About the Partnership
OC’s vision is clear – we seek to elevate the collective consciousness of the construction industry to align with that of a modern and ever-changing society.
  • We believe construction and real estate are among the few remaining major sectors of our society that still operate on the premise – “we’ve always done it that way.”
  • We seek out clients and partners who share our values. Ehvert was founded with the same vision with a focus in the Critical Facility sector in both Canada and the US.
  • The combined firms operate from a shared vision to challenge the status quo, employ a robust construction management platform of professionals and technology, and have a proven track record of executing complex critical facilities projects for both the government and private sectors.
About Event
Ehvert has been providing engineering, construction and operations services for complex and mission critical facilities since 1988. From Ehvert’s head office in Toronto, Ehvert has implemented projects throughout Canada, the United States and Europe.

Ehvert is a single source service provider of building and IT infrastructure to corporations and institutions in the public and private sectors. Ehvert offers holistic solutions and is able to provide design-build-operate services that cover all segments of a facility from the initial design to the buildout of a criticial facility, through to technology relocation, integration, and ongoing systems support.
