U.S. President Donald Trump says it would cost Canada US$61 billion to partner in the Golden Dome missile defence system he is planning.

The U.S. president also repeated his previous point that Canada should become a part of the United States, saying America’s northern neighbour could benefit from the project for free if it became the 51st state.
