Canadian Prime Minister Justin Trudeau and President Donald Trump have vowed to work together to provide growth and jobs for both countries.
At a news conference, the two stressed the countries' shared economic goals and international co-operation.
"We will co-ordinate closely to protect jobs in our hemisphere and to keep wealth in our continent," said Mr Trump.
The Canadian leader said they had a fruitful discussion on immigration.
But he said his country had pursued a policy of openness towards refugees without compromising security.
Mr Trudeau gave Mr Trump a framed photograph of the US president and the prime minister's father, Pierre Trudeau.
The picture was taken in 1981 when the then-Prime Minister Pierre Trudeau received an award at the Family of Man award ceremony in New York City, according to the prime minister's office.
The Society for the Family of Man is an international and interfaith organisation founded in 1963 by New York City's Council of Churches.
