Greeted by Canadian Prime Minister Justin Trudeau, he knelt down to give the future King of England a special greeting, but it backfired.
Raising his hand for a high-five, the three-year-old was not having a bar of it, shaking his head.
Despite George’s cold shoulder, Wills and Kate were delighted to meet Trudeau and touch down in Canada, where they last visited as newlyweds in 2011.
“Catherine and I are delighted to be back in Canada. When we were here last time, we had been married only three months,” said William.
“The warm welcome that you gave us at that important moment in our lives meant a lot to us — and we have never forgotten it.
“That is why we are so pleased that George and Charlotte can be with us in Canada this time round, beginning their own lifetime of friendship with this wonderful country.”
The royals are on their first official tour as a family of four, and will stay in Canada for eight days.
The family were all matching for the occasion in shades of blue with Kate wearing a custom Jenny Packham dress with matching headpiece and a silver Canadian Maple leaf pin to pay tribute to her hosts.
