U.S. barges carrying gasoline are headed to Canada’s west coast to deliver much-needed fuel to a region cut off from the rest of the country after last week’s rainstorms brought flooding and landslides that damaged transportation links. Gasoline is in short supply in parts of Canada’s westernmost province of British Columbia including in Vancouver, home to the nation’s largest port and the country’s third-largest city. The arriving barges will help alleviate a fuel shortage in a province where some gas stations have been forced to close temporarily due to empty pumps.
