The Supreme Court of Canada will review an appeal court's decision to unseal files related to the estates of wealthy Toronto couple Barry and Honey Sherman, who were found murdered two years ago.

Several drug companies were ordered to stop distribution earlier this month by Health Canada – another four more have also received the order.

The Shermans were found dead in their Toronto mansion last December in what police have classified as a targeted double homicide.

Brian Greenspan will speak at a news conference on Friday afternoon at Apotex headquarters in Toronto.

Apotex Inc. president and CEO Jeremy Desai has resigned effective immediately from the generic drug giant founded by the recently deceased billionaire Barry Sherman.

Nancy Belanger cites the billionaire's death in December as the reason for ending the investigation in a letter to Democracy Watch, the group that filed the initial complaints.

Barry and Honey Sherman were found dead in their Toronto home on Dec. 15, and their deaths have been deemed "suspicious."

Forensics officers and crews operating a City of Toronto sewer vacuum truck were seen at, and in front of, the couple’s Old Colony Road home before 9 a.m. Saturday.

Questions about the future of Apotex - one of Canada's biggest generic drug makers - arose after the bodies of the billionaire couple were found in their Toronto home last week.

Police have released few details of the investigation into the deaths of Barry Sherman, 75, and his 70-year-old wife Honey last week.
