After Canada unveiled its plan to secure the border with the United States, Mr. Trump’s transition team attributed the action to the president elect.

The government has pledged a joint task force and aerial surveillance, as well as a host of other measures.

Canada is deploying what it calls an “aerial intelligence task force” as part of a new C$1.3 billion ($908 million) plan to address US President-elect Donald Trump’s concerns about migrants and fentanyl flowing across the northern border.
