Some facts about Canadian involvement in WWII

If the number of Canadian military lost in WWII were lost today, the entire Canadian military would only have 21,000 active personnel left.

More than 1.1 million fighters suited up from Canada.

Canadians were part of the landings at Normandy. While the Americans landed at Omaha and Utah, the British forces at Sword and Gold, the 3rd Canadian Infantry Division at Juno penetrated further into France than any other Allied force. After the Normandy landings a Canadian spearhead drove northeast into the Netherlands, where the Canadians liberated that nation.

To show their appreciation to the pilots who dropped food from the air, many Dutch people painted, "Thank you, Canadians!" on their rooftops.

In 1945, the people of the Netherlands sent 100,000 hand-picked tulip bulbs as a post-war gift for the role played by Canadian soldiers in the liberation of the Netherlands. These tulips were planted on Parliament Hill and along the Queen Elizabeth Driveway. Princess Juliana was so pleased at the prominence given to the gift that in 1946, she decided to send a personal gift of 20,000 tulip bulbs to show her gratitude for the hospitality received in Ottawa. The gift was part of a lifelong bequest. Since then, tulips have proliferated in Ottawa as a symbol of peace, freedom and international friendship. Every year, Canada’s capital receives 10,000 bulbs from the Dutch royal family.

The royal family of the Netherlands moved to Ottawa until the Netherlands were liberated, and Princess Margriet was born during this Canadian exile. Princess Juliana, the only child of Queen Wilhelmina and heir to the throne, sought refuge in Canada with her daughters, Beatrix and Irene. During Princess Juliana’s stay in Canada, preparations were made for the birth of her 3rd child. To ensure the Dutch citizenship of the baby, the Canadian Parliament passed a special law
declaring Princess Juliana’s suite at the Ottawa Civic Hospital “extraterritorial”. On January 19, 1943, Princess Margriet was born. The day after Princess Margriet’s birth, the Dutch flag was flown on the Peace Tower, the only time a foreign flag has waved atop Canada’s Parliament Buildings.

Allied anti-aircraft radar operators were trained in Canada (at Clinton Ontario), to maintain the secret of radar from the Axis forces. Clinton was chosen because the shores of Lake Huron at Goderich most resembled the cliffs of England, where radar was deployed to watch for German aircraft.
