Doors Open Markham

Doors Open Markham is back! Guests are invited to explore a variety of buildings throughout the City as they open their doors – for one day only – to visitors. Doors Open Markham provides a behind-the-scenes look at select buildings throughout Markham and free access to buildings that usually charge an admission fee. Markham is home to many cultural, heritage, and innovative buildings; providing guests the opportunity to explore the stories and inspiration that helped to make Markham what it is today.

The City is proud to once again host this free event.
