This area, referred to as the Toronto Brickyard, was designated as an earth science Area of Natural and Scientific Interest (ANSI) by the Ontario Ministry of Natural Resources in 2009 for exhibiting "Ordovician Georgian Bay Formation, Illinoian Glacial York Till, Sangamonian Interglacial Don Formation and Wisconsian Glacial Scarborough delta, Pottery Road sediments and Sunnybrook Till all overlain by North Bay Interstadial, Lake Iroquois sands." Evergreen, a Canadian non-profit organization whose activities have included stewardship of the Don Valley Brick Works buildings site since 1991, has transformed the abandoned buildings into a cultural centre with a focus on the environment. Having leased the "industrial pad" portion of the site from the Toronto Region and Conservation Authority, Evergreen has renovated several of the existing structures and constructed one new building known as the Centre for Green Cities. The goal of the revitalization is adaptive reuse, where most of the buildings will be reinforced where needed and repurposed to house the new programming planned for the site. In this way, the site can be recycled as much as possible and the historical integrity of the Don Valley Brick Works can be maintained. Evergreen Brick Works will be an education centre addressing the themes of nature, culture and community. [I]t will be a destination for families and individuals to enjoy a natural refuge, while sampling a rich offering of programs and services - from gardening workshops, heritage tours, and clay-making and organic food markets, to a retail nursery, demonstration gardens and leading-edge green design techniques.   $20 million of the project's $55-million dollar budget was pledged by the federal government under the Canada Strategic Infrastructure Fund, and the Province of Ontario contributed an additional $10 million. The construction process began in November 2008, and grand opening of Evergreen Brick Works took place September 28, 2010. The complex is now open to the public, with regular shuttle bus service running daily from Broadview Subway Station. Public transit is also available on Saturdays from Davisville subway station by bus route 28A Davisville. Design and construction was a joint venture between Du Toit Allsopp Hiller Architects, Diamond and Schmitt Architects, and several other prominent firms. DTAH is responsible for the master planning, while Diamond and Schmitt are the designers of the new building, which includes the Young Welcome Centre. Other programming for the site includes art exhibits, children's programming, garden centre, and office space for Evergreen and other environmental organizations. Restoration to the building include structural reinforcement, and replacement of material such as the current asbestos transite roofing in favour of a more effective, longer lasting material.
