Is Canada slipping into a 'one-and-done' party leader pattern?

When Ontario Liberal Leader Steven Del Ducasaid he would resign in the wake of last week's provincial election, he became the latest addition to a big groupof Canadian party leaders to get only one kick at the electoral can.

Conservative leaders Andrew Scheer and Erin O'Toole only got one shot. Liberal leaders Stphane Dion and Michael Ignatieffwere afforded just one opportunity each. Iain Rankin in Nova Scotia and Andrew Wilkinson in B.C. each only had a singlechance to win.

Almost all of those leaders resigned. But it certainly appeared they were quitting, amid internal party pressures, to avoid the embarrassment of being ousted.

It's not so for every leader. On the same night that Del Duca resigned after one election as leader, Andrea Horwath resigned after four atop Ontario's NDP. Stephen Harper lost his first election, before winning the next three.Robert Stanfield got three strikes before Joe Clark took over the federal Tories. The most extreme examples, Wilfrid Laurier and Mackenzie King, each led their parties in seven elections, with a few losses sprinkled in amongthe victories.

These days, party leaders who lose electionsoften (but not always) resign. Winning no doubt helps with longevity, but for those who lose, is the cutthroat "one-and-done" model on the rise?

Western University political scientistCristine de Clercysays, while there is a general lack of patience withleaders these days,it doesn't make sense to think of it as a one-way trend.

"I think we're just in another period, as we've had in the past, where public and party expectations around leaders are very stringent. And if leaders can't win, then they're out," she said.

Great expectations

The reason, de Clercy says, comes down to expectations. Leaders who fail to live up to the promise they represented to the party are left by the wayside, which is why Del Ducabowed out, she says.

The Liberals went from seven seats in 2018 to only eight seats in the recent Ontario election, and again came in third.

"The magnitude of the results last week simply were not expected," de Clercy said."Just to sketch out an alternate hypothesis, if the Liberals had believed that they would receive no seats last week and they got eight seats, he looks like a hero."

She emphasizesthat the expectations set by parties are not always "necessarily reasonable" so it's not all about the leader's performance.

Alex Marland, a political scientist at Memorial University of Newfoundland, agreesthat expectations are the main variable that determinewhether a party leader has to face the music after a losing campaign.

But healso saysthe stakes are nowgenerally higher for leaders, given their expanded role in politics and being more tied up with the party brand.

And with the advent of social media and more political coverage overall, Canadians may simply get overexposed to leaders who then "lose their shine" more quickly, he said.

The Hamilton politician, who won re-election on Thursday, was emotional after failing to become Ontario's premier in her fourth attempt

"Political leaders have a shorter shelf life than they used to," he said. "People just get tired of seeing the same leaders all the time."

They're also subject to the simple ebbs and flows of partisan popularity, or voter fatigue with a certain leader or party, he says.

And, generally, different parties have different expectations.While federal Liberal or Conservative leaders may be expected by their respective supporters to form governmentin any given election, the same might not be true for New Democrats, leading to some relative stability.

"Many of [the NDP's] leaders have suffered terrible losses, but fought a principled campaign. And the membership is expecting that and is happy with it," de Clercy said. "Whereas in contrast, for the Liberals and Conservatives, it's about power, it's about winning."

Marland sayseach party has developed its own unique culture of leadership, with the NDP often happy to be the "moral conscience of Parliament."

Women tend to have more precarious leaderships

De Clercy also says not all leaders receive the same level of charitywhen it comes to meetingexpectations. Women, she says, tend to be more precarious in their leadership.

"They are not always, but often, more prone to be challenged and jettisoned," she said. "And once there's a case to replace them ... things unfold pretty quickly."

Many female politicians also face what's called the "glass cliff" phenomenon being handed the reins at a particularly weak moment for the party.

Marlandsays Conservatives haverecently turned particularly unforgiving toward losing candidates. The party will pick a new leader this fall. And whoever that is, their fortunes will depend greatly on who is leading the federal Liberals into the next election.

If JustinTrudeau decides not to run, the new Tory leader's future will be a bit of a wildcard, Marland says.

But if Trudeau leads the Liberals once more, as he's said he will, the stakes are even higher because, after 10 years out of power, the Conservatives feel they'redue for a win.

"If Trudeau is contesting the next election ... and is returned as prime minister, I think the Conservatives would just be so angry that they would need to blame somebody, and they'd blame whoever is leader."
