Biden greets Trudeau at Canada's Parliament

STORY: They are expected to discuss migration, the worsening security and humanitarian situation in Haiti, the war in Ukraine, trade and fighting climate change, officials said.

The two leaders met after Trudeau introduced Biden to institutional heads.

The migration deal, according to a final rule set to be published in the U.S. Federal Register, will allow Canada to turn back immigrants at unofficial crossings including Roxham Road, a dirt path between Quebec and New York State that a growing number of migrants use.

As part of the agreement, Canada will take in an additional 15,000 migrants over the next year on a humanitarian basis from the Western Hemisphere, a U.S. official said on Thursday.
