How does YardGrade rank retaining wall contractors?

YardGrade tracks 105 retaining wall contractors working across Canada, with a median 4.86★ Google rating over 3,130 reviews. In the Toronto market, installed retaining wall construction typically runs $25–$65 per sq ft of wall face, CAD according to Project Landscaping (Ontario cost guide, updated Mar 2026). YardGrade ranks every company by verified review data and verification checks, never paid placement, so the shortlist below reflects real reputation.

Rankings can't be bought. YardGrade scores each company with a Bayesian-adjusted Google rating, which weighs review volume so a 5.0 on three reviews does not outrank a 4.8 on three hundred. We then add small verification boosts for an active website, a listed phone number and real project photos. Across our dataset, 82% of rated retaining wall contractors clear 4.8★, so ranking gaps are meaningful. Positions update as new review data lands. Read our full methodology.

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?

When is the best time to book retaining wall construction?

The retaining wall construction season runs Apr–Nov. Reputable companies book several weeks ahead in peak months, so request quotes early; shoulder-season bookings often win better pricing.

Do I need a permit, and is sales tax included in retaining wall construction quotes?

Most posted prices exclude tax, and the rate depends on the province. Sales tax varies by province — Ontario adds 13% HST, Alberta and BC add 5% GST. Permit needs depend on scope and municipality: routine work rarely needs one, but driveway widening, boulevard work and retaining walls over 1 metre generally require municipal approval a reputable contractor handles.
