Cannabis Edibles in Ontario: The 10 mg Rule and Start-Low Basics

Edibles in Ontario are capped at 10 mg of THC per package. Here is what the rule means, how to read the label, and Health Canada's start-low numbers.

In Ontario, every package of cannabis edibles is capped at 10 mg of THC, under section 102.7 of the federal Cannabis Regulations. Health Canada suggests first-time buyers look for edibles with 2.5 mg of THC or less, and notes that effects are felt within 30 minutes to 2 hours and can take up to 4 hours to peak.

That is the short version. Below is what the 10 mg rule actually says, how to read an edible label, and the start-low basics that matter most with this format.

The 10 mg rule, explained

The regulation says edible cannabis must not contain more than 10 mg of THC per immediate container, taking into account the potential to convert THCA into THC. Health Canada's classification guidance calls this a precautionary limit.

Three things people often miss:

• It is per package, not per piece. A package can be split into several pieces. Four pieces of 2.5 mg each, or two pieces of 5 mg each, both add up to 10 mg.
• It applies to all edible cannabis, including foods and drinks. Cannabis beverages follow the same cap; see our cannabis beverages guide.
• Extracts follow different rules. Cannabis extracts can contain up to 1,000 mg of THC per immediate container, and ingestible extracts in discrete units, such as capsules, are capped at 10 mg per unit, according to Health Canada's composition requirements.

Edibles vs oils and capsules

Because the limits differ so much, the product class matters. Health Canada classifies a product as edible cannabis when it is represented as food or to be mixed with food, including drinks. An oil in a bottle that is measured with a syringe was generally not consumed for a food purpose and can be classified as an extract.

On our menu, foods sit under edibles, ready-to-drink products under beverages, and measured oils under oils and drops. The product class is always printed on the label, so you can check it for yourself.

What can go into an edible

The composition rules are stricter than many people expect. According to Health Canada's composition guide:

• Edible cannabis may contain only food and food additives, alongside the cannabis.
• Purified caffeine is prohibited. Caffeine is allowed only from naturally caffeinated ingredients, and the total in each package cannot exceed 30 mg.
• Alcohol cannot exceed 0.5% weight-by-weight of the product.

The regulations also prohibit selling edible cannabis whose unopened package has to be stored at or below 4°C to prevent contamination, so legal edibles are shelf-stable products.

How to read an edible label

Edibles carry more label information than most cannabis products:

• Total THC per unit and Total THC for the whole package, both in milligrams.
• Total CBD per unit and Total CBD.
• Number of units and the net weight (or net volume for liquids).
• A full ingredients list, in descending order of weight.
• Food allergens, gluten and added sulphites.
• A nutrition facts table.
• The standardized cannabis symbol, a health warning, the excise stamp, the lot number and the packaging date.

Start low, go slow: the timing matters

The biggest difference between edibles and inhaled products is timing. Health Canada's figures:

Health Canada's consumer information adds that effects from ingesting cannabis typically last 4 to 8 hours, that some lingering effects can last 12 to 24 hours, and that the delayed effects may lead to overconsumption.

The practical guidance from Health Canada's lower your risks page:

1. Look for products with 2.5 mg of THC or less.
2. Wait to feel the effects before taking more.
3. Avoid combining cannabis with alcohol or other intoxicating substances.

Edibles and the possession limit

Ontario's public possession limit is 30 grams of dried cannabis or the equivalent. Under Schedule 3 of the Cannabis Act, 15 g of solids containing cannabis counts as 1 g of dried cannabis, which means the limit equals 450 g of solid edibles. The equivalent is based on product weight, not on THC content. Our possession limits guide covers every format.

The AGCO applies the same idea to purchases: customers cannot buy more than 30 grams of dried cannabis, or the equivalent, at one time.

Storage: the most important rule

Edibles look like ordinary food. Health Canada says to keep all cannabis out of sight and reach of children and pets and to store it in its original child-resistant packaging, and warns that edibles can be dangerous to young children. A locked box or cabinet is the simplest way to follow that advice at home, especially in a shared condo or apartment.

Where you can eat them

Eating cannabis counts as consuming it. Ontario says you cannot consume cannabis, including eating it, in a vehicle or boat that is being driven or will be driven, and the province restricts consumption in places such as enclosed public spaces, workplaces and school grounds.
