Doors Open London - celebrating it's 25 years on Saturday, September 19 and Sunday, September 20, 2026, London Ontario.
This year's Doors Open London is themed "Cheers to Years: Celebrating 25 Years Together."
For a quarter century, Doors Open London has connected residents and visitors with the places, people and moments that shape our city. In 2026, participating sites and organizations are encouraged to reflect on their journeys, highlighting how they’ve grown, adapted and contributed to London’s evolving identity. Be part of a weekend full of engaging experiences, including live performances, interactive demonstrations, guided tours and historical re-enactments. From the transformation of local industries to the repurposing of beloved heritage buildings, this anniversary year will shine a light on how London has continually adapted to meet the needs of its people.
