GPA members were engaged as the lead consultant for this study. The objectives were to: 1) identify the consequences of continued growth in the Toronto Region according to past land consumption patterns; 2) develop a model to estimate CO2 emissions and other transportation impacts of alternative urban forms: 3) examine the opportunities for infrastructure investment in the region based on alternative watershed management practices; 4) identify a preferred alternative structure for development of the Toronto Region; and 5) prepare a set of governance, planning and fiscal strategies for achieving the alternative structure. The study involved an extensive analysis of land consumption patterns using aerial mapping and GIS technology and combining this with census data. This study set the stage for the subsequent development of an overall growth management plan for the Toronto Region.
