Canadian Prime Minister Justin Trudeau on Sunday marched in Montreal's annual LGBT Pride parade.
“I am proud to be the first prime minister to participate in the #FierteMTL parade,” Trudeau tweeted in French using the parade's hashtag.

Thousands of people lined the parade route to greet Trudeau.

This is Trudeau's third such appearance of the summer. He also joined parades in Toronto and Vancouver.

Two girls marched in the parade holding a banner with the names of the 49 people who died in a mass shooting at a gay nightclub in Orlando in June.

Trudeau has said that his government will focus this year on transgender rights. A bill unveiled in May would prohibit discrimination based on gender identity.
