The 36-kilometre (22 mi) bus corridor will run from downtown Oshawa to Scarborough Town Centre in Toronto, mainly along Durham Region Highway 2 (formerly Ontario Highway 2) in Durham Region and Ellesmere Road in the Scarborough district of Toronto.
Metrolinx expects construction of segments in Durham Region to begin in 2022, and estimates that the BRT will carry 38,000 passengers per day by 2041.
The DSBRT would continue further east along Kingston Road crossing the Rouge River into Durham Region, passing through the municipalities of Pickering, Ajax and Whitby, and terminating in downtown Oshawa.
In August 2021, the governments of Canada, Ontario and Durham Region reached a funding agreement to build this portion of the DSBRT within Pickering.
Outside the pinch point, Metrolinx proposes a six-lane road including two centre-median lanes dedicated for buses.
[9] In 2021, Durham Region along with the provincial and federal governments have pledged $58.7 million to build sections of the BRT in Ajax, Whitby and Oshawa.
Along the centre-median section, transit stops would be located at signaled intersections and have raised and barrier-protected platforms.
[12] On June 15, 2007, Ontario premier Dalton McGuinty announced a $16 billion transit plan called MoveOntario 2020.
One component of the plan was a bus rapid transit line on Highway 2 between Pickering and Oshawa.
[13][14] About 2010, Durham Region was considering light rail transit to replace the Highway 2 BRT all the way east to Courtice Road in Clarington and west into Scarborough in Toronto.
