The Crown announced the new murder charge in a Toronto courtroom where McArthur appeared via video on Wednesday morning. McArthur is now charged with their murders and the murders of four other men.
Police have said they've recovered the remains of seven people from planter pots around a home in midtown Toronto where McArthur worked and stored his equipment.
Further details are expected at a police news conference scheduled for this afternoon.
Arrested in January, the Toronto landscaper has been charged with the murders of Soroush Mahmudi, 50, Andrew Kinsman, 49, Skandaraj Navaratnam, 40, Selim Esen, 44, Majeed Kayhan, 58, and Dean Lisowick, 47. McArthur had already been charged with the murders of Esen and Lisowick. Police have also executed at least two search warrants, including one for a forensic search of McArthur's apartment on Thorncliffe Park Drive, in the city's northeast.
Idsinga says the remains of alleged victim Majeed Kayhan have not been identified.
Police also released a forensic sketch of a man believed to be a victim of Mcarthur's, and said they're still trying to identify him.

Trump praised Qatar's military purchases, saying they buy "a lot of equipment from us, a lot of military airplanes, missiles". The meeting between the two leaders came after Trump in June denounced Qatar for allegedly financing terrorist groups.
Police are also waiting for warmer weather to investigate other properties associated with McArthur, Idsinga said.
Idsinga said investigators needed to identify the man so they could pursue "possibles" with hopes that DNA or dental records would match up with found remains.
Idsinga says police are now re-examining 15 cold cases dating back as far as 1975 in their investigation. He was reported missing to Peel Region police the next day.
Mr. Faizi's vehicle was found early in 2011 on Moore Ave, not far from the property where Mr. McArthur stored his landscaping tools, and where a number of the bodies have been located. They initially released a photo of the man last month and are working on tips they have received from the public.
The remains of six victims were found in planters at a Mallory Crescent home in Toronto.
The city's police board has also approved an external review, requested by Mayor John Tory, that will look into how the force handled the cases of men missing from the gay village.
The following year, McArthur is alleged to have killed Kinsman and Esen; police allege he killed Lisowick between April 2016 and March 2017. McArthur popped up on the police radar in the fall of 2017 as part of Project Prism.
