While we endeavour to keep the list of Ward 1 development applications up-to-date, things can change frequently.
We encourage you to also visit “MappiT” the City of Markham’s Development Application Viewer.
Members of the public can search various development applications city-wide as well as tree removal permits to check on their status.
