Canadian Governor General David Johnston on Thursday announced the country will be having royal visitors in May. The Prince of Wales, Charles, and the Duchess of Cornwall, Camilla, will be visiting Manitoba, Nova Scotia and Prince Edward Island (P.E.I.) four months from now.

Robert Ghiz, P.E.I. Premier, said the island residents are much excited since the royal visit coincides with the 150th anniversary of the meeting of the Fathers of Confederation.

"It is a true honour," Mr Ghiz said in a statement.

The last time P.E.I. went abuzz was in 2011 when it played host to the royal visit of the Duke and Duchess of Cambridge, Prince William and his wife Kate.

"We look forward to the opportunity to once again host members of the royal family in our beautiful province."

But while Canada maybe excited to see the royals again, an anti-monarchy group however said hosting them is not easy on every Canadian taxpayer's pocket.

The 2009 visit of Charles and Camilla cost taxpayers $1.7 million, according to the Globe and Mail. The 2010 visit by no less than Queen Elizabeth cost $2.8 million. Prince William and Kate's tour in 2011 cost $1.2 million.

"We welcome royal visits due to the increased public interest in the monarchy/republic debate that they generate," Tom Freda from the Citizens for a Canadian Republic told Yahoo Canada News.

"However, while we recognize that the reasonable cost of visits by the Queen and Prince Phillip should be paid for by Canadians, we are absolutely against paying for her other family members.

"As you know, even our prime minister's and governor general's children and grandchildren do not get taxpayer-funded travel expenses in Canada. We don't believe the Queen's should either."

The royals will be visiting upon the invitation by the government of Canada.

"I am pleased that Their Royal Highnesses will be joining us in a few months' time as Canada enters a five-year period of significant national celebrations, beginning with the centennial of the outbreak of the Great War and the 150th anniversary of the Charlottetown and Québec City Conferences, which led to the creation of the Dominion of Canada," Prime Minister Stephen Harper said in a statement.

This Canadian visit will be the 17th for Prince Charles and the third for the duchess.
