A jury has convicted an elderly Cree woman of abusing native boys at a church-run residential school in Northern Ontario.

Anna Wesley, 73, was accused of beating and kicking the boys. She was also accused of forcing them to eat the food they had thrown up.

The jury convicted her on three counts of administering a noxious substance.

In the 1950s and '60s, Wesley was supervisor of St. Anne's residential school at the Fort Albany reserve on James Bay.

Wesley was a nun at the time. She left the order in 1971.

She is to be sentenced in June.
