Highline Mushrooms is a family company, founded in 1961 by Dr. Murray O’Neil. We have four growing facilities (two in Leamington, Ontario, one in Kingsville, Ontario, and one in Wellington, Ontario) and a distribution center based in Montreal, Quebec. From humble beginnings, we have grown to become the largest independently owned and operated mushroom growers in Canada. We can attribute this to a number of factors; however, there are three fundamental principles that have guided us throughout the years:

Focus on Excellence – “First we will be best, then we will be first.” – Dr. Murray O’Neil

Associate Care – we are a family business and every Associate is a member of our family

Customer Service – our customers deserve the very best from us

With a passion for quality and innovation, Highline has driven to the forefront of many great technological advances in the North American mushroom industry. Our highly developed cropping techniques have enabled us to grow all white, mini bella and portabella mushrooms without the use of any pesticides or fungicides regularly required in the cultivation of mushrooms.
