The Toronto and Mimico Electric Railway and Light Company was incorporated in 1890, and operated the Mimico radial line in the Toronto area. The line started operation in 1892 as a short suburban line that later was extended to Port Credit. In 1904, the railway was acquired by the Toronto and York Radial Railway (T&YRR) and became the T&YRR Mimico Division. In 1922, the City of Toronto acquired the T&YRR and contracted Ontario Hydro to manage the four T&YRR lines including the Mimico line. In 1927, the TTC took over the operation of the Mimico line and extended its service eastward to Roncesvalles Avenue. In 1928, the TTC double-tracked the line from Humber to Long Branch and made that portion part of the Lake Shore streetcar line. The portion beyond Long Branch to Port Credit became the Port Credit line, and continued operation as a single-track radial line until its closure on February 9, 1935. This article is more about the Mimico/Port Credit line than about the company that spawned it. Timeline Pre-T&YRR era (1890-1904) Events prior to the merger creating the Toronto and York Radial Railway in 1904 On 16 July 16, 1892, the Toronto and Mimico Electric Railway and Light Company (incorporated November 14, 1890) began initial service between Sunnyside and the Humber River. The electrified line operated along a single track with only open cars, two of which were double-deck. The line used Toronto gauge On July 5, 1893, the Toronto Railway Company acquired controlling interest in the Toronto and Mimico Electric Railway and Light Company, after the latter became insolvent due to a decline in ridership during winter as the line had no closed cars. The ridership on the line at that time was mainly from summer excursions. The TRC introduced two closed cars, both former horse cars that had been motorized, and these were the only closed cars until 1896. On July 10, 1893, the Toronto and Mimico Electric Railway and Light Company extended service from Humber River to Mimico Creek, and further to Etobicoke Creek (Long Branch) on September 29, 1893. The line ran on the north side of Lake Shore Boulevard with passing sidings at Park Lawn Road, Allen Avenue and Royal York Road. The line could now give summer service to Long Branch Park, which evolved into an amusement park in the 1890s. On June 20, 1896, two open, double-deck cars (numbers
