Evidence of corrosion and concrete delamination in St. Laurent O-Train tunnel: Amilcar

Trains are temporarily skipping the St. Laurent Station along the O-Train line on Friday while crews conduct inspections on the ceiling tiles.
An inspection of ceiling tiles at the St. Laurent LRT station has found evidence of corrosion and possible damage to concrete, prompting OC Transpo to suspend train stops at that station Friday.
OC Transpo says following a regular visual inspection early Friday morning, "it was observed that a few of the suspended ceiling tiles above the platform were disrupted."
"Following our standard operating procedures, there will be a detailed inspection carried out to assess the cause," Richard Holder, director of Engineering Services, said in a memo to council.
"In order to allow staff to set up the necessary work area to conduct the inspection, St. Laurent Station will be skipped."
Shuttle bus service is available to transport passengers between St. Laurent and other stations along the O-Train line.
In an update Friday evening, Transit Services General Manager Renée Amilcar said there was evidence of corrosion on some of the ceiling panels in the tunnel and potential delamination to the concrete.
"Engineers are continuing their inspection of the suspended ceiling and the concrete above both the north and south platforms," Amilcar wrote. "Infrastructure and Water Services Department engineers will provide recommendations this evening on the best course of action. As always, we will be making decisions out of an abundance of caution with the safety of our customers being the priority."
