Founded in 1962 as the Canadian division of BritishHawker Siddeley Group, the company assumed the assets of theA.V. Roe Canada Company Ltd.

Hawker Siddeley Canada focused on manufacturing heavy rail cars (hopper and tank cars) and transit vehicles (subway cars, intercity railcars and streetcars). Major clients included:

• Toronto Transit Commission –H series (Toronto subway) (H1 to H5 only as H6 built by UTDC and H3 rebuilt H2 by TTC) cars
• GO Transit – bi-level coaches Series I to II (Series III to IV were jointly built with UTDC)
• Soo Line Railroad
• CN Rail Cabooses
• Canadian Wheat Board – cylindrical grain hoppers
• Saskatchewan Grain Car Corporation – grain hoppers
• Massachusetts Bay Transportation Authority – Orange and Blue line transit cars
• National Railways of Mexico – passenger coaches

Hawker Siddeley Canada headquarters was inMississauga,Ontario. Its formation in 1962 saw the company acquire control of several A.V. Roe Canada subsidiaries including theCanadian Car and Foundry (CC&F) as well as theDominion Steel and Coal Corporation (DOSCO) conglomerate, which included various steel mills, coal mines, manufacturing plants, andHalifax Shipyards. Consequently, Hawker Siddeley had two primary railcar manufacturing plants:

• CC&F factory inThunder Bay,Ontario, for manufacturing railway transit cars, and
• DOSCO factory inTrenton, Nova Scotia, for manufacturing railway freight cars (TrentonWorks), along with the Trenton Forge - the largest forge in North America.

Hawker Siddeley forced its DOSCO subsidiary to close money-losing coal mines and steel mills, subsequently expropriated by the federal and Nova Scotia governments (see:Cape Breton Development Corporation andSydney Steel Corporation). Likewise, CC&F was forced to shed various assets. Halifax Shipyards was sold to Irving Shipbuilding Inc., a subsidiary ofJ.D. Irving Limited, in the 1990s.

Hawker Siddeley Canada's operations were then acquired byKingston-basedUTDC (later sold toBombardier Transportation ofMontreal,Quebec).SNC-Lavalin purchased the railcar business but mothballed the TrentonWorks plant, which was later acquired by the Government of Nova Scotia and sold toGreenbrier. SNC-Lavalin sold the Thunder Bay plant toBombardier Transportation and the Hawker Siddeley Canada name was ultimately dissolved in 2001. Bombardier Transportation was later sold to French rail manufacturerAlstom including the former Hawker plant in 2021.

Rail

Hawker-Siddeley Transportation also produced railway freight cars primarily for Canadian railways and leasing companies during the 1970s and 1980s at plants in Thunder Bay, Ontario and Trenton, Nova Scotia. Today the Thunder Bay plant is owned byBombardier Transportation. The Trenton plant was sold in 1988 to Lavalin Industries and renamedTrentonWorks.The Greenbrier Companies acquired the plant in 1995 but during a serious contraction within the railcar sector in the mid 2000s closed the plant.
