A jury convicted Czornobaj of two counts of criminal negligence causing death and two counts of dangerous driving causing death in the 2010 deaths of André Roy, 50, and his 16-year-old daughter, Jessie.
The young woman had stopped her car in the left-hand lane of a provincial highway in Candiac, south of Montreal, to help the ducks cross the road.
Roy's motorcycle slammed into Czornobaj's car, killing him and his daughter, who was riding on the back.
The Crown is seeking nine months in jail and 240 hours of community service.
The defence agrees with the 240 hours of community service, but is arguing for a suspended sentence with three years of probation, saying there was no criminal intent.
Czornobaj has filed an appeal for her conviction and has publicly pleaded for clemency.
Pauline Volikakis, the wife and mother of the two victims, has said she wants Czornobaj to get a sentence that reflects the gravity of her actions.
