A 2014 photo of Justin Trudeau is resurfacing on social media as Americans compare Canada's prime minister with the U.S. president.

Before he became prime minister, Trudeau regularly stopped at Montreal's subway stations to campaign and greet people. In April 2014, he was at the Jarry Metro station shaking hands and meeting people as the Liberal party leader and a Montreal MP.

"Unfortunately, the escalator was broken that day and the station isn't equipped with an elevator," recalled Adam Scotti, Trudeau's official photographer who refers to him as "the boss."

"The boss noticed this man was trying to figure out a way down, so he and a few others offered to help him."

This week, people in the U.S. widely shared the image of Trudeau as a contrast to his American counterpart, Donald Trump. During his election campaign, the U.S. president publicly mocked a reporter with disabilities.
