O-Train west extension delayed by Canada Day flood damage

Flooding from the city's Canada Day storm damaged parts of the under-construction west O-Train extension, forcing repairs and raising new uncertainty about whether the project's scheduled summer 2027 opening can still be met.

Transit Services general manager Rick Leary told city council on July 16 that the July 1 storm flooded multiple sections of the Stage 2 west extension, damaging electrical equipment, track infrastructure, ballast sections of the track, troughs, and cabling that will need to be repaired before construction can continue. Affected areas include the guideway near Moodie Drive, the tunnel along the Kichi Zibi Mikan, and stations at New Orchard, Sherbourne, Queensview, and Pinecrest.

The city's contractor, East-West Connectors, is carrying out a comprehensive assessment of the damage. "It's also too early to comment on how long the repairs may take or what this will mean to the overall project's schedule," Leary said. Council is expected to receive an updated schedule in early 2027 after the damage assessment progresses.

The news disappointed transit advocates. Brooke Anderson, founder of the Carleton University branch of Ottawa Transit Riders, said the delay shows the need to design transit infrastructure to withstand increasingly severe weather. "In this world that we live in, something that can't withstand severe weather isn't reliable because we are going to have that weather," she said. The west extension will extend O-Train service from Tunney's Pasture to Moodie Drive and Algonquin College when it eventually opens.
