Matthew de Grood, 23, is charged with five counts of first-degree murder after allegedly stabbing the five young adults to death April 15 at a home near the University of Calgary.
He was charged after the April 15 stabbings at a party near the University of Calgary to mark the end of the school year.
The court is expected to hear the results of de Grood's second psychiatric assessment, which was done to determine if he can be found criminally responsible.
De Grood is expected to be linked to the court hearing via closed-circuit television.
Last month, the analysis for that assessment was complete but the report was not yet ready.
A forensic psychologist had interviewed de Grood and his parents, and while that will offer an expert opinion on de Grood, the judge or jury will have the final say.
Crown prosecutor Neil Wiberg said extensions for assessments are common, and were likely because of the caseload at the Alberta Hospital in Edmonton and the material the report has to consider.
Five young people were killed in the early-morning attack:
- Joshua Hunter, 23.
- Kaitlin Perras, 23.
- Zackariah Rathwell, 21.
- Jordan Segura, 22.
De Grood has been held in various psychiatric centres since his arrest.
His lawyer says the accused is currently on medication but is becoming more lucid about the events of that day in April.
A preliminary hearing is scheduled for March.
De Grood has already been found fit to stand trial on the basis of one mental-health report.
