U of G appoints Dr. John Cranfield Dean of Ontario Agricultural College

Mar 07, 2025

Dr. John Cranfield, a respected and long-standing member of the University of Guelph’s faculty, has been named the new dean of the Ontario Agricultural College (OAC). Cranfield, who has led the college as interim and acting dean since July, 2023, began the five-year appointment March 1, 2025.

As dean, Cranfield’s focus will be to elevate OAC’s local strength, national leadership, and global impact in food, agriculture, communities and the environment.

“OAC is truly an incredible place,” says Cranfield. “As I led OAC during its 150th anniversary last year, I was reminded of the college’s storied legacy and enduring relevance in addressing global challenges in food, agriculture, rural communities and the environment. I am honoured to continue advancing this legacy.”

Cranfield’s journey at U of G started as a student, having earned his MSc and BSc from U of G in agricultural economics. After obtaining his PhD from Purdue University, Cranfield briefly taught at the University of Manitoba before returning to Guelph in 2001.

Ask Canada’s most decorated soybean breeder his favourite part of the job and he doesn’t name a single variety. He names the students.

Istvan Rajcan is a professor of soybean breeding and genetics in the Department of Plant Agriculture at the University of Guelph, where he has run the soybean breeding program for 28 and a half years. In that time he has developed 87 soybean cultivars, published 140 refereed papers and trained 51 graduate students. In 2025 he received the Public Sector Impact Award from the National Association for Plant Breeding.

He is also worried. In this episode he says Canada is at a crossroads, pointing to recent government cuts to plant breeding programs and to the facilities that support them. His prescription is structural. "Plant breeding funding formula has to be a long-term one," he says.

The formula he is defending is the public-private matching arrangement his program runs on. Private seed companies fund the work, provincial or federal money matches it, and the combined pool stretches each dollar further than either source could alone. At the National Association for Plant Breeding annual meeting in June, he says American public breeders were often surprised at how well that collaboration works in Canada.

He also describes how the people entering plant breeding have changed. His early graduate students came mostly from farms. More recently they include, in his words, "city kids who just became excited about genetics."

Why public-private plant breeding funding in Canada needs a long-term

commitment rather than a larger one

How matching private seed company investment with provincial and federal

dollars multiplies research capacity
