Entera was established in April 2006 as a joint venture between two of Ontario’s largest utility services providers, Black and McDonald Ltd and Robert B. Somerville in response to a Toronto Hydro Unit-Price Contract RFP.  This joint venture was designed to leverage Black and McDonald’s capabilities in overhead and underground electrical construction and Robert B. Somerville’s strong experience in underground heavy civil construction.

Today Entera is one of the GTA’s leading providers of both overhead and underground electrical utility services, civil utilities construction, engineering design, and trenchless technologies (directional and auger bore). Toronto Hydro remains our principal client. In addition Entera has worked with Bell, Rogers, Toronto Water, various business improvement associations throughout the area, as well as with private business.

We are committed to continually working safe, in a quality manner, and with a minimal amount of disturbance to its customers.
