A year after his arrest sent shock and anger through Toronto, Bruce McArthur on Tuesday morning admitted to killing eight men from 2010 to 2017.

The self-employed landscaper was arrested in January 2018, after years of speculation within Toronto's Gay Village that a group of men who had gone missing from the neighbourhood were somehow connected.

From then on, McArthur, a stocky, bearded man who had worked part time as a mall Santa, was referred to as an alleged serial killer. The case has been covered around the world.

Ultimately, McArthur was charged in the deaths of Selim Esen, Andrew Kinsman, Majeed Kayhan, Dean Lisowick, Soroush Mahmudi, Skandaraj Navaratnam, Abdulbasir Faizi and Kirushna Kanagaratnam.

On Tuesday, he pleaded guilty to all eight counts of first-degree murder.

Appearing before Justice John McMahon in Superior Court, McArthur looked gaunt, with his beard and head shaved. As the name of each of his eight victims was read out, he replied "guilty" in a quiet voice.

Michael Cantlon, a lawyer for the Crown, revealed some details of the killings, telling the court that each murder included planning and deliberation, and that six were sexual in nature.

He said that during a search of McArthur's bedroom, police found a bag containing duct tape, a surgical glove, rope and zip ties.

Cantlon also said McArthur "staged" some of his victims after they were murdered and kept some of their items as souvenirs, including jewelry.

According to the Crown, sentencing will start this coming Monday, when more details of the case will be revealed.

'This isn't closure'

Family of the victims and others impacted by McArthur's action will have the opportunity to file victim impact statements before he's sentenced.

The court will have Farsi, Tamil and French interpreters on hand to assist family members who aren't at ease in English.

Haran Vijayanathan​, executive director at the Alliance for South Asian AIDS Prevention, has been deeply involved in supporting the victims' families and organizing community reaction.

He said Tuesday the hardest part for many families may be yet to come.

"They're going to have to relive all that loss again as they put these victim impact statements together. Whenever you have to recount the details, it brings everything back up."

Kinsman's friend Nicole Borthwick said the guilty pleas have left her feeling angry.

"This isn't closure," she told CBC News.

A sentiment also expressed by Karen Fraser, who owns the home where remains of McArthur's victims were found.

Toronto Mayor John Tory also released a statement on the pleas, writing that McArthur "is a monster that preyed on our city." Tory also said his thoughts are with the families and friends of the victims.

First disappearance in 2010

The McArthur case dates back years.

The first man to go missing was Navaratnam, who was last seen in September 2010 and who McArthur had a relationship with for a number of years.

His disappearance proved to be a turning point in the police investigation, with the lead investigator, Insp. Hank Idsinga, saying if Kinsman had not been reported missing within 72 hours, police may have missed a key piece of evidence that led them to McArthur.

In court on Tuesday, it was revealed that police collected video evidence of Kinsman getting into McArthur's van that day. Kinsman's DNA was found inside in November 2017.

McArthur was arrested two months later.

Over time, police went on to recover the remains of seven of the men in large planters at a residential property in midtown Toronto where McArthur worked. The remains of the eighth man were found in a nearby ravine.

Fraser, the owner of that property, tells reporters she met some of the men McArthur killed.

Controversy over police handling of case

The police drew heavy criticism for their investigation of the missing men, including for comments made by police Chief Mark Saunders in December 2017 — a month after McArthur became a suspect in the murder of Kinsman — that police had no evidence of a serial killer operating in the Gay Village.

In the wake of that criticism, Toronto police created the service's first-ever missing persons unit.

How the Toronto police handle cases involving missing people will also be subject to an independent review set up by the Toronto Police Services Board. The review is being advised by a panel of representatives from the LGBTQ community and other marginalized groups.

'I’m hoping it’s starting that process towards closure. We can never bring these men back,' said Det. David Dickinson of the Toronto Police Service. (Patrick Morrell/CBC)

On Tuesday, Saunders tweeted thanks to police officers for their work on the case, and pledged to offer support to the victims' families and communities.

Det. David Dickinson, one of the lead investigators in the McArthur case, echoed that sentiment, adding he believes McArthur pleading guilty "is the best possible outcome."

Asked about the review, he said "if there were mistakes, then we should learn from them."

A 'jovial' fixture in the village

McArthur was self-employed as a landscaper with a long list of well-heeled clients, and also worked as a part-time mall Santa.

He had been living with his wife, son and daughter in Oshawa, Ont., before moving to Toronto after his marriage ended in 2000.

On Halloween 2001, he attacked a man with a metal pipe in Toronto, and in 2003 was handed a two-year conditional sentence for the assault.

Ten years later, he joined Facebook and began documenting what seemed to be a busy social life, sharing photos of dinner parties and evenings out.

Many of his photos also featured young men who appeared to be of Middle Eastern or South Asian descent.

People who knew McArthur say he was a fixture in Toronto's gay village and came off as "kind," "generous" and "jovial."
