The Ministry of Defence (MoD) had registered as an employer for the event in the Foyle Arena leisure centre and the Department for Communities (DFC) had asked the council for its views.
Previously, when describing his opposition to the Army’s participation, Sinn Féin councillor Christopher Jackson said that the British armed forces has had “a negative impact in this island for centuries and they are not welcome on this island”.
“From our perspective, they are not welcome in any council event or venue.”
SDLP councillor Brian Tierney had said there were “ample opportunities” elsewhere for anyone wishing to join the armed forces.
Some unionist councillors defended the armed forces attending the event.
Derry and Strabane Council said the “steer” from elected members of the governance and strategic planning committee last week had been communicated to the DfC and it would be making no further comment.
The Ministry of Defence (MoD) said that while it was disappointed the Army would not be allowed to join other organisation at the Foyle Arena, it accepted the decision.
On Tuesday, Communities Minister Gordon Lyons said that “due to the intolerance of others, people interested in a good career in the air force, navy or Army will not get the chance to hear about those opportunities at the job fair”.
