Can I run my own electrical wire?

In Ontario, homeowners are legally prohibited from running most electrical wiring themselves. Only ESA-licensed electrical contractors can install new circuits, and virtually all wiring work requires permits and professional installation.

What the Law Says

The Ontario Electrical Safety Code and ESA regulations are clear: homeowners can only perform very limited electrical work. You can replace outlets, switches, and light fixtures on existing circuits (with the power shut off), but that's essentially it. Running new wire, adding circuits, or modifying electrical systems must be done by licensed electricians.

This isn't just a bureaucratic rule - it's about preventing house fires, electrocution, and ensuring your insurance coverage remains valid. DIY electrical work that requires a permit can void your home insurance if it causes damage or injury. Insurance companies routinely deny claims for electrical fires caused by unpermitted work.

ESA Permit Requirements

Running electrical wire almost always requires an ESA permit in Ontario. Whether you're adding a new outlet, installing a dedicated circuit for an appliance, or running wire to a garage or shed, you'll need:

• A licensed electrician to pull the permit


• Work completed to Ontario Electrical Safety Code standards


• ESA inspection within 3-5 business days


• Certificate of Inspection before the work is considered legal

Electrical mistakes aren't just code violations - they're deadly. Incorrect wire sizing can cause fires, improper connections create arc faults, and inadequate grounding leads to electrocution hazards. Professional electricians spend years learning proper techniques, load calculations, and safety procedures that aren't obvious to homeowners.

Even seemingly simple tasks like running wire through walls involve understanding fire-stopping requirements, proper stapling intervals, and junction box fill calculations. Get it wrong, and you could face expensive repairs when the ESA inspector fails your work.

What You Should Do

For any electrical project involving new wiring, contact ESA-licensed electricians for quotes. In Ottawa, typical costs for new circuits range from $300-600 depending on complexity and distance. While it might seem expensive compared to DIY, professional installation includes permits, inspections, and the peace of mind that your family's safety isn't at risk.

Remember: electrical work can kill. The few hundred dollars you might save doing it yourself isn't worth the risk to your family or your home.
