In the span of just the last five months in Parliament – November 2025 through April 2026 – five opposition Members (MP) of House of Commons have joined the ruling Liberals. Their additions to the minority government of Prime Minister Mark Carney provided the Liberals with a majority government following the winning of three more seats in yesterday’s by-elections. In light of the current geopolitical situation and the tariff policies of the Trump administration, most Canadians appear to agree that a majority government would give Canada more leverage in negotiating a new trade agreement with the U.S. Crossing of the floor in the U.S. Congress among the two political parties basically never happens. This is a political phenomenon found mainly in parliamentary governments such as in the U.K., Canada and Australia.
Since four of the five opposition MPs who joined Carney’s caucus since November 2025 were Conservatives, the Conservative leader, Pierre Poilievre, has complained that the Liberals have approached and tried to convince some MPs to cross the floor. He naturally takes exception with this political move by asserting that members of the Conservative caucus were elected by their constituents as representatives of his party in Parliament. Some Conservatives have actually suggested that a by-election should be called when an MP joins another party. Sorry, but Poilievre is crying into spilled milk! As an old parable goes: “If a shepherd cannot control his flock, then he shouldn’t be a shepherd.” There are indications that some Conservatives are beginning to question Poilievre’s ability to effectively lead the party into the next federal election in three years time.
Moreover, history shows that floor crossing is one of Canada’s most dramatic political traditions. Since Confederation in1867, 132 MPs have crossed the floor, with varying degrees of success. In addition, past floor crossings have occurred involving different parties at the time. The motivations behind such dramatic political decisions can vary from policy disagreements to personal ambition, such as being appointed to a Cabinet position. Certain past high profile crossings had even sparked national rage. Today, the media has paid particularly attention given that this most recent wave of Carney-era crossings pushed the Liberal net all time figure to its highest point ever in the history of floor crossings. It would appear that those MPs deciding to do so did so because of their belief that the current PM is best suited to represent Canada and push forward policies aimed at making the Canadian economy more diverse and less dependent on the U.S. Polls have also shown that Carney’s popularity is at an all time high, well above that of Poilievre who is his closest rival.
However, when an MP walks across the House of Commons to join a different party, it represents both political calculation and personal conviction, often triggering controversy about democratic representation and voter trust. Furthermore, statistically the harsh reality of crossing the floor for most MPs who switch parties is that they struggle to win reelection in their new partisan colours. In addition, as for conservative or other party views on social issues, the PM has made it quite clear that those views will not find their way into any legislation his Liberal government will propose. Some analysts would even argue that the addition of MPs from other political stripes could be a healthy thing. In this case, the ruling Liberals will have access in caucus to different perspectives which could influence their decision making.
Now that the Carney-led government has a majority and has the votes, there will be greater expectations with respect to the speedier passage of legislation through Parliament. Already, there is growing pressure on the government to deal with the most immediate domestic issues such as affordability, economic development and employment, as well as those surrounding trade and national defence. What’s interesting is that rumours continue to surface as to the possibility of even more Conservative floor crossings, which would indeed be unprecedented!
