Do I need an electrician to install a whole-home WiFi mesh system?

You do not need an electrician for a basic plug-and-play WiFi mesh system, but you absolutely should hire one if you want ceiling-mounted access points with PoE wiring — which is the setup that delivers truly reliable whole-home coverage. The consumer mesh kits from brands like Google Nest, Eero, and TP-Link are designed for homeowner installation and simply plug into existing outlets, but they have real limitations in larger GTA homes.

Consumer mesh systems work by placing satellite units around your home, each plugged into a standard outlet. They communicate wirelessly with each other and your router. For a typical 1,500 to 2,000 square foot GTA bungalow or two-storey, a three-pack mesh system ($250 to $500) usually provides adequate coverage. You place one unit near your internet connection, one on the upper floor, and one in the basement — no electrical work needed. However, in larger homes, homes with plaster-and-lathe walls (common in older Toronto neighbourhoods), or multi-storey homes with concrete between floors, wireless mesh performance degrades significantly.

The professional alternative is ceiling-mounted access points connected via Cat6 ethernet cable and powered by PoE (Power over Ethernet). This eliminates the wireless backhaul bottleneck that slows down consumer mesh systems. Each access point is mounted on the ceiling in a central hallway location on each floor, connected by a single Cat6 cable back to a PoE switch in your utility area. Enterprise-grade access points from Ubiquiti or TP-Link Omada cost $100 to $200 each, and a PoE switch runs $100 to $300. The real cost is the cabling — running Cat6 through finished walls and ceilings in an existing GTA home typically costs $200 to $400 per drop, including the cable, wall plates, and labour.

This is where a licensed electrician adds value. Running cables through walls, drilling through fire stops between floors, and mounting equipment on ceilings requires someone who understands building structure and knows how to avoid existing electrical wiring, plumbing, and HVAC ducts hidden inside walls. In older Toronto homes, you may encounter knob-and-tube wiring, asbestos insulation, or unexpected framing configurations. An experienced electrician navigates all of this safely. The low-voltage cabling itself does not require an ESA permit in most cases, but if any electrical circuits are added or modified (such as a dedicated circuit for your networking equipment), a permit is required.
