Area Code 579 is an overlay to 450 in the greater Montreal region, introduced in 2010. As suburbs swelled and businesses multiplied, 579 became a natural extension of a fast-growing corridor. From tech firms in Laval to family-run bakeries in Longueuil, 579 reflects a region where diversity and development go hand in hand. It doesn’t carry the weight of 514, but it’s practical, present, and unmistakably local. In Quebec’s suburban belt, 579 is what modern life sounds like. It’s not about status, it’s about connection.
