Renovation Contractor in Ontario

A renovation contractor (general contractor or main builder) manages your whole project: pricing the job, scheduling and supervising trades like electricians and plumbers, ordering materials, arranging permits where needed, and being the single party responsible for quality and timeline. You pay one contract price instead of coordinating five separate trades yourself.

Hold back 10-15% of the contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp. Do not tell the contractor your contingency figure — it is your buffer, not extra scope budget.

Ask every contractor to break the quote into the same line items: demolition, structural, plumbing, electrical, walls and finishes, fixtures, and a stated allowance for materials you choose. Then compare line by line. A single lump-sum number cannot be compared and cannot be enforced when scope questions come up mid-project.

Usually yes for single-room projects if water and power stay connected to the rest of the home; usually no for whole-home work involving dust-heavy demolition or when the only kitchen or bathroom is out of service for weeks. Ask the contractor to phase the works so one bathroom stays functional, and budget for short-term accommodation on gut renovations.

Hourly rates typically run CAD 50-130 depending on province and city, with most renovations priced as a project including a 10-20% management markup. Mid-range whole-home renovation work commonly lands around CAD 100-300 per square foot in major metros.

Cosmetic work doesn't need one, but municipal building permits are required for structural changes, moving plumbing, most electrical alterations (with inspection by the provincial electrical authority, e.g., ESA in Ontario), and basement legalizations. Unpermitted work commonly surfaces during home inspection at resale and can kill a deal.
