TORONTO, April 16, 2026 /CNW/ - The Ontario Heritage Trust is celebrating the 25th season of Doors Open Ontario in 2026, marking a milestone for one of the province's most successful and widely participated heritage programs. With more than 9.5 million visits since 2002, Doors Open Ontario has become a defining shared public experience of heritage across the province.
Held on select weekends from April to October, this annual series of events offers free, behind-the-scenes access to historical, cultural and natural heritage sites -- many of which are normally closed to the public. Over the last quarter century, the program has transformed places that Ontarians once passed by into spaces they can explore firsthand, helping to build understanding, pride and long-term support for heritage conservation.
Led by the Ontario Heritage Trust, sponsored by the TD Ready Commitment and brought to life by local organizers and communities, Doors Open Ontario has grown into the only provincewide heritage open-house program of its kind in Canada. This program brings local heritage properties into a festival of discovery that unites big cities and small towns in a shared purpose: welcoming hundreds of thousands of curious people annually.
Since its launch in 2002 with 17 events and 289,000 visits, Doors Open Ontario has grown into one of the province's most recognizable cultural events. Last year, the program featured 32 events and welcomed 461,000 visits -- underscoring the public's enduring appetite for access to meaningful places and experiences that tell the story of Ontario.
The 2026 season kicks off with Doors Open Stratford on April 18 and wraps up with Doors Open Niagara Falls on October 18. It will include events in 34 communities across the province. Special 25th season spotlights, stories and features will roll out throughout the year on Trust channels. Ready to plan?

"For 25 years Doors Open Ontario has helped people experience the places that shape their communities -- up close, free of charge and with a sense of shared discovery," said John Ecker, Chair of the Board of Directors of the Ontario Heritage Trust. "We're proud of the role the Trust has played in supporting this program at a provincewide scale, alongside the organizers, volunteers, funders and partners who bring these events to life."
"Doors Open Ontario is a unique opportunity that connects communities with the places and stories that shape Ontario. I want to congratulate the Ontario Heritage Trust on the program's 25th anniversary and thank them for opening doors to explore the rich and diverse heritage that defines our province. This year, I encourage everyone to participate by visiting these sites and learning about the incredible stories found in our own backyards." -- Graham McGregor, Minister of Citizenship and Multiculturalism
