About Us
About us
MSH Group
MSH Group is a privately owned construction company serving Toronto and the GTA. We handle general contracting, design-build and installation services under one team, with our own in-house engineers preparing the drawings our own crews build from — so nothing gets lost between the design and the finished project.
What We Do
We provide general contracting, design-build, and installation services for residential, commercial and institutional projects, covering electrical, mechanical and HVAC systems alongside full project management from permits through to final inspection.
Why Clients Work With Us
Most construction projects hire a design firm for the drawings and a separate contractor to build them. When the two have never worked together, small details get lost between the page and the site, leading to change orders, permit delays, and disputes over whose mistake caused the problem. MSH Group closes that gap by keeping engineering and construction inside one company, so drawings are built with real construction conditions in mind from the start.
