Electoral redistricting in single-member plurality systems requires drawing boundaries that satisfy competing legal, geographic, and demographic constraints, yet the tools available to to the publics they affect remain opaque, fragmented, or inaccessible. We present the Canadian Redistribution Modernization Platform (CRMP), a web application designed to support the redistribution of Canada's 343 federal electoral districts.

Built on Statistics Canada census boundary data across all thirteen provinces and territories, the platform integrates interactive map editing, real-time electoral analytics, and computational redistricting methods within an interface accessible to commissioners, researchers, and the public alike.

CRMP renders visible the trade-offs among population parity, community preservation, and geographic compactness that boundary commissions navigate—trade-offs otherwise buried in the combinatorial complexity of the mapping problem itself. We aim to provide an infrastructure for both applied redistricting practice and empirical research on boundary effects in Canadian elections.
