The largest import from Canada is petroleum and it’s refined products like gasoline, diesel, heating oil, etc. About $132 billion.
The next is automobiles.
Things like Ford pickups and various auto parts is $59 billion.
Then there are a lot of minerals, gems, steel, aluminum, lumber, OSB, paper, airplanes, various commodities.
Canada is one of our largest trading partners.
Who else will buy some of those items if they stop selling a good amount to US,
Canadians buy far MORE American stuff than we buy from them. They also are NOT paying even the least amount for their own military protection and rely entirely on us for that.
That female and others like her, really need to wake up and refrain from making such pronunciamientos/threats.
