The only thing I'll add, just very quickly, is to echo what Mr. Barnes was saying about access to historical documents.
In particular, Crown-Indigenous Relations has told us that their policy is not to transfer historical records. I'm talking about records that are over 100 years old by this point. It's not to transfer records to Library and Archives Canada if a “business case” can been seen for retaining them in the department. We have no idea what is there because we're not given access to their file lists. We don't even know what they have.
Occasionally, as Jody mentioned, when Canada reviews these claims, we'll just get arbitrary records back. If we don't know what exists, we certainly can't do due diligence on behalf of first nations that are filing legal claims against the Crown.
There are these huge gaps in the historical record. First nations have no choice but to just submit these incomplete reports. It prejudices their claim because they don't have the full picture.
