Investigators are awaiting the results of autopsies performed on Toronto billionaire and philanthropist Barry Sherman and his wife before determining the next steps in the ongoing probe into their suspicious deaths.

Toronto Police Const. David Hopkinson said Saturday the autopsies were being performed a day after the founder of Apotex, Canada’s global pharmaceutical giant, and his wife, Honey, were found dead in their north Toronto mansion. Police have described the deaths as suspicious, but offered no other details to date.

Sherman was founded generic drug maker Apotex in 1974, and was the chairman of the company which now employs more than 11,000 people worldwide. Apotex described their deaths as shocking and tragic.

Canadian Prime Minister Justin Trudeau tweeted that he was saddened to by the news of the sudden passing of Barry and his wife Honey.

Canadian Business magazine estimated Sherman’s worth at $4.77 billion Canadian, (US$3.65 billion) making him one of the countries richest men.

Ontario politicians who spoke out on social media said the deceased were generous philanthropists.

Minister of Health Dr. Eric Hoskins tweeted: “I am beyond words right now. My dear friends Barry and Honey Sherman have been found dead. Wonderful human beings, incredible philanthropists, great leaders in health care. A very, very sad day. Barry, Honey, rest in peace.”

Minister of Economic Development Brad Duguid also expressed his condolences on Twitter. “Deeply shocked & saddened to hear of the deaths of Barry & Honey Sherman. Philanthropists and entrepreneurs who made our province a better place to live.”
