For the purposes of this comparison, we will use the numbers and stats from when the Stage2LRT expansion is completed in Ottawa in 2023.
Ottawa in 2023 will feature 42 stations and 64 km of track.
Montreal in 2018 has 68 stations and 69km of track. (plans to expand the Blue line will add 5 stations and 7km of track).
Toronto in 2018 has 75 stations and 77km of track. (construction in progress will add another 22 stations and 19km of track).
Both Montreal and Toronto are either expanding or have plans to expand their service, so these numbers will change by 2023.
