Growing Cannabis Seeds in Ontario

Growing top-shelf weed isn’t as easy as it looks.

However, the job of cultivating marijuana seeds is much easier once you understand the fundamentals of growing weed seeds. You’ll find all the answers below, from when to germinate cannabis seeds to what to watch out for.

When to Sprout Cannabis Seeds in Ontario

Ontario exhibits a humid continental climate.

In other words, the winters are long and cold, but the summers are hot and humid. Therefore, outdoor cannabis cultivators need to understand when to sprout their cannabis seeds.

Unless you want to see your marijuana seeds wither away due to frost — you’ll need to find the window of opportunity. In the case of Ontario — the best time to germinate marijuana seeds outdoors is at the beginning of May.

However, always check your local forecast to ensure optimal conditions. As global warming amplifies globally, average temperatures may shift higher or lower.

In any case, you should always grow fast-flowering seed strains from online seed banks to ensure a rapid harvest before poor weather arrives in the fall.

If you grow cannabis indoors — you can germinate weed seeds year-round.

Issues to Consider When Growing Marijuana Seeds in Ontario

Next, let’s take a look at everything that can go wrong during this year’s grow.

Although it’s not the most fun subject to talk about — it’s necessary. Here’s a list of problems that you may experience during this year’s cannabis season:

  • Law enforcement
  • Thieves
  • Inclement weather
  • Pests and diseases

As you can see — each of the elements poses a serious risk to your cannabis garden. Below, we’ll teach you how to prevent each issue from destroying your crop.

Law Enforcement

Although it’s completely legal to grow cannabis seeds and plants at home in Ontario — there are limits.

Overall, you must grow cannabis seeds or plants in a concealed environment — whether indoors or outdoors. Furthermore, you’re allowed to grow a maximum of four cannabis plants.

If you grow cannabis indoors, you must use a grow tent to prevent pungent odors and bright light from escaping. From carbon filters to grow lights, grow tents are the perfect choice for growing weed seeds and plants indoors.

If you grow marijuana outdoors, you need tall fencing to prevent passersby from noticing your garden. Remember, the police don’t mind weed gardens as long as you don’t flaunt them or go over the limit.


Although Ontario is one of the safest provinces in Canada — there’s still a high degree of theft.

Thieves understand that many residents in Ontario grow their own cannabis. Therefore, you need to protect your marijuana garden from getting robbed in the middle of the night.

If you grow indoors, your first line of defense is a top-rated security system. From surveillance cameras to motion-activated alarms, security systems are an excellent method for deterring thieves.

If you grow marijuana outdoors, high fencing and security lights are perfect for keeping thieves at bay. Additionally, outdoor surveillance cameras are excellent tools for preventing theft from your property.

Overall, you must follow the golden rule: never tell anyone that you grow cannabis seeds or plants. By doing so, you’re less likely to have a late-night visitor.

Inclement Weather

Although you can expect reliable growing conditions during the summer months in Ontario — you need to be ready for inclement weather.

As of recently, summer temperatures are becoming hotter due to global warming. Therefore, you need to plan ahead and buy drought-resistant seed strains from online seed banks.

Additionally, temperatures can suddenly shift as summer comes to an end. In other words, growing fast-flowering cannabis seeds is a must if you want to ensure a top-shelf harvest.

Pests and Diseases

Ontario is a humid province during the summer.

With constant humidity, you should expect pests and diseases. Therefore, it’s in your best interest to take a few pointers from our two-part IPM (insect pest management) guide.

First, always buy pest and disease-resistant seed strains from an online seed bank. By doing so, you’ll avoid a multitude of problems, such as bud rot or spider mites.

Second, always apply organic pesticides or fungicides 2-3 times during the vegetative phase. By doing so, you’ll prevent pests and diseases from gaining a foothold in your weed garden.

Tips for Growing Cannabis Seeds in Ontario

Now, let’s take a look at three tried-and-true tips for growing cannabis seeds in Ontario.

Buy Cannabis Seeds From a Reputable Online or Local Seed Bank in Ontario

First and foremost — always buy cannabis seeds from a trustworthy online seed bank.

Remember, you don’t want to throw your money away to a scam website or bogus seed strains. Therefore, finding a reputable seed bank is paramount when buying marijuana seeds in Ontario.

Seed banks are the gateway to thousands of verified seed strains, and it pays dividends to choose a high-ranking online seed bank. Once you’ve locked down the perfect online seed bank — make sure it ships to Ontario!

Buy Cannabis Seeds for Your Regional Climate in Ontario

Next, always buy cannabis seeds according to your local climate in Ontario.

Remember, Windsor is way hotter than Toronto, so you’ll need to have an idea of how hot or cold your region is. By understanding the weather pattern of your local climate — you can buy the perfect cannabis seeds from a seed bank.

Ultimately, buying cannabis seeds according to your local climate will ensure a stress-free growing season.

Plan Your Cannabis Garden in Advance

Last but not least is to plan your cannabis garden.

Even if your marijuana seeds from a seed bank arrive earlier than expected — don’t germinate them until the indoor or outdoor garden is set up. From trellises to grow light systems, ensure everything is ready for your incoming cannabis crop for the best results.

Which Marijuana Seed Store Is the Best Option For Residents in Ontario?

Next, let’s take a look at two different types of seed banks and which is the best option for residents in Ontario.

Local Cannabis Seed Stores in Ontario

Currently, residents in Ontario are limited in terms of seed selection.

The OCS (Ontario Cannabis Retail Corporation) is the primary vendor of all things cannabis. Although there are other licensed cannabis dispensaries — they are few and far between.

Therefore, buying cannabis seeds locally is a headache because it’s unlikely that you’ll find much of a selection. From unverified seed strains to high prices and a lack of availability — local seed banks are not the best choice.

In either case, here’s a list of local seed banks/dispensaries in Ontario:

  • Sessions Cannabis
  • Pop’s Cannabis

  • Canna Cabana

Ultimately, the best option for residents in Ontario to buy cannabis seeds is through the internet — online seed banks.

The History of Cannabis in Ontario

Now, let’s talk about the history of cannabis laws in Ontario.

Weed wasn’t always legal in Canada, let alone Ontario. Therefore, it’s good to understand what it took to legalize marijuana in the Heartland Province.

Cannabis Laws in Ontario

From cannabis prohibition to recreational cannabis, Ontario has come a long way from the heyday of outlawed weed.

Below, we’ll discuss all of the landmark moments that led to recreational cannabis in the Heartland Province.

Ontario Bans Cannabis

In 1923, Ontario, along with the rest of Canada, banned cannabis.

Remember, marijuana is not native to Canada, and most residents during the early days did not know what cannabis was. However, the government of Canada decided to outlaw marijuana before its southern neighbor — the United States.

Ontario Legalizes Medical Marijuana

Under a nationwide law, Canada legalized medical marijuana in 2001.

Therefore, medical marijuana became legal to patients once the Marihuana For Medical Purposes Regulations law went into effect. Under the law, residents in Ontario could become approved by doctors to gain a prescription for cannabis.

How to Obtain a Medical Marijuana Card in Ontario

If you want to become a legal medical marijuana patient in Ontario — you need to apply with Health Canada.

Once your application is accepted, you’ll have access to medical marijuana from government-run dispensaries throughout Ontario.

Ontario Legalizes Recreational Cannabis

In 2018, Canada became the second country in the world to legalize adult-use cannabis.

Although the Cannabis Act legalized cannabis across the country — each province created its own rules around the law. In this case, Ontario created a few stand-out rules for recreational cannabis participants:

  • Must be 19-years old or older
  • It’s legal to grow a maximum of four cannabis seeds or plants per household
  • The only legal locations to buy cannabis products is through government or private cannabis dispensaries
  • The public possession limit is 30-grams of weed
  • Private possession (at home) does not have a limit

The Legality of Cannabis Seeds and Seed Banks in Ontario

It’s legal to buy cannabis seeds from licensed seed banks in Ontario.

However, very few approved cannabis dispensaries sell marijuana seeds in Ontario, making it difficult to come across top-shelf seed strains. Luckily, it’s legal to buy marijuana seeds from online seed banks, such as MSNL Seed Bank or CKS, and have them shipped to your door in Ontario.

Penalties for Cannabis Possession in Ontario

Although recreational cannabis is legal in Ontario — you need to obey the rules set forth by the Cannabis Act.

Here’s a list of penalties associated with possessing marijuana in Ontario:

  • Possessing cannabis under the age of 19 is a violation
  • Possessing more than 30-grams of cannabis outside of a private residence is a crime

As you can see — there’s no real reason why residents in Ontario should be charged with a crime. Furthermore, residents in Ontario can possess unlimited quantities of weed at home.

Penalties for Cannabis Trafficking in Ontario

Remember, the government of Ontario (OCS) is the primary regulatory body for the cannabis industry in Ontario.

Unless the government of Ontario licenses you — it’s illegal to sell any amount of weed in the Heartland Province. Therefore, avoid selling any amount of marijuana at all costs.

The maximum penalty for selling cannabis in Ontario without a license is fourteen years in prison.

Penalties for Cannabis Seed Cultivation in Ontario

Overall, residents in Ontario are legally allowed to cultivate four cannabis seeds or plants at home.

Here’s a list of penalties associated with growing weed seeds or plants at home:

  • Growing more than four cannabis seeds or plants is a crime

Overall, it’s best to avoid breaking the law in Ontario. Remember, you’re allowed to grow as much weed as you want (in terms of weight) — but the plant count must remain at or below four.

Transporting Marijuana Seeds and Products Out of Ontario

The Cannabis Act in Canada is an agreement that allows the transportation of cannabis between provinces.

In other words, you’re allowed to fly between provinces with cannabis — as long as you understand the regulations of the province you’re landing in.

For example, if you fly to Quebec, you’re not allowed to possess weed or seed strains if you’re under the age of 21. Although you can possess cannabis at the age of 19 in Ontario, Quebec’s legal age limit is 21.

Therefore, always take a look at the laws of the province you intend to travel to.

Furthermore, it’s illegal to cross the border into the United States with cannabis. Even if you travel to a state that offers recreational cannabis — do not attempt to cross the border with any amount of marijuana.

Cannabis Culture in Ontario

Overall, cannabis culture is steadily growing in Ontario.

Thanks to the explosive growth of the cannabis industry, Ontario is witnessing a rise in the cannabis community. From B2B expos to cannabis awards, there’s always something for the cannabis community in Ontario.

Here’s a list of upcoming marijuana events in Ontario:

  • Lift and Co. Expo
  • The Karma Cup
  • O’Cannabiz

Ontario’s Booming Cannabis Industry

As of 2020, Ontario’s cannabis industry pulled in over $200 million in marijuana-related sales.

Since the Cannabis Act in 2018, Ontario has steadily become one of the premier provinces in Canada for cannabis. Ultimately, Ontario is expected to sell over $400 million by the end of 2021, making the cannabis industry a force to be reckoned with in the Heartland Province.

Ontario’s Illicit Market for Cannabis Seeds and Products

Even though cannabis is legal in Ontario (and the rest of Canada) — the illicit market is alive and well.

Many residents in Ontario buy cannabis from the illicit market because it’s untaxed. Overall, Ontario’s cannabis tax is relatively high at 13% (after duty tax). However, the tax revenue from Canada’s legal cannabis market is used for schools, infrastructure projects, social issues, and much more.

Furthermore, you’ll never know the real quality of cannabis products that you buy from the illicit market. Whether a seed or flower — it’s nearly impossible to gauge if the product in question is what the dealer says it is.

In other words, always buy cannabis seeds from online seed banks and marijuana products from licensed dispensaries. By doing so, you’ll avoid harmful chemicals and unverified seed strains.


Overall, Ontario is an incredible province to live in if you enjoy growing cannabis seeds at home.

If you’re ready to stock up on the best seeds that the cannabis industry has to offer — take a look at an online seed bank, such as MSNL Seed Bank or CKS. In either case, you’ll find cannabis seeds that have the potential to produce award-winning buds.

Don’t wait — the growing season is nearly here, and there’s no better time than now to get your cannabis garden off the ground in Ontario!
