Chief Strategy Officer Marci Surkes spoke to The Canadian Press ahead of the cabinet swearing-in ceremony of Prime Minister Mark Carney’s new government.

Prime Minister Mark Carney is set to unveil his new cabinet at Rideau Hall on Tuesday — and it's expected to be a slimmed-down front bench meant to signal a more businesses-minded approach to government.

Marci Surkes of the government relations firm Compass Rose Group said Carney will seek to draw a sharp contrast between his government and that of former prime minister Justin Trudeau — and about one-third of the new cabinet could be new faces.

"He actually does need to signal some form of change," she said. "While Mr. Carney himself embodies change, he is surrounded at this point with a ministry of individuals who served under the previous prime minister and the previous government."

Carney also has to carefully consider who he might drop from cabinet — given the trade turbulence unleashed by U.S. President Donald Trump and a public opinion environment that soured on Trudeau and his government.

Trade Minister Dominic LeBlanc and Foreign Affairs Minister Mélanie Joly were both prominent figures in Trudeau's cabinets. They have cultivated relationships with key contacts in the Trump administration, such as Commerce Secretary Howard Lutnick and Secretary of State Marco Rubio, and are considered to have deep knowledge of their files.

"The tough decision points here for Mr. Carney are how many of these veterans, who do have deep value, can you maintain when you are trying to signal change and trying to signal that you're trimming the size," Surkes said.

During the election campaign, the Conservatives frequently accused Carney of being cut from the same cloth as the unpopular Trudeau and speculated that his cabinet would have the same faces and pursue the same policies.

Surkes also said Carney has the ability to build a cabinet that is "truly reflective of every region of this country" because Canadians elected Liberal MPs from every province and from the North.
