Why was Canada’s war declaration on Nazi Germany (on September 10th 1939) important?
Since World War I 1 Canada was its own country. This meant it also had to represent itself as a own country for example taking actions against a state of Germany which is killing and conquering a big part of central Europe. Canada also what’s to be recognized as a powerful country, maybe declaring war wants the biggest threat to Germany, but it send a message to the Wold that Canada can handle its own.
