The Demstos
Advantage
-
Robot Demolition Unit On Staff
Remote-controlled demolition for confined spaces, live buildings, and environments where conventional equipment can’t go. A real differentiator in the GTA market.
-
16 Years of Hands-On Experience
Not a project manager flipping paper — a crew that has been in the building. We’ve seen the surprises and know how to handle them.
-
GC-Friendly Operations
Clean documentation, accurate scheduling, and clear communication. We know what GCs need to keep their project moving — and we deliver it without being asked.
-
Full Compliance, No Exceptions
Ontario OHSA, MOL Type 3 protocols, bid bonding, CPL insurance. Every job is properly documented. You’ll never get a call from an inspector because of Demstos.
