Leave it for both !!

Leave the statue as it is so that people who believed in him , can share his legacy with their upcoming generations and people who think he was a dark mark on canada’s great history can make their future generations learn about the past.

You can remove his statue from the park but not from the history of Canada. I am from India and every year we celebrate Diwali in which we remember both the good and the evil , good inspires us to do better and bad motivates us to be kind to everyone otherwise you will also be a part of the history but for a different reason. Our first prime minister did so many wrong decisions and conspiracies but we still have streets statues institutions under his name , coz everyone has a different opinion and we should respect everyone’s belief.
