Come and explore the Ontario Heritage Trust’s popular Doors Open Ontario program and learn more about the province’s spectacular heritage sites!

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 a typical year as they learned about heritage conservation, local history and had fun.

Starting in 2020, the Doors Open Ontario program has also included digital experiences to engage visitors. While we await the return to in-person events, you can still visit sites digitally and enjoy online experiences that you might not be able to have in any other way.

The Ontario Heritage Trust still 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. But with Digital Doors Open, there is more to explore.

The in-person program will continue to run from April to October each year, but the Digital Doors Open program will now run year-round. And be sure to check out our sample staytrip itineraries, too, to travel across the province – virtually – in the span of a single day.
