Furious Canadians are lashing out over the $1.7 million it will potentially cost to provide security for Harry and Meghan when they move to Canada.

The Queen on Monday agreed to allow her grandson and his wife to split their time between Canada and the UK while an agreement was made on their future following their shock resignation as senior royals.

Concerns were raised about the possible burden on Canadian taxpayers when it first emerged Harry and Meghan were considering a move to North America.

Following the Queen's statement, Twitter went into overdrive with some Canadians vowing to riot if they have to pay any money to help cover the cost of protecting the couple.

'If Canada ends up paying even a penny for Harry and Meghan when they live here I will riot,' one Twitter user wrote.

Another said: 'What's there to decide?! Taxpayers shouldn't have to fork out any money for these spoiled multi-millionaire brats.'

'So to get this clear. Prince Harry & Meghan with their young son get to CHOOSE to leave their home in England, they get to CHOOSE to live in Canada, even if part time, but Canadian taxpayers DO NOT get to CHOOSE to pay the security for their decisions. God bless the British way,' another tweeted.

Others took direct aim at Prince Minister Justin Trudeau after reports emerged that he had already promised the Queen that Canada would cover at least some of the security costs.

'Harry and Meghan have made clear that they do not want to be reliant on public funds in their new lives. So again, WHY DID @JustinTrudeau think he could just use CANADIAN TAXPAYER MONEY for them??? NOT ACCEPTABLE? Then tell the PM!' a Twitter user said.

'@JustinTrudeau Canadians should not pay for their security while in Canada! You make decisions on your own?! The people elected you so you should show respect and not give our tax money to the rich. We work hard for our money! They should too!!!

Another said: 'This, if true is not right, @JustinTrudeau cannot unilaterally decide this, not one Canadian taxpayer dime be spent on these elite leaches! Neither are Canadian!'

'Prince Charles and Prince William are making the right call and @JustinTrudeau should follow suit. No Canadian taxpayer should pick up Harry and Meghan's security bill. They're no longer Royals.'

Canada's finance minister Bill Morneau has since said the government has not yet spoken of the potential costs.

'No, we haven't spent any time thinking about this issue,' Morneau told reporters in Toronto on Monday.

'We obviously are always looking to make sure, as a member of the Commonwealth, we play a role. We have not had any discussions on that subject at this time.'

Harry and Meghan have close ties to Canada with California-native Meghan describing it as her 'second home' after the UK.

Meghan lived in Toronto for six years while filming Suits. It is the city where the couple enjoyed a secret five-month courtship before their relationship was revealed to the world in October 2016.

They just spent Christmas in Vancouver with their eight-month-old son Archie. The couple spent six weeks in a $14 million waterfront mansion on Vancouver Island.

It comes as the Queen said on Monday that she'd held 'very constructive' talks with Harry, his brother Prince William and their father Prince Charles in a bid to chart a course through the fallout of the bombshell announcement.

Their effective resignation last week followed a year filled with rumors of infighting between the brothers and reports of Meghan feeling unwelcome in the highly traditional and structured royal family.

'My family and I are entirely supportive of Harry and Meghan's desire to create a new life as a young family,' the 93-year-old monarch said in a statement after the first day of meetings at her Sandringham estate in eastern England.

Harry and Meghan said they wanted to 'carve out a progressive new role within this institution'.

'Although we would have preferred them to remain full-time working members of the royal family, we respect and understand their wish to live a more independent life as a family while remaining a valued part of my family,' the queen said.

The monarch stressed the couple told her 'they do not want to be reliant on public funds' but did not address the issue of whether they would keep their royal titles.

Harry and Meghan are formally known as the Duke and Duchess of Sussex. Five percent of their income is from public funds.

The rest comes from Prince Charles' Duchy of Cornwall, a hereditary private estate dating back to 1337, which funds the public, charitable and private activities of his family.

'It has therefore been agreed that there will be a period of transition in which the Sussexes will spend time in Canada and the UK,' said the queen, stressing that there were still 'complex matter' left to resolve.

'I have asked for final decisions to be reached within days,' she said.

A recent poll conducted two days before the couple's shock announcement found that more than 60 per cent of Canadians would support the appointment of the Duke of Sussex as the Governor General of Canada.

The mostly ceremonial role, which is to act as the Queen's representative in Canada, provides both a residence - Government House in Ottowa - and a security detail.

Some 61 per cent of the Canadians polled said they would support having Harry replace current governor general Julie Payette when her term expires in two years.

The poll came despite Harry never having expressed any interest in the post, which has been held by Canadians since the 1950s but was previously held by Britons.
