How to read a cannabis label in Canada
THC and CBD numbers, the standardized cannabis symbol, equivalency, and what every part of the package means.
Legal cannabis packaging in Canada is tightly regulated, which is good news, because once you know what to look for, the label tells you everything you need.
The standardized cannabis symbol
Every product containing THC carries the red standardized cannabis symbol, a stylized cannabis leaf in an octagon. If it’s not there, the product isn’t legal.
THC and CBD content
The two numbers that matter most:
- Total THC: the potency that drives intoxication. Shown as a percentage (flower) or milligrams (edibles, oils).
- Total CBD: the non-intoxicating compound.
“Total” matters: it accounts for the THC that becomes active once heated, so it’s the real-world number.
Other label elements
- Equivalency: how the product counts toward your 30 g public possession limit.
- Packaging and lot number: for traceability and recalls.
- Health warning: a rotating set of required messages.
- Packaged-on date: useful for judging freshness (especially flower).
The plain-packaging rule
Canadian cannabis packaging is deliberately plain, no bright branding, no lifestyle imagery, child-resistant. That’s by design, to reduce appeal to youth. A flashy package is a red flag for an illegal product.

Frequently asked questions
What does the THC number on a label mean?
It's the potency, by percentage for flower, or in milligrams for edibles and oils. Higher means stronger, not necessarily better.
What is the standardized cannabis symbol?
The red 'THC' stop-sign symbol that must appear on every legal Canadian product containing THC. No symbol is a red flag.
What does 'equivalency' mean on cannabis packaging?
It's how a product counts toward the 30 g public possession limit. Our possession calculator does the math.
How can I tell a product is legal from the label?
Legal packaging carries an excise stamp, the standardized THC symbol, lab-tested potency, and plain regulated labelling.
