The pure amount of seed companies out there can be overwhelming at times and we thought it was time to create a pretty sufficient list of trusted ORGANIC CANADIAN SEED COMPANIES BY PROVINCE.

As part of a sustainable and healthy lifestyle, seeking organic and local seed sources is one practice every gardener can do. Choosing organic seeds not only supports healthy ecosystems but also enhances the resilience of plants. Local seeds are better suited to regional climates, soil conditions, and pests.

The Importance of Organic & Heirloom Seeds


Organic seeds are grown without the use of synthetic fertilizers or pesticides. This practice contributes to healthier soil ecosystems and minimizes the harmful chemical residues that can affect food safety. Research shows that organic farming can reduce soil erosion by up to 16% and increase biodiversity, which is vital for maintaining ecological balance. Soil Health is a topic that can't be stressed often enough. Everything on planet earth literally relies on this natural underground ecosystem, also called the soil food web. From a wide variety of soil microbes, to organic matter, deep healthy plant roots and the supportive mycorrhiza - we can only grow enough food, if this fragile system is in tact. Conventional agricultural practices with its heavy machinery, monoculture, intensive use of fertilizers, herbicides, fungicides and pesticides damaged our soils tremendously. By 2050 about 90% of the world's topsoil will be at risk, according the to the UN Agriculture and Food Organization, FAO. Which translates to about 60 harvests that are being left! It's more than time to take soil more seriously and make soil regeneration a priority for everyone. By choosing organically produces seeds, you support companies taking the right steps towards soil regeneration and biodiversity support. It's literally in your hands.


Another fantastic aspect of organic seeds is that they often come from heirloom varieties that have been nurtured over generations, at least 50 years. These seeds not only provide superior flavor but are also better suited for specific local growing conditions. Heirloom crops are open-pollinated which makes them genetically more divers and adaptive to environmental conditions. They exceptional taste is another argument for heirlooms. For example, heirloom tomatoes can have 20% or more flavor than typical hybrid varieties, making them a favored choice among home gardeners and chefs. Another benefit of heirloom varieties is, that the home gardener can save his or her own seeds from these plants for their own usage.

Benefits of Local Seed Sources


Sourcing seeds locally offers several advantages for any gardener. Local seeds are adapted to specific soil types and climatic conditions, which means they often need fewer resources like water. In fact, studies have shown that locally adapted plants can be 30% more efficient in water usage compared to non-local varieties.


Moreover, purchasing seeds from regional suppliers strengthens the local economy and builds community ties among growers. This not only promotes a sustainable gardening culture but also enriches the agricultural landscape across Canada. Local agricultural organizations like the Eastern Ontario Agri-Food Network EOAN play an important role in connecting and educating local growers and consumers.
