Parliament Hill created Department H as a research and development program under the umbrella of the Ministry of Defense, and selected James Hudson to act as the department's administrator. During this time, he met Wolverine. When James Hudson saw a newspaper article of the Fantastic Four having been formed in the United States, he decided to form a defensive response team for Canada. When the Flight became Alpha Flight, Wolverine joined up with them amongst others.
Department H sent James Hudson in his Weapon Alpha suit to capture Wolverine and bring him back to Canada. When James Hudson found Wolverine hunting a deer, he reminded Wolverine that he was still the property of the Canadian government.
In the next attempt to reclaim Wolverine, James Hudson as Vindicator led Alpha Flight to down the X-Jet, forcing it to land using a blizzard summoned by Shaman. Alpha Flight managed to capture Wolverine and Nightcrawler. Following a fight between the X-Men and Alpha Flight, Wolverine decided to surrender himself to Alpha Flight and Department H. Yet Wolverine managed to escape from Department H and reunite with the X-Men on the X-Jet.
The Department was shut down due to operating costs, forcing the disbandment of Alpha Flight. Some time later, the decision was reversed, to a degree, with the Department being re-established solely as an organization to support Alpha Flight.
Department H sent Omega Flight (consisting of Validator, Boxx, Kingdom, and a Wendigo) to investigate one of the Origin Bomb sites left by Ex Nihilo in Regina, Canada. Validator was changed by the Origin Bomb site while the rest of the Omega Flight members were killed in action by the hostile organisms.

- According to Alpha Flight Vol 2 1 (August, 1997), the Department H's official date of inception is July 2. If bureaucratic organizations had astrological signs, its sign would be cancer.  This indicates the Department was created under this sign of the zodiac, sometime between June 20 and July 22.
