What is the cost to add a new circuit in my home?

Adding a new circuit in Ottawa typically costs between $300-$800, depending on the circuit type, distance from the panel, and complexity of the installation. This price includes the ESA permit, materials, labor, and inspection.

The cost varies significantly based on what you're powering and where it's located. A simple 15-amp circuit for general outlets might cost $300-$500, while a dedicated 20-amp circuit for a kitchen appliance or 240V circuit for a dryer could run $500-$800. The biggest factors affecting price are the distance from your electrical panel (longer wire runs cost more), accessibility of the route (finished vs. unfinished spaces), and whether walls need to be opened and patched.

Circuit Type Breakdown:

• 15-amp general circuit: $300-$500 (bedrooms, living areas)


• 20-amp kitchen/bathroom circuit: $400-$600


• 240V appliance circuit (dryer, electric range): $500-$800


• Outdoor circuit with GFCI: $400-$700


• Garage/workshop circuit: $350-$600

In Ontario, adding any new circuit requires an ESA permit, which your licensed electrician will obtain before starting work. The permit fee (around $75-$100) is typically included in the quoted price. After installation, ESA will inspect the work within 3-5 business days to ensure it meets Ontario Electrical Safety Code requirements.

Important considerations for Ottawa homes: Many older homes have panels that are already at capacity. If your panel can't accommodate another breaker, you might need a subpanel installation ($800-$1,500) or a full panel upgrade ($2,000-$3,500). A qualified electrician can assess your panel's available capacity during a free consultation.

The installation process involves running new wire from your panel to the desired location, installing outlets or hardwired connections, and updating your panel with the appropriate breaker. In finished spaces, this may require some drywall patching, which most electrical contractors can handle or coordinate.

Safety note: Adding circuits requires working inside your electrical panel with live wires - this is dangerous work that must be done by an ESA-licensed electrician. DIY electrical work beyond simple outlet replacements is illegal in Ontario and will void your home insurance if it causes damage.
