Canadian Liberal leader Justin Trudeau has promised that improving relations with the Obama administration will be a top priority if elected prime minster.
He said Canada's ties with its largest trading partner have been frayed by Prime Minister Stephen Harper's hard push for the Keystone pipeline.
Mr Trudeau supports the pipeline, but says he is willing to work with the US to address environmental concerns.
The Liberal Party is leading the polls in the run-up to Monday's election.
"It'll be one of my most crucial priorities to begin once again having a productive and constructive relationship with our closest ally and neighbour," Mr Trudeau said on Friday in Toronto.
The Keystone XL would send more than 800,000 barrels a day of mostly Canadian oil to Nebraska. From there, the oil would travel to refineries and ports along the US gulf coast.
US President Barack Obama vetoed a Republican bill approving the pipeline in February.
Mr Trudeau said he wants to gain common ground with Mr Obama on "more issues than Keystone XL".
