Just as a bit of a clarification, when I spoke with my contact at parliamentary affairs at Indigenous and Northern Affairs, they mentioned that it was their opinion that there were other departments that were in a better position to answer the committee's questions, so given that information, it would be up to the committee to see if we want to move forward, perhaps by way of a motion, to request that someone appear to answer questions.
Another option is that we could hear from a number of witnesses and then perhaps invite them again later in the study if there are still questions to be asked.
