Remember that the Canada Constitution Act of 1982 setting treaty agreements and obligations to the highest laws is also part of a Canadian accomplishment and contribution. It it the contribution of land to be called Canada that is diminished by the revisionists. 

We didn't do the John Wayne American way, Canada signed treaty with the Indigenous nations that had been their major trading partners for a few hundred years. Making war on your trade partners and seizing their lands would have not been Canadian character. However, politely signing treaty and then inflicting an Indian Act Terms of Surrender is another story.
