Aecon has a rich history that spans more than a century. In fact, Aecon’s history can be traced back to 1877, when Scottish immigrant Adam Clark started a plumbing and gas fitting business in Hamilton, Ontario. Since that time, Aecon has grown into one of Canada’s largest and most diverse construction and infrastructure development companies.
Throughout the years, Aecon has been involved in the building of some of Canada’s most important landmarks, including the CN Tower, St. Lawrence Seaway, Highway 407 Express Toll Route, Vancouver Sky Train, and the Montreal-Trudeau International Airport, to name just a few.
Aecon’s predecessor companies include some of Canada’s most renowned construction names. Over the years, companies such as The Foundation Company of Canada, Jackson Lewis, Lockerbie and Hole, Bannister Pipelines, Nicholls-Radtke, Pitts Engineering Construction, and Armbro Construction have come together to form what we now know as Aecon.
