Under federal law, a legal recreational edible in Canada must not contain more than 10 mg of total THC per immediate container, a rule set out in the Cannabis Regulations. Provinces can add their own rules on top of that federal baseline. If you see an edible marketed with very high milligram amounts of THC, well beyond the legal cap, you’re not looking at a legal recreational product, but rather at an extract, a topical, or something sold outside the regulated market.
TL;DR:
- Edibles containing more than 10 mg of THC per container are illegal and likely represent extracts or products sold outside licensed markets.
- The federal cap refers to total THC in the sealed container, not per individual unit, so multiple small units can be legal if their combined THC stays within 10 mg.
- Labels must specify total THC per container, per discrete unit, and include official stamps and warnings to verify product legality and compliance.
- Provincial rules can restrict flavors, purchase limits, and retail formats, but the federal 10 mg limit remains the same across Canada.
- Starting with 2.5 mg THC and waiting at least two hours before considering second doses minimizes overconsumption risks due to delayed edible effects.

What the 10 mg cap actually means for your package
The rule sounds simple, but the wording trips people up: the limit is per immediate container, not per product. Your immediate container is whatever seals the product directly, the bag, box, or wrapper that touches the edible itself. A package can hold several individually sealed pieces, called discrete units, as long as the total THC across all of them stays at or under 10 mg.
Say a chocolate bar comes in four squares. Each square might carry 2.5 mg THC, adding up to 10 mg for the whole bar, and that’s legal. Two gummies at 5 mg each in one package also works. What doesn’t work is a single gummy claiming 10 mg with a second one tucked into the same wrapper: that pushes the container over the line. Health Canada’s composition requirements guidance is clear that when a package holds multiple units, those units have to be equal in potency, and the producer has to keep the combined total under the cap even accounting for normal manufacturing variability.
Here’s where it gets more technical: the cap counts total THC, not just the THC listed on a lab test before packaging. Raw cannabis and some edible ingredients contain THCA, an acidic precursor that converts to active THC when heated or, over time, through storage. Because that conversion can happen after a product leaves the lab, Health Canada’s rules require producers to calculate total THC as though full conversion has already occurred. That’s why you’ll often see “Total THC” as its own labelled figure rather than just “THC”, and it’s also why a product that tested slightly under 10 mg raw might still fail compliance once THCA conversion is factored in.
This distinction explains a lot of consumer confusion. A cannabis extract, like a concentrated oil or capsule, can legally contain up to 1,000 mg of THC per immediate container under a separate set of rules. Topicals fall under similar higher allowances. None of that applies to edible cannabis. If a gummy, chocolate, or beverage claims 100 mg, 500 mg, or 1,000 mg of THC, it is not a legal recreational edible sold through a licensed Canadian retailer, full stop. It’s either misbranded, sold illegally, or being confused with an extract product that isn’t meant to be eaten the way a chocolate bar is.
Understanding this distinction matters before you shop anywhere, in person or online. A retailer that clearly separates “Total THC per immediate container” from “Total THC per unit” on its listings is showing you it understands the rule, and that’s a decent proxy for whether the rest of its compliance is in order.
How to read a Canadian edible label before you buy
Every legal edible sold in Canada carries a specific set of label elements required under the packaging and labelling guide. Knowing what to look for takes the guesswork out of shopping, whether you’re standing in a retail store or scrolling an online menu.
- Total THC per immediate container: the figure that must sit at or under 10 mg, listed in milligrams.
- Total THC per discrete unit: shown when a package contains multiple pieces, so you know how much is in each piece you eat.
- Excise stamp: a small stamp confirming the product came from a federally licensed producer and had excise duty paid on it.
- Standardized cannabis THC symbol: the universal red stop-sign style icon that flags any product containing THC.
- Bilingual health warning: a rotating warning message printed in both English and French, as required for all cannabis products sold in Canada.
- Child-resistant packaging: packaging that meets specific mechanical standards to make it harder for kids to open.
- Nutrition facts table: required on edibles the same way it’s required on regular food products, listing calories, sugars, and other standard values.
Each item does real work. The excise stamp alone tells you the product moved through the legal supply chain rather than an unregulated one. The standardized symbol is your fastest visual cue: no symbol, no legal THC content, at least in theory. Child-resistant packaging matters just as much for households with kids or pets as it does for regulators.
Watch for red flags too. A missing excise stamp is the clearest sign something’s off. Packaging that leans into cartoon branding, bright colours aimed at kids, or names that mimic popular candy and snack brands violates the intent of the regulations even if it slips through somewhere. Any unlabelled or vague THC claim, especially one that sounds too high for a legal edible, is a signal to walk away. If you want a deeper walkthrough of what’s printed where and why, Montrose Cannabis has a full breakdown of Canadian cannabis labels worth bookmarking before your next order.
Provincial rules layered on top of the federal cap
The federal 10 mg limit is the floor everywhere in Canada, but provinces run their own retail systems and can add extra restrictions on how those products get sold, possessed, or displayed.
- Québec takes the strictest approach among provinces, banning edibles that resemble candy, dessert, or other food likely to appeal to youth, and applying its own portioning rules on top of the federal cap.
- Possession limits for adults, generally tied to the equivalent of 30 grams of dried cannabis, apply federally, but how retailers structure purchase limits per transaction can differ by province.
- Retail structure varies too: some provinces run government-operated stores exclusively, others license private retailers, and each sets its own rules for how edibles are displayed and sold.
None of this changes the 10 mg per container ceiling itself, that’s federal and applies everywhere. What changes is execution: which flavours or formats are allowed on shelves, how much you can buy in one visit, and how retailers are permitted to market these products. If you’re ordering from outside Ontario or travelling within Canada, it’s worth checking your home province’s cannabis retail or public health page before assuming a product available in one region is sold the same way everywhere. The platform serves Ontario customers directly with one-hour delivery in certain regions, so Ontario’s retail rules govern orders placed through it.
Start low, go slow: a practical dosing plan
Knowing the legal limit doesn’t tell you what dose is right for you, and that’s where Health Canada’s harm-reduction guidance fills the gap. The official dosing recommendations suggest new or occasional consumers start at 2.5 mg THC or less. Doses between 2.5 and 10 mg call for caution, and 10 mg or more, even though it’s within the legal cap, carries the highest caution of all for anyone without a strong tolerance built up over time.
Timing catches a lot of people off guard. Effects from an edible typically begin 30 minutes to 2 hours after eating, and can take up to 4 hours to fully develop. For some people, the total experience runs 6 to 12 hours. That slow, unpredictable onset is the single biggest reason people accidentally overconsume: they don’t feel anything after 45 minutes, assume the dose was too low, and eat more before the first dose has even peaked.
A simple plan keeps you on the safe side of that curve:
- Pick a starting dose of 2.5 mg or less if you’re new or haven’t used cannabis in a while.
- Eat something beforehand since an empty stomach can change how quickly THC gets absorbed.
- Wait at least 2 full hours before considering any additional dose, since that’s roughly the window for full effects to show up.
- Track how you feel in a note on your phone, including the time you ate the edible and any effects as they build.
- Skip alcohol and other sedatives the same day, since combining depressants with THC increases the odds of an unpleasant or risky reaction.
Pro Tip: Set a timer for two hours the moment you eat an edible, and put any remaining units out of sight in a drawer or cupboard so they’re not staring back at you while you wait.
If you’re still working out what dose fits your tolerance, Montrose Cannabis has a dedicated guide on safe edible dosing that walks through the same start low, go slow principle in more detail, along with how to compare THC and CBD edibles if you’d rather ease in with a lower-THC or CBD-forward option.
What to do if someone overconsumes
Eating too much THC is unpleasant, sometimes frightening, but rarely dangerous on its own. Common symptoms include a racing heart, anxiety, nausea, dizziness, and in some cases vomiting or a sense of panic.
- Stay calm and keep the person seated or lying down in a quiet space away from noise and crowds.
- Offer water and reassurance, reminding them that the feeling will pass even though it’s intense.
- Call the Poison Control centre or 911 if symptoms are severe, if the person is a child, or if you’re unsure what or how much was consumed.
- Have the product label ready when you call, along with the amount eaten and the time it was ingested.
- Store all edibles in child-resistant packaging, out of reach and out of sight, especially in homes with kids or pets.

FAQ
Is it okay to eat 100 mg of edible?
A legal recreational edible sold in Canada cannot contain 100 mg of THC in one immediate container, since the federal cap is 10 mg total THC. A product claiming 100 mg is either an extract, mislabelled, or sold outside the legal market, and consuming that much THC at once carries a high risk of an unpleasant reaction for anyone without significant tolerance.
How long can a 1,000 mg edible last?
A 1,000 mg product isn’t a legal recreational edible in Canada, since edibles are capped at 10 mg total THC per container, though some extract products can legally reach that potency. For a legal edible dose, effects typically begin within 30 minutes to 2 hours, peak by around 4 hours, and can last 6 to 12 hours for some people.
What is the highest THC allowed in Canada?
For edible cannabis specifically, the highest legal amount is 10 mg total THC per immediate container, a limit set by the Cannabis Regulations. Other product classes, like extracts and topicals, have separate and higher limits under federal rules, but those figures never apply to edibles.
Is it safe to take 20 mg of edibles?
A dose above the highest caution threshold Health Canada flags at 10 mg or more isn’t recommended for new or occasional consumers. Anyone considering higher amounts should have an established tolerance, since delayed onset means the full effect may not be felt for hours after eating.
