Peel Regional Police constable Brandon Strain faces allegations of dangerous driving causing death in connection to the crash that killed 41-year old Nelson Arruda of Brampton.
Strain was driving his patrol car when it collided with Arruda, who had been riding his motorcycle back home from visiting his late daughter's grave.
The crash happened on Father's Day weekend, near Tomken and Derry Roads in Mississauga.
Ontario's police watchdog agency says it has probable cause to believe the officer committed a criminal offence in connection with the death, but did not release details.
The Special Investigations Unit is an arms-length agency that investigates situations involving police in which someone is killed, injured or accused of sexual assault.
Strain's case come to court early next month.
