The practice at McKinsey & Company is to not put their logo on every document and to usurp the logos of the clients they're working with. They could, for instance, use the Government of Canada's logo or that of a government department on the documents they produce.
Can you solemnly affirm to the committee that McKinsey & Company used their own logo on all of the documents related to the contracts with your department and that they never used the Government of Canada's logo on any of the documents they produced?
