- July 24 – Workers began an illegal strike at the Alcan aluminum complex at Arvida, Quebec, when 700 workers walk off the job. Some 4,500 workers occupy the factory the next day. Minister of Munitions and Supply C.D. Howe says that enemy sabotage was responsible for the work stoppage, and soldiers are sent to secure the facility. Work resumes on July 29 as workers and management negotiate, assisted by federal conciliators. A subsequent royal commission rejects the sabotage theory and finds that the strike was the result of worker dissatisfaction with wages and working conditions, as well as a heat wave that occurred immediately before the strike.Canadasource
