What happened to Barry and Honey Sherman, what was the Canadian businessman’s net worth and do they have children?
Canadian PM Justin Trudeau has paid tribute to the billionaire's "vision and spirit"
INVESTIGATIONS are underway after billionaire Barry Sherman was found dead with his wife in their £3m Toronto mansion.
As the homicide unit takes up their case, we ask who the Shermans were and how they made their fortune.
What happened to Barry and Honey Sherman?
Barry Sherman, 75, and his wife Honey were found dead in their mansion in an affluent neighborhood in north Toronto on Friday, December 15.
Reports suggest they were found hanging above their indoor swimming pool area.
An autopsy revealed both died from ligature neck compression.
The homicide unit in Canada is now investigating their deaths. Earlier police said they were not looking for suspects.
The couple's bodies were found by their estate agent, who had been trying to sell the property. There was no sign of forced entry.
What was the Canadian businessman's net worth?
With an estimated net worth of $3.2 billion at the time of his death, Sherman was the 12th richest person in Canada.
Bernard "Barry" Sherman made his millions after founding Apotex in 1974, now one of Canada's largest drugs manufacturer and employing 11,000 staff worldwide.
Do they have children?
The couple had four children. In a family statement released on December 17, they said:
"Our parents shared an enthusiasm for life and commitment to their family and community totally inconsistent with the rumours regrettably circulated in the media as to the circumstances surrounding their 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."
What else do we know about the Shermans?
Mr Sherman is believed to be the youngest person ever to enter the University of Toronto's engineering science programme, at the age of 16, going on to receive a PhD in astrophysics from the Massachusetts Institute of Technology.
He entered the pharmaceutical trade through his uncle's Empire Laboratories, working for him while still at university before buying the company when his uncle died.
He later sold Empire, and in 1974 founded Apotex, the company that made him a billionaire and which now employs more than 10,000 people.

But he became embroiled in a family dispute, with his uncle's children seeking a stake in Apotex, arguing they had been cheated. A judge threw out their claim earlier this year.
Mrs Sherman - also a University of Toronto graduate - was a board member for several hospitals, charities and Jewish organisations.
Together they donated $50m to the United Jewish Appeal and sent over $50 million worth of medicine to disaster zones over the past year.
At the time of his death, Mr Sherman was facing an investigation as to whether he had improperly held a fundraiser for Justin Trudeau before he became prime minister.
The Canadian Prime Minister has paid tribute to the couple, tweeting "condolences to their family & friends, and to everyone touched by their vision & spirit".
