That's an excellent question. I'd encourage you to ask Canada Border Services Agency.
Many departments have their own procurement arm that is there to help ensure policies are followed and best practices are there. Oftentimes, they might work with Public Services and Procurement Canada to ensure there is good competition and the best value for money is achieved, but what we found here, in this case, was that individuals were directly working with Public Services and Procurement Canada and they weren't always involving their own procurement directorate.
We made a recommendation around that being a best practice that really should be used. They're there because they are experts in contracting and can help ensure that a contracting file is well supported and that all of the decisions that should be in there are well documented.
