I am well aware of the conscription crisis, but in fact, only 25,000 conscripts made it to the front before the war was over according to Wikipedia (Conscription Crisis of 1917) whereas 619,636 Canadians enlisted in WW1 according to the Canadian War Museum, of whom 424,000 served overseas.  So as I said, the vast majority of Canadians were volunteers.  The population of Canada in 1914 was about 8 million, so that is exceedingly remarkable compared to other nations whose armies were mostly conscripts.  In fact, before the US entered the war in 1917, Canada had a standing army much larger than that of the United States, whose pre-war army was about 98,000 men plus 27,000 National Guardsmen.
