The funeral will be held this afternoon in Montreal's Sud-Ouest borough.
Higgins' body was found in a plastic bag on July 9 in Hichinbrooke, 70 kilometres from Montreal, three days after she was reported missing.
Her fiancé, Nick Fontanelli, was arrested on Monday. He's accused of first-degree murder and committing an indignity to a body in her death and dismemberment.
Fontanelli is scheduled to be back in court on Aug. 17.
The couple have two children, a four-year-old girl and three-month-old boy.
