A new chapter begins for MSB Mechanical.
For years, we've built our reputation in Toronto, delivering integrated mechanical construction solutions our clients can count on. In 2024, we joined forces with Kolostat, bringing together nearly a century of HVAC expertise and a shared commitment to delivering high-performance building mechanical systems.
As of July 1, 2026, that partnership has come full circle. MSB Mechanical and Kolostat are now officially one entity: Kolostat.
We're also proud to unveil a new visual identity reflecting our affiliation with Climater, a leading building performance group with more than 3,000 employees across Canada and Europe.
For us, this means delivering smarter, higher-performing solutions than ever. For you, it means access to a broader network of experts.
The name on the door is changing. The people and the standards behind it are not.
Follow Kolostat to stay connected and be part of what's next.
