"...if groups of people are clearly still benefitting (like my ancestors)...'

Exactly how are your ancestors still benefiting from historic actions? I would suspect they are all dead.  

There is much to do, to reconcile with our FN neighbours.  We should be focusing on substantive ways of building bridges. I believe the vast majority of Canadians understand the pain and suffering that was created for indigenous people in the past, and understand the legacy of residential schools on today's generations.  To piggy back on the US debate about Confederate statues/symbols,  is not advancing reconciliation on iota.
