A large memorial service for billionaire Barry Sherman and his wife, Honey, has been scheduled for Thursday morning, as police forensic investigators at the couple's Toronto mansion keep working to solve unanswered questions about their deaths.
The founder of generic drug giant Apotex Inc. and his wife, who were widely praised for giving millions to hospitals, charities and Jewish causes, were found dead on Friday, hanging from a railing partly surrounding their basement lap pool.
Police have deemed the deaths suspicious, and have put homicide detectives in charge of the probe even though they have not so far declared it a murder case.
Late Monday, the funeral home Benjamin's Park Memorial Chapel confirmed that a service was set for Thursday at 11 a.m. at the International Centre, a large convention centre near Pearson International Airport that can accommodate thousands. The chapel would provide no further details.
The Shermans' mansion in north Toronto remained cordoned off by police tape as forensics experts returned to the scene on Monday.
A police spokesman would only say this meant the investigation was continuing.
On Sunday, police announced that autopsies had shown the couple had died of "ligature neck compression," or strangulation with a cord or rope.
On Saturday, multiple media reports and a Toronto police source said the early theory of investigators was that Mr. Sherman may have killed his wife and then took his own life.
However, the couple's four grown children dismissed outright the suggestion that a murder-suicide was behind the deaths.
"We are shocked and think it's irresponsible that police sources have reportedly advised the media of a theory which neither their family, their friends nor their colleagues believe to be true," the family statement read.
Toronto Police Chief Mark Saunders, leaving a budget committee meeting at City Hall, declined to comment on the case on Monday.
Mr. Sherman, 75, was recently estimated to be worth $4.77-billion by online magazine Canadian Business, making him the 15th-richest person in Canada.
Ms. Sherman, 70, served on the boards of York University, the Baycrest Foundation and Mount Sinai Hospital.
Their house on Old Colony Road had recently gone up for sale with an asking price of $6.9-million.
Family and friends said the couple was planning to move into a bigger home. According to property records, a house in Toronto's posh Forest Hill neighbourhood was transferred into Ms. Sherman's name last year.
Mr. Sherman, whom friends described as a workaholic, did not show up for work on Thursday, the day before his body was found.
There was no sign of forced entry to the home and no note left behind to explain what had happened, a police source told The Globe and Mail. Police did not confirm the dead couple's identity until Sunday.
Their deaths prompted international media attention and tributes from business leaders, Prime Minister Justin Trudeau, Ontario Health Minister Eric Hoskins and Toronto Mayor John Tory.
