In Canada, the child-resistant requirement applies to the immediate container, the one that actually touches the product. The outermost box does not have to be child resistant at all. And the standard itself is a measured delay rather than a lock: a package passes if at least 85 percent of a test group of young children cannot open it, and at least 90 percent of adults can. That design is deliberate, and understanding it changes how you store cannabis at home.
What the regulations actually require
Section 108 of the Cannabis Regulations sets out the rules for containers. Among other things, the immediate container must be opaque or translucent, prevent contamination, keep the contents dry, and meet the requirements of a child-resistant package under subsections C.01.001(2) to (4) of the Food and Drug Regulations.
Health Canada's own packaging and labelling guide is explicit about the limit of that rule. Of the outermost container it states: "The outermost container does not need to: be child resistant."
Two further carve-outs are worth knowing. The child-resistant requirement does not apply to cannabis plants or cannabis plant seeds. And shipping containers, the outer wrappings and boxes used to transport product, fall outside the packaging rules entirely.
| Container | Must be child resistant? |
|---|---|
| Immediate container (the pouch, tin or blister holding the edible) | Yes |
| Outermost container (an outer carton or sleeve) | No |
| Shipping container (courier box, outer wrapping) | Outside the packaging rules |
| Cannabis plants and plant seeds | Exempt |
In practice, the part of the package you are most likely to discard is often not the part doing the safety work. If you open a carton and throw it away, the pouch inside is the child-resistant element. If you decant into a jar or a drawer, nothing is.
What the child-resistant test measures
The Food and Drug Regulations standard is unusually concrete, and it is worth reading closely because the numbers tell you what the packaging is for.
A package is tested on a group of at least 200 children between 42 and 51 months of age. It passes if it "cannot be opened by at least 85 per cent of those children prior to a demonstration" of how it opens, and by at least 80 percent after the demonstration. Separately, at least 90 percent of adults in an adult test group must be able to open it. A manufacturer may instead meet Canadian Standards Association Standard CAN/CSA-Z76.1-M90, Recloseable Child-Resistant Packages.
Read that again with the arithmetic in view. The standard tolerates up to 15 percent of tested children opening the package before anyone shows them how. It is engineered to buy an adult time, not to be impassable. The regulator's own term is "child resistant," and the word resistant is doing real work.
The age band is the other detail worth sitting with. Children aged 42 to 51 months are three and a half to just over four years old, and that is squarely the group most often involved in real cannabis poisonings.
What the Canadian data shows
Ontario has unusually detailed published figures on this.
A study by ICES and the Ottawa Hospital Research Institute, published in JAMA Network Open in January 2022, tracked 522 emergency department visits for cannabis poisoning in Ontario children under 10 between January 2016 and March 2021. The average age was three years, nine months. Monthly visits rose from 2.5 before legalization, to 7.8 after dried flower and oils became legal, to 22.6 per month after commercial edibles reached shelves in early 2020. Across the whole period, 171 visits (32.7 percent) led to hospital admission and 19 (3.6 percent) to intensive care.
A national study published in BMC Public Health in October 2023, covering children aged 0 to 11 from 2015 to 2021, found the rate of cannabis-related emergency department visits in Ontario rose from 0.3 per 100,000 in 2015 to 18.1 per 100,000 in 2021. Hospitalizations across Canada excluding Quebec rose from 0.5 to 6.4 per 100,000. Among edible-related events, the largest single product type was gummies at 48.8 percent, followed by candy at 12.6 percent, cookies at 10.9 percent and chocolate at 8.9 percent.
The most useful figure in that paper is the last one: 88 percent of cannabis edible-related events were attributed to inadvertent ingestion due to access to such products or a lack of safe storage practices. Access and storage, not packaging failure, are where almost all of these cases begin.
What a cannabis poisoning looks like
The Ontario Poison Centre lists the effects it sees in children who have unintentionally eaten cannabis: vomiting, agitation, confusion, slurred speech, unsteadiness on the feet, drowsiness or lethargy, muscle weakness, slowed breathing, coma, and seizures, which are rare. It notes that "symptoms can vary from none at all to a coma" and that "some children have required a breathing tube and have needed to be closely monitored in an intensive care setting."
Health Canada's guidance is consistent with this and adds that in rare cases these poisonings have been fatal.
Storing cannabis at home
The guidance from Health Canada and the Ontario Poison Centre converges on four points.
- Keep the product in its original child-resistant container. Health Canada's advisory states that cannabis "should always be kept in its original child-resistant packaging." Decanting into a jar, tin or bag removes the only engineered barrier in the chain.
- Lock it. The Ontario Poison Centre's advice is to "store all cannabis products in a locked box or container." A high shelf is not a lock. Its public campaign phrase is High and Locked.
- Keep it away from food. Store cannabis "separate from regular food and drinks." An edible in the kitchen cupboard or the fridge door is in the place a child has been taught to look for something to eat.
- Label anything you move. If a product has to leave its original packaging for any reason, make sure the new container is clearly labelled.
Two structural facts make the cupboard rule matter more than it sounds. Legal edible packages in Canada are capped at 10 mg of THC per package, which limits the size of a worst case. And legal packaging is plain and uniform by law, which is precisely why it does not look like something to eat. We cover this in why cannabis packages have a window now and what the 2026 edible rules changed.

If you think a child has taken cannabis
The Ontario Poison Centre is a free telephone toxicology service staffed 24 hours a day, every day of the year, for the public and for health-care professionals.
- Ontario Poison Centre: 1 800 268 9017
- If a child is unresponsive, having difficulty breathing or seizing, call 911.
Bring the package with you if you go to hospital. The label carries the THC content per unit and per package, the product class and the licence holder, and that information helps clinicians considerably.
The short version
Child-resistant packaging in Canada is a real, tested engineering standard applied to the immediate container, and it is not applied to the outer box. It is designed to slow a three- or four-year-old down, and by its own published tolerances it will not stop every one of them. The Canadian data is clear that the decisive variable is not the package. It is whether the product was locked away and kept apart from food.
Our staff can walk you through what is printed on any package we carry, including THC per unit and per package. We cannot give medical advice. If you want to look at how a particular product is packaged before you buy, come by the shop at 811 Dundas St W, or see what is currently on our shelves.
