Saturday, September 30, 2017 | 10 a.m. - 4 p.m.

Markham celebrates Canada 150! This year’s FREE Doors Open Markham event marks this significant milestone in our nation’s history. Our sites include historical places that reflect our community’s past as well as sites and programs that represent the diverse cultures that contribute to the City of Markham of today.

The City of Markham is a place where the old and the new co-exist as a unique expression of our community. With our blossoming downtown Markham Centre taking shape only a short distance away from historic Unionville, we are a city of contrasts and diversity that reflects our civic motto, Leading while remembering.
