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 hiding inside.

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.
The Doors Open Ontario website makes it easy for you to discover events happening across the province and identify which of the interesting buildings and sites you would like to visit. Please explore the website and the many features that will help you organize a successful Doors Open Ontario outing.

Since the program was launched in 2002, over seven million visits have been made to thousands of unique buildings and spaces, creating new stories with each visit. The Doors Open Ontario program also has a big impact on local communities, as participants spend around $5 million annually during their travels, as they learn about heritage conservation and local history, and have fun.

Join the millions of visitors who have had a great Doors Open Ontario experience, and start planning your excursion today.
