Do retaining walls in Islington-City Centre West need a building permit?

In Ontario, retaining walls over 1 metre in height generally require a building permit and engineered drawings under the Ontario Building Code — budget $1,000–$3,000 for engineering on top of construction. Walls near ravines or property lines can trigger extra review under Toronto's ravine bylaw, so confirm scope before signing.

Questions to ask your contractor

  • Does this wall need a permit and engineered drawings (over 1m)? Engineering cost benchmarks
  • What drainage goes behind the wall (gravel, weeping tile)?
  • Which material are you pricing — armour stone, block, or poured?
  • How deep is the footing/base for our frost line?
