OTTAWA—Another floor-crosser made the Liberals’ day.

Not only does Lori Idlout take them that much closer to a majority government, but it also reinforces the fact that Prime Minister Mark Carney is receiving support from across the broad political spectrum.

Until last week, only the more progressive Conservatives had made the move to cross the floor. In the case of Acadie-Annapolis MP Chris d’Entremont, he hails from the southern shore of Nova Scotia which has often flipped between the Liberals and the Tories.

The easternmost parts of the country have always leaned more heavily to the Liberals, and his riding is usually simply a Liberal/ Conservative battle.

With the exception of the Halifax area, most Atlantic New Democrats have received support based on personal appeal, rather than party label.

Jack Harris, a former long-time NDP MP and former leader of the Newfoundland and Labrador, was the only New Democrat elected in Atlantic Canada in 2015 when then-Liberal leader Justin Trudeau’s “sunny days” swept the country.

When the New Democratic Party’s interim leader Don Davies announced the floor crossing of Nunavut MP on March 10, he urged the former New Democrat to put her decision to a riding vote.

“The position of the New Democrats on floor crossing is longstanding and clear. We believe that when someone rejects the decision of their electors and wants to join another party, they should put that decision to their voters.” Davies said in a statement revealing Idlout’s decision to join the Liberals.

For the Liberals, the move was met with elation. The party is now just two seats short of a majority, and with three byelections scheduled for April 13, the numbers could soon increase by at least two.

In addition, Prime Minister Mark Carney’s capacity to attract a New Democrat into his caucus will assure left-leaning Liberals that his leadership is centrist enough to attract their voter base.

Until last week, the floor crossers were all Conservatives. Markham-Unionville MP Michael Ma joined the Liberals in December. He also represents a riding that has historically been a Liberal constituency.

The third Tory, Matt Jeneroux, was a bigger surprise because the Alberta MP doesn’t face the same level of electoral risk locally. In the last election, running as a Conservative, he won with a majority of 50.25 per cent. However, his Liberal opponent increased the Grit vote by almost 20 per cent, aided by the collapse of the New Democrats.

The current NDP slide, with the loss of party status and a leadership race where most candidates cannot speak French, will actually help the Liberals in Jeneroux’s riding.

The long-serving Tory said he crossed the floor because he was impressed by Carney’s speech in Davos, and became convinced that the global crisis demanded strong Canadian government leadership. That opened the door to his support for Carney, and a move that could also reinforce his personal popularity in the riding.

Likewise, in certain urban ridings in Alberta—and definitely in British Columbia—the Liberals’ capacity to attract former New Democrat voters will determine whether or not they can secure a majority government.

Carney has been making positive international waves and that reflects back on his popularity in Canada.

If an election were held today, there is little doubt that the Liberals would easily be rewarded with a majority.

But uncertainty in international affairs—including the war against Iran and trade agreement confusion—could make that support short lived.

Thus far, for as a non-politician, Carney has handled the situation with aplomb and insight. People trust him, and some of the most frequent comments relate to the fact that he is not a lifelong politician.

His business background and international, bureaucratic experience position him as someone who literally can make political decisions without appearing like a politician.

Davies came out early on the Idlout resignation, hoping to get ahead of the story. But even floor-crossings don’t seem to hurt this prime minister. In explaining her move, Idlout underscored the fact that that Carney is the first prime minister from the North, given his birthplace in Fort Smith, N.W.T.

She also lauded him for investments already made in Nunavut, one of the reasons she supported the last budget and helped the minority government avoid defeat.

Conservative Leader Pierre Poilievre is claiming “backroom deals” are designed to “seize a costly majority that voters reject, which will enable Liberals to balloon debt, inflate the cost of living, block resources and turn criminals loose on our streets.”

Contrary to Poilievre’s claim, the deals seem to enhance Carney’s popularity.
