A quick look at the 'amigos' taking part in the 'Three Amigos' summit

The North American Leaders’ Summit will see U.S. President Barack Obama, Mexican President Enrique Pena Nieto and Prime Minister Justin Trudeau meet during a gathering that's commonly referred to as the 'Three Amigos' summit.

CTVNews.ca took a closer look at each of the North American leaders before their meeting in Ottawa on Wednesday.

Enrique Pena Nieto

Nieto, a 49-year-old father of four, began his six-year-term in 2012.

No stranger to politics, Nieto is the fifth member of his extended family to have served as the governor of the State of Mexico. More than a decade before being sworn in as the country's president, Nieto worked for a relative, Arturo Montiel Rojas, in the governor’s office.

While married to his first wife Monica Pretelini, Nieto admitted to having two children out of wedlock, one who died as an infant.

Pretelini died in 2007 of an epileptic seizure.

His second wife, Angélica Rivera, is a singer, model and telenovela actress.

Barack Obama

The Ottawa summit comes as Obama approaches the end of his eight-year term in the White House. He is expected to address Parliament following the summit.

Obama, 54, used the last Three Amigos summit in 2014 to press the former Conservative government to work with the U.S. on reducing greenhouse gas emissions. Amid growing tensions over Obama's reluctance to approve the Keystone XL pipeline, former prime minister Stephen Harper cancelled the 2015 meeting.

But relations between the Canadian and American leaders have taken a different tone since Justin Trudeau's Liberal government won the federal election last October. During an official state visit to Washington earlier this year, many quipped on social media about the budding "bromance" between Obama and Trudeau.

Justin Trudeau

While he's only served as Prime Minister for eight months, Trudeau has managed to improve relations between Canada and both the U.S. and Mexico.

Obama and Trudeau have agreed to move forward on a series of initiatives to reduce greenhouse gases. Meanwhile, Trudeau has also promised to lift visa requirements for Mexicans visiting Canada.

And a past, friendly rivalry between 44-year-old Trudeau and Nieto isn't expected to affect relations between Canada and Mexico.

Trudeau and Nieto’s attendance at last fall's APEC summit in the Philippines spurred the creation of the "APEC hotties" hashtag on Twitter. The hashtag also sparked a backlash, with many individuals using it to tweet about Mexican human rights abuses.
