Licensed General Contractor Serving Toronto & the GTA

Hiring a general contractor in Toronto is one of those decisions where the upfront cost looks high until you compare it to the cost of self-managing six or eight specialty trades on a residential renovation. A licensed, insured GC carries the responsibility for schedule, budget, code compliance, sub-trade coordination, permit pulls, inspection scheduling, change-order management, and the dozen-plus daily decisions that move a renovation from kickoff to municipal final. At RenoHouse our typical general-contracting engagement runs $40,000 for a minimum multi-trade scope, $150,000 for a standard mid-range project (kitchen and bath plus several rooms), and $350,000 to $500,000 or more for major additions, structural changes, or whole-home rebuilds.

The general-contractor fee structure in the 2026 GTA market typically lands at 15 to 25 percent of the trades cost, baked into the fixed-price contract. That covers project management, supervision, scheduling, permit coordination, weekly client reporting, insurance and bonding, and the warranty exposure that comes with standing behind every sub-trade we hire. Self-managed projects often save the GC fee on paper and then lose it twice over to scheduling collisions, cost overruns from poorly coordinated trades, and the dozens of small mistakes that come from homeowners learning Ontario Building Code in real time.

What a general contractor actually does

A RenoHouse general-contracting engagement starts with a written scope (drawings, finishes specification, schedule, fixed price, change-order procedure, milestone payments), a permit-feasibility review, and a pre-construction meeting where every key decision is locked in writing. During the build we hold daily on-site supervision, coordinate every sub-trade arrival, manage materials delivery and storage, run weekly client check-ins with progress photos in a private portal, schedule every Toronto Building inspection plus separate ESA and TSSA inspections where the scope warrants, and write change orders for every scope adjustment before any work happens.

The trades we coordinate on a typical mid-range project include framing carpenters, drywallers, painters, finish carpenters and millwork installers, a 306A plumber for any fixture or rough-in scope, a 309A Master Electrician working under ECRA/ESA registration for all line-voltage work, a TSSA G1 or G2 gas-fitter for furnace, range, or hot-water-tank relocation, a HVAC mechanical contractor for ductwork modifications, tilers, flooring installers, and roofers or exterior trades where the scope extends past the envelope. On structural scopes we also engage a professional engineer (P.Eng.) for sealed drawings and field reviews.

Permits, compliance, and the inspection lifecycle

Toronto Chapter 363 governs building permits in the city, and any project that crosses $150,000 in declared construction value or touches structural framing triggers Section 11 review. Skilled Trades Ontario regulates the plumber (306A) and electrician (309A) trades. The Electrical Safety Authority requires a Notification of Work for any new circuit, panel upgrade, or rewire. TSSA regulates all gas work in Ontario under the G1/G2 gas-fitter authority. Ontario Building Code Part 9 governs detached and semi-detached housing, Part 3 governs multi-residential. All our sub-trades carry the licences and insurance the law requires, and we pull every permit in the homeowner's name with our staff name listed as agent.

Mid-project inspections happen at framing, plumbing rough-in, electrical rough-in, insulation, drywall (before close-up), and final. Each one is a separate appointment with a Toronto Building inspector, and our project managers schedule them on the city's online portal directly. ESA inspections happen at electrical rough-in and electrical final. TSSA inspections happen at gas connection. Skipping or failing any of these triggers a stop-work order, which costs days or weeks. Our completion rate without a stop-work order is 100 percent across our GTA projects.

Cost factors, what drives the GC fee, and the rebate stack

The general-contracting fee is driven by scope complexity, schedule risk, sub-trade coordination depth, permit complexity, and the inherent warranty exposure of a fixed-price contract. A simple two-trade project (paint and floors) does not justify a GC. A six-trade project with structural changes, multiple permits, and a tight timeline absolutely does.

RenoHouse helps clients access the rebate stack where applicable: Canada Greener Homes Loan up to $40,000 interest-free for envelope and mechanical work, Enbridge Home Efficiency Rebate Plus for air sealing and insulation, Save on Energy rebates for heat-pump and EV-charger work, Toronto Section 7C subsidy for backwater valve installation, and the Multigenerational Home Renovation Tax Credit ($7,500 refundable) where the project creates a secondary suite.

Toronto/GTA neighborhood considerations

• Forest Hill / Rosedale / Lawrence Park (HCD streets): General-contractor scope on heritage requires Heritage Permit before any visible exterior change, lime-mortar repointing spec (NHL 3.5 hydraulic lime — not portland), original window restoration in lieu of replacement on street-facing facade. Project Management premium $40K-$80K beyond base GC fee due to design-review iteration.
• North York / Scarborough / Etobicoke (60s-70s detached): Stable trade-base, GC sweet spot. Standard CCDC-2 or Stipulated Sum contract. Typical project size $180K-$650K. DSS coordination, lead-paint Reg 90/2024 lead-safe scope on any pre-1978 drywall opening, asbestos abatement (Reg 278/05 Type 1-3) coordination on textured ceiling + vermiculite + plaster.
• Mississauga / Brampton / Vaughan (90s+ subdivisions): Production-grade GC, trade-bench depth excellent, lower coordination friction. Stipulated Sum or T+M-with-GMP common. Typical project size $120K-$420K.
• Caledon / King City / Aurora (rural estate): Premium GC scope — septic and well coordination, conservation-authority approval, propane-to-heat-pump conversion, generator standby tie-in. Trade-base thinner (Bolton / Schomberg / Caledon East GC bench), travel-time premium 15-25% baked into trade quotes.
• Downtown condos (King West / Liberty Village / Yorkville): Condo Board Form 1 + Status Certificate + Tarion-style limited warranty on internal scope only (no envelope work). 5pm-10pm only on weekday demo, weekends-restricted on most boards. Premium $35K-$70K coordination overhead vs ground-level.
