What secrets are behind Brockville’s historic buildings? On Friday, September 18, 2026, from 10 a. m. to 4 p. m., Doors Open Thousand Islands invites you inside 16 local spots with histories dating back over a century.
You can take a look at Fulford Place-a grand Edwardian mansion built between 1899 and 1901 by Senator George T. Fulford-who made his money selling “Pink Pills for Pale People.” Brockville City Hall, which opened in 1864, holds another surprise: it stands right above the historic Brockville Railway Tunnel-the first railway tunnel in Canada.
A few other places include the Brockville Arts Centre (once town hall and marketplace dating back to 1858) and the Brockville Museum located in the circa-1815 Isaac Beecher House. You can even see an 1895 building now occupied by the 1000 Islands Brewing Company. The history here is full of unexpected twists.
London – September 19 & 20
If you could spend one weekend visiting everything from a cemetery that’s been around for over two centuries to the home of a medical pioneer? Doors Open London is back on Sept. 19 and 20, 2026, featuring 40 sites with its anniversary theme: “Cheers to Years: Celebrating 25 Years Together.”
You can step inside Banting House-tied to Sir Frederick Banting since it was built in1907-explore Eldon House (London’s oldest house from1834), or stroll through Brick Street Cemetery where graves date back to1813 including early settlers and War of1812 veterans.
The Fanshawe Pioneer Village brings life from1820 to1920 alive through costumed interpreters across its30 heritage buildings. Military history also shines at the1st Hussars Museum plus an original1942 building from London Airport’s wartime training base.
