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.
Since the program was launched in 2002, over 8.3 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 $11 million during their travels in 2019 as they learned about heritage conservation, local history and had fun.
