William Dam Seeds established
William and Maria Dam start out at their kitchen table in Sarnia, Ontario.
A new home base
The family and seed business moves to our current home outside of Dundas Ontario.
Switch to exclusively untreated seed
William Dam decides to sell untreated seed due to a reaction he had to chemical treatments.
Organic seed is added to the catalogue
The first shipment of certified organic seed arrives in house from Italy in December 1999.
Are you ordering seed for next year?
If you are ordering seed for the 2021 gardening season please consider waiting till 2021. We encourage you to do this so that we can ship you freshly tested and packed seeds. While seed stored from previous seasons will most likely still germinate, vigor & germination may become erratic or decrease a bit. We always advise starting with fresh seed for best success.
Vegetables to sow for late season harvests
Why do we trial?
We maintain trial plots so that we can be familiar with the products we sell, try out new seed varieties against proven varieties, and understand the challenges sustainable production methods present such as insect control or weed suppression.
