The Roman Catholic church operated dozens of "schools" until 1978 for indigenous children in Canada. Some 150,000 children attended these schools, where they were forcibly converted to the Semitic religion and prohibited from speaking their native language. Official numbers are that 3% of these children were killed and their bodies buried in unmarked graves. However, according to unofficial numbers, the death toll ranged from 15% to 30%. Many more were sexually and physically abused by the clergy who ran these "schools".
The church has refused to apologize for these murders and till date it hasn't paid a penny in compensation to anyone (similar to the case with all the instances of genocide carried out by Vatican ever since 1492 in the Americas). However in 2009, the Vatican released "an expression of sorrow". Well, that was 6 years before the most well known genocide perpetrator Junípero Serra was promoted as a "saint".
