Stockshots of Canada-US checkpoints on both sides of the Stanstead-Derby Line border. US President Donald Trump delayed the start of tariffs on Canada for a month Monday. Canadian Prime Minister Justin Trudeau struck a last-minute deal with Trump to tighten border measures against the flow of migrants and the drug fentanyl into the United States. Trudeau said Canada would deploy nearly 10,000 frontline officers to help secure the border, list drug cartels as terrorists, appoint a "Fentanyl Czar" and crack down on money laundering. STOCKSHOTS
