The Dominion Brick Company Limited was a manufacturer of building materials operating in the region of Sainte-Thérèse de Blainville, north of Montreal. This certificate No. 31, issued in 1913 in the name of Anthime Desjardins, is one of the earliest numbers in the series, indicating a founding issue or a very early transaction in the company's life. The brick industry experienced strong demand at the beginning of the 20th century, driven by the boom in residential and industrial construction in Canadian cities. Anthime Desjardins appears to have been a local investor active in several regional Quebec companies. This document perfectly illustrates the local economic fabric of the Montreal region during Canada's Belle Époque.
