Seaboard/Harmac Corporate History

Seaboard/Harmac Transportation group was incorporated in 1964 as Seaboard Liquid Carriers with one truck and trailer transporting Petroleum products throughout Cape Breton, Nova Scotia. Through the 1960’s, 1970’s and 1980’s, Seaboard continued to grow by acquiring various small trucking companies in Nova Scotia. 

Seaboard Liquid Carriers became know in the 1990’s as Seaboard Transport Group as it diversified its business to include the specialization in petroleum and bulk mining commodities along with a specialized freight division.  In the mid 1990’s, Seaboard Transport Group solidified its presence as a leader in transporting bulk petroleum with the acquisition of Lake City Transport.

In 1998 Harmac Transportation was purchased which resulted in Seaboard becoming a bulk carrier with coverage from Ontario to Newfoundland with many transport lanes throughout the United States. Harmac Transportation was at that time known as a leader in the petroleum transportation industry in Ontario. It was during this purchase that the marketing image became Seaboard/Harmac. This new image emphasized the combining of two great bulk liquid carriers and further solidified Seaboard/Harmac becoming a leader in the transportation of bulk petroleum and chemical products in Eastern Canada.

The growth of the company has continued with the purchases of Great Western Resources, a dominant propane carrier in Ontario, and the purchase of Tudhope Cartage, a major petroleum carrier in both Ontario and Quebec.  Expansion has continued into the United States with the purchase in 2006 of A.J. Weigand, a bulk chemical carrier located in Bolivar, Ohio with a terminal in South Carolina.
