For departments that don't respect the policy, the lever the Treasury Board has is related to the deputy's delegation. Departments have delegations to do things under their own authority and others for which they require Treasury Board authority.
If we are aware of a department that is flagrantly not respecting Treasury Board policy, there is an opportunity to recommend to the Treasury Board that this deputy's delegated authority be reduced. In other words, projects they could normally do under their own authority would now have to go to the Treasury Board. That's the main lever the Treasury Board has with respect to policy.
