A small snap or a single blue flicker the moment you plug something in is normal arcing and usually harmless. What is not normal is a spray of sparks, a crackling or sizzling sound that keeps going, or a plug that feels loose and hot in the socket. Any of those means the contacts inside the receptacle are worn or the connection behind it is failing, and it can heat up under load.

A burning or fishy smell near an outlet, a switch plate that is warm to the touch, or brown scorch marks and discoloured plastic are the clearest warnings of all. Switch the circuit off at the breaker, leave it off, and put a piece of tape over the outlet so nobody uses it by habit. Do not wiggle the plug to test it, and do not open the device yourself unless you are qualified — the panel and the wiring behind it stay live in places you cannot see.
A breaker that trips once when a kettle, a space heater and a microwave run at the same time is doing its job. A breaker that trips repeatedly on the same circuit, or a light that dims every time the fridge starts, is telling you the circuit is overloaded or a connection is loose. Repeated tripping is also how a tired breaker eventually fails to trip at all, which is the outcome worth avoiding.
Buzzing from a dimmer is often just an older dimmer fighting with LED bulbs, and swapping the dimmer for an LED-compatible one usually settles it. In homes from the 1960s to the 1980s, aluminium branch wiring and outlets wired through the small push-in holes at the back — instead of the screws — are the two known weak points. Neither is an emergency on its own, but both are worth a licensed electrician's opinion, especially before you add a heavy appliance.
Photograph the outlet or switch straight on with the plate in place, then the scorch mark close up with a coin beside it for scale, then the breaker panel with the tripped breaker visible and its label readable. Note the date and what was running when it happened. Those four photos answer most of the questions an electrician or an adjuster would ask, and they cost you two minutes.
Published Québec pricing for 2026, built on rates recommended by the Corporation des maîtres électriciens du Québec, puts a receptacle or a light fixture at about C$150 to C$350 installed, a new dedicated circuit at roughly C$1,000 once the connection is included, and a panel replacement at about C$2,000 to C$4,000. Ontario quotes tend to run a little lower on simple jobs and similar or higher on panel work. Getting a photo-based severity read before you call means you can ask the right question, budget for the right job, and avoid paying for work you did not need.
Two things explain why no single number survives across the country. First, labour: federal wage data for electricians shows a median of about C$35.00 an hour in Canada, C$34.00 in Ontario and C$41.30 in Québec, and regional figures move again — about C$34.86 in Toronto against C$43.00 in the Montérégie. What you are billed is higher than any wage, because it also covers insurance, the vehicle, permits and the contractor's overhead. Second, the rules differ by province: in Ontario almost all electrical work must be reported to the Electrical Safety Authority, and anyone you hire must be a Licensed Electrical Contractor, who can also issue the certificate your insurer will want. In Québec the law requires a master electrician for virtually everything beyond changing a bulb, a cover plate or a fuse. Expect a permit or inspection line on your quote, and do not compare it across provincial borders.
