The best-dressed attendees at last night’s Justin Trudeau-Mexican president Enrique Peña Nieto dinner at Casa Loma

On Monday night, Prime Minister Justin Trudeau welcomed Mexican president Enrique Peña Nieto to Canada at an official dinner at Casa Loma. The soiree allowed the two handsome world leaders the opportunity to chat and mingle—and plan for their Tuesday-morning jog—ahead of a state dinner at Rideau Hall on Tuesday night, and Wednesday night’s “Three Amigos Summit” in Ottawa, at which they will be joined by U.S. president Barack Obama.

Here are some of the stylish luminaries spotted last night.
