I was reading the WWI file of the husband of a distant relative of mine. He was stationed in Montreal at the end of the war, and was part of the military police. In an incident, he approached a soldier who was drunk and disorderly. When he told the man to straighten up, the man refused and used "very bad language, and called me a conscript". At this point the M.P. tried to arrest the man, and they got in a fight, resulting in the M.P. getting kicked in the eye and being knocked out.
I just found it interesting that in his testimony of the incident, he specifically notes that the drunk soldier "called me a conscript". Was this really a low blow to conscripted soldiers?
It's hard to know without more context and background on the individual soldiers, but the Conscription Crisis in 1917 was a firestorm in Canadian politics. French-Canadians by and large opposed conscription (among others, but I'm using the context of this happening in Montreal), while others supported it vehemently since volunteer numbers were dwindling. It was approved in August 1917, but not without furthering tensions. Attempts to arrest draft dodgers even resulted in fights in the streets in 1918. Those who supported conscription framed the French-Canadians as cowards. You can read a bit more on the Canadian War Museum's website where they also have primary sources about the issue: https://www.warmuseum.ca/firstworldwar/history/life-at-home-during-the-war/recruitment-and-conscription/conscription-1917/ and there's another one here that has some interesting primary source quotes about soldier experiences here: http://ww1.canada.com/home-front/quebecs-conscription-crisis-divided-french-and-english-canada
