Residential school

751 unmarked graves found at residential school in Saskatchewan

The Cowessess First Nation said the discovery was "the most significantly substantial to date in Canada".

It comes weeks after theĀ remains of 215 children were foundĀ at a similar residential school in British Columbia.

"This is not a mass grave site. These are unmarked graves," Cowessess chief Cadmus Delorme said.

The Marieval Indian Residential School was operated by the Roman Catholic Church from 1899 to 1997 in the area where Cowessess is now located in southeastern Saskatchewan.

It is not yet clear if all of the remains are linked to the school.
