Are outdoor electrical outlets required to be weatherproof in New Brunswick and what type do I need?

Yes, all outdoor electrical outlets in New Brunswick must be weatherproof — and the Canadian Electrical Code specifies two different levels of protection depending on whether the outlet is in use or not. Getting this wrong isn't just a code violation, it's an electrocution and fire hazard, particularly in New Brunswick's rain, snow, and ice conditions.

The two types of weatherproof covers you need to know about:

"While-in-use" covers (also called bubble covers or extra-duty covers) are required for any outdoor outlet where something may be plugged in for extended periods — Christmas lights, block heaters, landscape lighting, or pool pumps. These covers have a raised dome or box shape that allows a cord to exit while the cover remains closed. The CEC requires while-in-use covers on all outdoor outlets that are readily accessible, which means virtually every outdoor outlet on your New Brunswick home needs this type.

Standard weatherproof covers with spring-loaded flaps only protect the outlet when nothing is plugged in. These are no longer sufficient for most residential outdoor locations under current code but were the standard on older homes. If your home has the flat, flip-up style covers on outdoor outlets, they should be upgraded to while-in-use covers.

All outdoor outlets must also be GFCI protected. This is a separate requirement from the weatherproof cover. GFCI protection can be provided by a GFCI outlet, a GFCI breaker in the panel, or by being downstream of a GFCI outlet. In New Brunswick's wet Maritime climate, this protection is critical — salt fog in coastal areas like Saint John and Shediac, driving rain, and snowmelt all increase the risk of ground faults.

The outlet box itself matters. Outdoor electrical boxes must be rated for wet locations (marked "WR" or "weather resistant"). The box must be mounted with the opening facing down or horizontally — never facing up where water can pool inside. All connections must use weatherproof wire nuts or approved outdoor connectors.

New Brunswick-specific considerations. Maritime weather is particularly harsh on outdoor electrical. Salt air corrodes contacts and connections, freeze-thaw cycles can crack plastic covers, and ice buildup can force covers open. Use stainless steel screws instead of standard zinc-plated screws on cover plates. Choose covers rated for extreme weather (look for extra-duty or industrial ratings). And inspect your outdoor outlets each spring after the winter freeze-thaw cycle — cracked covers and corroded outlets should be replaced immediately.

The cost to upgrade outdoor outlets to current code with while-in-use covers and GFCI protection is typically $100 to $200 per outlet if the wiring is already in place, or $300 to $600 per outlet for new installations including running wire from the panel. Most New Brunswick homes have 2 to 4 outdoor outlets, so a full upgrade runs $400 to $1,200.

If you're adding new outdoor outlets or upgrading existing ones, a TSANB permit is required for new circuits. Replacing just the cover on an existing outlet doesn't require a permit, but upgrading from a standard outlet to a GFCI outlet on an existing circuit is a grey area — consult your electrician about whether a permit is needed for your specific situation.
