Dimmer & Switch Installation in Toronto & the GTA

Switches are the part of a house everyone touches daily and nobody upgrades. Paint-crusted toggles from 1985, a dimmer installation that buzzes and flickers with the LED bulbs it was never designed for, three-way switch setups where nobody remembers which switch does what — and a drawer full of smart switches bought on sale, waiting. Swapping switches is genuinely small work per device, which is exactly why it's worth doing a whole floor at once.

The work itself is precise rather than difficult, and the details are where amateur jobs go wrong. LED loads need LED-compatible dimmers matched to the bulb type, or you get flicker and hum forever. A smart switch installation lives or dies on whether the box has a neutral conductor — plenty of older Toronto homes don't have one at the switch, which changes what hardware can go in. Three-way circuits have travellers that must be identified, not guessed. And under Ontario law, electrical work for hire is performed by a Licensed Electrical Contractor registered with the ESA — so the device wiring on our jobs is done by an LEC, while we coordinate everything, handle app setup on smart switches, replace the plates, and leave the walls clean.

For a free quote, walk your home and list every switch you want changed — location, what it controls, and what you want there (dimmer, smart switch, timer, or just a clean new switch). Photograph a couple of the existing switches with the plate on. If you already own the new devices, list the models; compatibility questions are far cheaper to answer before the visit than during it.

• Single-pole light switch replacement
• LED-compatible dimmer installation, matched to your bulbs
• Smart switch installation with app and voice-assistant setup
• Three-way switch and dimmer configurations for hallways and stairs
• Timer switches for bathroom fans and exterior lights
• Fan speed control installation
• Neutral-wire assessment for smart switch compatibility
• Multi-gang layouts kept tidy and labelled
• New cover plates throughout
• Device wiring completed by a Licensed Electrical Contractor

• Neutral wire availability — many older GTA switch boxes lack a neutral, which limits smart switch options or requires no-neutral models
• Three-way and four-way circuits — multi-location switching takes correct traveller identification and compatible multi-location dimmers
• Box space — smart switches are deep, and shallow or crowded boxes make the fit tight or impossible without changes
• Bulb compatibility — dimmer and LED pairings must match, or the result is flicker, and sometimes the honest fix is better bulbs
• Switch count — per-switch effort falls sharply as the list grows, so whole-floor refreshes are the best value
• Wiring era — aluminum wiring or very old cloth-insulated conductors need the Licensed Electrical Contractor's specific attention at every device
