Line 1 (O-Train)

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.
