ANSWER
For Parcel, ShipHawk ships from the US to anywhere in the globe, with some Canada shipping as well.
Canada-based UPS or FedEx accounts making parcel shipments to the US are considered international: the origin country should match with country of account registration.
For LTL, ShipHawk ships domestic (US to US), or US to Canada with FedEx Freight, T-Force, and SAIA. Typically, merchants shipping LTL internationally use a freight forwarder, and ShipHawk prepares the shipper's letter of instruction for those.
