Prior to the completion of the Bloor-Danforth Subway line, the TTC was already looking to expand its overcrowded and hectic Yonge Subway line and Eglinton Station terminal. The continued growth and expansion of Metropolitan Toronto meant that a solution would need to be found. In 1961 the first set of plans was drawn up for the Yonge Subway northern extension. These plans were modified several times until 1967 when Metropolitan Toronto accepted the new alignment.
Construction on the Yonge Subway Northerly Extension began in October 1968. This extension would see the Yonge Subway extended from Eglinton Station to Sheppard Station. A decision was made in 1969 to further extend the Yonge Subway to Finch Station. The original stations for this line were Lawrence, York Mills, Sheppard, and Finch.
This north Yonge Subway extension was opened in two parts. First, the extension from Eglinton Station to York Mills Station opened in March 1973. The remaining two stations, Sheppard Station and Finch Station, were opened a year later in March 1974, which coincided with the 20th anniversary of the original Yonge Subway opening.
