Another positive attribute of PPPs is the transfer of risk among the participants. Much of the risk inherent in large infrastructure projects can be assigned to private-sector partners in a PPP, including the risks associated with design, construction, integration of various subcontractors, sourcing of funds, and overall operations and maintenance. In the case of Canada Line, the private consortium assumed the bulk of construction and operating risks, while the regional transportation authority bore property acquisition risk. During the operating period, the regional transportation authority will assume ridership revenue risk because it controls the transportation system and related marketing and is also responsible for setting fare levels and integrating train and bus schedules. By spreading risks to the parties best suited to manage them, costly complications are much less likely to crop up later to haunt public officials.
