The Canada Strategic Infrastructure Fund (CSIF) was a federal infrastructure program that operated in the early 2000s, funding large-scale projects of national or regional significance. The program supported major projects including highways, transit, water treatment, and economic development infrastructure. Like other federal infrastructure programs, CSIF required cost-sharing with other governments. While no longer active, CSIF illustrates the ongoing pattern of federal infrastructure investment in Canada—time-limited programs with specific criteria, succeeded by new programs with different names and rules. Understanding past programs helps municipalities navigate the evolving landscape of federal infrastructure funding.
