Lots of Europe has ethnic strife and tensions. Bosnian / Serbian. Czech / Slovak (until recently). Spain has its breakaway ethnic movements. Ireland like others mentioned is a close analogue.
Should different Slovak communities in the Czech Republic have their own lands and make their own laws? What if they're living in the same village as Czechs, how will they split the territory there?
There is simply no valid comparison between how populations in Europe live and have developed up to today, and how things sit in Canada with the First Nations.
And note, the Basque country in Spain is already an autonomous region with significant ability to do its own governance. The Basques there have been practicing their own traditions and using their own language since the fascist dictatorship fell. The Catalans of Catalunya (one of the richest regions of Spain, mind you) also speak their own language and are not in any other way culturally suppressed, again, since the fascist dictatorship fell. The reason for their struggle for independence is mostly their perception that they are being dragged down economically by the poorer parts of Spain (i.e. the strictly Spanish-speaking South).
The English starved them to death. The English forcibly displaced them. The English stole their resources.
The English even forbade them from speaking their language.
So what exactly should the English learn from Canadians today? Even the Irish in Northern Ireland have more freedom and autonomy than the First Nations have in Canada, not less.
Russian spending on 'internal security' is legendary.
