Youth Bursary

There are opportunities to apply for a bursary. These are awarded to Thornhill students enrolled in full time post-secondary studies related to Horticulture and/or Environmental Sciences.

Community Service Volunteer Hours

We have many opportunities for high school students to volunteer as they gain their required community service hours:

  • Plant Sales Events: set up, selling, clean up

  • Community Improvement-gardening at our selected  sites

You'll be surprised how quickly you can accumulate your 40 hours and learn some new skills too!
