City of Toronto rules

Decking rules in Toronto.

Checked against the City of Toronto's own website. Lots differ, so we confirm the rules for your address at the quote visit.

  • Private trees

    A permit is required to remove or injure a private tree 30 cm or more in diameter (measured 1.4 m above ground). City street trees are protected at any size — this often decides where fence posts and deck footings can go.

  • Ravines & conservation

    Properties near ravines and valleys are regulated by the Toronto and Region Conservation Authority (TRCA) and the City's ravine bylaw — decks, walls and regrading there may need extra approval.

  • Deck permits

    Under Ontario's Building Code, a deck over 10 m² (about 108 sq ft) or attached to the house generally needs a building permit, and the City of Toronto may set its own triggers based on height above grade. We confirm with the building department and pull the permit when one's needed.
