Alleged serial killer Bruce McArthur appeared briefly by video in a Toronto courtroom this morning before his case was put over to the end of the month.
"We did not locate any additional remains", Gray said. Those factors, in combination with the frozen ground, may lead police to conducting secondary searches so they can be more thorough, spokesperson Meaghan Gray said.
Police crews have been digging in the back yard.
Idsinga said crews are wrapping up their excavation at the property and the focus of forensic teams will return to the 15 planters that have been seized from various locations.
McArthur, a 66-year-old landscaper, faces five counts of first-degree murder in relation to the disappearances of men.
At the time, Idsinga also said police were preparing to excavate in the backyard after dogs trained to sniff out human remains and a ground-penetrating radar identified "a couple of spots we're interested in".
Police began their investigation of a home on Mallory Crescent on January 18 - the day McArthur, 66, was charged with the first-degree murder of two men who had disappeared from Toronto's gay village in 2017.
Police said no further remains were found at the rear of the home and that the green military style tent in the backyard has been removed.
Toronto police have recovered the remains of at least six people and identified one of them as Andrew Kinsman.
Investigators say the 66-year-old McArthur is believed to have met his victims in Toronto's Gay Village and on gay dating apps for older and large men with names such as "SilverDaddies" and "Bear411".
In addition, he is accused of murdering Majeed "Hamid" Kayhan, 59, missing since October 2012; Soroush Mahmudi, 50, missing since August 2015; and Dean Lisowick, 47, who was slain May 2016 and July 2017.
Investigators have so far identified only one set of remains - those of Andrew Kinsman, one of the men McArthur is accused of killing - and have said they continue to analyse the others.
Once police are finished with the evidence gathered so far, Idsinga said they will re-examine "literally hundreds" of missing persons cases in search of potential links to McArthur.
