I am going to move on to another question.
A letter signed on February 24, 2012, by Mr. Fonberg, Deputy Minister of National Defence, and Mr. Guimond, Deputy Minister of PWGSC, states that "some components of this risk analysis may not have been made available to the OAG for reasons of Cabinet confidence".
Is it common practice for ministers not to provide you with information and to claim reasons of cabinet confidence?
