Niagara Falls residents can explore 13 local heritage and community sites without an admission charge during Doors Open Niagara Falls on Sunday, Oct. 18, 2026. The event runs from 11 a.m. to 5 p.m., according to a City of Niagara Falls media release.
Participating locations include historic churches, a War of 1812 battlefield, museums, cultural spaces and buildings being put to new uses. Some sites will offer guided tours, demonstrations and opportunities to meet the people responsible for their care.
The City of Niagara Falls Municipal Heritage Committee is organizing the one-day event as part of Doors Open Ontario, a province-wide program. Both residents and visitors are welcome to take part.
Registration needed for water treatment plant tours
One participating location has specific requirements visitors will need to arrange ahead of time: the Niagara Falls (Chippawa) Water Treatment Plant.
Plant tours require advance registration, and drop-in visitors cannot be accommodated. To register, participants must email wwwtours@niagararegion.ca.
Anyone taking a water treatment plant tour must wear closed-toe shoes and long pants.
Although admission is free at all participating sites, the city advises visitors to check each location’s listing before setting out. Those listings contain individual hours, accessibility details, activities and any tour requirements.
Planning a heritage weekend
The full list of Niagara Falls locations and their descriptions is available through Doors Open Ontario at doorsopenontario.on.ca/pages/events/niagara-falls. Visitors can use the listings to plan which sites to visit during the event.
There is also a neighbouring event the day before: Doors Open Niagara-on-the-Lake takes place on Saturday, Oct. 17, 2026. The two events offer an opportunity to explore local heritage over the same weekend.
The Niagara Falls event focuses on the city’s history, architecture and community life. David Servos UE, chair of Doors Open Niagara Falls, said in the release that the event aims to connect residents and visitors with the community’s past and encourage appreciation and protection of its cultural heritage.
