Highline Mushrooms was founded in 1961 in Leamington, Ontario as a small family farm. Founder Dr. Murray O’Neil set the bar for a focus on family values, excellence, innovation and work ethic. Since then, Highland has grown to be the world’s largest grower of organic mushrooms – and one of the largest mushroom growers in North America, shipping to Canada, the U.S. and Japan. Highline’s commitment to quality, sustainability and innovation delivers one of nature’s most-perfect superfoods to tables around the world.
