'Your insistence on returning to live in the community where the victims are memorialised and the surviving victims regularly frequent, is concerning,' the parole board wrote.

Nine-year-old Daniel Neville-Lake, five-year-old Harrison, two-year-old Milly and the children's 65-year-old grandfather, Gary Neville, were killed in the September 2015 crash.

Marco Muzzo will be released to a halfway house and must abide by certain conditions.

Muzzo pleaded guilty to four counts of impaired driving causing death and two counts of impaired driving causing bodily harm in 2016.

The news comes just days before the parole hearing for imprisoned impaired driver Marco Muzzo, who killed three children and their grandfather, in September 2015.

"In our virtually interconnected world of today that is designed to include everyone from anywhere, how can this be happening?"

The Parole Board of Canada confirmed to Global News the hearing will be April 28 at Beaver Creek Institution in the Town of Gravenhurst, where Muzzo is serving his sentence.

“I am very sickened to know that there is a chance he could be in the community," said Jennifer Neville-Lake, who lost her children and father in the collision.

Police will name all of the drivers charged with impaired-related charges in order "to further make impaired driving socially unacceptable."

"Sad that the message is not getting through," police said on Twitter.
