McArthur was arrested and charged with two counts of first-degree murder January 18 as part of Project Prism, the investigation into missing men Andrew Kinsman and Selim Esen in Toronto's Gay Village area.
McArthur has now been charged for killing three additional men: Majeed Kayhan, 58, Soroush Mahmudi, 50, and Dean Lisowick, 47. They charged him with the murders of two gay men, Selim Esen, 43, and Andrew Kinsman, 49.
The men praised efforts to expose systemic sexual misconduct since revelations stemming from Hollywood past year, and denounced critics who say the #metoo movement has gone too far and demonizes men.
The three additional counts were announced as investigators also revealed that they discovered dismembered remains in the bottom of large planters after searching a property at Mallory Crescent in midtown Toronto that was linked to the self-employed landscaper.
McArthur worked at approximately 30 properties in Toronto and police have searched the majority of them. This brings the total number to five, and police believe there are still more victims.
"We do believe there are more [victims] and I have no idea how many more there are going to be", Idsinga said. The last two victims we've identified don't quite fit the profile of the earlier victims.
Police said McArthur was in a relationship with one of his alleged victims, but have not provided information about any connections to the others, according to the Star.
"It's a serial killer - alleged serial killer", Idsinga said.
"Assistance from outside agencies, including the Ontario Provincial Police, the province's forensic pathology services and the Centre of Forensic Sciences is being utilized to search these premises", Idsinga said.

With 4:33 left in the third quarter, Andre Roberson slipped when he tried jumping for the ball and fell hard on his back. On Saturday, Thunder swing man Andre Roberson reportedly ruptured a patellar tendon, likely ending his campaign as well.
Police investigated his death as part of Project Houston, which ran from November 2012 to April 2014 and probed the disappearances of three men who went missing from Toronto's gay village.
Mahmudi was reported missing in August 2015.
The Globe and Mail has reported that McArthur and Kayhan also had a relationship.
However, police have not ruled out the possibility of further victims from outside the Church district.
He said: 'We believe there are more remains at some of these properties that we are working to recover.
Tory said that while there are "many, many questions" that remain unanswered about how the police investigation into McArthur unfolded and on what "time basis" it did, he said that those questions can't be fully addressed until after the legal proceedings against McArthur are concluded.
McArthur is due in Toronto provincial criminal court on February 14.
While police are confident these men were murdered, the job of trying to match up their DNA with remains is daunting.
