Our current PM became a G 7 the leader without a single scrap of relevant (note relevant) education, experience or accomplishment and with a reputation for making absurd remarks and being intellectually wanting but Caroline Mulroney is at the opposite end of the relevance spectrum. 

She earned a Harvard degree in Government, a law degree from NYU, and a CIM  designation from the Canadian Securities Institute.

She has held increasingly responsible executive positions in Canada and the US with  investment banking and financial firms and currently is the Vice President of BloombergSen Inc. in Toronto responsible for managing the firm's client service and business development.

She is prominent in charitable/philanthropic causes and is on several boards.

Ms. Mulroney is considered intellectually brilliant.

Her father set Canada's economic and tax policy agenda for at least 2 generations.

Michael Buble got his big break as her wedding singer but Brian chose him.  

P.S. I like Buble!
