Sightings of a shirtless Justin Trudeau are causing something of a stir across Canada and internationally this summer.

The prime minister was most recently photographed shirtless while taking a break from surfing and simultaneously photobombing a couple getting married on a Tofino, B.C., beach.

A Vancouver Island wedding photographer, Marnie Recker, tweeted the photo of Trudeau on Saturday with his surf board standing several metres away from the bride, generating plenty of retweets and fanfare online.

It wasn't clear exactly when the photo was taken, but Trudeau has been in British Columbia for the past week.

A previous sighting of Canada's shirtless prime minister gained international attention.

The BBC and Time magazine reported on a Canadian family that encountered Trudeau while hiking in Quebec's Gatineau Park last month and took a selfie with the prime minister who was not wearing a shirt.

Reporting on the same Quebec encounter, American online news provider Mic called shirtless Trudeau "one of Canada's most prized national treasures."

The satirical news website the Syrup Trap poked fun at the online obsession over the prime minister's physique with a story headlined: "Family on camping trip doesn't know how to tell shirtless Justin Trudeau to leave them alone."
