The Electoral System

Canada uses a single-member plurality voting system commonly known as First-Past-the-Post (FPTP) for federal general elections and by-elections across 343 ridings.

First-Past-the-Post (Single-Member Plurality)

Canada uses the First-Past-the-Post (FPTP) electoral system for federal elections. Canada is divided into 343 single-member ridings (electoral districts). Voters cast one vote for a candidate in their riding.

Key Rule: Plurality Wins

The candidate who receives the highest number of votes in a riding wins the seat. A candidate does NOT need an absolute majority (over 50%) — only a plurality (more votes than any other single candidate).

Riding Boundaries & Redistribution

Electoral district boundaries are independently redrawn after every 10-year national census by non-partisan Federal Electoral Boundaries Commissions to account for population shifts across provinces.

Adjust hypothetical national popular vote shares to observe how First-Past-the-Post multiplies leading vote shares into seat counts.

⚠️Educational Disclaimer: This is a simplified mathematical simulation demonstrating how FPTP riding plurality can produce seat leads larger than vote share leads. It is NOT a real electoral forecast model.
