Permits in Ontario
Building permits are issued by your municipality under the Ontario Building Code. Requirements and fees differ from one city to the next.
Commonly triggered by this project
- Deck construction. Decks above a certain height or area normally require a permit, and footings may need inspection.
Hiring in Ontario
Ontario does not license general contractors or renovators. Anyone can advertise renovation work, so the paperwork you check matters more than any claimed credential.
Trades that must be certified
- Electrical: Only a licensed electrical contractor may do electrical work for hire. The licence number starts with ECRA/ESA and is searchable.
- Gas and propane: Gas lines, furnaces, fireplaces, and water heaters must be handled by a TSSA-certified gas technician.
- Plumbing: Plumbing is a compulsory trade in Ontario. Ask for a Certificate of Qualification from Skilled Trades Ontario.
- New homes and substantial additions: Building or selling a new home in Ontario requires an HCRA licence. Ordinary renovations do not.

Questions homeowners ask
- Does a deck need a building permit?
- Many municipalities require a permit once a deck exceeds a set height or area, or when it is attached to the house. Because thresholds differ by municipality, treat every deck as a permit check.
- Is composite decking worth the extra cost?
- Composite raises material cost but lowers annual maintenance. Compare total cost over the years you expect to keep the home, not just the install price.
