Canadian Prime Minister Justin Trudeau on Friday joked that he is not expecting an influx of unhappy Americans across the border if firebrand Republican Donald Trump becomes president.

As Trump's popularity builds in the race for the Republican presidential nomination, Internet search providers have noted a spike in queries from Americans about moving to Canada.

Trudeau told students on the third day of an official visit to the United States, however, that the idea of emigration by voters who feared ending up on the losing side was common during U.S. election campaigns.
