The government says it began gathering information about the technology after a patient at a local forensic hospital was alleged to have committed a homicide in April 2012 while absent without leave.
Andre Noel Denny was charged with second-degree murder in the death of Raymond Taavel and his trial is scheduled to begin in October.
Denny was on a one-hour unescorted leave from the East Coast Forensic Hospital the night Taavel died.
The government says the reports looked at the effectiveness of GPS monitoring for mental health patients and analyzed potential legal issues.
Constance MacIntosh of the Dalhousie Health Law Institute says electronic monitoring would not likely withstand a legal challenge.
Health Minister Leo Glavine says there is also the risk of increasing stigma for mental health patients and rising costs.
The findings suggest there is little evidence the technology decreases violations of leaves and violence.
