Doors Open Ontario is back! 13 weekends, 22 events and hundreds of places to visit for free in 2023

TORONTO — Starting April 29 in Guelph, hundreds of places across the province will open their doors free of charge as part of Doors Open Ontario, an annual program of the Ontario Heritage Trust. The 2023 season will be held over 13 weekends and features 22 in-person events running from April to October. Ontarians can visit the province’s most fascinating places and discover exciting architectural, cultural and natural heritage experiences. Details are now available at with new listings being added each month.

Every year, visitors to Doors Open events gain rare access to buildings and spaces that are normally closed to the public or sites that normally charge admission. The events have something for everyone — in addition to free access, many sites are also hosting walking tours, interactive experiences, special exhibitions and more.

This year, the Trust is exploring Ontario’s food culture and history. From breweries to farms, Doors Open events will also include sites or special programs to highlight our culinary or agricultural heritage.

“Discovery is at the heart of Doors Open Ontario,” said John Ecker, Chair, Board of Directors, Ontario Heritage Trust. “We encourage everybody to make a trip to one or more of the 22 Doors Open events happening this year. You’ll uncover new stories, connect with people and see outstanding places that showcase how these vibrant communities help to create that sense of belonging that brings us all together.”

Digital Doors Open Ontario also returns with hundreds of listings available online. These virtual experiences can help you fill a rainy afternoon, plan a staycation or virtually visit impressive destinations across the province that may be too far away.
