Adults in Canada can grow up to four cannabis plants per household under the federal Cannabis Act, but the provinces set extra rules: Quebec bans home growing completely, Manitoba allows four plants indoors only, and several provinces control where plants can be seen.
Last updated: October 2026
The four-plant rule is simple on paper and easy to get wrong in practice. It counts plants per home, not per person, and it applies to every plant in the house, from a week-old seedling to a plant drying on a hanger in October. Your province can also add rules about age, visibility, locks and fences.
This guide sets out the federal limit, a province and territory table for 2026, what counts toward the four, and how to plan a grow so that four plants still give you a worthwhile harvest. It is general information, not legal advice, so check your provincial page and your local bylaws before you plant.
How many cannabis plants can you legally grow in Canada?
You can legally grow up to four cannabis plants per household at any one time, as long as you are of legal age in your province and your province allows home growing. The rule comes from the federal Cannabis Act, which took effect on 17 October 2018, and it is the same number whether one adult or five adults live in the home.
The limit applies to the residence, not to each person. Two roommates cannot grow eight plants, and one person cannot grow four plants at home and four more at a cottage they also use. The Act also bans selling what you grow and requires plants to start from seeds or seedlings that come from a legal source. Health Canada sets out the full rules on its Cannabis Act laws and regulations page.
Provinces cannot raise the limit above four, but they can lower it, add conditions or, as Quebec has done, ban home growing outright.
What are the home grow rules in each province and territory?
Every province and territory except Quebec allows four plants per household in 2026, but the conditions differ, especially for outdoor plants. The table below summarizes the main rules for adults growing for personal use.
| Province or territory | Legal age | Plants per household | Key conditions |
|---|---|---|---|
| British Columbia | 19 | 4 | Plants must not be visible from a public place; no growing in a home used as a daycare. |
| Alberta | 18 | 4 | Indoor or outdoor; secure plants from young people; leases and condo rules can ban growing. |
| Saskatchewan | 19 | 4 | Indoor or outdoor; landlords and condo boards can restrict it. |
| Manitoba | 19 | 4, indoors only | Allowed since 1 May 2025; must be grown indoors in a space people under 19 cannot reach; starting material from a licensed Manitoba store. |
| Ontario | 19 | 4 | Indoor or outdoor; legal seed or seedlings; municipal bylaws and lease terms apply. |
| Quebec | 21 | 0 | Home growing is prohibited; fines of $250 to $750 for a first offence. The Supreme Court of Canada upheld the ban in April 2023. |
| New Brunswick | 19 | 4 | Indoors in a separate locked space; outdoors behind a locked enclosure at least 1.52 m (5 ft) high; primary residence only. |
| Nova Scotia | 19 | 4 | The grow area must not be visible from a public space. |
| Prince Edward Island | 19 | 4 | Indoors out of reach of minors; outdoors out of public view in a locked enclosure at least 1.52 m high. |
| Newfoundland and Labrador | 19 | 4 | Four plants per household; local and lease restrictions apply. |
| Yukon, Northwest Territories, Nunavut | 19 | 4 | Allowed; community rules, leases and public housing policies may restrict it. |
Rules change, as Manitoba showed in 2025, so treat this table as a starting point and confirm on your provincial government site before you germinate.
What counts as a plant under the four-plant limit?
Any living cannabis plant counts, whatever its size or stage, so four seedlings in a tray use up your whole allowance. A plant stops counting once it is harvested; buds that are drying or curing are treated as cannabis you possess, not as plants.
- Seeds do not count as plants until they sprout. Federal possession rules treat one seed as equal to one gram of dried cannabis, and the public possession limit is 30 grams, so carrying more than 30 seeds in public can put you over.
- Clones and cuttings count as soon as they are rooted and growing. Taking cuttings from a mother plant only works if the total stays at four.
- Mother plants count. Keeping a mother in veg year round leaves you three spots for flowering plants.
- Germination timing matters. If you germinate six seeds to be safe, cull the weakest two as soon as you can tell them apart.

Can you grow cannabis outdoors in Canada?
Yes, you can grow outdoors everywhere that allows home growing except Manitoba, which requires plants to stay indoors. Outdoor growers in the other provinces still need to follow visibility and security rules, which are strictest in British Columbia, New Brunswick, Nova Scotia and Prince Edward Island.
In practice, outdoor plants should sit behind a solid fence or hedge, out of view of the street and of neighbouring windows where possible. Late September smell is the other practical issue; strong strains can be noticed from the next yard. Timing also matters, because most of Canada has a short season; our guide on when to plant cannabis outdoors in Canada gives plant-out dates by region.
Renters and condo owners
A landlord or condo board can ban growing in a lease or bylaw even where the province allows it. Read your lease before you start, since a breach can be grounds for eviction in several provinces.
Can you grow more than four plants in Canada?
Only people registered with Health Canada to produce cannabis for medical purposes, or someone designated to grow for them, can legally grow more than four plants. The number they may grow comes from a federal formula based on the daily amount authorized by a health care practitioner, and the registration certificate states it.
For everyone else, four is the ceiling, and it is enforced. Growing more is an offence under the Cannabis Act, and provinces such as Quebec add their own fines on top of federal rules.
How do you get the most out of four plants?
With only four plants allowed, the way to grow more is to make each plant count: choose feminized seeds, give each plant a bigger container and train it to fill its space. A well grown indoor photoperiod plant can produce 100 to 200 g dried, and an outdoor plant in a good Canadian summer can give 400 g or more.
- Grow feminized seeds. Regular seeds produce about half males, and a male still counts as one of your four until you remove it.
- Veg longer instead of planting more. An extra two weeks of vegetative growth indoors adds more yield than an extra seedling you are not allowed to keep.
- Train the canopy. Topping and low stress training spread each plant into many even tops, so one plant fills more of the tent.
- Use bigger pots. Twenty to fifty litre containers outdoors and 15 to 25 litres indoors let roots support larger plants.
- Stagger your harvests. Because harvested plants stop counting, you can start a new seed as soon as one plant comes down, which keeps a small grow productive all year.

Quick checklist before you plant
- Confirm your province allows home growing and note its age limit.
- Check your lease, condo bylaws and municipal rules.
- Count every living plant, including seedlings, clones and mothers.
- Keep outdoor plants out of public view and locked where your province requires it.
- Never sell what you grow at home.
Strains that make four plants count
- Big Bud: a heavy-yielding indica bred for weight, so fewer plants still fill a jar.
- White Widow: a forgiving, frost-heavy classic that rewards training in a small tent.
Frequently asked questions
How many weed plants can you grow in Ontario?
You can grow up to four cannabis plants per household in Ontario if you are 19 or older. Plants can be indoors or outdoors, must start from legal seeds or seedlings, and remain subject to municipal bylaws, lease terms and condo rules, which can restrict or ban home growing.
How many weed plants can you grow in Nova Scotia?
Nova Scotia allows up to four cannabis plants per household for adults 19 and older. The province follows the federal limit and adds one main condition: the growing area must not be visible from a public space, so outdoor plants need screening from the street.
Is the four-plant limit per person or per household?
The limit is four plants per household, not per person. It does not matter how many adults live in the home; the total number of living plants at the residence cannot exceed four. A person also cannot grow four plants at each of two homes.
Can you grow cannabis at home in Quebec?
No. Quebec prohibits growing cannabis at home for personal use, with fines of $250 to $750 for a first offence. The Supreme Court of Canada ruled in April 2023 that the provincial ban is constitutional, so it remains in force in 2026.
Do seedlings count toward the four-plant limit in Canada?
Yes. Every living cannabis plant counts, including seedlings, rooted clones and mother plants. Seeds that have not sprouted do not count as plants, although they count toward possession limits, with one seed treated as one gram of dried cannabis.
Every seed we sell is already in Canada: it ships from Vancouver in plain packaging and arrives in 3 to 7 business days, with an 80% germination guarantee behind it. When four plants are all you get, start with our feminized seeds.
