About Us

The Thornhill Garden & Horticultural Society's members have a common interest in gardening and the greening of our homes and community through horticultural activities.

Organic Garden
Sponsored Thornhill FRONT Garden Recognition Program

356 Signs Placed in 2023!

Each year our team

makes its way

through the streets

of Thornhill looking for

beautiful front gardens

with great curb appeal that enhance our community. We placed recognition signs in over three hundred and fifty gardens! This year Board Members worked independently to keep everyone safe!

Thanks to Realtor  Paul Zammit for sponsoring our signs.

People often ask,

"How can I get one?"

To be considered, Thornhill residents can self-nominate, or nominate other front gardens by emailing: with the address(es).

Nominations for 2024 close on June 25th!


Nominations do not guarantee a sign. Gardens are assessed on the day of visit.

Signs are awarded the end of June/early July depending on the weather.

Late summer we retrieve the signs and store them for use the following year.

Our Society promotes the beautification of Thornhill's public and private spaces by:​


Planting and maintaining trees, plants, shrubs and flowers at several community locations including:

  • Bayview/John Garden (southwest corner of Bayview Ave. and John St.)

  • Percy Bone Parkette (located in Thornhill Park)

  • Richard A. Jarrell Memorial Garden at the Thornhill Village Library

  • Alzheimer Society of York Region Magna Sensory Garden (10 Harlech Ct.)

Our Society's members continue to pursue activities and programmes which ensure that we remain relevant and resourceful in an ever-changing time and climate.

We are proud to carry on the vision a few gardeners had in 1914 - that of a Horticultural Society which would promote, and contribute to the beautification of the Thornhill community.
