This report delves into the contentious realm of public-private partnerships (PPPs) within transit infrastructure projects, with a specific focus on the Canadian context. The paper begins by outlining the need for infrastructure development in Canada and the shift towards PPPs as an alternative to traditional methods, which have been plagued by delays and cost overruns. It defines PPPs as agreements between public and private sectors, sharing responsibilities, risks, and rewards. However, the report then pivots to discuss the controversies surrounding PPPs, including concerns about transparency, accountability, higher costs, and potential erosion of service quality. The analysis highlights specific instances and data from Canada, examining the claims of risk transfer, the impact on public finances, and the challenges of balancing public interest with private profit. The report also touches upon the political context influencing PPP effectiveness and provides an overview of the benefits and the challenges associated with PPPs, offering a comprehensive analysis of the complexities involved in these partnerships.
