Lanthier Bakery was founded in Alexandria, Ontario, by Georges and Adrienne Lanthier in 1932.  As one of four new bakeries in the small town of Alexandria, considering that bread was mainly produced in the home, the challenges were many. Initially, all customers were served door to door and were offered a variety of fresh bread and pastries.

Over 150 people ultimately became employed in production, sales and administration as the bakery grew. In 1985, a second production facility was built in Montreal to satisfy the ever increasing demand. Soon the sole focus became bread made with traditional recipes using the sponge and dough method.

Today, Lanthier Bakery is still owned and managed by the Lanthier family, and is now one of the largest independently owned commercial bakeries in eastern Canada. Lanthier Bakery enjoys continued success, growth and independence.
