A neighboring country of the US and a member nation of the NATO, Canada apprehended that behind the Norths invasion of South Korea, there was the Soviets desire of expansion. For this reason, Canada announced that the North Koreas invasion should be repelled with combined efforts of the UN nations. Five days after the war broke out, the House of the Commons of Canadian government came to an unanimous agreement on helping Korea, saying that we would give full support to any of the Canadian governments measures taken to demonstrate the efficiency of the collective security.

On this day, Prime Minister Luis Roland also said that we should take collective security actions under the UN authority,

Canada sent a brigade-level military forces as Turkey did. In mid- February 1951, the 2nd Battalion(PPCLI) was the first unit committed to Korea, and upon arrival in Korea the battalion was engaged in war as part of the 27th Commonwealth Brigade. The 25th Canadian Infantry Brigade sailed for Korea in April 1951 and came into the line towards the end of May. Upon arrival in Korea, the 25th Brigade was deployed as a unit of the newly established 1st Division of British Commonwealth.

In matters of military doctrine, the Canadian armed forces had much in common with the British armed forces, and unlike the Turkish soldiers the Canadian soldiers didnt have any communication problems at the Korean front. The 2nd Battalion of the Canadian forces played a big role in blocking the Chinese attack at the battle of Kapyong, demonstrating its excellent combat capabilities and its strong will to fight.
