The company was founded in the early 1900s and focused on small ship repair as well as small craft construction. It is possible that the company also got into the sales of motor vehicles in the early 1930s. The company saw a large boom during the
Second World War the construction of a number of small harbour patrol craft as well as refitting and maintenance large numbers of Royal Canadian Navy ships, notably
corvettes. Canadian ships refitted at Thompson Brothers included
HMCS Sackville,
HMCS Ville de Quebec and
HMCS Barrie. The yard grew to occupy much of the west bank of the
Mersey River (Nova Scotia) in Liverpool's downtown. After the war, the company became Steel and Engine Products Limited (STENPRO) and worked mainly in fishing boat construction, repair and supply. The yard was eventually bought by
Irving Shipbuilding; and closed in September 2004. ==See also==
