The OC Transpo BRT system in Ottawa, Canada, was introduced in 1983. The first element of its BRT system was dedicated bus lanes through the city centre, with platformed stops. The introduction of exclusive separate busways (termed 'Transitway') occurred in 1983. By 1996, all of the originally envisioned 31 km Transitway system was in operation; further expansions were opened in 2009, 2011, and 2014. As of 2019, the central part of the Transitway has been converted to light rail transit, due to the downtown section being operated beyond its designed capacity.
