Earlier this year, the ACO published a book to celebrate its 80th anniversary. “80 for 80: Celebrating Eighty Years of the Architectural Conservancy of Ontario” contains 80 properties that the ACO has had a hand in saving over the past 80 years. The book contains beautiful, full page photos of each building. The stories included detail the creative ways that ACO’s branches and volunteers have found to challenge unsympathetic development and to rescue buildings at risk.
