The MUHC says it's unclear why a 44-year-old Indigenous woman was not treated when she showed up last February at the emergency room in severe pain.
Kimberly Gloade later died in March 2016. It was a painful death from Cirrhosis, chronic scarring to the liver that is no longer reversible.
Her medical insurance card had recently been stolen, and she was told by ER staff would cost $1,400 to see a doctor.
A coroner's inquest found she may have been beyond saving, but she died without knowing anything about her condition.
Gloade's family in the Mi'kmaq community of Burnt Church, New Brunswick, say they refused to treat her out of "racism and ignorance."
The MUHC says it cannot explain why she was turned away, which goes against policy to treat all patients regardless of their status or health coverage.
A spokesperson tells the CBC an investigation has been opened.
