Harbor seals were hunted from the 1870s to 1970s until they were protected in the United States by the 1972 Marine Mammal Protection Act and in Canada under the 1970 Marine Mammal Regulations in the Fisheries Act.

Key threats include human disturbance, habitat degradation, loss of prey, and interaction with fishing gear and boats.
