Jersey Canada Extension Representatives provide farm-level support to Jersey Canada members and Jersey breeders across the country. In collaboration with Jersey Ontario and Jersey Quebec, and in contract with Holstein Canada to serve Western and Eastern Canada, seven extension representatives are available to anyone interested in Jerseys, or those that already have Jerseys in their herd. Friendly and knowledgeable reps will provide on-farm assistance and tools to help producers achieve their business goals.

This program’s main purpose is to encourage and facilitate use of services offered by Jersey Canada, and animal improvement services offered by industry partners. This initiative also includes elements of mentorship and education. Input can be provided on management of Jerseys, breeding topics, nutrition, dairy education outreach at agricultural schools, or connecting breeders to outside resources to help achieve individual goals.

If you are interested in learning more about this program or would like to contact an extension representative in your area, please contact the Jersey Canada office at info@jerseycanada.com.

Toby Kleinsasser

Western Extension Representative
(519) 865-4367

Toby was contracted by Jersey Canada through Holstein Canada as our Western Extension Representative in late 2021.

"I have been involved in the Ag industry for as long as I can remember. From a young kid working with my dad in the dairy barn, then in the hog farrow to finish operation as well the cropping side of the farm. I worked for a breeder around Coaldale AB close to six years, where I also became involved in 4H as well as Team AB WCC. After a year with DHI, I spent the past three years working in a mixed animal veterinary clinic, as well as doing relief evenings and weekend milking. I enjoy working in the field and meeting the people that make the dairy industry as great."


Darren Isaac

Western Extension Representative

"I have always been fascinated by animals of all kinds. I have worked with various species of livestock, including over 4 years as a herd manager at a Manitoba dairy. With my role as classifier and field service at Holstein Canada, I'm excited to help breeders improve their cattle at a herd and breed level. I value functional conformation and profitability and using services and information to maximize cow performance on farm. I love discussing genetics and breeding programs."
