Ordinary People, Extraordinary History
If you ever stopped to look at a building whose architectural features or sense of history held your interest, ACO might just be what you are looking for.
Most people who join ACO are not architects, they are citizens who want to know more about our built heritage and how we can work together to save the best of it.
For over eighty years, ACO has been working to find viable uses for Ontario’s historical assets ensuring that the distinctive buildings of our past do not become parking lots or building sites for characterless new development.
You can support our ongoing advocacy by making a donation, by volunteering on one of our many committees, by purchasing a historical house sign, or by becoming a member.

Province-wide but with local impact, Architectural Conservancy Ontario (ACO) is committed to conserving Ontario's architectural heritage and cultural heritage landscapes through advocacy and direct action. Founded in 1933 by renowned Toronto architect Eric Arthur, ACO was established to help conserve Ontario’s architecturally-significant structures – not just those of the 18th and 19th centuries, but more modern ones as well – saving them for future generations.
Our work is focused on encouraging the adaptive re-use of heritage buildings, helping local communities save beloved structures from demolition, honouring the work of architectural conservationists and supporting young professionals in the field. ACO operates through a network of 25 local branches in communities across Ontario, linked by a co-ordinating office in Toronto, and governed by its Board of Directors and Provincial Council.
You can donate right now via the Provincial ACO office or by clicking the button below. If you would like to make ACO part of your legacy gifting, please contact our branch president, Wes Kinghorn.
Join ACO London
Joining ACO London is a great way to meet all sorts of people who want to help preserve the architectural heritage in our region, people who value our built heritage, who want to conserve those features that make London a distinctive city, who believe that heritage is one key way a community maintains its identity and who believe that adaptive re-use is a green option.
Joining ACO through the London Region branch puts you in touch not only with London events but with activities across the province. As a member of ACO London you will receive its tri-annual newsletter, the ACORN, and the London Region newsletter, The Advocate.
With the public attention recently on several significant heritage buildings, threatened to be destroyed, it is vital that ACO be strong enough to present a defence of our built heritage. Your financial support will help us achieve this.
