Powering Ontario’s Critical Infrastructure.
Montgomery Industrial Services designs, builds, and maintains high-voltage and electrical infrastructure for Ontario’s most essential projects—from nuclear to municipal.
When It Has to Be Done Right the First Time.
In today’s infrastructure-driven economy, poor workmanship costs time, money—and trust. Our clients rely on us because we deliver safe, scalable, code-compliant results, every time.
Founded in 1992. We’ve evolved from residential work into a leader in Ontario’s electrical infrastructure.
Trusted by Bruce Power, OPG, municipalities, local hydro utilities and major contractors.
Our crews are certified, insured, and trained in high-risk environments like nuclear zones, storm response as well as major capital projects, (pole line related) road widening jobs.
How We Work
Connect with the Right Expert
Call or email our main line. You’ll be promptly connected to the specialist who handles your project type—whether it’s high voltage, municipal lighting, or nuclear infrastructure.
Align Scope & Strategy
We’ll arrange a discovery meeting (online or in-person) to fully understand your needs. From there, we’ll hold a pre-bid kickoff to ensure clarity before preparing your custom, scope-fit proposal.
Execute with Confidence
Once the proposal is accepted, we launch with a kickoff meeting covering schedules, safety, and procurement. Projects are managed with regular check-ins—daily, weekly, or monthly—based on scope.
