A motorcyclist is in hospital with serious injuries after an early morning hit-and-run crash on Toronto’s Gardiner Expressway. Police say officers responded to the collision near the Gardiner Expressway West and Spadina Avenue just before 5 a.m. Paramedics tell CP24 they transported a 35-year-old woman in “serious but stable condition.” Police said the driver and vehicle involved failed to remain at the scene. As a result, three left lanes of the westbound Gardiner Expressway are closed while the investigation continues. Drivers are being asked to “consider alternate routes.”
