Most Toronto basement renovations cost between $35,000 and $95,000 in 2026. A basic finish for a rec room or office runs $25,000 to $45,000. A finish with a bathroom runs $45,000 to $75,000. A legal basement suite runs $80,000 to $140,000+. That works out to about $35 to $95 per square foot. Integra gives you a fixed written price upfront, and we suggest a 15% to 20% cushion for older homes.
Yes. A legal basement apartment (secondary suite) in Toronto must meet the Ontario Building Code: a minimum 1.95 m (6 ft 5 in) ceiling, an egress window, fire separation between units, interconnected smoke and CO alarms, independent HVAC, and a separate electrical sub-panel. A compliant suite rents for about $2,300 to $2,600 a month in Toronto. Integra designs, permits, and builds it fully to code.
Yes, in most cases. The City of Toronto requires a building permit for new plumbing, electrical, HVAC, structural work, a separate entrance or a legal suite. Permit fees plus architectural drawings usually total $3,000 to $6,500, and approval takes about 2 to 8 weeks. Cosmetic work like paint does not need a permit. Integra handles the full permit process for you.
A finished basement in Toronto typically returns 70% to 75% of its cost at resale. A legal rental suite goes further, adding about $2,300 to $2,600 a month in income, so it can pay for itself over time and help your home sell faster in the GTA market.
A basic basement finish takes about 4 to 6 weeks. A finish with a bathroom takes 6 to 10 weeks. A legal basement suite takes 10 to 16 weeks, including permit time. Integra maps a clear schedule before any tools arrive and keeps you updated as the work moves.
Yes, and we always do. Before any framing, we test for moisture and handle waterproofing: a sump pump with battery backup, a dimple-mat membrane and proper drainage. Finishing over a damp basement is the costliest mistake in Ontario, so we keep it dry first, then build.
Yes. In older Toronto homes we lower the floor with underpinning or bench footing to reach the legal 1.95 m (6 ft 5 in) ceiling height a suite needs. This structural work typically adds $20,000 to $60,000, and Integra handles the engineering, permits, and inspections.
Yes, in most cases. The work stays downstairs, so your main floors keep running. We seal off the stairwell with dust barriers, protect your floors, and clean the site daily, so daily life upstairs carries on with little disruption.
Pick a licensed, insured contractor who waterproofs first, pulls permits, builds suites to code, and gives a fixed-price written contract with a clear payment schedule and no large upfront deposit. Check Google and HomeStars reviews. Integra Renovation meets every one of these standards.
Yes. Every Integra basement renovation is backed by a workmanship warranty, with callbacks answered inside the warranty window, and we offer financing options. Ask about our free design consultation and free in-home estimate when you call +1 519 981 8478.
