What are the Alberta code requirements for GFCI placement in a bathroom renovation?

Alberta Building Code requires GFCI protection for all bathroom electrical outlets and specific lighting circuits, with strict placement rules to ensure safety in wet environments.

Under the Alberta Electrical Code (which adopts the Canadian Electrical Code with provincial modifications), all bathroom electrical installations must meet stringent safety requirements due to the high risk of electrical shock in wet environments. GFCI (Ground Fault Circuit Interrupter) protection is mandatory for virtually all bathroom electrical components, and placement rules are designed to keep electrical devices away from water sources while maintaining functionality.

All bathroom outlets must have GFCI protection — no exceptions. This includes outlets near the vanity, outlets for hair dryers or electric razors, and any outlet within the bathroom space. The GFCI protection can be provided by a GFCI outlet itself or by a GFCI breaker at the electrical panel. Most Calgary electricians prefer GFCI outlets because they're easier to test and reset, and homeowners can identify the problem location immediately if a trip occurs.

Outlet placement follows the "3-foot rule" — no electrical outlets are permitted within 3 feet (1 metre) of a bathtub or shower stall. This means you cannot install an outlet on the wall directly beside your bathtub or inside the shower area. However, outlets are required within 3 feet of the bathroom sink for practical use (hair dryers, electric toothbrushes, shavers). This creates a specific zone around the vanity where outlets are both required and permitted. In practice, most bathroom outlets are installed on the wall beside or above the vanity mirror, typically 42-48 inches above the floor.

Lighting circuits have specific GFCI requirements depending on the fixture type and location. Light fixtures installed directly above bathtubs or shower stalls must be rated for wet locations and may require GFCI protection depending on the specific installation. Exhaust fan circuits typically require GFCI protection. Heated floor systems (radiant in-floor heating) must have GFCI protection — this is non-negotiable and applies to both electric mat systems and cable systems installed under tile floors.

Switches do not require GFCI protection but have their own placement rules. Light switches must be installed outside the 3-foot zone around bathtubs and showers. You cannot install a light switch on the wall directly beside your bathtub where you could reach it while bathing. Most bathroom light switches are installed near the bathroom door, outside the wet area.

Dedicated circuits are often required for bathroom electrical loads. The Alberta Electrical Code requires that bathroom outlets be supplied by a dedicated 20-amp circuit that serves only bathroom outlets — this circuit cannot power outlets in other rooms. Large electrical loads like heated floors, exhaust fans, or multiple high-wattage light fixtures may require separate dedicated circuits. A 1500-watt heated floor system, for example, requires its own 15-amp circuit with GFCI protection.

Special considerations for Calgary renovations include the fact that older Calgary homes (pre-1980s) often lack adequate electrical service for modern bathroom loads. Adding heated floors, multiple outlets, and high-CFM exhaust fans may require electrical panel upgrades. Calgary's extreme temperature swings can stress electrical connections, so all bathroom electrical work should use high-quality components rated for temperature cycling.

Permit and inspection requirements mean that all new electrical circuits, outlet additions, and GFCI installations require an electrical permit through the City of Calgary. The electrical work must be performed by a licensed electrician and inspected by an Alberta electrical inspector before the circuit can be energized. Attempting DIY electrical work in bathrooms is particularly dangerous due to the wet environment and is illegal under Alberta regulations.

Practical installation tips include installing GFCI outlets with LED indicator lights so you can easily see if the device has tripped. Test GFCI outlets monthly using the test and reset buttons — a GFCI that won't reset or won't trip during testing should be replaced immediately. In Calgary's dry climate, static electricity can occasionally cause nuisance GFCI trips, but frequent tripping usually indicates a wiring problem that requires professional diagnosis.

When planning your bathroom renovation, discuss electrical requirements early with your contractor. Adding outlets, upgrading circuits, or installing heated floors affects the project timeline and budget. Electrical rough-in happens after plumbing rough-in but before insulation and drywall, so electrical planning must be finalized before demolition begins.
