Here’s an updated list of potential Conservative leadership candidates

The Conservative leadership race is underway and the deadline to register as a candidate and meet the first round of requirements is Feb. 27.

These candidates have been approved by the party, meaning they’ve met the early stages of the financial commitment and signatures required:

— Peter MacKay: The 54-year-old lawyer served as a member of Parliament from 1997 to 2015 representing ridings in Nova Scotia. In 2003, he became the leader of the Progressive Conservative party, and was instrumental in its merger with the Canadian Alliance to form the current Conservative party in 2004. He went on to serve in three cabinet positions in the subsequent Conservative governments. He left politics to resume his legal career. He lives in Toronto with his wife, human rights advocate Nazanin Afshin-Jam, and their three children.

— Erin O’Toole: At 47, O’Toole is currently in his third term as an MP, having left the private sector for politics to win a 2012 by-election for the Toronto-area riding of Durham. He served as Veterans Affairs minister in the last Conservative government, a post he received in part thanks to his earlier career in the Royal Canadian Air Force. He ran for leadership of the party in 2017, finishing third. He is married to events planner Rebecca O’Toole and they have three children.
