The Hamilton Street Railway commonly known as the HSR is a public transport agency in Hamilton, Ontario, Canada. The name is a legacy of the company's early period, when public transit in Hamilton was primarily served by streetcars. Although streetcars are no longer used in the city today, the HSR operates bus and paratransit services, with a ridership of 21 million passengers a year. The HSR uses the Presto card as its method of fare payment, allowing for connections with GO Transit and other transit systems in the Greater Toronto area. History From 1873 to 1889, the HSR was owned by Lyman Moore and operated as a private business. In 1889 HSR was sold to Hamilton Cataract Interests, later known as Dominion Power and Transmission Company. The HSR was later acquired by Ontario Hydro. Provincial ownership ended in 1946 when HSR was bought by Canada Coach Lines. CCL was purchased by the city of Hamilton in 1960. Hamilton-Wentworth Region began ownership of CCL and HSR in 1977, and in 2001 regional amalgamation placed its ownership back to the city of Hamilton.
