Toronto Master Gardeners are volunteers whose mandate is to share current, science-based horticultural information with the gardening public: in person, in print, via media, and online. Prior to becoming a Toronto Master Gardener, the successful recruit participates in the 2–3-year prerequisite Toronto Master Gardener-in-Training program. During this internship, the Toronto Master Gardeners-in-Training (MGiT) are mentored by an experienced Toronto Master Gardener and supported by the Recruitment and Training Team. You may be advised of other Master Gardener groups you can join if your residence is not in Toronto.

Thank you to all those who expressed an interest in the program and submitted an application to become a Toronto Master Gardener-in-training for 2023. The application and intake process is now closed.

Our next application and intake process for the Toronto Master Gardener-in-trainees will begin in August 2023.

If you would like more information about the Master Gardener program and to understand if becoming a Master Gardener is right for you, please send a message to and we will get back to you. Thank you.

The Toronto Master Gardeners is an organization committed to fostering an environment in which everyone we engage with, including fellow members and the general public is treated with dignity and respect, regardless of race, national and ethnic origin, colour, age, gender, sexual identity or sexual orientation, religion, political affiliation or abilities.
