It's national defence, Public Services and Procurement Canada and the Defence Investment Agency, which is relatively new, that would be involved in that, along with partners from the Department of Industry, ISED.
Treasury Board would have a role in terms of approvals for contracts, project authorities and getting regular status updates. This project has been under way for a while. Where the department might be seeking additional money or a change in plans, they may have to come to Treasury Board, but defence has pretty broad authorities with PSPC to manage on a day-to-day basis.
