How Much Does It Cost to Fix a Tripped Circuit Breaker in Ontario?

A tripped circuit breaker is one of the most common electrical issues homeowners encounter. In many cases it is a simple fix — but when a breaker keeps tripping, will not reset, or has failed, the underlying cause needs to be diagnosed by a licensed electrician. Here is what it costs to have a tripped or faulty breaker addressed in Ontario.

Tripped Circuit Breaker Repair Cost in Ontario

Having a tripped or faulty circuit breaker diagnosed and repaired by a licensed electrical contractor in Ontario starts at $200. This covers the service call, diagnosis of the cause, and the repair — whether that involves resetting the breaker, replacing a failed breaker, or addressing an overloaded or faulty circuit.

Why Does a Circuit Breaker Trip?

A circuit breaker trips as a safety mechanism — it detects a problem on the circuit and cuts power to prevent damage or fire. The three most common causes are:

• Overloaded circuit — too many appliances or devices drawing power simultaneously on a single circuit. The breaker trips when the total current exceeds its rating.
• Short circuit — a hot wire comes into contact with a neutral wire or ground, causing a sudden large current surge. This triggers an immediate trip.
• Ground fault — electricity follows an unintended path to ground, such as through moisture or a damaged wire. This is particularly dangerous and is the reason GFCI protection is required in wet areas.

When Should You Call a Licensed Electrician?

You can reset a tripped breaker yourself by switching it fully to the off position and then back to on. However, call a licensed electrician when:

• The breaker trips again immediately after resetting
• The breaker feels hot to the touch or you smell burning near the panel
• The breaker will not hold in the on position at all
• Multiple breakers trip at the same time
• The breaker has been tripping repeatedly over weeks or months
• You see or smell burning from an outlet, switch, or fixture on the circuit

Repeated tripping indicates an underlying electrical problem — overloaded wiring, a faulty appliance, deteriorated insulation, or a failing breaker — that needs diagnosis and correction. Repeatedly resetting a breaker without fixing the cause is a fire risk.

Does Breaker Replacement Require an ESA Permit in Ontario?

Replacing a single breaker on an existing circuit as a like-for-like repair typically does not require an ESA permit. However, if the work involves adding circuits, modifying the panel, or addressing wiring faults outside the panel, a permit may be required. Your licensed electrician will advise after diagnosis.

Under the Ontario Electrical Safety Code, all work inside an electrical panel must be performed by a licensed electrical contractor or master electrician. This applies to breaker replacement regardless of panel complexity.
