Canadian police said they were investigating the mysterious deaths of the billionaire founder of Canadian pharmaceutical firm Apotex Inc, Barry Sherman, and his wife, Honey, who were found dead in their Toronto mansion on Friday.
The two were found dead after police responded to a medical call just before noon (1700 GMT) at their home in an affluent section of northeast Toronto.
“The circumstances of their death appear suspicious and we are treating it that way,” said Constable David Hopkinson.
Homicide detectives later told reporters gathered outside the home that there were no signs of forced entry.
Two bodies covered in blankets were removed from the home and loaded into an unmarked van on Friday evening. The property is listed for sale for nearly C$7 million ($5.4 million).
