In an update on Monday afternoon, London Drugs said that as a necessary part of its internal investigation, its phone lines have been temporarily taken down and will be restored as soon as the investigation permits it.

"In the interim, Pharmacy staff are on-site at all London Drugs locations to support customers with urgent pharmacy needs. We advise customers to visit their local store in person for immediate support and until the phone lines are back in service," the statement read.

The Canadian Pharmacy giant shut all its stores across Western Canada on Sunday after it was discovered that it was the victim of a cybersecurity incident on April 28.

"Upon discovering the incident, London Drugs immediately undertook countermeasures to protect its network and data, including retaining leading third-party cybersecurity experts to assist with containment, remediation and to conduct a forensic investigation," a written statement to DiscoverAirdrie stated.

"At this time, we have no reason to believe that customer or employee data has been impacted. Pharmacists continue to stand by to support any customers with urgent pharmacy needs."
