Montreal Airport outage in March sparks class action lawsuit — Here's how to get paid

If you were caught in the chaos at Montreal-Trudeau Airport on March 25, you might be entitled to compensation. A class action lawsuit has been filed in Quebec following the major system failure that disrupted operations and stranded thousands of travellers.

The case is being led by LPC Avocats, who say anyone who was at the airport that day — whether flying, working, or even just tagging along with someone — could be eligible to join.

What happened at YUL?

The chaos started in the early hours of March 25, when Bell Canada carried out a scheduled update to Aéroports de Montréal’s IT infrastructure. Despite passing tests in a lab setting, the update triggered a widespread failure across the airport's systems — from check-in counters to passenger services.

The result? A total breakdown in operations that lasted nearly 24 hours. Montreal-Trudeau confirmed on social media that passenger processing was severely affected throughout the day, especially at check-in.

According to LPC, travellers were met with handwritten flight boards, overwhelmed staff, and long, slow-moving lines.

Why the lawsuit?

According to LPC Avocats, those who were at the airport that day experienced more than just a delay. Many lost access to essential services, missed work or connecting flights, and dealt with significant stress, all of which the legal team says should be compensated.

The lawsuit aims to recover costs like lost wages, travel expenses, and time wasted due to the outage.

Who can participate?

If you were physically at Montreal-Trudeau Airport on March 25, 2025 — whether as a passenger, employee, or even someone accompanying a traveller — you may be eligible to join the class action.

The case still needs to be approved by the Quebec Superior Court before it can officially proceed. In the meantime, LPC Avocats is inviting anyone affected to register by filling in a form on their website.
