They announced late Wednesday afternoon they intend to give their reasons after speaking to the child's family.
The provincial police officer was driving in Montreal-area Longueuil last February when his vehicle rammed into the one in which the child was travelling. He died a few days later.
Montreal La Presse has reported the officer was travelling at 120 km-h in a 50 km-h zone. He was on duty but was not answering an emergency call.
Until now only Montreal police have met with family members.
The issue surfaced in the national assembly earlier Wednesday when Justice Minister Stephanie Vallee said the Crown will speak to the family.
"We must avoid politicizing situations like these," Vallee told the legislature.
"That being said, the office of the Crown must, and will, meet with the family to explain why no charges were laid."
