  History of Bot Construction  

Bot Construction was founded by Silvio Bot, in 1957, in Oakville, Ontario, beginning as a small concrete forming company serving the local market. Over the decades, under his leadership, Bot expanded its services and operations, province wide and beyond, to become one of Ontario's largest privately owned and operated heavy civil engineering and construction companies and a leader in the transportation infrastructure sector.

The company grew in step with the strong demand for construction services that marked the expansion decades of the 1950s and 1960s. A skilled tradesperson with an entrepreneurial vision, Silvio Bot took his operations beyond the Highway 401 corridor, to build highways connecting the manufacturing heartland of central Ontario to commercial markets and population centres in other regions of the province. The expertise in large earth and rock works and structures, for which Bot Construction is known today, was gained building roads through the granite bedrock and muskeg swamp of the Precambrian Shield of northern Ontario during these decades.


By the close of the 1970s, the scope of our work had expanded significantly. Our portfolio ranged from construction of major urban expressways and bridgeworks, such as projects along the E.C. Row Expressway through Windsor, Ontario, to heavy civil works in northern Quebec. It was during this period that Bot became one of the first companies to set up camp at James Bay, Quebec, to begin the work of building the first phase of the La Grande Hydroelectric complex. This work involved building access roads to open the location for the La Grande facility, followed by the construction of 31 dykes and dams, and spanned the decade.

The history of Bot Construction is also rich with stories of Canada's far north. During the 1990's, we undertook the complex logistics of moving materials and equipment down the Mackenzie River, through Inuvik to Tuktoyaktuk and out along the Arctic coast line, to build short range radar stations, under contract with the Canadian Department of National Defence. The installation work was completed over a distance of 1,000 km from the Alaska border, east to Coppermine, Nunavut.
