The Regional Municipality of York has completed an Environmental Assessment (EA) Study for improvements to Dufferin Street between Langstaff Road and Teston Road in the City of Vaughan.

  • Widen to six lanes from Langstaff Road to Marc Santi Boulevard, located north of Rutherford Road
  • Widen to four lanes from Marc Santi Boulevard to Teston Road
  • Construct cycling facilities and sidewalks on both sides of Dufferin Street
