Construction of a new lower level station at Queen and Yonge will close roads in the area for an extended period according to a new blog article from Metrolinx. Between early 2023 for about four and a half years, Queen street will be completely closed from Victoria to James Street.

James Street will also be closed as well as a portion of the west side of Victoria Street.
Streetcars will divert both ways around the construction site via Church, the Richmond/Adelaide pair, and York. This will require York to become two-way at least south to Adelaide Street (it is two-way only from Queen to Richmond), and new track will have to be installed. Although the map above shows partial occupancy of Victoria Street, it is not clear whether the tracks, long out of use thanks to construction at St. Michael’s Hospital and at Massey Hall, will finally be reactivated.

Reconstruction of Adelaide Street is already in the City’s plans for 2022. Originally, when I asked about the scope of work, the feedback I received from the TTC was that this would only involve track removal from Charlotte Street (east of Spadina) to Victoria. However, with these diversion plans it is clear that new track will be required at least to York Street.
An obvious question here is what plans Metrolinx has for Osgoode Station, and whether a Queen diversion west of York will be required. It is conceivable that the Adelaide trackage may yet live again further west. There will also be construction effects at Queen/Spadina and King/Bathurst. I have written to Metrolinx asking when details of these projects will be available so that the entire plan for downtown construction will be clear.

A further issue is that there is a major reconstruction of King Street planned in 2023. This would have to be well out of the way before Queen Street could be closed. If there will be track on Adelaide to which a connection could be provided at York, a new east-to-north curve would be an obvious addition at King.
More generally, there should be a plan for the future use of downtown streetcar track to support the various diversions needed for construction and to restore some of the flexibility in streetcar operations that has been lost over the years as less-used bits of track fall victim to various construction projects. A list of potential locations includes:
- Adelaide Street from Charlotte eastward, not just from York, including connecting curves at York.
- An east-to-north curve at King and York.
- Reactivation of track on Victoria between Queen and Dundas.
- Addition of curves in the SE quadrant at Church and Carlton (reconstruction is planned there in 2022).
I have written to the TTC asking what their plans are.
Too often, chances to improve the network have been missed when track is rebuilt “as is”. This is an excellent chance to rectify past oversights.
A further issue in all of this will be the effect of redirected streetcar (and other) traffic on the cycling network downtown. I will seek info about this from the City of Toronto.
I will update this article when I receive additional information from Metrolinx and the TTC.
