A trade war between the United States, Canada, and Mexico could raise gas prices.

On Tuesday afternoon, Canadian President Justin Trudeau announced 25% retaliatory tariffs on the U.S. This move comes after President Trump slapped the allied countries with 25% tariffs. For Patrick DeHaan at GasBuddy, the moves will only force large companies to pass on the prices to everyday consumers.

To minimize the impact on gasoline prices, the Trump Administration charged a 10% tariff on Canadian energy rather than the 25% tariff.
