For at least the fourth day in a row, Toronto's extreme cold is wreaking havoc on the city and it's really in your best interest not to leave your house today. Not only are the temperatures themselves terrible - it currently feels like -33°C out there - but the weather is having a major impact on anyone trying to get around the city. On top of that, these temperatures are considered a health hazard.\nGiven the frighteningly low temperatures, Environment Canada still has an extreme cold warning in place for Toronto and most of Southern Ontario. In their warning, they highlight the dangers of the cold saying that in these temperatures frostbite can develop in minutes. The greatest risks of cold-related symptoms are for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter.\nEven if you don't fall in one of those categories, today is still a terrible day to try to get around Toronto. Another reason for that is black ice that is coating some roads and highways. While they didn't provide an exact number the OPP confirmed this morning that because of the ice there have been crashes all over the GTA.\nThen, on top of all that, there's the TTC, which Torontonians already know doesn't fare very well when it's cold outside.\nYet again this morning riders were met with crazy delays throughout the TTC system. For instance, Line 3 of the subway is still completely shut down and Line 1 and 2 have both been experience major, on-going delays due to signal issues, which are caused by the cold.\nWhile people aren't surprised by the delays anymore, they are still expressing their feelings about it on Twitter.\nThe #ttc is in shambles! Utter #disaster with their constant delays @TTChelps @TTCnotices\n— Cameron Rodrigues (@RodriguesCam21) January 31, 2019\nAnother day, another delay #ttc #topoli #itsbeyondfrustrating @TTChelps @JohnTory\n— Rakesh Gopinath (@rakeshgopinath) January 31, 2019\nIt’s now been 25 minutes standing on the platform at Spadina.Not a single announcement about a delay. Platform is rammed. #TTC #TOpoli\n— Mike Beauvais (@MikeBeauvais) January 31, 2019\nSeriously, @TTChelps, @JohnTory, @fordnation - fix public transit NOW. The fact that major delays have happened every single day of 2019 so far because of the cold is unacceptable. #TTC #FrustratedCommuter\n— Tawnya (@frugalistamom) January 31, 2019\nREAD ALSO: There's A New Presto App That Lets You Automatically Re-Load Your Card From Your Phone\nIt's not just the TTC either, the GO trains are also been affected by the extreme cold and it has created incredibly long delays on some lines.\nI spend almost $400 a month to use the @GOtransit & TTC. But if the service is not operating as it should, what I pay doesn’t change. Currently on hour two of what is usually a one hour commute because of service delays on both systems @Metrolinx @TTChelps\n— nam kiwanuka (@namshine) January 31, 2019\n@GOtransitKT @GOtransit @CTVNews I hope this “Express” Kitchener train to union makes it to Union in time to get my train home tonight. 97 minute delay and counting.\n— BRiDGeT McDeRMiD (@BRiDGeTMCDeRMiD) January 31, 2019\n@GOtransitKT @GOtransit, you need to do better. How do you explain a 2hrs delay???\n— Janvière (@i_zanvil) January 31, 2019\nREAD ALSO: Southern Ontario Is In For Even More Deep Freezes And They're Expected To Last Until The Middle Of March\nTo sum it all up, Toronto is completely frozen over to the point of almost not functioning and if you can avoid going outside today you definitely should do that.
