This is the list of disruptions in Toronto due to the global IT outage

A global technology outage impacting businesses around the world has led to major disruptions in the GTA and other parts of Ontario. Cybersecurity firm CrowdStrike said the issue is affecting Microsoft 365 apps and services.

Here is a look at how GTA residents are impacted:

Transportation

Air travel

Porter Airlines had cancelled all flights until 3 p.m. and Pearson International Airport says U.S. airlines, including America, United, and Delta, are reporting issues. Canadian airlines, including Westjet, Air Canada, Flair, and Sunwing are operating as usual, the Greater Toronto Airports Authority (GTAA) confirmed to CP24.

At around 2:30 p.m., in an update on its website, Porter Airlines says, “Operations are in the early stages of returning to normal.”

Porter notes that its website will be restored when all its systems are online. Once that happens, passengers can check their flight status and access their reservations.

“Passenger communications are also being processed to advise of updated flight bookings for those who experienced earlier cancellations,” Porter says, adding that it will take a period of time with new flights confirmed over several days due to high passenger volume.

The update did not say if flights scheduled after 3 p.m. will proceed.

Transit

The TTC says service is not impacted by the outage and systems have not been affected. Metrolinx says while trains and buses are operating as scheduled today, customers may have difficulty accessing their PRESTO accounts online and through the mobile app. PRESTO cards can be topped up at GO stations, the provincial transit agency said.

Land border crossings

Police in Windsor reported long delays at both the Detroit-Windsor Tunnel and the Ambassador Bridge due to the worldwide outage.

Hospitals

University Health Network, North York General Hospital, and Sunnybrook Health Sciences Centre are reporting that systems have been impacted by the CrowdStrike outage. Clinical activity is continuing as scheduled but hospitals are warning of delays.

Universities and Colleges

Durham College says some of its systems have been impacted by the outage but noted that the school is open and classes are operating as scheduled today.

Municipalities

The City of Toronto says some services may be "experiencing technical difficulties" due to a global software issue. "Emergency services are operating as normal," the city confirmed.
