The regiment left Ottawa on August, 28 and boarded the SS "Megantic" in Montreal, Quebec. However, because of enemy action in the Atlantic Ocean, the regiment had to deboard at Lévis, Quebec. During the period of Training at Lévis, following extensive tests on the Ross rifle, the Patricias issued the first of what would be many damning reports of the suitability of the Ross rifle for combat. The regiment finally left on September, 27 from Quebec City on board the "Royal George" for England in company with the rest of the first Canadian contingent.
