Interim Conservative Leader Rona Ambrose is stacking her shadow cabinet with a healthy dose of seasoned veterans and a smattering of new faces as the party positions itself as Her Majesty's Loyal Opposition for the first time in a decade.

"I believe the team we have assembled will be the strongest Official Opposition this country has ever seen," Ambrose said in a statement, noting the party's first priority is challenging Prime Minister Justin Trudeau's "massive tax-and-spend plan."

The party, which was reduced to 99 seats in the House of Commons after the Oct. 19 vote, will have 32 shadow cabinet ministers to challenge Trudeau's ministers and their ambitious change agenda.

"I am proud to lead this team of talented and respected individuals from across Canada. Together, we will ask the government tough questions and hold them to account," Ambrose said.

Harper loyalists on the margins

The full list, released Friday, includes a few surprises — chief amongst them is Jason Kenney's absence from the front bench. Kenney, who was widely seen as Stephen Harper's most competent minister, will not hold a critic portfolio in the next session of Parliament.

As a result, he will not take the lead on any particular file during question period. Instead, he will chair the shadow cabinet committee on strategic operations, a key caucus committee that will advise the leader and other critics on question period strategy, policy and communications.

A source close to Kenney told CBC News that he specifically asked Ambrose not to give him a critic role in the shadow cabinet. A move some political observers say will free up Kenney's time to run for the party's permanent leadership.

Diane Finley, who was a staple of Harper's cabinet during his tenure in government, has been relegated to a relatively minor role: deputy critic for science, innovation and economic development, reporting to Quebec MP Maxime Bernier, who will take the lead on that critical file. She will also serve as the caucus party liaison.

And Peter Van Loan, the former government House leader, has been passed over for that role in opposition by the outgoing Speaker of the House, Andrew Scheer.

Other veterans, however, will step into prominent roles. Former justice minister Rob Nicholson will be the critic for that portfolio and Ontario MP Kellie Leitch, who is also a physician, will be the health critic.

Tony Clement, who has virtually no international experience, having served as minister of health and president of the Treasury Board under Harper, will be the critic for foreign affairs.

New female face of conservatism

But Ambrose has also tapped some of the party's best communicators to handle the hottest files.

Lisa Raitt will slide into the finance portfolio, a clear demonstration that female MPs will be at the forefront of rebuilding the Conservative Party after its defeat.

The Milton MP managed to survive the Liberal wave that swept over much of the Greater Toronto Area in the last election. She also emerged as an early critic of the government's performance and tone under Harper after the electoral defeat. Her deft communications skills and ease with the media will be pertinent in such a high-profile portfolio.

Raitt has already said a priority for the party is broadening its appeal among suburban women with children — voters like herself — a key demographic which jumped ship to Trudeau's Liberals.

Michelle Rempel, a staple on CBC's Power & Politics during the election campaign, will be the critic for the citizenship, immigration and refugees portfolio. The Tories have signalled that they have serious concerns about the prime minister's pledge to bring 25,000 Syrian refugees to Canada by the end of the year. Ambrose is pushing Trudeau to "rethink" the ambitious commitment and focus on national security considerations.

Erin O'Toole, who tried to turn things around at Veterans Affairs after a series of controversies under his predecessor, Julian Fantino, will take the lead on Public Safety and Emergency Preparedness.

He'll be up against a formidable opponent in the form of Ralph Goodale, a seasoned parliamentarian who has pledged to reform the Harper government's anti-terror legislation and bring about parliamentary oversight for the country's security agencies.

Dianne Watts, the newly-elected MP for the riding of Surrey–White Rock, will be the critic for Infrastructure and Communities. One of the main planks of Trudeau's platform was a promise to jump-start the sluggish economy through massive infrastructure investment, and deficit spending.

Watts, the former popular mayor of Surrey, B.C., and a rising star in the party, will keep an eye on the Liberals as they shovel billions of taxpayer dollars out the door.

Ambrose, who will also be critic for the status of women, has carved out some new files, including a critic for matters relating to maternal, child and newborn health, to be handled by Alberta MP Mike Lake.

Weaknesses exposed

The composition of the shadow cabinet also reveals some of the party's weaknesses after its defeat on Oct. 19. Wiped out in Atlantic Canada, Ambrose has recruited defeated MP Scott Armstrong to be their critic for the region. He will serve in that role from outside of Parliament.

The party's critic for urban affairs, John Brassard, hails from Barrie–Innisfill, a riding that is more than an hour north of Toronto. That appointment is a testament to the party's near-collapse in the country's largest cities.
