I am informed as follows:
The Department of Justice does not have responsibility for criminal investigations. Department of Justice counsel may provide advice and assistance to the Royal Canadian Mounted Police, RCMP, and other police forces with respect to their investigations. Such advice or assistance is provided by the relevant sections of the department and the resources relied upon are those assigned to that particular function. Thus, it is not possible to provide figures on funds spent by the Department of Justice in relation to any particular RCMP investigation unless charges have been laid and the Attorney General of Canada has responsibility for the prosecution. In that instance, it might be possible to provide cost estimates for the prosecution. The budget for providing assistance to the RCMP in various contexts is allocated globally to units such as the International Assistance Group and it is not calculated by reference to individual cases.
It is the position of the Royal Canadian Mounted Police not to disclose the costs at this time as it would be harmful to the ongoing criminal investigation into this matter.
