Now in its 85th year, ACO exists because of its supporters, most of whom are individuals living across Ontario who care deeply about our built and cultural heritage. Our members pay a small annual membership fee which entitles them to receive our signature publication, ACORN Magazine, and regular communications from our provincial and branch offices. Many also choose to make annual or monthly gifts to support our work in heritage conservation, education, and advocacy. These individuals are increasingly joined by companies who want to invest in the future of Ontario’s heritage buildings.
