Senate appointment onboarding: Sandra Pupatello (2025)

What the record says

Classified as appointment onboarding, not a floor crossing: this is the earliest Senate affiliation change this database records for this senator, a first move out of non-affiliated status following appointment rather than a change of allegiance. The record is retained in full and held out of crossing counts. Pending review.

   Non-affiliated→ToCanadian Senators GroupParliamentary groupRuled an appointment onboardingWhere the seat went: A parliamentary group is on one side of the change or on bothA parliamentary group is not a party and not the crossbench. It contests no election and holds no seat that voters awarded — the Senate has organised around groups rather than parties since 2016 — so moving into one carries no seat anywhere, and moving out of one is not a withdrawal to sit alone.What you may rely onThat the change involved a group rather than a party. Most such legs are in the Senate; the ones in an elected chamber are listed for review, because a breakaway group of sitting members is a closer thing to a crossing than a Senate group change is.How it countsCounted toward neither total.How the record counts it: Ruled an appointment onboardingThe ruling stored on this leg is not the one its two labels imply, and the ruling is what any published figure follows. The commonest reason is that the label changed at a general election, so the voters were asked and nothing was carried anywhere; the other is that no ruling has been made yet, which is not the same as none being needed.

   Marked as a label rather than a party: the database has no party row for this side of the transition. Overwhelmingly this means the member sat as an Independent, and there is deliberately no “Independent” party.

Revision history

Every change to this record is appended here. Nothing is edited away.

1. r3 corrected

   Reclassified as Senate appointment onboarding. Every participation on this record is a senator making the earliest Senate affiliation change this database holds for them, out of non-affiliated status following appointment - institutional onboarding rather than a change of allegiance. The record is retained in full at its original identifier; event_type moves to the "other" sentinel so it leaves the crossing-countable types, the titles name the class, and a summary states the rule. appointed_status was reset from "yes" to "unknown" on 1 participation(s): that column records whether an appointment FOLLOWED the change, which no source on disk establishes for these records. No date, person, party, participant, source, publication status or verification level was altered.

2. r2 corrected

   Corrected the stored permanent URI. It pointed at /en/crossings/sandra-pupatello-canadian-senators-group-2025, a path this site has never served, so the citation target returned HTTP 404. It now points at /crossings/sandra-pupatello-canadian-senators-group-2025, the canonical record address. No fact, date, party, participant or source in this record was changed.
