TORONTO -- If former Bank of Canada governor Mark Carney runs for the Liberals in the next federal election, he would add “credibility” to the party's message, says Nanos Research's Nik Nanos.

"He adds a lot of credibility on the fiscal front to the Liberals," said Nanos on the latest episode of Trend Line. "Expectations are very high."

But Nanos warns that if Carney joins the Liberal team, it wouldn't be all “sunshine” for the party.

"He'll be a significant target for the Conservatives," he said.

The possibility of Carney joining Prime Minister Justin Trudeau's team of candidates has been considered since he was a keynote speaker at the party's convention back in April, when he promised to “do whatever I can” to help “build a better future for Canadians."

Nanos thinks the speech was a 'trial balloon' ahead of an election run.

Trudeau has dodged questions about Carney's political future, refusing to say whether he has encouraged the former central banker to run. However, the prime minister did “lean on” the economist for advice on the country's COVID-19 recovery plan.

" former NDP leader Tom Mulcair told 鶹ý Channel in August 2020, suggesting that the former banker could wind up serving as the federal finance minister.

Those high expectations could lead to trouble. Nanos warned that the former banker would face intense pressure.

"That would be the one thing that I believe that Mark Carney should watch out for," warned Nanos. "Can he deliver on expectations if he decides to embark on a new career that is more political?"

He wouldn't be the first candidate to wilt under the intense pressure of a federal election campaign, with Nanos pointing to the experience of a high-profile former Liberal leader as an example.

"The Conservatives effectively defined Michael Ignatieff as 'just visiting' and he was never able to shake that."
