About

Modern Niagara builds and maintains the systems inside large buildings. Its mechanical work covers HVAC piping and plumbing systems, sheet metal fabrication and installation, commissioning and quality assurance, and design-assist and professional services. Its electrical work covers institutional, commercial and industrial systems, municipal and public utility services, automation, and emergency and planned maintenance. On top of those sit building controls — building automation systems, building intelligence and master systems integration, and energy management — and an energy practice covering decarbonization, renewable natural gas, and the grants and incentives that fund such projects.

The company's own framing is a combination of capacity and agility: large enough for the biggest and most complex jobs, able to change course mid-project. It also runs a substantial trades workforce and apprenticeship pipeline, with student and co-op programmes alongside skilled-trades recruitment.

It operates from Vancouver, Calgary, Edmonton, southwestern Ontario, Toronto and Ottawa. The Ottawa business has served that city since 1959 and includes more than 250 electricians on its own.
