The $27 billion Ontario Line subway is a monumental step forward for Toronto public transit, and the mega-project is already making significant headway at various points around town. Metrolinx has issued construction notices announcing the start of early works at the sites of Flemingdon Park and Thorncliffe Park stations. The transit agency shared via community notice that "site preparation work is underway at 770 Don Mills Road to get ready for Ontario Line construction." Based on this timeline, it is safe to assume that actual construction mobilization will follow as early as November. The terminal Don Valley Station (formerly Science Centre) to the north at Don Mills and Eglinton will also follow this elevated configuration.
