Architectural Conservancy Ontario - London Region
The London Region branch of the Architectural Conservancy Ontario (ACO) is a volunteer-driven advocacy organization founded over 50 years ago with the threatened destruction of London’s original financial buildings, the Ridout Street Complex, now a National Historic Site.
ACO London is committed to conserving London’s heritage architecture through public awareness and advocacy. We support and encourage architectural conservation through reuse and repurposing of older buildings, the creation of Heritage Conservation Districts to protect our historic neighbourhoods, and the active retention and maintenance of London’s unique history as embodied by its built heritage.
