Canadian politicians were quick to offer congratulations and best wishes after the safe arrival of a baby boy for The Duke and Duchess of Cambridge on Monday.
Prime Minister Stephen Harper said the birth of a "future Sovereign of Canada" is a reminder of a remarkable and enduring relationship between the royal family and Canada.
Canadians are delighted to learn of the birth of The Duke and Duchess of Cambridge’s son, and we offer our heartfelt congratulations to the Royal Couple and the entire Royal Family.
The arrival of the newest member of the Royal Family, a future Sovereign of Canada, is a highly anticipated moment for Canadians given the special and warm relationship that we share with our Royal Family.
This new beginning reminds us of the remarkable and enduring relationship our country has enjoyed with generations of the Royal Family. We recall with fondness the years of unfailing service by Her Majesty Queen Elizabeth II and His Royal Highness The Duke of Edinburgh and their deep affection for and loyalty to this country. We also recall the Royal Tour by The Duke and Duchess of Cambridge who were so warmly received in Canada only two years ago. We look forward to their return to Canada and to being able to introduce their child to Canada and all Canadians.
Laureen and I send our best wishes of health and happiness to the new parents as they embark on this exciting chapter in their lives.
But Harper wasn't the only politician to weigh in online. Governor General David Johnston, Justice Minister Peter MacKay, Alberta Premier Alison Redford and Toronto Mayor Rob Ford all sent tweets shortly after the news broke.
