Between 1900 and 1910, Saint-Lambert Street was all in a fervour, thanks to Onésime Lambert who bought everything in town that was located east of Laval Street from the Royal Mills Company. He then became rich through real estate speculation when Bromptonville’s population increased rapidly.
In September 1901, it was Berthus Dion’s turn to do business with him. He had just been married at the Sainte-Praxède Church and decided to settle his family and business on Saint-Lambert Street: his family at number 56 and his business, a bakery, at number 58. Note that, at the time these were adjoining lots, Sainte-Praxède Street did not yet exist.
Berthus Dion passed away on May 2, 1960, at the age of 77. His children held onto the bakery for a few more years before selling it to Ulric Allard. At the end of the 1970s, the building lost its commercial vocation and became a dwelling.
