What's the code for electrical outlets near water?

Electrical outlets near water in bathrooms are governed by both the Ontario Electrical Safety Code (ESC) and enforced locally through the Electrical Safety Authority (ESA) in Ontario — not the Ontario Building Code directly.

The core requirement is that all bathroom receptacles must be GFCI-protected (Ground Fault Circuit Interrupter). A GFCI outlet cuts power in milliseconds if it detects a ground fault, preventing electrocution near water sources.

Key requirements you should know:

The ESA requires GFCI protection for any receptacle installed in a bathroom. There are also minimum distance rules — outlets must be installed a certain distance from water sources like sinks, tubs, and showers, though the exact measurements can vary based on the specific installation and inspector interpretation. Outlets cannot be installed inside a shower or tub enclosure at all.

Placement matters practically too. Most bathroom outlets end up near the vanity for hair dryers, electric shavers, and similar appliances. A licensed electrician will know the required setback distances and height requirements for your specific layout.

In Ottawa specifically, all electrical work in a bathroom renovation requires an ESA permit and inspection — this is separate from any building permit. This applies even if you're just adding or relocating an outlet. Unpermitted electrical work can void your home insurance and cause serious problems at resale.

For exact current code distances and specifications, always confirm with your licensed electrician or the Electrical Safety Authority (ESA Ontario) directly, as requirements can be updated.
