Although individual seeds of the same species are remarkably similar to each other, seeds from different species vary considerably in size and weight. This makes it impractical to define a “standard” packet across the wide range of species we offer.
When it comes to generic row crop vegetable seeds, we fill the packet with enough seeds to sow a typical householder’s garden row of 3-3.7 m (10 to 12 feet). We do offer select varieties in seed packets where we have counted the seeds.
If you are interested in more detail regarding seed counts per packet for any of the species we offer, please contact us or call us at 519-886-0557.
Yes, many of our varieties are available in bulk packages. This information is available in our online and paper catalogues.
The majority of our seeds are packaged by machine. Some specialty varieties are machine counted and packaged.
For all our vegetable seeds, you will see a line that states the number of ‘seeds per gram’ for that variety. Most bulk packages are sold by weight.
The ‘seed per gram’ measurement is an approximation, so please keep in mind that as seeds age they gradually lose moisture and this can affect the package weight.
Some hybrid varieties are sold by the seed count and this information is stated in our paper and online catalogues.
We purchase our seed from growers around the globe.
With the exception of a few varieties of corn for commercial growers. We do not offer treated corn for sale on our website. Please contact OSC directly if you are looking for treated corn seed. Our treated corn is coated with a mild fungicide and is clearly-labelled to avoid confusion.

The most important difference between organic and standard seed are the systems that produced them.
In Canada, there is a federally-regulated organic standard.
Canadian organic standards aim to ensure that all aspects of farming are conducted in a way that promotes the overall health of soil, plants, animals, humans, and the planet. Organic practices use a proactive, rather than a reactive approach to farming, minimizing or avoiding expected problems in the farm system. The health of the land is prioritized. Potentially harmful inputs are restricted or forbidden.
Ontario Seed Company is organic in two ways:
Firstly, we have a line of certified organic seed. This means the seed itself is certified organic and has been produced by a certified organic system (yay!)
Secondly, we are a certified organic processor. This qualifies us to package and distribute certified organic seed, ensuring its organic integrity is never compromised.
Look for this logo to be sure Canadian organic standards have been met:
Copies of our organic certificates can be found on our website or by clicking here.
If you believe a brand is making false claims about being organic please contact the Canadian Food Inspection Agency.

Genetically Modified Organisms [GMOs] are created by a laboratory process where genes from one species are extracted and artificially forced into the genome of a plant species with which they would normally be incapable of exchanging genes.
Hybrid varieties are created when humans use selective pollination to cross different varieties and species. Hybridization occurs naturally (cross-pollination) but seeds that are advertised as hybrids were deliberately crossed to express certain traits. Common ones are disease resistance, size, colour, and cold hardiness.
Seeds saved from hybrid plants may revert to the stronger of the “parent” genes, instead of reproducing exactly as they were.
Excessive plant growth has been a shared experience by many Canadian growers this year, making this a very Frequently Asked Question in 2019! Some years, Mother Nature serves up the perfect conditions for massive growth. Just like dim, cool, dry weather can slow growth, things like too much rain and sun can stress plants into growing bigger and taller than usual. That has certainly been the case for the 2019 growing season throughout much of Canada.
What if the weather does not seem to be the cause?
- Reduce fertilizers- especially nitrogen: Put simply, Nitrogen is the nutrient responsible for green growth. Excess nitrogen can cause excess green growth and even make vegetable crops so focused on green growth that they neglect to produce vegetables!
- Improve lighting: Plants that are not getting enough sunlight will “reach” for more light and become tall and slim, or “leggy.” Check that you are meeting the minimum light requirements for each individual variety in your garden. Move sun-starved plants to a new location in the garden or trim low-hanging branches of nearby trees to invite more sun.
- Amend soil: If you have not fertilized and the weather does not seem to be the cause, test your soil to determine whether there is a nutrient imbalance. Your local garden centre or nursery can help you choose a soil sample kit and recommend the best products to amend your soil.
