Yes, all those things we sell to the U. S.; add the manufactured goods to the list.
Tariffs would cut into Canada's ability to make sales.

Some U. S. congressmen and many US ranchers and farmers would like to stop Canadian meat, poultry and farm produce from crossing the border. A sure recipe for poverty for many farmers and livestock growers.

Electricity may be an oddball. With the grid system interconnected, sometimes our supply in some areas may be from the US, and the next day the reverse. Dunno about this, but an engineer with the power company tried to explain to me how it worked, but not too successfully (we were in a refueling stop and the beer tap was open).
