Doors Open Markham offers an insider’s look into many historic and contemporary buildings. Since 2013, Doors Open Markham has brought thousands of people together from inside and outside Markham to our community’s signature heritage city-wide event!
Doors Open Markham features locations that are often not open to the public and offers you the opportunity to explore Markham’s unique and sometimes hidden architectural treasures.
Organized under the direction of a Council-appointed committee made up of City staff, municipal councilors, and community volunteers, this event is one of a series of events held across the province under the organizational umbrella of the Ontario Heritage Trust – Doors Open Ontario.
