This weekend, Toronto faces significant transit disruptions due to severe winter weather and scheduled maintenance. The TTC has temporarily closed part of Line 1 between St. George and Osgoode stations from 11 p.m. Friday to Sunday, with no shuttle buses available, affecting key stations including Museum, Queen’s Park, St. Patrick, and Osgoode. The closure was initially planned until Sunday but was shortened due to the storm, and service resumed around 10:30 a.m. on Sunday after a track injury investigation at Union Station caused temporary delays on streetcar routes. Meanwhile, GO Transit will suspend train service between Oakville and Mimico stations on Saturday and Sunday for bridge replacement work, with buses replacing trains at certain stations and special hourly trains running between Mimico and Union stations. The city is also under a winter storm warning with snowfall expected to reach 15-30 cm, and extremely cold temperatures are forecasted for the weekend, prompting advisories to stay indoors. These disruptions come amid ongoing weather alerts and other city news, including political comments from U.S. President Donald Trump and police investigations into local incidents.
