The news conference where Toronto Police will be giving out the details of the investigation has been scheduled for 1:30 p.m. Hours before that Bruce McArthur will be appearing in a Toronto court by video.
Police are also still reviewing seven cold case files dating back to the 1970s involving gay men who were slain in Toronto's downtown core after leaving bars popular in the LGBTQ community.
Idsinga said Faisi, who was 42 when he disappeared on December 29, 2010, was one of the three men whose disappearances were linked through Project Houston, a task force launched by Toronto police in 2012, to look into the disappearances of the three men from Toronto's Gay Village.
He has been in custody since his arrest in January. They said they had identified three sets of remains belonging to Andrew Kinsman, Soroush Mahmudi, and Navaratnam.
They have not specified how the victims were killed. "Mr. McArthur is now charged with and alleged to have committed seven murders", Idsinga said.
The remains of all but Kayhan have now been identified.
Police also remain on the scene of McArthur's east-Toronto apartment, calling it an unprecedented investigative scene.

And these are far from isolated events: In 2013, a "crazed fan" was arrested for trespassing on the Rhode Island property. Taylor Swift performs at the Z100's iHeartRadio Jingle Ball 2017 at Madison Square Garden on December 7, 2017, in NY .
No more remains have been found, but police are set to provide more information about those that have been uncovered.
Idsinga said the investigation has expanded to include 15 homicide cold cases from 1975 to 1997.
The man's nephew said Faizi visited Toronto's Gay Village but kept that a secret from family, according to CBC.
In May, investigators will begin searching 75 Toronto properties linked to the self-employed landscaper.
Toronto police are also seeking the public's assistance in identifying another potential victim, whose graphic photo was released on March 5. Later that month, McArthur was charged with first-degree murder in the deaths of Kayhan, Mahmudi and Lisowick. During Wednesday's briefing, Idsinga said they have received more than 500 tips with more than 70 possible identities for the man in the photo. He has also been charged in the killings of Selim Esen, Majeed Kayhan and Dean Lisowick.
Two frequently recurring names, police sources said, were those of two men reported missing from outside of Toronto in recent years.
McArthur's next court date is April 25.
