Wireless services were restored Thursday morning for Telus customers on Montreal’s South Shore, after an outage affected their ability to call 911. “Damage to an aerial fibre-optic cable caused a wireless service disruption in Châteauguay and surrounding areas in the evening on Nov. 4,” the company said. “Telus teams were quickly mobilized and have been working diligently to restore service as soon as possible.” The outage began at 2 p.m. Wednesday and affected 911, text, data, and voice services for customers in Châteauguay, Mercier, Léry, Kahnawake, Saint-Rémi, and Saint-Constant, according to a message on the Telus website. “In the meantime, Telus had activated emergency roaming through another provider’s network, allowing affected customers to access essential wireless services, including voice calls, text messaging and limited mobile data, where coverage is available,” the telecommunications company told CTV News. Bell customers in Châteauguay may also have experienced a disruption of its mobility services, the company confirmed on social media. However, it did not specify which services were impacted. “We are working to restore service as quickly as possible and expect it to be restored overnight,” the company wrote. “In the meantime, we recommend that customers enable wi-fi calling where possible.” CTV News is a division of Bell Media, which is part of BCE Inc.
