NDP leader introduces bill that would require floor crossers to face voters first

“While that may not be illegal, it is inherently undemocratic.”

The Liberals won 169 seats in the 2025 election, three shy of a majority government, but five MPs crossed the floor between November and March, which, coupled with the Liberals winning three byelections to replace MPs who resigned, moved them to a slim majority of 174 seats.

The five floor crossers include former Conservatives Chris d’Entremont, Michael Ma, Matt Jeneroux and Marilyn Gladu, along with Nunavut MP Lori Idlout, who left the NDP for the Liberals in March.

Deputy Conservative leader Melissa Lantsman said Tuesday voters should have some means to hold floor crossers accountable, but she hasn’t had a chance yet to look at Davies’ bill.

“We’ll take a look at that legislation. We’ll look at a number of different options to make sure that voters have accountability for the members that they elected and the party that they elected them in,” Lantsman said.

The Conservatives have adopted floor crosses previously, including in 2006, when B.C. MP David Emerson was re-elected as a Liberal in the general election, but crossed to the Conservatives and was appointed to cabinet before the House of Commons began sitting under the new Parliament.

The NDP has an internal party policy barring it from accepting a floor crossing MP into its caucus, but neither the Liberals nor the Conservatives do.

D’Entremont, who was the first opposition MP to join Carney’s Liberals, said he and other MPs who crossed the floor did speak with their constituents before making their decisions.

“We did a lot of work over the summer talking to constituents, seeing what they thought. I mean, not coming out and saying, ‘Hey we’re going to cross the floor,’ but are you happy with the direction that this party or that party is going in,” he said Tuesday.

“There is a freedom of choice that a member has,” d’Entremont said, adding that Canadians elect individual MPs, “not parties, and it’s up to that member to make a decision of how to best represent their constituents when that time comes.”

D’Entremont said “probably 80 per cent” of the constituents he’s talked to are either happy with his move or at least understood his decision.

Laura Stephenson, a political-science professor at Western University, said while voters in federal elections choose individuals to represent their communities in Ottawa, party affiliation is a key factor in those decisions.

“So the idea behind this bill is an interesting one because it’s more speaking to the reality, which is that when voters go to the polls, they are in fact choosing the party as well,” Stephenson said.

In 2006, the Manitoba NDP provincial government passed a bill similar to what Davies’ proposes, and it remained in effect until 2018 when the Progress Conservative government at that time repealed it. It was challenged in court by an a former Tory MLA who was kicked out his party and was prevented from joining another caucus without resigning and winning a byelection first.

In June 2018 a Manitoba judge ruled the law was not a violation of the Charter of Rights and Freedoms.

Library of Parliament data shows 80 MPs have switched sides over the last 25 years.

Davies said while he’s not optimistic about the Liberal government passing this bill, he’s introduced similar legislation to every Parliament since he was first elected in 2008 and he hopes parliamentarians come together to help restore faith in the system.

He pointed to Gladu telling the Sarnia Observer that it seems government MPs get more for their ridings than those in the opposition benches.

“That’s U.S.-style, southern pork-barrel politics. And I don’t think Canadians support that,” Davies said.

“So that’s another reason I’m more concerned about this bill now than I used to be, because now you have MPs who cross the floor openly saying that they think they can get more government pork in their riding. That’s not the way government should work.”
