Efforts to see the Trans Mountain pipeline through to completion are not about punishing people from B.C., but about ensuring a project in the national interest gets built, Prime Minister Justin Trudeau said Saturday at the close of the Summit of the Americas in Lima.

"This is not about punishing British Columbians, this is not about hurting Canadians, this is about bringing forward a project in the national interest," he said.

At the summit's closing news conference in Peru, Trudeau said Sunday's meeting in Ottawa between himself and the premiers of B.C. and Alberta will be about bringing people together.

"Although there are folks on all sides of this debate who've looked to polarize and raise the temperature on this debate, the federal government has a responsibility to bring Canadians together and to do things that are in our national interest," he said.

"We will do it in such a way that doesn't seek to further polarize or raise the temperature in this debate. We are looking to continue to bring people together. We will continue to do things that are responsible to get this pipeline built."

While Trudeau emphasized his willingness to bring parties together, he remained firm in his commitment to ensure the pipeline is built.

"The conversation I will have with the premiers tomorrow [Sunday] morning will emphasize that we are going to get that pipeline built," he said.

Trudeau had initially planned to travel from Peru to Paris before moving on to London, where he is scheduled to have an audience with the Queen.

Even as Trudeau prepared to leave for Lima on Thursday, he wasn't scheduled to meet with Alberta Premier Rachel Notley and B.C. Premier John Horgan, but that changed while his plane was still on the runway when notice of the meeting was released to the media.

"It became very clear that the level of polarization around this debate required significant measures," Trudeau said of the change to his itinerary.

"I wanted to be able to sit down with the premier of British Columbia, the premier of Alberta together and discuss issues of the national interest and demonstrate the federal government's' commitment to getting this project built."

Horgan suggests he's open to compromise

Both premiers arrived in Ottawa on Saturday afternoon.

Notley did not speak with the media, but Horgan spoke with CBC News shortly after his arrival at Macdonald–Cartier International Airport in Ottawa.

"My objectives are to continue to defend B.C.'s coast and the people that live in British Columbia who are concerned about the catastrophic consequences of a diluted bitumen spill," he said.

Horgan said his government is attempting to resolve the issue through the courts, rather than by engaging in open conflict with other governments, but suggested he might be willing to listen to compromises that did not include a court-determined settlement.

"Happy to look at that. Happy to look at that, sure," he said.

B.C. Premier John Horgan says that while he is pursuing his province's opposition to the Trans Mountain pipeline through the courts, he is 'happy' to consider compromises that do not include the courts. 0:36

While at the summit in Peru, Trudeau announced that Canada is beginning "the process to join the Inter-American Convention on the Prevention, Punishment, and Eradication of Violence Against Women."

The international human rights convention calls for the establishment in the Americas of ways to protect and defend women from sexual, physical or psychological violence.

According to a statement released by the Prime Minister's Office, Trudeau also pledged another $25 million on top of the $100 million already promised toward "Caribbean reconstruction and climate resilience efforts for 2017-2022."

"I would like to thank Peru and President [Martin] Vizcarra for hosting a productive Summit of the Americas," Trudeau said in a statement. "Canada will continue to strengthen our relationships with partners across the Americas, and work toward trade that benefits everyone, builds a stronger middle class, and delivers real, tangible benefits to our communities."
