It's important to recognize that not all witnesses are created equal in this situation. I think the witnesses that you have in this motion are quite appropriately foundational witnesses.
I would like to note that we are in an election cycle municipally and we may want, through the clerks, to put a priority on requesting that the mayor be here while he is the sitting mayor of Ottawa. In a month, he won't be and he may be less available, given retirement. If there's the ability to prioritize chief Sloly and the mayor on the front end, that might be helpful in terms of timing.
It's just a suggestion.
