Just noting the suspect walked from the Shermans home and likely walked past their former home.
The suspect was heading south on Bannatyne, according to the Star. I was looking at the route and he may have passed by Beaverhall Drive where the Shermans lived prior to 50 Old Colony. From Google maps:

He’d walk right past the Vyner Greenbelt: forested, and likely no cctv.
Their previous home is also where KW said he visited years ago and Honey confronted him about how he was spending the millions that Barry had given him. (Per the Fifth Estate program.)
Link to post where KW mentioned visiting that home:
Canada - Barry, 75, & Honey Sherman, 70, found dead, Toronto, 15 Dec 2017 #8
Barry also had issues with the construction of the home on Beaverhall. From KD’s book, page 105 of my ebook:

ETA: An early theory was that the murders were related to the construction issues at 50 Old Colony. The Shermans were found in the pool area which was a later addition to the home. The theory was that they were staged facing towards the garage and home as a ‘message’.
