May in Ontario marks the return of one of the province’s most cherished cultural experiences: Doors Open Ontario. Organized by the Ontario Heritage Trust, this initiative allows residents and visitors to explore some of the region’s most fascinating buildings, heritage sites, and cultural landmarks—many of which are not usually open to the public.

Throughout the month of May, towns and cities across Ontario host their own versions of Doors Open, each showcasing unique local treasures. From historic churches and opera houses to restored railway stations and modern architectural gems, the program invites participants to go behind the scenes and engage with history in a hands-on way.

One of the standout features of the event is the diversity of sites available. Whether you're an architecture buff, a history enthusiast, or someone simply curious about your community’s heritage, there's something for everyone. The events are free to attend, making them an ideal weekend outing for families, couples, or solo explorers.

In addition to physical site visits, some communities offer virtual tours and interactive programming for those who prefer a digital experience. The Ontario Heritage Trust also collaborates with local historians, artists, and cultural groups to enrich the storytelling behind each location.

Doors Open is more than just a tour—it’s a celebration of the people and places that have shaped Ontario. It's also an important reminder of the value of preservation, community memory, and accessible culture.
