Message from OKW HQ:

Date: March 7, 1943

Situation Report: After many months of planning we are now ready to execute our attack on North America. A direct assault on the United States has been ruled out in favor of an attack on Canada. Our first efforts will target a major port facility: the anchorage at Halifax, Nova Scotia. 

Operational Orders: You will launch an amphibious landing near Halifax, then lead an assault on the port itself. Intelligence feels that a direct landing at Halifax may prove too difficult to manage, but it  is up to you to determine the best approach to take in the upcoming operation.
