A "three pillar" concept of sustainability guides the current publicly funded planning and redevelopment process on Toronto's waterfront. While this concept serves as a guiding framework, sustainability is largely defined in planning and redevelopment policy and practice by multi-level public sector urban intensification policy and a reliance on the private sector-led implementation of new sustainable communities. This study connects perspectives on "policy-led gentrification" and "third-wave gentrification" with an exploration of public plans and development strategies for the new West Don Lands waterfront neighbourhood. It traces how sustainability objectives are integrated into a gentrification process driven by public sector planning and development policies and private sector development interests. Components of the integration of sustainability into gentrification practices are the sale of publicly owned waterfront lands to private developers and public sector financial and educational incentives for private real estate development that meets Leadership in Energy and Environmental Design sustainability targets.
