Although provincial and local governments bear primary responsibility for urban transit projects and operations in Canada, the Government of Canada engages intermittently in this policy field, mainly through research and short‐term funding programs. This article analyzes federal policy concerning urban transit over the period 2002‐2017, with a substantive focus on policy ideas—the cognitive and normative concepts that provide direction for, and shape the perceived legitimacy of, policy choices. Through a thematic content analysis of policy documents, this article explicates the paradigms, programmatic foci, frames and public sentiments that have underpinned federal urban transit policy over this 15‐year period.
