The mystery billionaire who let Harry and Meghan stay in his $14million mansion in Canada is reportedly Frank Giustra, a businessman whose close ties to the Clintons have caused controversy in the past.

Canadian mining magnate Giustra, 62, is said to have loaned the couple the home where they finalized their plan to scale back their royal duties over the New Year, according to The New York Post.

The couple have so far refused to refused to name the secretive multi-millionaire who loaned them the Canadian mansion.

But Page Six reports Giustra is the owner of Mille Fleurs, the seafront home close to Victoria, British Columbia. He is understood to have loaned the home for free.

Giustra is close friends with David Foster, who arranged for the Duke and Duchess to stay at the imposing home. Music producer Foster is the husband of Broadway star Katharine McPhee, a friend of Meghan's since their school days.

Ownership by Giustra would be at odds with what DailyMail.com was told by a realtor involved in the 2014 sale of the home. That person, who had to sign a non disclosure agreement, said it was bought by a billionaire who is neither Canadian nor or American for $18 million CAD - $14 million.

Giustra, the co-founder of Hollywood studio Lionsgate, is one of the biggest donors to the Clintons and is on the board of their foundation.

He ran into controversy when, in 2005, he traveled to Kazakhstan with then President Bill Clinton.

There they met the country's despotic president Nursultan Nazarbayev. Clinton's appearance is seen as helping Giustra secure a deal to start his UrAsia uranium company in Kazakhstan, which would later merge with Uranium One.

Giustra would donate $31.3 million to the Clinton Foundation in 2006 and helped start the Clinton Giustra Sustainable Growth Initiative.

Who is Frank Giustra? Frank Giustra, 62, is a Canadian mining magnate who made his money as a stockbroker. He is also the co-founder of Lionsgate, the studio behind The Hunger Games, Twilight and La La Land. The divorced dad-of-two is one of the biggest donors to the Clintons and is on the board of their foundation. Giustra's Clinton Foundation-affiliated Canadian charity kept its donors secret, which went against the 2008 promise the Clintons made as Hillary Clinton joined the Obama Administration to release all those names publicly. He ran into controversy when, in 2005, he traveled to Kazakhstan with then President Bill Clinton. There they met the country's despotic president Nursultan Nazarbayev. Clinton's appearance is seen as helping Giustra secure a deal to start his UrAsia uranium company in Kazakhstan, which would later merge with Uranium One. Giustra would donate $31.3 million to the Clinton Foundation in 2006 and helped start the Clinton Giustra Sustainable Growth Initiative. In 2016 emails showed Giustra and fellow billionaire Carlos Slim gave the Clinton Foundation an endowment of $20 million six years earlier. But reports said 'there is almost nothing in the public record' showing what happened to the money. Giustra called the controversy 'insanity, a f***ing circus'. In 2016 he received the Order of British Columbia. Advertisement

In 2016 emails then showed Giustra and fellow billionaire Carlos Slim gave the Clinton Foundation an endowment of $20 million for the Haiti Development Fund six years earlier. But reports said 'there is almost nothing in the public record' showing what happened to the money.

Giustra called the controversy 'insanity, a f***ing circus'.

The multi-millionaire who owns the home has declined to identify himself voluntarily ahead of new legislation in the Canadian province which will make it compulsory for the owners of properties to be publicly named.

An association with someone who goes to extraordinary lengths to hide their identity will raise questions over judgment as they pursue earning opportunities in their attempt to 'work towards financial independence.'

The royals declined an invitation by DailyMail.com to reveal the mystery mansion owner's identity. The couple's spokeswoman also declined to say whether they had paid for the vacation.

DailyMail.com has contacted Giustra and Foster for comment.

The owner of Mille Fleurs was apparently not known to the Duke and Duchess of Sussex until Foster introduced them.

There was no sign of Meghan Saturday at the mansion on Vancouver Island after she flew back to Canada without Harry to rejoin baby Archie, who had been left with a nanny.

In a sign of the couple's wish to spend considerable time in North America, they have moved their pet dogs to the property.

Harry and Meghan's intention to quit as senior Royals has widened the gulf between the two siblings, with William understood to be 'incandescent' over his brother's blindsiding of the Family.

It also emerged the Duke of Sussex pulled the trigger on his abdication decision because he feared his wife, who had not settled well in the UK, was 'on the brink' and could suffer a meltdown if she remained in the country permanently.

Anxious to avoid exacerbating an already tense situation, the Royal Family is keen to tread carefully. A source said: 'There is no suggestion that they will be punished or stripped of their Royal titles or HRH status. Everyone wants to find a solution to this as quickly as possible.'

After laying down a 72-hour ultimatum to aides on Friday to hammer out a solution to the Sussexes' future roles, Her Majesty summoned Princes Charles, William and Harry to her Norfolk Estate to put an end to the turmoil ravaging the monarchy - while Meghan is expected to join the discussions via a conference call from Canada.

Courtiers have quickly crashed together a document outlining several blueprints for Harry and Meghan's new position within the Royal ranks.

Mille Fleurs is officially owned by the Towner Bay Country Club Ltd.

The Towner Bay Country Club owns all 27 properties on the private Towner Park Road, just outside the small town of North Saanich.

When the homes are put on sale, the buyer does not buy the house directly.

Instead they buy shares in the country club, which gives them effective ownership of the property. The buyer's name therefore does not appear on the title of the land, which is a public document.

The office address given by the Country Club on its corporate filings is at a local law firm, Henley & Walden LLP in Sidney. The firm refused to comment.

It refused to name the shareholder to DailyMail.com.
