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.

  Christian Dubé resigned as Quebec health minister on the same day he left the Coalition Avenir Québec caucus. This is an observed office loss, not a benefit.

How rare is this?

7 recorded transitions match leaving Coalition Avenir Québec, joining Independent and at the provincial level, across 7 events and 7 named people (Crossing the Floor Database, release 2026-08-01.1, consulted October 1, 2026). The most recent is Gilles Bélanger, April 22, 2026 — the 7th on record. The earliest on record is Youri Chassin, September 12, 2024.

6 of the 7 meet the database's publication standard; the other 1 are unreviewed leads.
1 of the 7 carry a recorded outcome after the transition; any share must be taken over those 1 and published beside that number.
Withdrawn records are excluded from this set.
No senator appears in this count: we hold Senate events, but none has passed the publication gate.
