Donald Trump's self-imposed deadline for a first round of tariffs on Canada, Mexico, and China looms as economic observers and world leaders try to plan amid the uncertainty.

Companies, consumers and farmers across North America braced on Friday for U.S. President Donald Trump to impose 25% tariffs on Canadian and Mexican imports within hours, moves that could disrupt nearly $1.

According to Tom Kloza, the global head of energy analysis at Oil Price Information Service, if fuel producers respond to the tariffs by cutting production, gasoline prices in the Midwest could climb 15 to 20 cents a gallon, with more muted effects in other parts of the country.
