Permit requirements protect your safety and home value.
How much does a 200 amp electrical panel upgrade cost in Sarnia?

What is aluminum wiring and is it dangerous?
Aluminum branch circuit wiring installed in homes built between 1965–1973 is a fire hazard and should be remediated immediately. Aluminum expands differently than copper connectors, loosening over time and causing arcing, heat, and potential fires. Homes in Sarnia built during this era commonly have aluminum wiring. Remediation options include pigtailing (wrapping copper wire around connections) or full rewire using copper per the Canadian Electrical Code. A licensed electrician in Sarnia can inspect your panel and recommend the safest solution.
How do I know if my electrical panel needs to be replaced?
Replace your electrical panel in Sarnia immediately if you notice frequently tripped breakers, burning smells near the panel, flickering lights, or a panel over 30–40 years old. Defective brands like Zinsco, Federal Pacific, and Pushmatic have high failure rates and must be replaced. Panels rated under 200 amps cannot support modern electrical demands or EV chargers. A licensed electrician inspection costs CAD $150–CAD $300 and identifies safety issues. ProvenQuote-verified electricians in Sarnia provide free replacement quotes.
