One of the most important federal Liberals of his generation celebrates his birthday today. Dominic LeBlanc, an anchor of the government and cabinet of Prime Minister Justin Trudeau since 2015, is turning 57. Popular on all sides of the House, he has long been considered a leading contender for party leadership if Prime Minister Justin Trudeau vacates the post. It is a personal and professional pleasure to send out birthday greetings from Art’s History to Mr. LeBlanc.
