Originally from Saint-Félicien, in the Lac-Saint-Jean region, Jean-Louis Lamontagne opened Chibougamau’s first grocery store in the early 1950s. In addition to feeding Chibougamau residents, the store was used as a place of worship and the first Masses were celebrated there by parish priest Marcel Vinette.

In 1969, Mr. Lamontagne co-founded company Provigo. Lamontagne street was named in his honour in 2013.
