Français There is no single best cannabis seed bank in Canada — there is a best one for what you are growing. The honest answer depends on three things: whether you grow indoors or outdoors, whether your season is short, and whether you want one breeder's own genetics or a catalogue of many breeders. Below is how to decide, with our own answers filled in so you can hold us to them.
The short answer
| If you are… | What matters most | Where QCS stands |
| Growing outdoors in Quebec, Ontario or the Prairies | Outdoor harvest dates, not just indoor flowering times | Strong fit. Our outdoor seeds are grouped by harvest month; September finishers suit short seasons. |
| Growing indoors, any province | Stable genetics and an honest germination guarantee | Good fit. 80% germination guarantee with replacement seeds. |
| Wanting the widest possible catalogue | Breadth across many breeders | Weaker fit. We are a breeder, not a reseller, so our catalogue is deliberately narrower. |
| Hunting a specific imported strain | Access to international breeders | Weaker fit. A multi-breeder reseller will serve you better. |
| Ordering in bulk | Price per seed and pack sizes | Good fit. Bulk packs available; compare per seed, not per pack. |
| In the USA | Customs risk and delivery speed | Good fit. 1 to 2 business days by Express, delivery guaranteed. |
A note on the numbers in this article: harvest dates, flowering times and yields are ranges, not promises. They vary depending on growing conditions: the grower, the method and the season's weather. "Mold resistant" means mold tolerant: less prone to mold and slower to be affected. No strain is 100% mold resistant. How we set these numbers →
Who Canadians usually compare
The seed banks that come up most often alongside us are Crop King Seeds, True North Seed Bank, Sunwest Genetics, Beaver Seeds, Rocket Seeds and MJ Seeds Canada. All of them ship within Canada. We are not going to put words in their mouths about their guarantees or delivery times — those change, and you should read them yourself on the day you order.
What we will give you is the list of things worth checking, and exactly what we put in writing. Run the same seven checks on any seed bank you are considering, including this one.
A good seed bank puts its guarantees in writing, ships from where it says it does, and can tell you where its genetics come from. Compare the seven points below before you order. For each one, we give our own answer so you can hold us to it.
Before you order
7 things to compare between cannabis seed banks
A good seed bank puts its guarantees in writing and can tell you where its genetics come from.

1. The germination guarantee
Look for a stated percentage and a stated remedy. "High germination rates" is not a guarantee.
Our answer: we send replacement seeds if germination is below 80%.
2. The delivery guarantee
Ask what happens if the package never arrives.
Our answer: we guarantee delivery of your order.
3. Where the seeds ship from
Seeds shipped from inside Canada do not cross a border to reach a Canadian address. Check the seed bank's shipping page for the origin, the carrier and the delivery time.
Our answer: we ship from Quebec, usually the same day or within 24 hours of payment, Monday to Friday. Delivery in Canada takes 3 to 7 days, or 2 to 3 days by Express. Orders over $200 ship free.
4. The packaging
Packaging should protect the seeds and say nothing about what is inside.
Our answer: plain, unbranded packaging with no logos and no mention of the contents. No signature is required.
5. Where the genetics come from
Some seed banks breed their own strains. Others resell seeds from several breeders. Both can be fine, but you should be able to tell which you are buying. Look for the parent strains on each product page and for a page that explains the breeding.
Our answer: QCS has bred and selected seeds in Quebec since 2015, led by a grower with more than 35 years of experience. Each product page lists the strain's genetics. Read about our breeding program and our strains bred in Quebec.
6. Whether the strains suit your climate
This matters most for outdoor growers. A strain that finishes in late October in California may never ripen in Quebec. A seed bank that knows the Canadian season will give outdoor harvest dates, not only indoor flowering times.
Our answer: our outdoor seeds are grouped by harvest month. For Canada and other northern climates, a September harvest strain is the best choice.
7. Privacy and support
Read the privacy policy for one sentence: whether your information is sold or shared. Then check that there is a phone number and that someone answers it.
Our answer: we do not sell or share your information with third parties. You can reach us at 514-805-2741, Monday to Friday, 11 AM to 6 PM EST.

Buyer’s tip
Compare the price per seed, not per pack
Pack sizes differ from one seed bank to the next. Divide the price by the number of seeds, then add shipping and check the free-shipping threshold.
Common questions
How do I compare prices between seed banks? Compare the price per seed, not per pack, because pack sizes differ. Most of our packs contain 5 seeds. Add the shipping cost and check the free-shipping threshold.
Is the biggest catalogue the best? Not always. A smaller catalogue that suits your climate is more useful than a large one that does not.

When Quebec Cannabis Seeds is not your best choice
Three cases where we would point you elsewhere:
- You want a specific imported strain we do not breed. We are a breeder with our own line, not a catalogue of everyone else's work. If you have your heart set on a particular European or Californian release, a multi-breeder reseller is the right shop.
- You want the largest selection you can find. Our range is deliberately narrower and weighted toward what finishes in a Canadian season. If breadth is your priority, we are not it.
- You need regular seeds rather than feminized. Most of what we sell is feminized or autoflowering. If you are breeding and need males, look for a bank with a dedicated regular-seed range.
Where we are hard to beat is the Canadian outdoor season. Seeds bred in Quebec, selected since 2015 under a grower with more than 35 years of experience, grouped by outdoor harvest month, and shipped from inside Canada so nothing crosses a border to reach a Canadian address.
Frequently asked questions
What is the best cannabis seed bank in Canada?
It depends on what you are growing. For outdoor growing in a short Canadian season, choose a bank that publishes outdoor harvest dates and breeds for northern climates. For a specific imported strain, choose a multi-breeder reseller. Run the seven checks above on any bank before you order.
How do I know a Canadian seed bank is legitimate?
Four signs: a germination guarantee with an actual percentage and a stated remedy, a delivery guarantee, a shipping page naming where the seeds ship from and how long they take, and a phone number that a person answers. Vague phrases like "high germination rates" are not guarantees.
Are seeds shipped from inside Canada better?
For a Canadian address, yes, because nothing crosses a border. Seeds shipped from overseas can be delayed or seized at customs. Check the seed bank's shipping page for the origin rather than assuming a .ca domain means domestic.
How do I compare prices between seed banks?
Divide the price by the number of seeds, not the pack. Pack sizes differ, so a cheaper-looking pack is often more per seed. Then add shipping and check the free-shipping threshold. Most of our packs are 5 seeds, and shipping is free over $200.
Does a bigger catalogue mean a better seed bank?
No. A small catalogue suited to your climate beats a large one that is not. For outdoor growing in Canada, a dozen strains that finish in September are worth more than a thousand that finish in November.
What germination guarantee should I expect?
A specific percentage and a stated remedy. Ours is 80%: if fewer than 80% of your seeds germinate, we send replacements. Anything without a number attached is marketing, not a guarantee.
Which seed bank is best for growing outdoors in Quebec?
Choose one that lists outdoor harvest months rather than only indoor flowering times, and favour September finishers. A strain that finishes in late October in California may never ripen in Quebec.
Do Canadian seed banks ship to the USA?
Many do, including us. We ship to the USA by Express in 1 to 2 business days with delivery guaranteed. Check whether the bank guarantees delivery or merely dispatch.
