Justice John McMahon had the option of consecutive sentencing but chose one life sentence without eligibility for parole for 25-years.
According to Global News Canada, judges decided this week that McArthur could be eligible for parole 25 years into his sentence. He was sentenced to 11 concurrent life sentences, but applied for early parole after 15 years (the threshold at the time) and, when this was denied, applied at every future opportunity, causing the families of his victims reoccurring grief.
McArthur had pleaded guilty in a Toronto courtroom to the murders of Andrew Kinsman, 49; Selim Esen, 44; Majeed Kayhan, 58; Soroush Mahmudi, 50; Dean Lisowick, 47; Skandaraj (Skanda) Navaratnam, 40, Abdulbasir Faizi, 42, and Kirushnakumar Kanagaratnam, 37.
He killed and dismembered the men between 2010 and 2017, and allegedly hid seven of the corpses in planters and the eighth in a ravine.

McArthur was first arrested in January 2018, when he was charged with the murder of two men who had gone missing in 2017.
Partly due to the Toronto Police Department's alleged mishandling of the Bruce McArthur case, the city's Pride organization decided against allowing uniformed police from participating in this year's parade. Police say more victims may be identified.
Most of his victims were homeless, recent immigrants, or people of Middle Eastern or South Asian decent.
The prosecution said that a frequent site of the killings was McArthur's bedroom and that he repeatedly strangled his victims either with his hands or with rope and a metal bar.
Police are still reviewing a series of cold cases to see if they can find any links to McArthur but have said that so far, they believe he didn't kill anyone else.
"It is my hope that he will never again know freedom and that this sentence begins the hard journey of delivering justice to the victims of these crimes, their friends and families, our LGBTQ community, and our entire city", Tory said.
Since then, police have investigated locations around Toronto where McArthur worked as a landscaper.
Kinsman had also marked "Bruce" in his diary on June 27, 2017 - the day he disappeared.
Then he posed their bodies for photographs, with numerous images featuring the same fur coat. He was found bound to a bed with a bag over his head but otherwise unharmed. He says there's no evidence to suggest a serial killer is walking the streets of Toronto. He was last seen leaving a village bar in September 2010.
Bezan cited the gruesome case of serial killer Clifford Olson, who pleaded guilty to murdering 11 children in 1982.
"This is a crime of stark horror", prosecutor Michael Cantlon said in a statement.
The last victim, Andrew Kinsman, was superintendent of McArthur's apartment building.
