What is the minimum distance an electrical outlet must be from the edge of a bathroom sink according to the Ontario code?

In Ontario, the Canadian Electrical Code (CEC) requires that any receptacle installed in a bathroom be located at least 1 metre (approximately 3 feet 3 inches) from the edge of a bathtub or shower stall — but there is no specific minimum distance required between a receptacle and a bathroom sink basin itself. What the code does require, without exception, is that every receptacle in a bathroom be GFCI-protected, regardless of its location in the room.

This distinction matters practically. The 1-metre rule applies to tubs and showers because full immersion creates the highest electrocution risk. Sinks present a different risk profile, so the code addresses them through mandatory GFCI protection rather than a fixed distance requirement. A GFCI (Ground Fault Circuit Interrupter) receptacle cuts power in milliseconds when it detects a ground fault — such as a hair dryer falling into a sink full of water — which is why this protection is non-negotiable in every Ontario bathroom.

What This Means for Your Bathroom Layout

In practical terms, your electrician will position bathroom receptacles based on a combination of code requirements, common sense safety, and functionality. The standard placement for a vanity receptacle is on the wall beside the mirror, typically 6 to 12 inches to the side of the vanity and 36 to 48 inches above the finished floor. This keeps it convenient for daily use (hair dryers, electric shavers, curling irons) while maintaining safe clearance from water splashing out of the basin.

Most GTA bathrooms — particularly the compact 5x8-foot layouts common in post-war bungalows across Scarborough, North York, and Etobicoke — have a single GFCI receptacle beside the vanity mirror. Larger master ensuites often have two receptacles, one on each side of a double vanity. In condo bathrooms, the receptacle location is frequently constrained by the existing conduit routing through the concrete structure, which limits how far it can be repositioned without significant electrical work.

The GFCI Requirement Is the Critical Point

Every bathroom receptacle in Ontario must be GFCI-protected — this is enforced under the Ontario Electrical Safety Code (which adopts the CEC with provincial amendments) and inspected by the Electrical Safety Authority (ESA). GFCI protection can be provided either by a GFCI receptacle at the outlet itself, or by a GFCI breaker protecting the entire bathroom circuit upstream at the panel. Either method satisfies the code requirement.

If you are renovating a bathroom in an older Toronto home — particularly pre-war homes in the Annex, Riverdale, or East York — there is a reasonable chance the existing bathroom receptacle is not GFCI-protected and may be on an ungrounded two-prong circuit. Any bathroom renovation that involves electrical work triggers the requirement to bring the receptacles up to current code, including GFCI protection. This is not optional, and the ESA inspection at the end of your electrical work will verify it.

All bathroom electrical work requires an electrical permit and ESA inspection — this includes adding or relocating receptacles, installing a heated floor circuit, wiring a new exhaust fan, or upgrading vanity lighting. Never skip the permit for bathroom electrical work; unpermitted wiring is a liability issue and will surface during a home sale inspection.

If you are planning a bathroom renovation and want to confirm the exact outlet placement for your specific layout, a licensed GTA electrician can assess your space and ensure everything meets current code.
