The PRESTO program was implemented to create an integrated fare payment system across multiple transit agencies in the Toronto region, but initially faced challenges including a lack of clear governance and accountability, underestimating required skills and resources, and not properly implementing basic project processes which led to delays. A new leadership team took over and established clear governance, resolved issues, integrated the teams, and communicated extensively with stakeholders to put the program back on track. Lessons learned included the importance of basics like clear roles and change management, as well as having the right leadership and skills to make timely decisions.
