The Management of Abandoned Aggregate Properties (MAAP) Program is responsible on behalf of the Trust for the identification and rehabilitation of pits and quarries that were abandoned prior to January 1, 1990. The MAAP program is fully funded by a portion of the annual fees paid by the aggregate industry (½ cent per tonne). Based on recent levels of production in Ontario this formula provides approximately $700,000 towards rehabilitation and research. This has allowed the program to rehabilitate approximately 15-20 abandoned aggregate sites every year and to support several research initiatives.

From 1990-1997, the program (then known as the Abandoned Pit and Quarry Rehabilitation Fund) was administered through the district offices of the Ministry of Natural Resources. In 1997 the program was transferred to the Aggregate Resources Trust and renamed the MAAP Program. The Aggregate Producers’ Association of Ontario administers MAAP on behalf of the Trust by way of an agreement with the Trustee, The Ontario Aggregate Resources Corporation.

To date, over 200 hectares of land have been rehabilitated through MAAP and its predecessor. Over $2.5 million has been spent to make abandoned aggregate sites safer, more productive and aesthetically appealing. The majority of sites were rehabilitated to natural areas, while others were transformed into productive agricultural land and recreational space. Over the years, MAAP has partnered with private landowners, conservation authorities, municipalities and local recreational clubs to help turn abandoned sites into thriving spaces.

In addition, MAAP has funded several research initiatives including a study that investigates the degree of naturalization and biological diversity that has developed over time in abandoned aggregate sites on the Oak Ridges Moraine and a study undertaken in partnership with Fisheries and Oceans Canada that investigates the affect habitat manipulation has on fish populations in abandoned aggregate ponds.
