Bathroom Fan Installation in Toronto & the GTA

A tired bathroom fan announces itself: it rattles, it barely pulls the mist off the mirror, and the paint on the ceiling starts peeling anyway. Weak bathroom ventilation is behind most of the mould calls we get, because a fan that can't clear the room in ten minutes leaves moisture soaking into grout, caulk and drywall every single day.

A proper bath fan swap is more than pulling one unit out and pushing another in. The new fan has to match or adapt to the existing housing opening, connect to the duct with a sealed joint, and actually vent outside — a surprising number of GTA fans blow into the attic or a soffit cavity, which quietly rots roof sheathing. Sizing matters too: the fan's airflow rating should suit the room's size, and a larger or quieter model sometimes needs the ceiling opening enlarged and the drywall made good afterwards. The wiring side has a hard rule in Ontario, covered in the FAQs below.

For a free quote, send a photo of the existing fan grille, one of the room, and the model you're considering if you've chosen one. If you can safely photograph where the duct goes in the attic, even better — it tells us whether the venting needs correcting at the same time.

What this covers

  • Removal of the old exhaust fan and housing
  • Exhaust fan replacement matched to the room's size
  • Enlarging or reframing the ceiling opening for a different-sized unit
  • Sealed duct connection to the existing vent line
  • Correcting ducts that dump into the attic, where accessible
  • Drywall patching and touch-up around the new housing
  • Grille and cover fitting, plus humidity-sensing models on request
  • Testing airflow at the grille after installation
  • Coordination with a Licensed Electrical Contractor when new wiring is required

What affects the price

  • Housing size difference — a same-size swap is quick; a bigger or differently shaped housing means cutting and patching ceiling drywall
  • Duct condition and route — crushed, disconnected or attic-dumping ducts need correcting or the new fan performs no better than the old one
  • Attic access — fans reachable from above are simpler than ones that must be done entirely from the room below
  • Wiring changes — reusing the existing connection is minor; any new hardwired circuit work is completed by a Licensed Electrical Contractor and affects scope
  • Fan features — humidity sensors, timers and integrated lights add wiring complexity beyond a basic single-switch fan
  • Ceiling height and finish — high ceilings and textured finishes make the patching and access slower

Common questions

Who does the electrical part of a bathroom fan installation in Ontario?
Hardwired electrical connections must be completed by a Licensed Electrical Contractor registered with the ESA — we don't do that work ourselves and won't pretend otherwise. Where a replacement fan reconnects to the existing wiring like-for-like, that's minor work; where a new circuit, switch or hardwired connection is needed, we arrange the licensed portion and handle the mounting, ducting and finishing around it. You'll know which situation you have before the job starts.
My fan runs but the mirror still fogs for ages. Do I need a bigger fan?
Sometimes, but check the duct first. A fan rated well for the room that's pushing into a crushed, kinked or disconnected duct moves almost no air. We test at the grille — a sheet of toilet paper should hold itself flat against a healthy fan — and inspect the duct run where we can. Often the fix is a duct correction plus a properly sized unit, not just the biggest fan on the shelf.
Can you make the new fan quieter than the old one?
Almost certainly. Older builder-grade fans run loud; modern units are dramatically quieter at the same or better airflow. The quiet models are often slightly larger, so the honest trade-off is that the ceiling opening may need enlarging and patching. Tell us if silence is the priority and we'll factor that into the quote.
Where should the bathroom fan vent to?
Outside — through the roof or a wall, with an insulated duct in cold spaces and a proper exterior hood. Venting into the attic or a soffit is common in older GTA houses and it pushes litres of moisture into the roof structure every week, which shows up later as frost, mould and stained ceilings. If we find that arrangement during a bath fan swap, we'll quote putting it right.
How do I know what size fan the room needs?
Airflow ratings are based on room volume — a typical GTA bathroom needs a modest rating, while large ensuites, high ceilings or separate shower rooms need more. Long duct runs also steal capacity, so a fan on a twisting route should be rated above the room's minimum. Send your room dimensions with the photos and we'll recommend a sensible size rather than guessing at the store.
