The backstory of that photo is just one more milestone in the historic bromance between Barack Obama and Canadian prime minister Justin Trudeau. As White house photographer Pete Souza explains in an Instagram caption of the image:

Earlier this year we hosted the Canadian Prime Minister for a formal State Dinner. Malia and Sasha attended as guests. Before the dinner, I did a family photo in the White House residence. But later, when the Trudeaus arrived, the two families spent some time on the Truman Balcony with their respective delegations. At one point, the Prime Minister asked if we could do a photo of he and his wife with the Obama family. Click, click, click. Then, he said I should do a photo of just the Obama’s. I could have said, “sir we already did one before you arrived.” But instead, I clicked off a few quick frames. And lo and behold, it was this picture that Justin Trudeau asked me to take which everyone loved as the choice for the 2016 White House holiday card.

There you have it: Justin Trudeau, politician, known panda cuddler, budding art director.
