I'll be quick.
At McKinsey, it's common practice not to use their own logo on the documents they produce for their clients. The firm uses their clients' logos instead.
In this particular case, there would probably be documents produced by McKinsey bearing the Government of Canada's logo or that of a government department, whether it's a PowerPoint presentation or any other type of document.
Did McKinsey & Company at any moment use the Government of Canada's or your own department's logo on the documents they produced for internal use?
