Planning a Bathroom Renovation
A bathroom renovation starts with the existing wet areas, ventilation, layout and the interfaces between waterproofing and finishes.
When Does Bathroom Fan Installation Require a Licensed Electrical Contractor?
Direct answer
If you hire someone to do the electrical part of a bathroom fan installation in Ontario, that person must be an ESA Licensed Electrical Contractor. New wiring or a circuit clearly belongs in that electrical scope; reconnecting a replacement fan to an existing connection must also be described to the LEC or ESA rather than assumed exempt. The physical housing, grille and duct work can be scoped separately. ESA says almost all electrical work needs a notification, filed by the person doing it before work starts; a building permit does not replace it.

| Item | What to know |
|---|---|
| Housing or duct work | Describe mechanical work and any building-approval question separately. |
| Existing connection | Ask the LEC or ESA how the actual replacement and notification are handled. |
| New wiring or circuit | Use an LEC for hired electrical work and plan ESA notification. |
Split the work into parts
List the fan housing, grille, duct route, exterior termination, switch, wiring and any circuit change. A fan quote that says only ‘replace unit’ can hide electrical and ventilation details. Check whether the new unit is compatible with the opening and duct and whether an opening or other building work needs City review.
Apply ESA rules to the electrical part
ESA says a homeowner may do their own electrical work under its DIY rules and file a notification. If someone is hired for electrical work in the home, an LEC must perform it; a general contractor should arrange that LEC. Almost all electrical work requires an ESA notification before work starts. ESA’s general guidance does not establish a blanket exemption for swapping a fan on an existing connection, so confirm the actual scope with the LEC or ESA.
Choose the scope after inspection
A grille or non-electrical component problem may need a small mechanical repair. Poor duct routing, moisture damage or an undersized opening can widen the work. New cable, switch or circuit changes require the electrical trade. Keep patching and painting in the scope if ceiling access is needed.
Renovation1 approach
We would document the fan, opening and accessible duct conditions, identify any ceiling finish work, and refer hired electrical connections or wiring to an LEC. The estimate would identify the electrical contractor responsibility before any electrical work starts.
What Renovation1 does in practice
Send a photo of the fan and grille, the model label, accessible duct route and switch location. Say whether the requested work is a like-for-like unit change, new location or new circuit; ESA or the LEC decides the notification handling.
