75 years ago today, Canada joined its Commonwealth allies and declared war on Nazi Germany, signalling its entrance into the Second World War. And today, Canadians come together to celebrate and pay their respects to this national effort that saw a small nation rise to the greatest challenge in history, and commit sacrifices that would earn the respect of people the world over and stand the test of time.
The declaration came roughly a week after the German invasion of Poland on Sept. 1st, 1939 and the subsequent declaration of war by both Britain and France. Unlike the First World War, where Canada was obliged to become involved as part of the Commonwealth, Canada enjoyed a measure of self-determination in foreign affairs at this time and declared war autonomously. Though it was generally understood that Canada would become involved to support its allies, this decision was a significant event in the evolution of our nation.
Over the course of the next six years, Canada would enjoy a changing role in the war effort. Beginning the war as a largely unprepared participant, Canada would go on to become Britain’s most important ally for the next two years. Thereafter, Canadian forces would be a crucial arm of the British war effort, taking part in some of the toughest offensives on the Western Front and in both the air war and the war at sea.
Our first taste of combat came in the Battle of the Atlantic, which lasted from Sept. 1939 to war’s end in May of 1945. This would prove to be the longest battle of the war, and certainly one of the most crucial. Between the Royal Canadian Navy, the Canadian Merchant Navy, and the Royal Canadian Air Force (RCAF), thousands of Canadians fought and died to ensure the safe passage of troops and goods across the Atlantic to Britain.
This not only ensured that Britain did not collapse during the darkest days of the war in 1940 and 41. From 1942 onward, it was part of the largest buildup in military history, which in turn led to the D-Day landings, the liberation of France, and victory in Europe. During the Battle of Normandy (June 6th – Aug. 25th, 1944), Canadian forces distinguished themselves in the Battle of Caen and the Falaise Pocket, two key operations that led to the defeat of the Nazis in France.
Between 1939 and 1945, Canada also made major contribution to the air war through the British Commonwealth Air Training Plan and the Royal Canadian Air Force. Given that Britain was vulnerable to air strikes from Germany early in the war, Canada became the site of the Commonwealth’s pilot training, and provided countless men and women with the skills they needed to fly fighters, bombers, supply planes and sub hunters.
The RCAF would also participate heavily in the Battle of Britain and combat operations in Europe, the north Atlantic, north Africa, southern Asia, and at home. By war’s end, it would be the fourth largest air force in the world. Similarly, the Royal Canadian Navy, which provided escort to British and Allied shipping across the Atlantic, was intrinsic in hunting U-boats, and would become the world’s fifth largest surface fleet by wars end.
In addition, Canada participated in some of the most costly and ugly defeats in the war. This included the Battle of Hong Kong, one of the first battles of the Pacific Campaign which occurred on the same morning as the attack on Pearl Harbor. Here, a total of 14,000 British, Canadian, Indian and Chinese troops faced off against 52,000 Japanese Imperial soldiers and were defeated. Those that survived were taken as slaves, while those countless others were mercilessly slaughtered.
And on August 19th, 1942, the 2nd Canadian Infantry Division took part in one of the most poorly-planned operations of the war – the Dieppe Raid. Here, Canadian, British, Free French and Polish troops stormed a well-defended occupied port in Northern France and were forced to retreat. Of the nearly 5,000-strong Canadian contingent that went ashore, 3,367 were killed, wounded or taken prisoner – an exceptional casualty rate of 68%.
All told, a total of 1,187,334 Canadian men and women were mobilized to fight in the war from a population that numbered 11 million before the war. Afterward, Canada would go on to become a major voice for peacekeeping and human rights on the international stage. This was exemplified by John Peters Humphrey (a Canadian) being the principle drafter of the UN Universal Declaration of Human Rights, and Canadian troops participating in peacekeeping missions all around the world.

At the same time, some 45,400 Canadians would make the ultimate sacrifice to defeat Fascism, militarism, and genocide – close to half a percent of Canada’s total population. And I am honored to say that this past April, I was able to pay my respects at several Commonwealth cemeteries where many of them were laid to rest. This included Beny-sur-Mer, Ranville, and the Bayeux Commonwealth Cemetery.
My first cousin, twice removed, Wilmot Pettit was one of those individuals who did not make it home. As a member of the Royal Air Force, he was tasked with towing gliders into Normandy on D-Day as part of the Eastern Task Force. While flying over Grangues, his plane was shot down and he and his crew were killed. Today, his body rests at Ranville Cemetery, surrounded by many fellow Canadians and British soldiers who perished on that “Day of Days”.
This past year has been an ongoing procession of anniversaries. From the seventieth anniversary of the Normandy Invasion, to the Centennial of the outbreak of World War I, to the seventy-fifth anniversary of World War II, and now the seventy-fifth of Canada entering the war… It certainly makes one feel thankful. At the same time, it reminds us of just how fragile peace and civility are – not to mention how important.
In today’s world, there are still many people who – either out of selfishness, stupidity, grief or ignorance – seek to cause harm or profit from violence. Sadly, these people often finds themselves at the head of an army of willing supplicants. One can only hope that something other than a global effort and a major expenditure of life will not be needed to stop them before it’s too late!
