You plug in a lamp and nothing happens. Every other outlet in the room works. The lamp works elsewhere. Before you call an electrician, there are three safe checks you can do yourself to fix a dead outlet, and about half the time one of them restores power without any tools at all.
Step one, walk the whole house and look for a tripped GFCI outlet with a popped-out reset button — usually in a bathroom, kitchen, garage, or exterior wall. One tripped GFCI can kill a chain of outlets in rooms nowhere near the trip. Press the reset button firmly until you hear a click and check if your dead outlet comes back. Step two, check your electrical panel for a tripped breaker — a tripped breaker often sits in the middle, not fully at “off,” and you have to push it fully off then back on to reset. Step three, check any wall switch in the room; some outlets are switch-controlled from the doorway.
If the outlet is still dead after those three checks, do not open it yourself. In Ontario, opening outlets and testing wires is licensed work — and touching the wrong terminal without a proper tester can cause serious injury. The likely culprits from here are a failed back-stab connection at an upstream outlet, a loose wire nut inside a junction box hidden in the wall, or a burned-out receptacle. All are common and cheap for a licensed pro to fix, and you have already saved us time by narrowing it down. See our related guide on what to do when half your outlets stop working suddenly for the panel-side version of this problem.
Four causes account for the majority of our GTA service calls. Age — back-stab outlets installed 20+ years ago simply wear out. Overload — a space heater or portable AC drawing 12A continuously on a $2 builder-grade outlet cooks the internal contacts. Loose wire nuts upstream — someone did a DIY connection years ago and the neutral has finally worked itself loose. And GFCI aging — the GFCI mechanism itself has a limited lifespan (roughly 10 to 15 years) and can silently stop protecting downstream outlets. Any bathroom or kitchen with an original GFCI from the 2000s is due for replacement.
One more scenario worth mentioning: rodent damage. In older Toronto homes with unfinished basements or accessible attics, mice and squirrels occasionally chew through cable jackets, breaking the neutral without shorting the hot. The outlet goes dead, no breaker trips, and there is no visible sign until an electrician traces the wiring back to the damage.
When you replace a dead outlet, always upgrade to a tamper-resistant, spec-grade receptacle with side-wire (screw) terminals, not the cheap push-in “back-stab” version. It costs about $4 more and lasts three times as long. If it is a kitchen or bathroom, a fresh GFCI outlet installation is the code-compliant fix.
