The Ontario and Quebec Railway (O&Q) was a railway located in southern and eastern Ontario, Canada. It was initially chartered in March 1881 by managers of the Canadian Pacific Railway to run between Toronto and Perth, where it would connect, via a short branch line, to the CPR-controlled Brockville and Ottawa Railway. Construction began in 1882, and the line was completed in August 1884. Starting in 1883, CPR began using the O&Q to build a network in southern Ontario to compete with the Grand Trunk Railway. The O&Q leased the Credit Valley Railway, Toronto Grey & Bruce, London Junction Railway and some sections of the Canada Southern Railway, building an extensive portfolio of routes. In August 1888 they provided a direct through route to Montreal by leasing the Atlantic and North-west Railway and connecting it to the O&Q via an extension from Smiths Falls to the Quebec border. A final major extension was the West Ontario Pacific Railway (WORP), which connected the Credit Valley in Woodstock to Windsor and the US border. The WOPR opened in 1887, and was immediately leased to the O&Q. The western end of the O&Q currently forms the CPR mainline from Detroit and Windsor to Toronto, running through North Toronto and into the CPR Toronto Yard in Agincourt. The route eastward remains in limited use through Peterborough and on to Havelock where it serves several mines and quarries. However, most of the traffic between Toronto and Perth was redirected to a new CPR line running along the shoreline of Lake Ontario, the Campbellford, Lake Ontario and Western Railway. This turns northeast at Kingston to meet the O&Q at Perth, where the original O&Q forms the rest of the CPR mainline to Montreal. The section from Glen Tay and Tweed was abandoned in 1971, and then from Tweed to Havelock in 1988. This section is now a portion of the Trans Canada Trail. The section from Toronto to Smiths Falls, now known as the Havelock Subdivision, has seen interest by VIA Rail for passenger service as their High Frequency Rail Project. The section from Perth to Quebec operates as the Winchester Subdivision, from Woodstock to London as the Galt Subdivision, and from London to Windsor as the Windsor Subdivision. The North Toronto Station, the main O&Q passenger station in Toronto, is now use as a flagship LCBO. History The railway had received a charter in 1881,
