The Duke and Duchess of Sussex are currently bunkered down in their $23 million Canadian home as Prime Minister Justin Trudeau announces the country’s border has closed in the wake of the coronavirus

The New York Post initially reported that the couple had flown back to their new home following their farewell tour in the UK.

It is believed Meghan returned to Canada last Monday, a mere few hours after attending the Commonwealth Service alongside the Queen and other senior royal family members.

Prince Harry remained behind in the UK to attend meetings at Buckingham Palace, before he returned to his new wife and son Archie at the end of last week.

Mr Trudeau spoke to cameras while outside his residence, where he is in self-isolation, as his wife just recently tested positive for coronavirus.

It was announced on Monday that Canada is to close its borders to any person who is not a citizen or permanent resident.

The new measure comes as a move to mitigate the spread of COVID-19 in Canada, and Mr Trudeau also said airlines must turn travellers with coronavirus symptoms away from boarding flights.

From Wednesday, just four Canadian airports – in Montreal, Toronto, Calgary, and Vancouver – will be accepting international flights.

“As the virus continues its spread, we’ve decided to take increasingly aggressive steps to keep you and your families safe,” Mr Trudeau said.

Canada had at least 598 confirmed cases of COVID-19 across all 10 provinces as of Wednesday.
