Manitoba's attorney general says he isn't ruling out a public inquiry into how aboriginal people are treated in the health-care system.

But Andrew Swan says the government wants to wait for a final report from Judge Tim Preston, who has been presiding over a lengthy inquest into the death of Brian Sinclair.

Six years ago, the double-amputee died after waiting 34 hours in a Winnipeg emergency room to be seen for what turned out to be a treatable bladder infection.

An internal report following his death found some staff assumed he was drunk and waiting for a ride or was a homeless man seeking shelter.

The inquest wrapped up yesterday and Preston now has six months to deliver his recommendations.

Sinclair's family wants his death to be ruled a homicide.

Police have already investigated the death but did not lay any criminal charges.

The inquest heard testimony that aboriginal people face discrimination and stereotyping the minute they walk into an E-R and are less likely to receive life-saving treatment.

But Arlene Wilgosh, CEO of the Winnipeg Regional Health Authority, says a public inquiry isn't necessary because protocols have already been overhauled and cultural training for staff has been improved.

She says the money would be better spent on supporting front-line staff in the provision of care.
