Overview

This archive follows published nationwide federal vote intention across current and historical election cycles. The chart preserves individual poll dates and party values, while the headline summary remains a descriptive national reading rather than a seat estimate.

Electoral system context

Canada elects one member in each federal electoral district, with the candidate receiving the most votes elected. National vote share can therefore diverge from seats when support is concentrated differently across provinces, regions and individual districts.

Party and bloc rationale

The local balance compares the Liberal Party with the Conservative Party. The NDP, Bloc Québécois, Greens, PPC and historical parties are excluded rather than forced onto either side. The pairing is a compact navigation device and does not describe every party or imply international equivalence.

Polling limitations

National samples can mask large regional differences, particularly for parties that contest or draw support from only part of the country. Separate election-cycle source tables create genuine blank periods in the long archive, and pollster methods, undecided treatment and fieldwork timing remain important when comparing rows.

Bloc summaries use complete paired polls within 45 days of the latest archive record, weighted by recency and sample size. Both sides use the same eligible polls. The tracker and map show the number of complete polls and their supporting date, which can precede the latest archive record; missing parties are not assigned zero. The comparison’s latest-poll balance is a separate individual observation.
