And while her last name is a familiar one for most Canadians, Mulroney herself is a newcomer to politics. Here’s a bit about her background.
Caroline Mulroney Lapham is a businesswoman, lawyer and philanthropist who graduated from Harvard and completed law school at New York University.
She is currently on leave from her job as vice-president of investment firm BloombergSen Inc., according to her LinkedIn profile.
Along with her sisters-in-law, she co-founded The Shoebox Project for Shelters, which provides care packages for women, in 2011.
Mulroney has served on the board of directors for Toronto’s Sick Kids Hospital since 2013 and is listed as a governor of the National Theatre School of Canada on the organization’s website.

Her bid for the PC leadership
Mulroney won the Progressive Conservative nomination in York-Simcoe in September. The riding has been represented by retiring Tory MPP Julia Munro since 1995.
After PC leader Patrick Brown stepped down amid sexual misconduct allegations late last month, Mulroney’s name became part of the speculation on who would come forward as a candidate to replace him.
She confirmed she’d be running for PC leader on Super Bowl Sunday. In a video posted to social media, Mulroney pointed to the economy, saying Ontario needs a government that focuses on “affordability, economic growth and opportunity.”
“People in Ontario have had enough of this Liberal government,” she said. “They’re looking for change. As a working mother of four, I worry about the future for our children and our province.”
Since confirming her leadership bid, Mulroney has received the endorsement of several PC candidates on Twitter including Rod Phillips, who was said to be considering his own campaign.
