An Extensive List Of The Top Seed Providers In Canada (& The U.S.) 2025 Edition

Wondering where to get the best seeds for growing veggies, herbs, flowers and fruit in Canada? These are the trusted and loved 50+ best seed suppliers to buy from in Canada in 2025. Plus, I’ve thrown in a few of the best American-based seed companies you can order from online.

Seed ordering is happening earlier and earlier each season with many gardeners now ordering their seeds as early as November-December. Crazy, right?

The demand for seed orders boomed after the pandemic saw more people at home turning to gardening as a hobby. I love to see it!

But it does mean you should ideally get your seed orders in earlier. Or, some varieties you want to get your hands on will likely be sold out.

Not to worry — it could also be an opportunity to diversify your garden and try new things.

Plus, be mindful to not “over-order.” Leave seeds for other gardeners too. There’s lots to go around.

40+ Best Seed Supplies in Canada in 2025

It’s safe to say, Canada has some fantastic, trusted seed providers across the country.

This list includes both small, locally-operated seed companies as well as some of the major players too.

Pro Tip: Sign up to receive FREE seed catalogues!

Nearly all seed providers send out a beautiful, FREE seed catalogue each Winter (usually around Christmas time).

These catalogues detail all the varieties they are offering for the upcoming season. It’s a great way to get inspiration for the garden, see what’s new and popular and to just daydream about warmer days ahead.

Did I mention the catalogues are free?

These Canadian seed suppliers are rated top overall based on:

• Available varieties
• Organic certification
• Seed germination rates

1. West Coast Seeds – based in B.C.

There’s SO MUCH to love about this seed supplier. West Coast Seeds offers thousands of non-GMO, organic vegetable, flower and herb seeds.

They are 100% committed to ethical growing and have extremely fast shipping across North America.

I always find new and unusual varieties at West Coast Seeds that other suppliers don’t carry — like chickpeas, hops and quinoa!

2. Veseys Seeds – based in Prince Edward Island

Veseys is a long-time seed provider, operating for over 80 years on the small eastern island of PEI.

Their seeds are reliable with nearly 100% germination rates (from my experience).

Plus they have many varieties that are bred for market gardeners, providing high yields and uniform vegetables/fruits.

I personally love ordering my flower bulbs from Veseys in the Spring. They have a large selection!

William Dam is a family-owned seed company that’s been around for more than 60 years. They have a great selection of unique veggie, flower & herb seeds.

OSC (Ontario Seed Company) is the largest Canadian owned and operated packet seed company.

They don’t have as many organic varieties to choose from as some of their Canadian competitors, but they do have an interesting assortment of heirloom seeds.

So if you are a Zone 3, Zone 2 or colder gardener, you can trust OSC Seeds to succeed in your garden.

5. Sage Garden Greenhouses – based in Manitoba

This small seed supplier and nursery might come as a surprise to you that it makes my top 5 list.
