Sir
Allan MacNab was the driving force behind the financing of the railway in Canada (and less so in the United States and England), although he was pushed out of the company in 1854. Entrepreneur
Samuel Zimmerman was instrumental in promoting its construction and
Roswell Gardinier Benedict, a friend of Zimmerman's, was the assistant chief engineer and later the chief engineer. Although it received the first charter to operate in Canada West, it was the second to begin operation. Due to the length of time to construct its lines, it was beaten into service by six months by the
Ontario, Simcoe and Huron Railway. The original line completed in 1853–54 connected
Niagara Falls to
Windsor, running by way of
Hamilton and
London. In 1855 two important additions were made: the opening of the branch to
Toronto and rail connections over the newly opened
Niagara Falls Suspension Bridge. Further branches were opened to
Sarnia and communities in the
Bruce Peninsula. MacNab's dismissal was directly related to a proposal from Zimmerman to purchase assets in the Niagara area, the Erie and Ontario Railway, a shortline around Niagara Falls; and the Niagara Harbour and Docks Company. In 1853, threatening to use these assets to start a competing railway with a shorter line between Niagara and Detroit, Zimmerman presented to the GWR board a proposal to instead sell them to the GWR. MacNab was against the proposal; it failed. As a consequence, GWR managing director
Charles John Brydges, who had negotiated a purchase agreement with Zimmerman would engineer MacNab's dismissal from the board. In 1855, traffic has risen to the level that GWR made plans to double-track its lines. As this required Legislature approval, Zimmerman was retained to secure its approval through his influence. In turn, Zimmerman would receive the contract to double-track the line. A clause of the approval granted an exemption for the GWR from the regulation for all trains to stop at all drawbridges. The GWR used multiple stations in Toronto. Its first was a depot at the Queen's Wharf, then it secured the use of the Canadian Northern station at York Street. It built its own station at Yonge Street and the Esplanade in 1866. The GWR also used the Union Stations built in 1858 and 1873, built by the
Grand Trunk Railway. The railway merged with the Grand Trunk Railway in August 1882, and ultimately became a major part of
Canadian National Railway's southern Ontario routes. The majority of the mainlines remain in use. The main Niagara Falls–Windsor line is now the Canadian National Railway's Grimsby Subdivision, Dundas Subdivision, Chatham Subdivision, and CASO Subdivision. The Toronto branch is the Oakville Subdivision, and the Sarnia branch is the Strathroy Subdivision (which also includes a short piece of the mainline, from
London to
Komoka).
