Investigators and prosecutors are meeting Tuesday to determine when and where the suspect will appear in court.
Higgins's remains were found under a bridge an hour and a half from her home last Thursday, a few days after she was reported missing.
Higgins, also 22, had left a friend's home on foot in the early hours of July 7 in LaSalle.
The walk home should have only taken her about 10 minutes, but she never made it.
The suspect will be charged in the jurisdiction where the crime occurred.
He remains in custody.
"After he was arrested, he was questioned and for now, he is still with the investigator," said police spokeswoman Mélanie Dumaresq.
