Highline Mushrooms Appoints New CEO

Company Press Release

Highline Produce Limited (“Highline”) is pleased to announce Aaron Hamer will succeed Glenn Martin as CEO, effective August 29, 2017. Highline will continue to benefit from Mr. Martin’s industry leadership and expertise as he assumes the role of Chairman.

Mr. Hamer is currently the CFO of Highline. He has been with Highline since 2014, guiding the growth strategy of the company through several mergers and acquisitions that have made Highline the world’s largest organic mushroom company with operations and customers across Canada and the United States. Mr. Hamer previously held the CFO role for a leading aerospace company and has experience working with private equity firms and publicly-traded businesses.

Highline has grown rapidly in recent years, thanks to the collaborative efforts of Mr. Martin and Mr. Hamer and their seasoned leadership team. Together, they have ensured Highline maintains its family-focused environment and fosters a positive and stable working environment for Highline’s associates.

“We thank Glenn for his incredibly successful tenure as CEO and are excited to partner with Aaron as he leads Highline through its next chapter,” reports Enda Walsh, Highline Board Member. “We are pleased that Glenn will assume the Chairmanship and look forward to his continued involvement with Highline.”

“Highline has been at the forefront of the mushroom industry’s innovation over the last 56 years, and we are thrilled with where we stand today,” says new CEO Aaron Hamer. “We are well positioned to keep growing ourselves, but more importantly, we focus on supporting our retail, food service and food ingredient customers in growing their mushroom categories.” Highline’s focus will remain unchanged: to continue to grow as a trusted leader in the North American mushroom market, but also as an employer of choice in the communities where we operate.


Highline Mushrooms, founded in 1961, has grown to become the largest mushroom grower in Canada and the world’s largest grower of organic mushrooms. Highline’s highly developed cropping techniques have enabled them to grow all white, mini bella and portabella mushrooms without the use of any pesticides or fungicides regularly required in the cultivation of mushrooms.

Highline is a fully integrated mushroom business with nine facilities in Ontario, Quebec, British Columbia and Alberta. It serves customers from the Atlantic Ocean to the Pacific Ocean and throughout both Canada and the United States.
