The answer to your question is, plain and simple, no.
This is being imposed. As was previously stated by Robert and Jeannette, as well as by the witnesses who appeared earlier, there's a tight deadline, and this is being done because of that tight deadline.
I would only hope that the government commits to first enacting UNDRIP, but also to enacting it within a certain form that's consistent with Canadian law.
I would hope that they would take article 33 in this case, and use that as a guide when they're moving on to stage 2 of this phase, because indigenous people should be able to determine their own citizenship. We're in this problem with the Indian Act because it's been unilaterally imposed since 1876.
