The law requiring compulsory attendance was eliminated in 1948, while the  last residential school closed in 1996.  It's not true that "it never ended", but you're right that it is recent enough that the negative effects carry on into today.

 My heart goes out to the indigenous people and I hope they can heal. At the same time,the healing process is not helped by choosing to feel insulted by the celebration of Canada's 150 year anniversary by the vast majority of people that had nothing to do with this oppression.
