What Is the Average Home Extension Cost in Montréal?

[trossconstruction]

I'm planning to expand my house and would like to understand the current home extension cost in Montréal. I'm considering adding extra living space, but I know pricing depends on design, materials, permits, and labor. If you've recently completed a home extension in Montréal, QC, Canada, could you share your experience and approximate budget? I'm also interested in finding experienced contractors who provide quality craftsmanship and transparent pricing from start to finish.
