The costs for hiring a general contractor in Montreal vary based on project complexity, materials used, and required labor. Kitchen and bathroom renovations are among the most common projects, and clients can expect typical costs within this range.
What's Involved
A general contractor (GC) manages renovation and construction projects from start to finish. They coordinate all subtrades — framers, plumbers, electricians, drywallers, painters — pull permits, schedule inspections, manage timelines, and ensure the work meets building codes. Hiring a GC is essential for projects that involve multiple trades or structural modifications.
Typical projects managed by a general contractor include home additions, basement finishing, major renovations, structural modifications, and new builds. The GC provides a detailed scope of work and contract, orders materials, manages the job site, and handles quality control throughout the project.
In Canada, general contractors are licensed at the provincial level. In Quebec, a GC must hold an RBQ licence. In Ontario and other provinces, licensing requirements vary by municipality, but professional certifications from associations like the Canadian Home Builders' Association (CHBA) signal quality and accountability.
Factors That Affect Cost
- Project type — A basement finish ($30,000-$60,000) vs. a home addition ($100,000-$250,000+) vs. a full gut renovation ($80,000-$200,000+).
- GC markup — General contractors typically add 15-25% to subtrade and material costs for project management.
- Permits and engineering — Complex projects in Montreal may require architectural drawings, structural engineering, and multiple permits.
- Material selections — The GC procures materials based on your choices; premium finishes increase the budget significantly.
- Project duration — Longer projects mean more management overhead and carrying costs.
- Unforeseen conditions — Older homes in Montreal often reveal hidden issues (asbestos, knob-and-tube wiring, structural deficiencies) once walls are opened.
- Change orders — Modifications to the original scope during construction are the most common cause of budget overruns.
How to Save Money
- Define the complete scope of work before signing the contract — change orders during construction are expensive.
- Set a realistic contingency budget (10-20% of the project cost) for unforeseen issues.
- Get three detailed quotes from general contractors in Montreal and compare scope, timeline, and markup structure.
- Consider a cost-plus contract for smaller projects and a fixed-price contract for well-defined scopes.
- Make all material and finish selections before construction starts to avoid delays and rush-order premiums.
Hiring Tips
- Verify the contractor's licence: RBQ in Quebec, and check for CHBA membership or equivalent credentials elsewhere.
- Ask for proof of liability insurance (minimum $2 million) and WSIB/WCB coverage for all workers on site.
- Request a detailed contract that includes scope, timeline, payment schedule, change-order process, and warranty terms.
- Never pay more than 10% upfront — tie payments to completed milestones.
- Check references from recent projects of similar scope in Montreal and visit an active job site if possible to assess organization and cleanliness.

Do I need permits for a renovation in Montreal?
Yes, for any work involving structural changes, plumbing, electrical, HVAC, or changes to the building envelope. Your general contractor should identify all required permits and handle the application process. Failing to pull permits can result in fines, removal orders, and complications at resale.
