Thomas Alexander Crerar (1930)

What the record says

In 1930, in the House of Commons, the recorded affiliation of Thomas Alexander Crerar changes from Progressive / United Farmers to the Liberal Party of Canada. No source is cited for this event record: it is a legacy lead, kept from an earlier phase of the project because it points at something real, not because anyone has checked it. This entry records the affiliation and its date. It does not record why the change was made, and nothing here should be read as a statement of motive. This paragraph was assembled by machine from the rows named in it, and is pending review.

The member sat with one caucus and then sat with another, without the seat being returned to voters in between.What you may rely onThat a party gained a seat it did not win. It says nothing about why: the record separates where a member went from whether they chose to go.How it countsThe direction the floor-crossing total is drawn from, but not the total itself. A small number of legs whose labels read party-to-a-different-party are ruled election-time relabelling, and count toward nothing.

   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.

     Library of Parliament / Bibliothèque du Parlement · record transitions extract row — Thomas Alexander Crerar | MP | Progressive -> Liberal Party of Canada | 1930-02-05 — research/parlinfo-2026-08-31/transitions.csv line 202 · MUL

     PARLINFO records this change on 1930-02-05 as "Progressive" to "Liberal Party of Canada". The party labels are not word-for-word those used by this record; the source's own wording is carried in this citation's locator so the difference is visible rather than smoothed over. The live PARLINFO page is refused to non-browser clients (HTTP 403 on 2026-09-01) and renders its rows client-side, so the archived capture fixes the query but not the result set. The checkable artifact for this row is the committed extract research/parlinfo-2026-08-31/transitions.csv (882 rows, sha256 5b17f2aeb6835b2d93c456c4feb2f9c5b43f1cb22bed01fa9427a84c8fdd15e4), re-verified byte-for-byte on 2026-09-01; the row sits at line 202 of that file. This citation carries no quote_excerpt: an extract row is a data record, not a passage of the cited document, and that field is reserved for text reproduced contiguously and word-for-word from the source. Cleared 2026-09-01.

   Assumptions: Machine-assembled from this database’s own rows and from no other source. The text restates, as sentences, the participant rows attached to this record: the affiliation recorded on either side of each change, the date at the precision that row carries, the jurisdiction and chamber, whether the change is filed under a group event, and whether the event record behind it carries a citation. No date is printed finer than the row’s date_precision, so a year-precision row yields a year and never a day. Both languages are composed from the same rows rather than translated from one another. No motive, benefit, causation or characterisation of a person appears, and none may be added under this claim.

   Counterarguments: Two limits, stated rather than glossed. First, the prose is only as sound as the rows beneath it: where a party link is wrong the wrong party name is printed, and where an event is a legacy lead the sentence repeats an unverified lead — saying so, but repeating it. Second, restating a thin record fluently can make it read as established; the pending status on this claim, and the sentence inside the text naming the evidence state, are the only things that say otherwise. Four label-to-party mappings were deliberately not printed, because the party row’s name did not exist on the date of the event; the underlying links were left untouched and are still visible on the record.

   No source is cited for this claim.

What happened afterwards

Recorded outcomes only. An absence here means nothing has been recorded, not that nothing happened, and no causal link to the affiliation change is asserted unless a source establishes one.

No outcome is recorded for anyone on this event.

Revision history

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

1. r3 expanded

   Wrote summary_en and summary_fr, both of which were empty. The text is machine-assembled from this database’s own rows and from no other source: the 1 participant row attached to this event, each with the affiliation recorded on either side, the date at the precision that row carries, the jurisdiction and chamber, and whether the event record behind it carries a citation (0/1). No date is printed finer than date_precision. No motive, benefit, causation or characterisation is asserted, in keeping with the published mandate of the automated validator that signs it. Both languages are composed from the same rows rather than translated from one another. The last sentence of the text says, in the text itself, that it was assembled by machine and is pending review, so the disclosure travels with the paragraph through the API and through a copied quotation. The text is recorded as claim CTF-CL-SUM-0D58D17F4F64, kind project_analysis, assertion status pending_review. Nothing was copied or paraphrased from any encyclopaedia: the earlier removal of Wikipedia-derived prose from this project is not reversed by this change. Publication status and verification level are unchanged.

2. r2 corrected

   Corrected the stored permanent URI. It pointed at /en/crossings/thomas-crerar-1930, a path this site has never served, so the citation target returned HTTP 404. It now points at /crossings/thomas-crerar-1930, the canonical record address. No fact, date, party, participant or source in this record was changed.
