The Canadian Museum for Human Rights has put out a call for materials on aboriginal child welfare.

The museum is working on an exhibit that depicts the human-rights violations that took place during what is known as the "Sixties Scoop" that took place from the 1960s through the 1980s in Canada.

According to museum officials, about 20,000 aboriginal children were apprehended and put into foster care or adoption — usually with white families. The policy was completely separate from Canada’s residential school system. 

Museum officials said they’re specifically looking for material from First Nations, Métis and Inuit people who have experiences in the child welfare system during that time.

Officials are accepting a number of materials, including photos and personal stories. Officials added they will require written permission from any person who might be in a submitted photograph.

More information on how to submit materials can be found on the CMHR’s website.
