"I'm tortured by the grief I caused," Muzzo told the court at his sentencing hearing on Feb. 24.
The crash on Sept. 27, 2015, killed three young Neville-Lake children, Daniel, 9, Harrison, 5, Milly, 2, and their grandfather, Gary Neville, 65.
Two other extended family members, the children's grandmother and her mother, were injured in the crash.
"You killed all my babies," Jennifer Neville-Lake, mother of the three children, said in her victim impact statement on Feb. 23. "I miss my kids. I miss my dad."
The Crown has asked that Muzzo be sentenced to between 10 and 12 years in prison and that he be prohibited from driving for eight to 12 years.

Crown lawyer Paul Tait has said Muzzo's sentence must "reflect public abhorrence" of the offence.
Tait has acknowledged that there is no precedent for the judge to draw on when deciding on a sentence, given the number of victims and their ages. But he said Muzzo's actions were the equivalent of "having a loaded gun walking down the street."
Muzzo was driving an SUV that collided with the minivan carrying the Neville-Lake family at Kipling Avenue and Kirby Road, north of Toronto. He had returned from a trip to Miami on a private jet on the day of the crash, picked up his Jeep from the airport parking lot and driven off.
The SUV, according to an agreed statement of fact read in court, was travelling at 85 kilometres an hour when Muzzo went through a stop sign and struck the minivan, hitting the driver's side.
His blood-alcohol content at the time of the crash ranged from 0.19 to 0.25 per cent, which is two to three times the legal limit in Ontario.

Police officers who interviewed Muzzo at the scene said he smelled of alcohol, his eyes were glassy, and he tried to use the car to keep his balance. He was also unable to understand instructions from the officers, and urinated on himself.
Traffic and weather conditions were not a factor in the crash.
It was only after he arrived at the police station that Muzzo learned four people had died, court heard.
Full responsibility
Muzzo was released on a $1-million bail and strict conditions after pleading guilty.
Brian Greenspan, Muzzo's defence lawyer, declined to comment when reached by email on Monday. He said the sentencing submissions were made on Feb. 23 and 24.
Greenspan has said that Muzzo has accepted "full responsibility" for what he did.
At the sentencing hearing, Greenspan submitted 92 letters of support for Muzzo, from friends, family members, neighbours and co-workers.
Greenspan told the court that Muzzo's actions amounted to "a terrible decision made by a very good person."
"It should be clear that the Muzzo family, and in particular Marco Muzzo, are heart-stricken by the grief that's been caused," Greenspan said.
Muzzo's family owns the drywall company Marel Contractors and is worth nearly $1.8 billion, according to Canadian Business magazine.
Muzzo had never been convicted of a criminal offence until he pleaded guilty on Feb. 4, according to the Ontario Ministry of the Attorney General.
