The closures are to allow for the TTC to continue work on completing work related to the opening of the second platform at Union Station.
While work takes place, subway service will continue on the rest of the Yonge-University-Spadina line: from Union to Finch on the Yonge Line, and from St. Andrew to Downsview on the University-Spadina section.
Customers who use the University-Spadina portion of the line and wish to connect to portions of the Yonge Line are encouraged to transfer to the Bloor-Danforth Line at St. George station, to the 506 Carlton car at Queen’s Park, to the 505 Dundas car at St. Patrick station, or the 501 Queen car Osgoode station. Transfers to the 504 King car can be made at St. Andrew station, but as this is where southbound subway trains will be ending their runs, so the station may get crowded. Transfers can be made from the streetcars to the 6 Bay bus (which runs south to Union) or to the Yonge Line at College, Dundas, Queen, or King stations.
Service will resume on April 13th, 2015, and continue until the end of service on Friday April 17th, 2015. Service will then resume again on April 20, 2015.
These closures have now become almost commonplace for this portion of the line, but should finish in the near future.
