History

The St. Clair ROW Project
In 2002, the commission began exploring the option of running the 512 St. Clair streetcars on a dedicated right-of-way. The commission authorized an environmental assessment in 2003. City Council gave approval to proceed with the implementation of the right-of-way on St. Clair Avenue West between Yonge Street and Gunns Road in late 2004.[1]
The project was expected to be completed by September 2006. This project faced considerable resistance from local residents and advocates. In August 2005, a Judicial Review ordered construction to be stopped during its review. The Judicial Review ruled in favour of the complainants, but the Divisional Court of Ontario overruled the review in February 2006 after an appeal. The initial projected cost was approximately $48 million. This was later revised to be $65 million. The estimated cost had increased to $106 million by 2010.[2]
The first phase included work between Yonge Street and Vaughan Road. It was completed and operational by February 2007. By December 2009, the portion to Lansdowne Avenue was completed and operational. Construction to Gunns Loop was completed in 2010, and on June 30, full streetcar service resumed on the new right-of-way.[3] The public was treated to free rides on the two PCC streetcars on the opening day.
New large modern glass and metal shelters are used along the entire route. Local information relating to the stop's community is posted in enclosed boards along with route information. Stop names make use of the TTC's own font which is used at most subway stations. Public art installations were installed in late 2010. In total, there are 24 art installations between Yonge Street and Gunns Loop.
Streetcars operated on the completed portion of the right-of-way during construction. Wilson Division supplied shuttle bus service to provide service over the incomplete portion.
