One of Ottawa’s top engineers is sharing concerns about the O-Train west extension after damage from a severe storm has slowed work and forced repairs.
According to the memo shared to councillors from Richard Holder, the director of the rail construction program, there are ongoing inspections being done to understand how severely damaged equipment is.
An external consultant is looking at the overall schedule for the Stage 2 West Extension to determine the timelines for the project after the Canada Day event. Holder says the report is expected to be ready in early 2027.
“This includes looking at many ways to mitigate project timelines, including the potential for a staged opening,” he adds. “However, this is still a very preliminary option that must be fully examined and any conclusion to this effect is premature.”
Construction of stations, guideway, track and roadway was underway when the surprise deluge dumped record amounts of rain on the city. When complete, the west extension will have 15 more kilometres of rail and 11 new stations. It will link Tunney’s Pasture to Algonquin, and bring on Line 3 that will link Trim to Moodie.
“As shared at council, preliminary information does indicate that a section of the line in the Moodie Station area will require repairs to electrical equipment, sections of track and ballast and other infrastructure,” Holder wrote in the update.
On July 1, intense flooding closed roads, cancelled Canada Day celebrations. Firefighters responded to over 700 reports of downed wires and electrical hazards, officials detailed.
According to Environment Canada’s data, 118.4 millimetres of precipitation fell on Canada Day. This is about double the previous record — 58.9 mm — that was first set in 1959 at the Ottawa International Airport.
Ottawa’s mayor said the city has 5,800 reports of flooded basements more than a week after the “historic event.”
Officials have been on at the stations where damage was reported and meeting with the east-west connectors to oversee the repair and the completion of the work after the rain.
A further update on the situation is expected at the next transit committee meeting.
