The British royals have a strong bond with Canada, where the Duke and Duchess of Sussex will live, in part, as they transition into their new lives.
The Queen is monarch of the Commonwealth realm and it has been her most frequent overseas destination.
She has visited more than 20 times, including a trip as a princess.
Her planned visit in 1951 was postponed when George VI underwent an operation but eventually Princess Elizabeth and the Duke of Edinburgh flew to Montreal in October the same year.
It was during this tour that they were photographed in check shirts taking part in a square dance at Government House in Ottawa.
She even picked jewellery to reflect her affection for the nation, wearing her maple leaf brooch many times.
The diamond piece set in platinum shaped as the national symbol of Canada has been worn by a succession of royal women, from the Queen Mother through to the Duchess of Cambridge.
First worn during the royal couple’s Atlantic crossing in the liner Empress of Australia, it was featured by Queen Elizabeth throughout the trip.
Her daughter Princess Elizabeth was loaned the iconic piece for her first visit to Canada in 1951 and, after she inherited it, she lent the brooch to the Duchess of Cornwall for her inaugural trip to the Commonwealth country in 2009, and also to the Duchess of Cambridge.
Kate and the Duke of Cambridge went there for their first joint official overseas trip following their wedding in 2011.
More than 1,400 journalists and photographers from across the globe covered the trip, which saw the couple criss-cross the country as they travelled to seven cities over nine days.
Thousands of Canadians flocked to Ottawa for their arrival.
The future King and Queen of Canada also took part in a dragon boat race on Prince Edward Island and wore 10-gallon cowboy hats as they opened the Calgary Stampede rodeo.
Highlights included a children’s tea party where one-year-old Charlotte was heard saying her first public words including “Pop” and “Dada”.
William said at the time: “We feel very lucky to have been able to introduce George and Charlotte to Canada.
“This country will play a big part in the lives of our children and we have created such happy memories for our family during this visit.”
Now with Harry and Meghan setting up home in Canada and the UK, it raises the prospect of whether royals on official tours to the country will also travel to see the Sussexes.
William and Harry visited Vancouver as teenagers in 1998 with their father the Prince of Wales.
The brothers also joined their parents in Canada in 1991, visiting among other places Niagara Falls with the Princess of Wales.
Charles, who will one day be King of Canada, has visited the country 18 times.
Canadian Prime Minister Justin Trudeau has his own links to the monarchy.
He revealed in an interview in 2013: “There were lunch hours where I wouldn’t eat at school because we had to rush home to have lunch with the Queen.”
Meghan lived in Toronto while filming US legal drama Suits and Harry and his future wife made their first official public appearance together in the city in September 2017 at the Invictus Games.
