Bernard Sherman, one of Canadas most prominent billionaires and community philanthropists, was found dead alongside his wife inside their mansion in Toronto, the media reported.
Canadian police have said they are investigating the deaths of Barry Sherman the founder of Apotex Inc. a Canadian pharmaceutical company, and Honey his wife.
Hopkinson said police were called to the Shermans' home in an upscale neighborhood of north Toronto just before noon on Friday in response to a "medical complaint".
The company manufactures and exports generic pharmaceutical drugs to more than 115 countries, according to Apotex's website.
Despite the police withholding the identities of the bodies, many friends of the couple and a number of officials confirmed the news of their death.
Forbes magazine estimated Mr Sherman's personal net worth at $3.2bn (£2.4bn), making him the 15th richest Canadian.
Neighbours told CP24 the Shermans were "the pride of the neighbourhood".
He had also become an active fundraiser for Prime Minister Justin Trudeau's Liberal party in recent years, but was criticized for holding a pay-for-access fundraiser in August 2015 that included Trudeau while being registered as a lobbyist.
State DPH: Flu-related illnesses on the uptick
As the vaccine for this year's northern hemisphere flu season is the same, that could mean the season may be especially severe. The county reminds its residents there is no live virus in flu shots and the vaccine can not cause the flu .
Toronto Mayor John Tory said on Twitter he is "heartbroken" to learn of the deaths.
"Barry and Honey were kind, good people who will be greatly missed".
Canadian Senator Linda Frum presented a medal to the couple two weeks ago.
"I am beyond words right now", Hoskins wrote in his tweet.
"Wonderful human beings, incredible philanthropists, great leaders in health care". A very, very sad day.
"Barry, Honey, rest in peace". She was involved in so many causes, some of them in the Jewish community but many not. The couple helped establish the Sherman Health Science Research Centre in 2010.
"Their visible leadership on our hospital and foundation board of directors was infused with warmth, passion and a fierce intelligence", Brent Belzberg said in a statement.
