Can you buy cannabis seeds legally in Ontario? Adults 19 and older may purchase legal cannabis products from the Ontario Cannabis Store or an authorized private retailer. Ontario residents may grow up to four cannabis plants per residence—not per adult—for personal use, provided the seeds or plants come from an authorized source and other applicable rules are followed.

Cannabis seed types
Autoflower vs. feminized vs. regular seeds
| Seed type | How it grows | Good fit for |
|---|---|---|
| Autoflower | Begins flowering primarily with age rather than a strict light-cycle change | Shorter timelines and compact spaces |
| Feminized | Bred to produce predominantly female plants | Growers who want to reduce the likelihood of male plants |
| Regular | Can produce male or female plants | Experienced growers and breeding projects |
No seed type guarantees germination, sex, yield, potency or harvest timing. Outcomes depend on genetics, environment and cultivation practices.
How to choose weed seeds
- Know your space: consider indoor versus outdoor growing, plant height and available light.
- Check the seed type: autoflower, feminized and regular seeds require different planning.
- Review timing: breeder estimates are guidance, not guaranteed harvest dates.
- Plan for Ontario’s limit: the limit is four plants per residence, not four plants per person.
- Buy from an authorized retailer: legal sourcing matters even when seeds are sold online.

Frequently asked questions
Cannabis Seeds Canada FAQs
Where can I buy legal cannabis seeds in Ontario?
Adults 19 and older can buy legal cannabis seeds through the Ontario Cannabis Store or an AGCO-authorized cannabis retailer such as Montrose Cannabis. Availability depends on current regulated inventory.
Can Montrose ship cannabis seeds anywhere in Canada?
This page serves customers through Montrose’s authorized Ontario recreational retail channel. Delivery and pickup depend on your Ontario location, age verification and current service availability. We do not present recreational seed sales as nationwide shipping.
How many cannabis plants can I grow in Ontario?
Ontario generally permits adults 19 and older to grow up to four cannabis plants per residence for personal use from legal seeds or plants. The limit applies per residence, not per adult. Other housing, municipal or property rules may also apply.
What are autoflower cannabis seeds?
Autoflower genetics begin flowering mainly according to plant age rather than requiring the grower to change to a particular light schedule. Actual growth time, size and yield vary.
What are feminized cannabis seeds?
Feminized seeds are bred to produce predominantly female plants. They reduce—but do not eliminate—uncertainty, and no retailer can guarantee the sex, germination or performance of every seed.
Are regular cannabis seeds suitable for beginners?
Regular seeds can produce male or female plants, so growers need to identify and manage plant sex. They may be better suited to experienced growers or breeding projects.
Are cannabis seeds guaranteed to germinate?
No. Germination and plant performance depend on seed condition, storage, handling and growing conditions. Review the product information and applicable return policy before ordering.
Is Montrose a Canadian cannabis seed bank?
Montrose is an authorized Ontario cannabis retailer carrying regulated seed products from licensed producers. It is more accurate to describe the store as a legal retailer than as a traditional unregulated seed bank.
