| Item | Typical range | Unit | Source |
|---|---|---|---|
| Ready-mix concrete, 25 MPa strength mix, delivered (GTA plant price)A single published plant price, not a range, and it is before delivery charges, the $7.00/m3 environmental charge, a $2.00/m3 fuel surcharge and 13% HST. CBM's residential R3 25 MPa mix is $248 and its CSA C-4 25 MPa is $260. All prices rise by a $15.00/m3 escalator each January 1. | $245–$245 | per m³ | Canada Building Materials (GTA price list, in effect Jan 15 2026) |
| Garage slab, 20 ft x 20 ft, installed (subcontractor price)2AZ Group's subcontractor rate table, installed prices including materials and labour. The wide range reflects straightforward pours on easy sites against complex work with access issues, slopes or engineering requirements. A standard residential basement floor is $6,000 to $10,000 on the same table. | $5,000–$8,000 | per project | 2AZ Group (GTA subcontractor rates, early 2026) |
| Contractor crew charge-out: finisher / formwork carpenter2AZ Group's GTA labour rate for a formwork carpenter.

| Ready-mix concrete, 30–35 MPa, delivered (GTA)Plant prices before delivery, surcharges and HST: $255 for 30 MPa and $270 for 35 MPa. Strengths above 35 MPa require a minimum load of 3 m3.

| Concrete line pump with operator (residential pours)Rockit says the rate depends on project duration, concrete volume and total hose length, and quotes each job on distance and mix. 2AZ Group prices a trailer-mounted line pump at $800 to $1,200 for a half day. | $500–$1,200 | per day | Rockit Concrete Pumping (Toronto) |
| Concrete finisher wage, Toronto Region (employee, not charge-out)An employee wage, not a contractor's charge-out rate. Job Bank's figures are for the Toronto Region over the 2023-2024 reference period, updated 19 November 2025, from Employment Insurance Survey data. | $28.80–$47.00(typ. $43.58) | per hour | Government of Canada Job Bank - Concrete Finisher, Toronto Region |
The ranking on this page blends each firm's star average with its review count, so the 22 companies in Oshawa are judged on durable reputation. The median company here carries 20 Google reviews.

Ask any local concrete contractor for a current WSIB clearance and proof of liability insurance, and confirm both are active before work starts. ConcreteFinder flags verification signals on each profile, but the coverage documents are worth checking directly.
Permits track scope in Oshawa. Swapping an existing driveway or walkway for a new one in place is typically exempt, while foundations, underpinning and load-bearing slabs need a permit and engineering. Touching the municipal boulevard adds a right-of-way permit from the City of Oshawa. Confirm the permit path before any pour.
Free estimates are the norm for local concrete 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.
The pour window runs Apr–Nov, since fresh concrete cannot go on frozen ground or take a hard frost while curing. Good Oshawa concrete contractors fill up before peak summer, so request quotes early.
For Oshawa, one July 2026 benchmark: ready-mix concrete, 30–35 MPa, delivered (GTA) runs $255–$270 per m³ in the GTA (Canada Building Materials (GTA price list, in effect Jan 15 2026)). Quotes there usually track that GTA range. Add 13% HST, and see the full concrete contractors cost guide.
