How to store cannabis safely at home

Last checked: September 30, 2026

With cannabis in your home, where you keep it matters as much as what you bought. Edible products in particular can pass for ordinary food, and packaging only helps if it's closed and put away. This guide sets out a simple storage routine for adults 19+, based on guidance from the Government of Ontario and Health Canada, along with what to do if something goes wrong.

The three-rule routine

Rule 1: lock it up

Ontario's Ministry of Health puts it simply: keep all cannabis products locked up, where neither children nor pets can reach them. That covers flower, pre-rolls, vapes, oils and edibles alike. Health Canada suggests a secure cupboard fitted with a strong childproof lock or latch, and says a lockbox or safe is worth considering.

A lockbox also solves a practical problem: it keeps everything in one place, so nothing ends up on a counter or in a coat pocket.

Rule 2: keep the original package

According to Health Canada, legal edible products come in plain, child-resistant packaging, and it advises keeping legal cannabis products in their original packaging to keep them more secure. The original label also records what the product is and how much THC it holds, so there's no guessing later.

A child-resistant package only works when it's properly closed. Reseal it every time.

Rule 3: keep edibles away from food

Ontario notes that edible cannabis products can look the same as other foods, such as brownies. Health Canada adds three habits:

store edible cannabis separately from regular food and drinks
label homemade edibles clearly, so no one mistakes them for regular food
never leave cannabis unattended anywhere a child could get to it

If you make edibles at home, Ontario is clear that they're for personal use, and you can't sell them or share them with anyone under 19.

Why "look-alike" edibles are a separate worry

Legal edibles in Ontario are capped at 10 mg of THC per package, and Health Canada says legal edibles must be in plain, child-resistant packaging. Health Canada warns that illegal edibles are different. They often don't come in child-resistant packaging, and they can have flashy packaging, sometimes mimicking brand-name candies and snacks. A product like that looks like a treat to anyone who doesn't read the fine print. The safest approach is to buy only legal products and to treat every edible, whatever it looks like, under all three rules above.

Room-by-room check

Take five minutes and walk through your home with this list:

Kitchen: Are any edibles sitting near regular snacks or drinks? Move them into your locked storage.
Bedroom and nightstand: Is anything in an open drawer? Lock it away.
Living room: Check coffee tables and couch cushions after guests leave.
Bags and coats: Handbags, backpacks and jacket pockets are easy for others to reach. Empty them into storage when you get home.
Car: Ontario's transport rule bars cannabis that's open and out of its package, or loose where someone in the vehicle could grab it. Bring it inside when you park at home, rather than leaving it in the glovebox.
Balcony, garage or shed: The same lock-it-up rule applies here too.

Visitors and shared homes

Storage habits get tested when other people are around. A few practical points:

If guests bring cannabis, ask them to keep it in a closed bag that's out of reach, or offer your lockbox.
If you live with roommates, agree on where cannabis is kept. Shared fridges and cupboards aren't the place.
Grandparents, sitters and anyone else caring for children in your home should know where cannabis is stored and that it stays locked.

If someone swallows cannabis by accident

Keep these numbers somewhere easy to find, such as on the inside of a cupboard door:

Poison centre: Health Canada directs people to call 1-844-POISON-X (1-800-463-5060 in Quebec) if you think a child has consumed cannabis. If the person loses consciousness or has trouble breathing, call 9-1-1.
Emergency: Ontario's guidance says that if someone is in immediate danger, call 911 or go to your nearest hospital or emergency department.

Quick answers

Is a regular kitchen cupboard good enough?

Only if it locks. Ontario's guidance says "locked up," and out of reach alone doesn't meet that.

Can I move edibles into a nicer container?

It's better not to. The original package is child-resistant and carries the label information.

Do pets need the same precautions?

Yes. Ontario's storage guidance names children and pets together.
