A Canadian billionaire and his wife have been found dead at their home in Toronto in circumstances that police described as "suspicious".
Bernard Sherman is the founder of generic drug-maker Apotex in 1974 after buying the company, previously Empire Laboratories, from his uncle.
Mayor of Toronto John Tory also released a statement: "On behalf of all Toronto residents, I want to express my deepest condolences to the Sherman family".
Forbes magazine estimated Mr Sherman's personal net worth at $3.2bn (£2.4bn), making him the 15th richest Canadian. The couple is one of Canada's wealthiest and their bodies were located on Friday inside their mansion.
The police had been called to the property just before noon, apparently in response to a medical complaint. Later homicide detectives told the media outside the home that had not been any signs of a forced entry.
Police have said that they are treating their deaths as "suspicious" but have not handed over the investigation to the homicide unit at this point.
Barry and Honey Sherman’s home
Apotex released a statement on Saturday paying tribute to its founder, praising both his philanthropic efforts and what it described as his vision for health care.
The address where the bodies were found was recently listed for sale for $6.9 million.
"Today I am gutted by the loss of Honey and Barry Sherman".
Mr. Sherman, 75, founded the privately held Apotex in 1974, growing it by introducing large numbers of low-priced generic drugs that took market share from brand pharmaceuticals.
The deaths shocked the country, which knew the couple as ardent philanthropists who donated to universities, hospitals and charities.
Tory said that he was "shocked and saddened" to hear about the deaths of the Shermans but takes some solace in the fact that "their memories will live on for a long time". She also served on the boards of Mount Sinai's Women's Auxiliary, the Simon Wiesenthal Center and the International American Joint Distribution Committee.More news: United Nations blames Damascus for 'golden opportunity missed' at Syria peace talks
