Canadian floor crossings in 2026

Five MPs have crossed the floor to Mark Carney's Liberals.

Poilevre thinks the constituents should sign petitions to ask for their recall.

But he should narrow his request - in two of the five cases the Conservative and NDP had had support from less than half the votes anyway.

and in four of the cases the Liberal voters had been within 2000 votes of the Conservative anyway.

So even if the Liberal candidate of 2025 is not now representing the riding, at least an MP who votes along Liberal lines is, and a good portion of the constituents are likely happy with that.

Note that in four of the cases the riding boundaries are strictly arbitrary and the voter is lumped together with an odd assortment of others.

Only the Nunavut riding, covering a whole Territory, makes sense on the ground.

===========================================

"... 273 MPs have crossed the floor since Confederation; of these, 55 crossed the floor twice and 9 crossed three times.

Most “floor-crossing” actually occurs on the same side of the floor, between ranks of the opposition.

Literal floor-crossing, from the opposition to the government or the government to the opposition, constitutes about 40% of the party switching of sitting MPs, and is equally common in both directions."
