Doors Open Ontario


The Ontario Heritage Trust works with communities across the province to open the doors, gates and courtyards of their unique and most fascinating cultural sites so you can explore the stories inside.

Every April to October, many of Ontario’s heritage treasures are opened to the public with free events across the province. Whether you are exploring on your own, organizing an outing with family and friends, or planning a first date, Doors Open Ontario has something for everyone.

From historical houses to modern marvels of construction, Doors Open Ontario showcases the buildings, natural spaces, infrastructure and cultural landscapes that shape and define our communities.

In 2018, Ontario commemorates 100 years since women’s suffrage and the equality movement in Ontario’s pluralistic society. As the Trust explores the province’s efforts to move "toward a fair and just society," Doors Open Ontario will provide an opportunity to visit some of the buildings and sites associated with this movement. Possible related sites could include: meeting halls, churches, government buildings, homes of women who were central to this struggle, union buildings and other public spaces that hosted important events in the struggle for women’s rights.

Since the program was launched in 2002, over 7.3 seven million visits  have been made to thousands of unique buildings and spaces. The Doors Open Ontario program also has a big impact on local communities, with participants spending more than $13.1 million  during their travels in 2017 as they learned about heritage conservation, local history and had fun.
