Planning for Prosperity: Globalization, Competitiveness, and the Growth Plan for the Greater Golden Horseshoe was released by the Neptis Foundation in late 2015. It was intended to contribute to the Province of Ontario's Coordinated Review of the Growth Plan for the Greater Golden Horseshoe, the Greenbelt Plan, the Oak Ridges Moraine Plan, and the Niagara Escarpment Plan in 2016. The Neptis report described the economy of the Greater Golden Horseshoe and the region's changing economic landscape, identifying important considerations for the Growth Plan.
Among other things, Planning for Prosperity identified three major suburban regional employment "megazones." These are large, economically significant employment areas that had not been recognized in nor addressed by the Growth Plan. Given the importance of these megazones to the regional, provincial, and national economies, as well as their role in achieving key Growth Plan objectives, Neptis sponsored further research on these areas to inform planning and policy development. This policy brief provides additional detail on the Tor-York East megazone. Companion policy briefs provide similar profiles of the other two megazones: Airport and Tor-York West.
