OUR HISTORY
From a single lime plant in Québec, Canada, purchased more than 75 years ago to a global provider of essential calcium-based solutions, Graymont has supported the growth and development of vital industries for over three-quarters of a century.
Our Story Begins
Graymont began in 1948 with the purchase of a single lime plant in Marbleton, Québec—Dominion Lime Limited. Though modest by today’s standards, it marked the beginning of an extraordinary investment. Understanding where we are today begins with honouring the history that shaped our path.
