Mr. Speaker, basically it comes down to racism and colonialism. As a country, we failed to acknowledge that indigenous peoples were on these lands before we arrived, which has been perpetrated for 150 years. Only now are we starting to try to right those wrongs. Changing the oath of citizenship is a good first step. It is certainly not the only step, but it is an important one and it achieves one of the calls to action from the Truth and Reconciliation Commission.
