What date did Canada enter World War 1?

Answer 1

On 4 August 1914 Britain declared war on behalf of the whole British Empire.

It was actually on 5 August. The Germans entered Belgium on 4 August. Belgiums neutrality was guaranteed by a treaty signed by France, Britain and Germany and although Germany didn't believe that Britain and France wouldn't mind if Belgium was attacked ... they did! Great Britain declared war on 5 Aug on behalf of the entire British Empire.

On August 5, 1914, the Governor General of Canada, after being Directed by The Parliament of Canada Declared a war between Canada and Germany.

Answer 2

Canada was a colony of Great Britain, who was a part of the Triple-Entente.

When the First World War started, Austria-Hungary wanted to punish Serbia for one of it's people in a terrorist group called the Black Hand for assassinating their heir to the throne, Archduke Franz Fernidad, and his wife, Sophia, while they were on a visit to Serbia. Since Serbia was allied with Russia, Russia began to mobilize it's army to protect it. Germany saw this as a threat, and then declared war on Russia. As part of the Triple-Entente, Britain and France declared war on Germany, and by extension, Canada did too.
