Although the Montreal metro system is ranked one of the best in the world, locals know that it experiences problems on the daily.\nFrom floods to hour-long delays, our beloved metro has seen it all.\nRead about some of the Montreal metro's worst service interruptions since 2007 below!\nVisit MTLBlog for more headlines.\nMetro service interruptions in Montreal are all-too-common and for the most part, we take them in stride. Usually, a metro delay only lasts a few minutes and despite the annoyance, it's a fact of life. Montreal's metro system is one of the most efficient in the world but try saying that to any local and they'll roll their eyes and laugh. Trust me, it's true!\nOur metro is iconic for not only its stunning architecture and questionable etiquette, but also for how it divides our city. On one hand, you have advocates who champion its effectiveness and on the other, people who wouldn't be caught dead riding the rails. And everyone hates when the metro gets delayed pretty much every single day.\nIn many cases, we only have ourselves, as humans, to blame for causing metro delays. A month-to-month study conducted by the STM shows that over 50% of metro delays are caused by riders.\nWhile you experience them (almost) every day, let's take a trip down memory lane and check out some of the worst metro service interruptions since 2007!\n2019: A Pepper-Spray Incident Shut Down 3 Metro Lines, Downtown Bus Routes, And Sent Two People To Hospital\nC’est le chaos à Beaubien ... j’ai jamais vu ça en 20 ans à Montréal. #polmtlLe reste de ma route se fera donc à pieds ... pic.twitter.com/53XQvw6wK5— Carl Charest (@carlcharest) January 9, 2019\nIn what can only be described as a series of unfortunate events, a discharge of pepper-spray shut down three metro lines and a number of downtown bus routes this January.\nThough the delay only lasted under two hours, the STM was heavily criticized for their response to the situation.\nREAD ALSO: Orange Line Shutdown Extended As Locals Rename Flooded Station "Chutes De Square Victoria"\n2007: Two Cracks In The Tunnel Running The Length Of A City Block Shuts Down The Green Line For A Whole Weekend\nView this post on Instagram Station Verdun 🚇 #stminfo #stm #mtlmetro #metrostation #mtlunderground #stationverdun #metromtl #subwaystation A post shared by STM Mouvement collectif (@stminfo) on Oct 1, 2018 at 3:30pm PDT\nBack in 2007, workers found two huge fissures inside downtown metro tunnels. The cracks were so large that firefighters had to evacuate downtown office buildings and parts of the Underground City.\nDue to safety concerns, the STM and city officials closed the Green Line between Lionel-Groulx and Berri-UQAM for a whole weekend.\n2019: 2 Metro Car Tires Explode, Shutting Down The Orange Line For 4 Hours During Rush Hour\nI guess you won't really know if you're claustrophobic unless you take the Montréal metro today #stminfo #STM pic.twitter.com/yHsU1IJxPi— Sinclair (@SinclairLore) January 9, 2019\nThe Orange Line between Berri and Henri Bourassa was closed for four hours this past April after two tires on the new AZUR Metro cars exploded. Workers had to physically tow away the broken metro.\nAs is tradition, the delay was during peak rush hour from 1 p.m. to 5 p.m.\n2012: Protestors Detonate Three Smoke Bombs That Shut Down The Metro During Morning Rush Hour\nSmoke bomb explodes today in the morning in the metro station in montreal pic.twitter.com/aeJk4wLn— Mendy Sternfeld (@MendySternfeld) May 11, 2012\nDuring the student protests of 2012, four protestors coordinated a series of smoke bomb detonations during the early morning rush hour at three incredibly busy stations. Thousands were evacuated and the delay lasted from 7 a.m. to 11 a.m. — so we can guess that many people were late to work that day.\nThe mayor at the time was understandably pissed and initiated a city-wide manhunt to find the four protestors.\n2019: A Water Main Bursts, Shutting Down The Orange Line During Morning Rush Hour & Floods Square-Victoria Station\nNot good. pic.twitter.com/r6LbgSOCCq— Jay Turnbull (@TurnbullJay) November 14, 2019\nMuch has been written about the flood incident on November 14, so here's a couple of videos that show the extent of what happened at Square-Victoria OACI.\nVIDÉO | SUIVI : Infiltration d’eau STM station Square-Victoria—OACI. pic.twitter.com/KbkCiSC4Do— Simon-Marc Charron (@SMCharronRC) November 14, 2019\nAt around 6:30 a.m., workers found that water had infiltrated the metro system because a water main had burst. Because of this, the entire Orange Line between Lionel-Groulx and Berri-UQAM was shut down for roughly six hours.\nDuring rush hour, of course.\nNeedless to say, metro delays are a fact of life in Montreal.
