Trudeau wore a Canada jersey, and showed off his Haida raven tattoo.
Justin Trudeau, Canada's prime minister, is in New York on a three-day visit to sign the Paris climate treaty and promote Canada's climate agenda.
Work aside, he found some time to sneak in a little boxing, one of his favorite sports.
He sparred with Yuri Foreman, a professional boxer, at the famous Gleason's Gym in Brooklyn, shortly after giving a talk on climate change at NYU, according to The Daily Mail.
Trudeau made headlines last week for astounding reporters with his in-depth knowledge of quantum computing - a subject most world leaders know nothing about.
