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.

Corrections to this record

• Permanent citation address did not resolve

  The permanent URI published for this record was https://crossingthefloor.ca/en/crossings/frank-calder-1975. This site has never served a language-prefixed route and has no /id/ route, so that address returned HTTP 404: any citation made against it did not resolve to the record. The permanent URI is now https://crossingthefloor.ca/crossings/frank-calder-1975, the canonical record address. The record's facts, dates, parties, participants, sources and public identifier (CTF-E-000059) are unchanged; only the stored address was corrected.

  The cabinet office began in 1972, before the 1975 crossing, and is not counted as a crossing benefit.
