Line 1 (O-Train)
light rapid transit line in Ottawa, Ontario
Line 1 (French: Ligne 1), formerly known as the Confederation Line (French: Ligne de la Confédération), is a light rail line operated by OC Transpo in Ottawa, Ontario, Canada, part of the city's O-Train system. It opened on September 14, 2019, and is O-Train's second line. It operates on an east–west route, with a segment under Queen Street in the downtown core, complementing the north–south Line 2 that operates to the west of the downtown core.
The project was unanimously approved by the Ottawa City Council on December 19, 2012, with the contract being awarded to Rideau Transit Group. Construction began in 2013, as originally scheduled. At a cost of CA$2.130 billion, the first stage of the line was the largest infrastructure project awarded in the history of the city before being surpassed by the Stage 2 extension of the line, which was projected to cost $4.66 billion.
History
Having had several plans for a metro system already for decades, in 1976 it was decided to start developing a project called Transitway, a bus rapid transit system. The Transitway was intended as a temporary solution in anticipation for urban rail and the first section eventually opened in 1983. As passengers numbers were rising, the decision was made to upgrade parts of the bus system to rail transport.
The Confederation Line rail project was approved unanimously by the city council on December 19, 2012, after many years of debate on a rapid transit network for the city.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
