What is the best way to run internet and cable wiring during a GTA basement renovation?

The best time to run data and entertainment cabling in your basement is during the rough-in phase, after framing is complete but before drywall goes up — running cables through open stud walls costs a fraction of what it would cost to fish wires through finished walls later. Plan your network infrastructure with the same care you give to electrical and plumbing, because in 2025 a finished basement without proper data wiring is like a kitchen without adequate outlets.

Run Cat6 or Cat6A ethernet cable to every location where you might want a wired connection — this includes your home theatre setup, gaming area, home office or desk location, smart TV locations, and at least one or two spare locations for future flexibility. Cat6 cable supports 10-gigabit ethernet at short distances and is future-proof for residential use. A 1,000-foot box of Cat6 cable costs $100-$200 at electrical supply houses, and pulling cables through open stud walls is fast work. Each cable run terminates at a keystone jack in a wall plate at the room end, and all cables home-run back to a central location where your network switch and router will live. Avoid daisy-chaining or splitting cables — each device gets its own dedicated cable run back to the central point.

Set up a small network closet or structured wiring panel in your mechanical room or a utility area. A wall-mounted network rack or structured wiring enclosure ($50-$200 for the panel) gives you a clean, organized location for your router, network switch, patch panel, and cable modem. Position this panel near where your internet service enters the home and near an electrical outlet. A small 8-port or 16-port gigabit network switch ($30-$100) connects all your ethernet runs. This centralized approach means every device in the basement has a dedicated, high-speed wired connection, and you can add a wireless access point connected to the network switch to provide strong WiFi coverage throughout the basement.

Speaking of WiFi, basement WiFi is notoriously poor when relying on a router located on the main floor or upper level. The floor structure, ductwork, and concrete create significant signal attenuation. Run an ethernet cable to a central basement ceiling location and install a ceiling-mounted wireless access point (Ubiquiti, TP-Link Omada, or similar at $100-$200). This provides far better WiFi coverage than any mesh system or repeater trying to penetrate through the floor from above.

For television, run RG6 coaxial cable to each TV location if you use cable television, though many GTA homeowners are moving to streaming-only setups that only need ethernet or strong WiFi. If you are building a home theatre, run RG6 to the projector or TV location and to the media cabinet where your cable box or streaming devices will live. Also run HDMI cable in conduit (not bare HDMI cable, which cannot be easily replaced) between the projector location and the media cabinet if the two are separated by more than a few feet. A 1.5-inch or 2-inch conduit between these points lets you pull new HDMI cables or fibre-optic HDMI cables as standards evolve.

Run empty conduit to locations where future needs are uncertain. A 1-inch or 1.5-inch flexible conduit (smurf tube) costs very little during rough-in but saves hundreds of dollars if you ever need to pull a new cable to a location after the walls are finished. Run conduit between the network closet and each wall where you might add technology later — smart home controllers, security cameras, additional displays, or speakers.

All low-voltage wiring should be kept separated from electrical wiring by at least 12 inches where running parallel, and should cross electrical wires at 90-degree angles when they must intersect. While low-voltage data cabling does not require an ESA permit (it carries no dangerous voltage), coordinating with your electrical contractor ensures clean, organized cable management and avoids interference between power and data lines. Budget $500-$2,000 for a comprehensive basement data wiring setup during renovation, compared to $2,000-$5,000 or more to retrofit cabling into finished walls later.
