Those who have said they will run (1):

Bryan Brulotte – The CEO and chair of employment firm MaxSys Staffing and Consulting and veteran political organizer told CBC News on Dec. 15 that he will run. He is not a household name, but has deep roots within the party going back more than 25 years.

Those thinking of running (11):

Erin O’Toole—Conservative sources told the Toronto Star that the Conservative foreign affairs critic and former leadership candidate is preparing to enter into the race. CBC News also reported he told several high-profile Tories at a Toronto gathering last week that he intends to run.

Rona Ambrose—According to a source that spoke to CTV News, the former interim Conservative Party leader is thinking over the possibility of a leadership bid. The source said Ambrose is taking “the time to think it over” after enjoying a transition that has her “squarely entangled in the private sector.”

Peter MacKay—Sources also told the Star that MacKay’s camp is also mobilizing for a run. However, the former Progressive Conservative leader and Harper-era cabinet minister told the Halifax Chronicle-Herald on Dec. 13 that it’s “too soon” to make a decision, although he did not rule it out.

Pierre Poilievre—The Conservative finance critic and vocal pest of the Liberals in Question Period told reporters on Monday that “it’s too early to say” whether he would run for leadership. According to the Star, he did have some seemingly prepared ideas about the qualities the next leader should have.

Michelle Rempel Garner—The Conservative innovation critic and high-profile MP from Alberta told Global News’ The West Block on Dec. 15 she isn’t ruling out a leadership bid. She said the next leader must be “really bold and wants transformative policy” and will support the rights of Canadians of all backgrounds.

Michael Chong—The former leadership candidate and Ontario MP who holds centrist beliefs told reporters on Dec. 13 that he was considering another crack at the job. He also said he’s unsure whether he will back a carbon tax after members voted against his push for that in 2017.

Marilyn Gladu—The Conservative health critic told reporters last week she’s not ruling out plans to run for the leadership. She said she will be ready to confirm her decision after the holidays. Gladu, an Ontario MP, said she’s pro-choice and won’t fight the carbon tax.

Candace Bergen – The Conservative House leader told CTV’s Question Period that she isn’t ruling it out, although she cautioned it is “very, very early.” The Manitoba MP had served as a Minister of State in the Harper government.

Jean Charest—Sources close to the former Quebec premier told Radio-Canada this week that he is thinking of running. Charest hadn’t been seriously considering a leadership run before several sitting and former MPs reached out and urged him to do so, the sources said.

Michael Fortier—Former Conservative MP John Reynolds told The Hill Times that Fortier, a former trade minister and now the vice-chairman of RBC Capital Markets, has been reaching out to key players in the party to explore the possibility of running for the top job. La Presse also reported that Fortier is interested.

Rick Peterson—The Alberta businessman told The Hill Times last week that he also considering tossing his hat into the ring. He placed 12th in the 2017 leadership race and is president of investment firm Peterson Capital and founded a pro oil and gas advocacy group.
