Costs for foundation and underpinning work in the Mimico area depend on scope, finish and access. As a benchmark from our July 2026 GTA data, city of Toronto minimum building permit fee (2026) runs $214.79–$214.79 per permit (minimum; underpinning is charged per linear metre on top) (City of Toronto Building Permit Fee Schedule); building permit line as quoted by contractors runs $1,000–$1,500 per project (Nusite Group (Toronto underpinning contractor)). Expect Mimico quotes to trend higher where site access and disposal are limited. Add 13% HST.
| Item | Typical range | Unit | Source |
|---|---|---|---|
| Underpinning a 1,000 sq ft basement lowered by 2 feet (total project)Nusite's worked example at their own $50 to $80 per square foot underpinning rate, over a four to ten week timeline. Permits, engineering, waterproofing, plumbing and finishing are all priced on top. | $50,000–$80,000 | per project | Nusite Group (Toronto underpinning contractor) |
| Structural engineer hourly rate (Toronto/GTA)An hourly consultation rate for advice only. SEPCO puts Toronto and the GTA at the top of the provincial band, $150 to $300 per hour, for highest demand and fastest turnaround. | $150–$300 | per hour | SEPCO Engineering |
| Basement underpinning - structural work onlyStrong Basements' Toronto average for the structural work alone. Elsewhere on the same page they put the market rate for a professionally managed, fully insured project at $350 to over $600 per linear foot, with crawlspaces often at the higher end. Cost varies with soil conditions, depth of lowering, the underpinning method (non-shrink, overpour, L-shape, bench footing, engineered bench) and structural requirements such as load posts and beams. The flat $650 ceiling this guide used to show is not on their page. | $350–$480 | per linear foot | Strong Basements |
| Basement underpinning - turn-key project (engineering, permits, waterproofing, plumbing, new slab)Strong Basements' all-in figure for a basement-lowering project, the same sentence that carries their per-linear-foot rate. Their worked example is a 600 sq ft basement lowered by 2 feet at $62,900 all in. The $50 floor and $105 ceiling this guide used to show are not on their page. | $80–$100 | per sq ft | Strong Basements (low end: Nusite Group) |
| Bench footing - priced by floor areaBench footing keeps the existing footing and steps the new floor in from the wall, so it is cheaper than underpinning but gives up perimeter floor area. Nusite's timeline is four to eight weeks. | $35–$60 | per sq ft | Nusite Group |
| City of Toronto minimum building permit fee (2026)A floor, not a range, and not the whole permit cost. The City charges $214.79 minimum on all work in 2026 and then calculates the permit as a service index times floor area; examination and inspection time is $92.79 an hour. Engineering, drawings, revisions and plumbing permits are extra. | $214.79–$214.79 | per permit (minimum; underpinning is charged per linear metre on top) | City of Toronto Building Permit Fee Schedule |

Free estimates are the norm for local foundation contractors, usually after a short site visit. ConcreteFinder does not book them for you; it ranks the companies and publishes how to reach each one.
Before hiring, request a live WSIB clearance and a liability certificate, and verify the dates. ConcreteFinder surfaces verification signals on every Mimico profile, yet the actual insurance paperwork should be confirmed with the foundation contractor first.
Yes. Underpinning, bench footings and any structural foundation work in Mimico need a building permit plus stamped drawings from a licensed Ontario structural engineer under the Building Code, and the city inspects in stages. That process is why an underpinning job is scoped very differently from flatwork, and because it is excavation work it runs year-round.
A solid Mimico quote itemizes site prep, mix and thickness, reinforcement, finish, jointing and disposal, then the payment schedule and warranty. A vague one-line price is a red flag, so compare like-for-like scope across three bids.
Because foundation and underpinning work in Mimico is interior or below-grade work, it runs year-round rather than waiting on the pour season. The best crews still fill up in busy stretches, so ask early.
