Every April to October, Ontario’s heritage treasures are open 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 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.
Doors Open Ontario 2020 encompasses 34 events including more than 900 built and natural heritage sites across the province. At each event, local programmers will share unique and interesting Ontario stories, take Ontarians behind-the-scenes of stunning heritage sites and provide one endless adventure to Ontarians from across the province.
