Hey there! I'm happy to help!
Canada is located to the C. North of the United States. You might know that Niagara Falls in New York is split between the U.S. and Canada. Since New York is in the Northern US, it means that Canada is to the North. South of the U.S. is Mexico and the U.S. borders oceans on the East and West, so the only option is North.
Have a wonderful day! :D
