Happy Justin Trudeau waves rainbow Canada flag at Toronto Pride

Justin Trudeau became Canada's first sitting Prime Minister to participate in Toronto's Gay Pride Parade, joining tens of thousands in the city's streets on Sunday.

While many photos have been taken of the popular head of state at the event, it seems that one in particular is getting people's attention online.

The photo, taken by entertainment reporter Rachel West of ET Canada, shows the Prime Minister standing in the middle of the street, happily waving a Canadian flag with the colors of the rainbow bordering the maple leaf:

The above post, by LGBT site The New Civil Rights Movement, has already been "liked" more than 33,000 times.

Toronto has celebrated Pride Week for almost 40 years. According to a report by Agence France-Presse, Toronto police have not released an official attendance count, but organizers had expected one million attendees.

Marching along with the Prime Minister were Toronto Mayor John Tory and Ontario Premier Kathleen Wynne, who is the first openly gay head of a Canadian province. — BM, GMA News
