How do I know if my house wiring is up to code?

Your house wiring may not be up to current Ontario Electrical Safety Code standards, especially if it's over 20 years old or has never been updated. Most homes built before 2000 will have some code deficiencies by today's standards, though they may have been compliant when originally installed.

The most reliable way to determine if your wiring meets current OESC requirements is to have a licensed electrician perform a comprehensive electrical inspection. They'll check your panel, circuits, outlets, and safety devices against current ESA standards. This inspection typically costs $200-400 in Ottawa and provides a detailed report of any code violations or safety concerns.

Common code deficiencies in older Ottawa homes include missing GFCI protection within 1.5 meters of sinks, lack of AFCI protection in bedrooms, insufficient grounding, outdated panels (especially Federal Pacific or Zinsco brands), and inadequate circuit capacity for modern electrical loads. Homes with knob and tube wiring or aluminum branch circuits will definitely need updates to meet current safety standards.

Key areas ESA inspectors focus on include proper GFCI protection in bathrooms, kitchens, garages, and outdoor areas, adequate panel clearances (1 meter in front, specific side clearances), proper grounding throughout the home, and tamper-resistant outlets in newer installations. If you're planning renovations, any new work must meet current code regardless of your home's age.

Signs your wiring needs attention include frequently tripping breakers, flickering lights, warm outlets or switch plates, burning smells, or any sparking. Federal Pacific or Zinsco panels should be replaced immediately due to fire risks, and knob and tube wiring with insulation creates serious fire hazards.

Insurance companies increasingly require electrical inspections for homes over 40 years old, and some won't insure homes with knob and tube or aluminum wiring without upgrades. If you're buying or selling a home, an electrical inspection can prevent costly surprises and ensure safety compliance.

For your specific situation, contact a licensed electrician from Electrical Ottawa for a thorough assessment. They can identify code violations, prioritize safety concerns, and provide estimates for bringing your electrical system up to current OESC standards. Remember, electrical work in Ontario requires ESA permits and inspections - this isn't a DIY assessment.
