I will answer that question. Thank you.
First of all, it is important to mention that boards of inquiry are established by cabinet. Be it in its report on plans and priorities for 2015-2016 or in its main estimates, PCO does not request funding for boards of inquiry. The reason for that is, if no board of inquiry is established, the money that would have been requested would then be considered to be a surplus, which PCO could not use.
When a board of inquiry is created, the money set aside for that objective is considered to be a dedicated fund, reserved only for boards of inquiry. If a board of inquiry must be established, interim authorities can support it. In the meantime, funding must be requested from Treasury Board. This explains why PCO does not have any funds set aside for boards of inquiry in its report on plans and priorities for 2015-2016.
