Health Canada's 10 mg rule, and what it means for homemade edibles
Every legal edible sold in Canada carries the same ceiling: 10 milligrams of THC per package, whether that package is one chocolate or a bag of ten gummies. Homemade edibles have no such cap, which is exactly why the number is worth understanding. It is the regulator's best guess at a package an adult can eat in one sitting without a bad night, and it makes a very good rule of thumb in your own kitchen.
What does the 10 mg rule actually say?
Under the federal Cannabis Regulations, edible cannabis sold by licensed retailers may contain no more than 10 mg of THC per package. A package can hold several pieces, but the pieces together cannot exceed 10 mg. Beverages follow the same package limit. The rule is about the container, not the serving, which is why a legal chocolate bar is often scored into 2 mg or 2.5 mg squares.
The limit exists because edibles are slow and easy to overdo: the delay between eating and feeling anything tempts people to take more, and a package cap stops one impulsive evening from becoming a very long one.
Does the 10 mg limit apply to edibles I make at home?
No. Adults in Canada may make cannabis edibles at home for personal use from legally purchased cannabis, and there is no milligram cap on a homemade batch. The one federal restriction on home preparation is that you may not use organic solvents such as butane to make concentrates. Butter, oil, and a stovetop are fine.
That freedom is the whole point of cooking your own: you choose the strength. It is also the risk. A tray of brownies made from seven grams of flower can hold several hundred milligrams, and without a label the only thing telling a guest how much is in a square is you.
How do I use the rule in my own kitchen?
Treat 10 mg as the most a single serving of anything you make should carry, and 2.5 mg as the starting point for anyone new. Work out the total milligrams in the batch with the dosage calculator, divide by servings, and if a serving lands above 10 mg, cut smaller pieces or dilute the infusion with plain butter or oil.
Then label like a licensed producer would: what it is, the date, and the milligrams per piece. A homemade edible that looks like a store-bought one deserves the same clarity, especially in a house with other adults, kids, or pets.
Frequently asked questions
Can I buy edibles stronger than 10 mg in Canada?
Not legally. Every edible or beverage sold through a licensed retailer is capped at 10 mg of THC per package. Products advertised above that are outside the legal market and have no tested dose.
Is it legal to make edibles at home in Canada?
Yes, for adults of legal age in their province, using legally purchased cannabis, as long as no organic solvents are used. You may not sell them.
Why are legal edibles so weak?
They are not weak so much as capped. Ten milligrams is a meaningful dose for many people, and the cap is designed around new and occasional users. Regular users often find it low, which is one reason home cooking is popular.
Educational content for adults of legal age, not medical advice. Cannabis affects everyone differently — start low, go slow.
