As a looming New Year's storm threatens to force flight cancellations at Montréal-Pierre Elliott Trudeau International Airport, maintenance workers are threatening to strike if their union can't reach a contract agreement with their employer.\nThe strike could begin as soon as New Year's Eve.\nVisit MTLBlog for more headlines.\nLet's hope you're already home from any holiday vacations or aren't planning on taking off on a trip as the new year hits, because the Montréal-Pierre Elliott Trudeau International Airport is going to be a bit of a mess as 2019 comes to an end. Not only is a huge snowstorm headed Montreal's way, already threatening the cancellation of flights, but airport workers have officially given notice of a strike that could begin as soon as December 31, 2019.\nAccording to the Montreal Gazette, a 72-hour strike notice was given to Swissport Canada this past Saturday on behalf of the International Association of Machinists and Aerospace Workers (IAMAW) who intend to strike this week if a deal is not reached.\nSwissport supplies all the fuel for both Montreal airports, the Montréal-Pierre Elliott Trudeau International Airport in Dorval (YUL) and the Montréal–Mirabel International Airport, in Mirabel (YMX).\nWorkers responsible for refuelling, as well as machinists, mechanics, dispatchers, and maintenance staff, have all been "without a contract since last August," the Gazette explains, as negotiations over salaries and work-life balance continue between the union and Swissport.\nWe reached out to the IAMAW for a statement about the looming strike but they did not respond to our request for comment.\nAccording to The Canadian Press, IAMAW union members "have voted 99 percent in favour of a strike," which would begin at an as-of-yet unspecified time on December 31, 2019.\nMontreal airport refuellers vote in favour of New Year’s Day strike:https://t.co/URvf1yJvyS#Aviation #Airport pic.twitter.com/L9mOurXVji— SpeedBird (@SpeedBird_NCL) December 30, 2019\nA press release issued by Swissport explains the company is "surprised and disappointed" by the IAMAW's rejection of a tentative agreement offered this past weekend.\nThey also insist that "travellers, customers, stakeholders and airport authorities can rest assured" that Swissport is dedicating "every effort to reach an agreement and continue the refuelling service during this busy period."\nREAD ALSO: Up To 25cm Of Snow Is About To Get Dumped On Montreal For New Year's Eve\nWithout staff to refuel airplanes, it is unclear how air traffic could continue as normal, particularly as Swissport Canada is the only supplier of fuel for planes coming in and out of both Trudeau and Mirabel airports.\nThen, of course, we have a storm looming, as well.\n“Let It Sleet” :-) #mtl #montreal #sleet #winter #weather #urbanphotography @meteomedia @weathernetwork pic.twitter.com/D1N66yVy1R— Daniel Béland (@danielbeland) December 30, 2019\nEnvironment Canada issued a snowfall warning for the Montreal area, along with several other regions in Southern Quebec early this morning.\nSnow is expected to start falling in Montreal this afternoon and continue through the evening, overnight and well into Tuesday.\nThis could mean significant delays for flights coming in and out of both Montreal airports.\nthe montreal airport has been closed and there was a flight supposed to board,, f for them— math new pinned!!
