The Metropolitan Street Railway was the operator of the Metropolitan line in the Toronto area that started out as a local horsecar line and transformed itself into an electric radial line extending to Lake Simcoe.
 In 1904, the railway was acquired by the Toronto and York Radial Railway (T&YRR) and became the T&YRR Metroplolitan Division.
 In 1922, the City of Toronto acquired the T&YRR and contracted Ontario Hydro to manage the four T&YRR lines including the Metropolitan.
 In 1927, the TTC took over the operation of the Metropolitan Line to Sutton, and renamed it the Lake Simcoe line.
 In 1930, the TTC closed the Metropolitan Line but shortly reopened the portion between Glen Echo and Richmond Hill operating it as the North Yonge Railways until 1948.
