A Canadian billionaire and his wife have been found dead in their home in suspicious circumstances.
Ontario Health Minister Eric Hoskins tweeted that both Shermans had been found dead, expressing his shock at the news and calling them "wonderful human beings".
Police said they learned of the deaths after responding to a midday (1700 GMT) medical call at the Sherman's home in an affluent section of northeast Toronto. "We are treating the deaths as suspicious", Toronto Police Constable David Hopkinson said in a phone interview.
Apotex, which called news of the Shermans' deaths "tragic", was recently implicated in a price-fixing scheme with 17 other drug companies and their subsidiaries. Canadian Business magazine recently listed him as the 15th richest person in Canada, with a net worth of $4.77 billion.
'Our condolences to their family & friends, and to everyone touched by their vision & spirit, ' Prime Minister Justin Trudeau wrote on Twitter.
Apotex is the world's No. 7 generic drugmaker with 11,000 employees and annual sales of more than C$2 billion in more than 45 countries, according to its website.

Police said homicide investigators are involved in the case, though the deaths have not officially been classified as homicides.
Today, the company has more than 10,000 people in research, development, manufacturing and distribution facilities world-wide, with more than 6,000 employees at its Canadian operations.
Police later said there were no signs of forced entry at the property and they were not now searching for a suspect, according to CBC. The couple were found in their home, which was up for sale.
The couple had become known in Canada for their philanthropy, and their deaths sent shock waves through the country's political elite. Neighbours confirmed that the property was the couple's home.
The Toronto Sun reported Saturday that Honey Sherman may have been killed elsewhere in the mansion - leading police to suspect a murder suicide since there was no sign of forced entry.
"Honey Sherman was a volunteer extraordinaire".
