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.
