The Confederation Line (O-Train Line 1) continued to suffer from reliability issues throughout the first quarter of 2020. This is in contrast to the Trillium Line, which has a lower ridership and different technology, but generally good reliability. In response to this, and due to lower ridership in 2020, OC Transpo has scheduled several temporary closures of Line 1, allowing Rideau Transit Maintenance to work on the line and improve its reliability. During maintenance, the R1 bus route replaces train service.
