This chapter analyses the densification process of a former industrial neighbourhood in the inner city of Montreal known as Griffintown within the South-West Borough and the role of compulsory acquisition in this process. The methods of data collection included semi-structured interviews with selected stakeholders involved in the densification process. The chapter has shown that social sustainability for the area has been promoted through initiatives happening outside the compulsory acquisition process. It also analyses which planning tools were applied for the densification of the area. As stated by Breux and Bedard some large-scale redevelopment initiatives in Montreal in the early 2000s such the new Casino project and the Griffintown densification were large enough to be considered as an "Urban Project". The Ministry of Quebec Transport agreed to finance 50 per cent of a new housing project of 103 dwellingsto be located in Griffintown and completed in 2019.
