Keeping Ontario Beautiful Together


Share your love for gardening…


Your donation provides tree grants and helps fund community projects across Ontario to promote the importance of gardening in protecting our part of the world.

Our Top Priorities


We promote the careful use of our natural resources to prevent them from being lost or wasted.


How do we take care of those we love and where we live? By planting a pollinator garden of course!


Gardening benefits people and communities and brings them together. Look through our resources, events, and join us on Facebook. Say hello.


The involvement of today’s young people in all areas of horticulture is crucial. Shortly, Ontario will be theirs to care for.

Last year we had over 28,000 members in 273 societies and 19 districts throughout Ontario. We have seen a lot of change in that time but gardening remains a passion that provides food for our families and beauty in our communities.

You can help us do more this year…

Planned Legacy Giving


Tax Efficiency

Clients will receive an immediate tax receipt for their donation. Unused credits may be carried forward for up to 5 years. No capital gains taxes are realized on gifts of long-term appreciated publicly-listed stocks, bonds and mutual funds.

Low Cost Alternative

Compared with the expense of setting up and maintaining a private foundation, the Planned Legacy Giving Program is an inexpensive way to manage a sizeable gift.


Clients may recommend grants to any number of charities or other institutions each year, with minimum grants of $250.


The Planned Legacy Giving Program simplifies the charitable giving experience by handling administrative tasks (i.e. issuing cheques, record-keeping, grant reporting and tax receipts) for each account.

Make a difference today. Speak to your financial advisor to learn more about the benefits of the Planned Legacy Giving Program to the Ontario Horticultural Association.

The OHA is all about sharing a love of gardening that can be enjoyed all year long. Learning how to grow food in small spaces, a community garden, or in containers is very important. We are a charitable organization and we only receive dues from our societies and, if we are fortunate, donations from generous people like you.

Won’t you join us; together we can bring gardening to communities across Ontario.

- OHA Past President, Katharine Smyth
