Introducing OMAFA’s New Entomologist (Horticulture), Dr. Jason Lemay

With the retirement of OMAFA’s Entomologist for horticulture crops of 25 years, Hannah Fraser in May 2026, we are excited to welcome Dr. Jason Lemay to the position.

Jason has a broad background with experience in many different horticulture crops. He completed his MSc at the University of Guelph where he conducted research on integrated pest management (IPM) for insect pests of carrots in the Holland Marsh (MSc).

He then spent a few years as an IPM consultant, working with greenhouse floriculture and vegetable growers as well as ornamental nurseries before returning to the University of Guelph to do his PhD. His PhD research focused on IPM for insect pests in cannabis.

Recently, he was the OMAFA Fruit Crop Specialist (Acting) for berries. Prior to that, Jason was working at Ontario Soil and Crop Improvement Association in the Programs Department assisting in the delivery of cost-share funding programs.

Jason enjoys working with growers to develop practical solutions, and support innovation in the horticultural sector.

We welcome Jason to the OMAFA Apple Team!
