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.

Follow-up Questions
If new circuit is 30 feet distance to service panel, how much would it cost ?
For a new circuit with a 30-foot run to your panel, you're looking at a relatively straightforward installation - expect to pay in the $350-$550 range for a standard 15 or 20-amp circuit.
Thirty feet is considered a short-to-moderate run, which keeps both material and labor costs on the lower end. At that distance, you're looking at roughly 60-70 feet of wire total (accounting for the return path and some slack), which is well within the range where costs stay manageable. The wire itself for a 30-foot run might cost $30-$60 in materials depending on gauge - 14 AWG for a 15-amp circuit or 12 AWG for a 20-amp circuit.
The bigger cost factors at this distance aren't the wire itself - it's the accessibility of the route. If the run travels through an unfinished basement or open ceiling joists, an electrician can complete the job in 2-3 hours. If the wire needs to travel through finished walls with drywall, expect the job to take longer and potentially require some patching, pushing the cost toward the higher end of that range or slightly above.
Rough breakdown for your 30-foot circuit:
- Labor (2-4 hours): $200-$350
- Materials (wire, breaker, outlet/box): $50-$100
- ESA permit and inspection: $100-$150
- Total: $350-$600
For a 240V circuit at 30 feet (dryer, EV charger, etc.), budget $500-$750 since the wire is heavier gauge and the breaker costs more. A 30-amp or 40-amp double-pole breaker alone runs $30-$60 in materials.
One thing worth confirming before booking: make sure your panel has an open breaker slot available. If your panel is full, even a simple 30-foot run becomes a bigger project requiring a tandem breaker, subpanel, or full upgrade. An electrician can assess this quickly during a site visit.
