Section 78 was extensively updated to require GFCI and Ground Fault protection for branch circuits and feeders in marinas, floating piers, and docking facilities — following significant research on electric shock drowning.
Kitchen Wall Receptacles — Simplified Requirements
What changed: The 2015 code required kitchen wall receptacles to be on a separate dedicated circuit. The 2018 code removed this requirement, recognizing that many kitchens now function as general living areas.
Maximum Continuous Load — Now Required to Be Field Marked
What changed: New Sub Rule 2-100(4) requires a caution label on electrical equipment indicating the maximum permitted continuous load — communicating this to future maintenance personnel, inspectors, and installers.
Continuous Load Calculations — Simplified
What changed: Rule 8-104 was simplified, replacing a complex and inconsistently applied set of sub-rules with two clear requirements based on whether the switch or breaker is marked for 100% or 80% continuous operation.
The 5% Overload Rule — Eliminated
What changed: Sub Rule 8-106(1) previously permitted calculated loads to exceed conductor ampacity by 5%. This rule was eliminated in 2018 due to conflicts with other rules and inconsistent field application.
Refrigerator Circuit Requirements — Clarified
What changed: The 2015 code required a separate circuit for each refrigerator receptacle. The 2018 code clarified that a dedicated circuit only applies to the mandated refrigerator receptacle in kitchens — and a single circuit can supply more than one refrigerator receptacle.
