In February 1997 the Ontario Ministry of Municipal Affairs (MMA) revised the aircraft policy to prohibit residential development above NEF/NEP 30. The previous threshold was NEF/NEP 35. In order to satisfy the development industry the MMA permitted any development that was already draft approved to proceed under the old policy. However, the Greater Toronto Airport Authority (GTAA) appealed these plans to the Ontario Municipal Board (OMB). In order to ensure that the GTAA withdrew its objection at the OMB an agreement between the GTAA and the developers was formulated. Each developer of the residential lands was required to enter into a binding agreement with the GTAA and the City of Mississauga that stipulated very specific conditions. These conditions are summarized below. Further the City of Mississauga, the municipality in which the Toronto International Airport is located, required that all the conditions be strictly followed. The importance of this is discussed in subsequent sections.
