Licensed Electrician and Electrical Contractor in Markham

Search the business on ESA's Contractor Locator Tool by name, licence number, phone number or location. A Valid status means the licence is active and Expired means it has lapsed. If the company does not show up at all, it does not hold a licence, and ESA's rules say anyone you pay for electrical work in your home must.

Ask for the ESA Certificate of Acceptance once the inspection passes. ESA describes it as an important record for insurance, for resale and for your own peace of mind, and it suggests asking whichever contractor filed the notification for a copy. Keep it with the house documents along with any Alectra or City paperwork tied to the job.

Ordinary wiring is filed with ESA rather than the City. A City building permit enters the picture when the project itself needs one, for example a secondary suite, which Markham requires to be permitted before work begins and registered afterward. Your contractor's ESA notification still covers the electrical part of that project. To book a quote, call 905-999-5048.

If the property sits inside one of Markham's heritage conservation districts, very likely yes. The City says owners and tenants in those districts need a heritage permit for exterior changes, and it names non-structural items such as exterior lighting, painting and replacement windows or doors among them. Staff can approve a Minor or Major Heritage Permit when the work follows the district plan. Check the City's district maps first, then plan the fixture style and placement before the electrical rough-in, since the ESA notification covers the wiring but not the heritage approval.

Markham's homeowner guide for secondary suites says a building permit must be obtained before the suite is added, and that the electrical service to and within the house has to be sized to accommodate the extra unit. That makes a load calculation the first electrical step, because a second kitchen, laundry and heating can push an older service past its rating. The wiring itself is filed with ESA as its own notification. Once construction is finished, Markham requires every two-unit house to be registered, and the City inspects both units.

Most wiring jobs inside the house never touch the utility. Alectra becomes part of the project when the service changes: a larger service, a panel change that needs the power cut at the meter, or a generator connection. Its service request page explains that after an upgrade, Alectra will reconnect the existing service only once it has received ESA's connection authorization, so the inspection has to pass before the lights come back on. Your contractor normally submits the request and lines up the disconnect date with you.

Yes, in your own home and under conditions. ESA allows a homeowner to do electrical work in the house they own, but a notification has to be filed with ESA first and the work is inspected like any other. Friends, relatives and neighbours are not allowed to do it for you, and anyone you pay must be a Licensed Electrical Contractor. For service work, suites and new circuits, most owners hire a contractor because the contractor carries the notification and the inspection from start to finish.
