Bypassing a light switch to keep power always on — usually because a homeowner is installing a smart bulb, a smoke alarm, or a hardwired appliance that should never be turned off — sounds simple, but it needs to be done to Ontario Electrical Safety Code or it becomes a real fire and shock risk. This guide walks GTA homeowners through how to bypass a light switch safely, when a bypass is the right choice, and when a blank cover plate or a re-fed circuit is a better long-term answer.
Direct answer: bypass a switch only when the load downstream should never be interrupted — smart bulbs that need constant power to accept commands, hardwired smoke and CO alarms tied to a shared line, exhaust fans on a timer, or a wall receptacle that used to be switch-controlled. Every other case is better served by leaving the switch in place.
In every case, ask first whether a scene controller or wireless switch would be a better answer. Our post on adding a switch without new wire covers the wireless alternatives that keep the switch functional as a control point.
Direct answer: three shortcuts we see and always correct — (1) wrapping the switch toggle in tape so it cannot be flipped, (2) removing the switch and leaving the conductors bare in the box under a cover plate, and (3) removing the box entirely and hiding the splice behind drywall. All three violate the Ontario Electrical Safety Code.
Taping the switch does not make the bypass compliant — anyone can peel the tape off, and the switch is still an electrical device the code expects to work reliably. Leaving bare conductors under a cover plate creates a shock risk any time someone opens the plate. Burying a splice inside a wall is explicitly forbidden by OESC Section 12 — all junctions must remain accessible. The Electrical Safety Authority lists buried and inaccessible splices as one of the most common serious writeups on renovation inspections.
Direct answer: if the reason for the bypass is a smart bulb, install a smart-bulb-friendly control instead of removing the switch. Options include a Lutron Aurora that clips over the existing toggle and locks it in the on position while adding a functional dimmer, or a Zigbee or Wi-Fi wall remote next to a permanently-jumped switch inside the box.
The Aurora is Canadian-retail available and installs in about ten minutes. It maintains a functional-looking switch on the wall while sending signals to your smart bulb, so nobody accidentally kills power to the bulb by flipping the toggle. Our related post on smart switch installation covers the drop-in options.
Direct answer: call an electrician if the switch box contains more than two conductors coming from more than one cable, if the wiring is aluminum, if any conductor shows heat discolouration, or if you cannot identify which conductor is line versus load. A bypass in any of those conditions is beyond homeowner-permitted work under the Ontario Electrical Safety Code.
Multi-cable boxes usually mean the switch controlled more than one fixture, or was a mid-circuit passthrough for downstream receptacles. Splicing the wrong pair together can energize a downstream receptacle even when the breaker is off elsewhere. Get a professional to trace the circuit before you commit.
In our experience answering “how do I keep this switch always on” calls across the GTA, the customer almost always wanted a switched receptacle to become unswitched. The right long-term fix is not to bypass the wall switch, but to change the receptacle so both halves are unswitched and remove the tab break between the two halves inside the receptacle. That leaves the wall switch alive for future use, keeps everything code-compliant, and takes about fifteen minutes. Homeowners who bypass the switch instead often lose the ability to add a lamp or fan on that wall in the future without opening drywall.
