The Nunavut government is trying to claim $7.5 million from two companies.
The government alleges that Northerners were sold sub-standard gas in 2001 and 2002 which damaged their snowmobiles and outboard motors.
The case has been winding its way through the courts since 2004.
The government is seeking damages from the Northern Transportation Company Limited and the Refinery Associates of Texas Inc.
The government wants the companies to provide all documents related to the gas supply for the Kitikmeot region dating back to 1996.
Justice Earl Johnson recently ruled they will have to submit the documents by October 25.
The companies are denying all allegations.
A trial date has yet to be set.
