Are vape puff counts accurate?
No. A puff count printed on a disposable or pod’s packaging is not measured against any method that Canadian federal or provincial rules define or check, so a number on one product cannot be compared with a number on another. It is an estimate the manufacturer works out privately, from assumptions about puff size and length that are never printed alongside it.
None of the primary sources this cluster relies on — the Excise Act, 2001, the Canada Revenue Agency’s vaping duty notices, or any provincial vaping tax or product rule tracked here — set out a required test, a fixed puff duration, or a mandatory way to report a puff count. What Canadian law does fix, in millilitres, is how much e-liquid a container holds and, in a couple of provinces, how large that container is allowed to be. That is the figure this page works from, and the sections below show why it holds up where a puff count does not.
How is a puff count actually calculated?
A puff count is arithmetic, not a measurement of the finished product. A manufacturer decides how much e-liquid it assumes is drawn into a single puff and how long it assumes that puff lasts, then divides the container’s total millilitres by that assumed volume per puff. Neither assumption is printed on the packaging, and neither is fixed by any regulation this cluster has a primary source for. Two disposables holding the exact same millilitres of e-liquid can carry different puff-count claims without either manufacturer being wrong, because they simply started from different draw and duration assumptions. It works in reverse too: two products advertising the same puff count are not guaranteed to hold the same amount of e-liquid.
What does Canadian law actually regulate?
Two figures at the container level are fixed rather than chosen by a manufacturer’s marketing department. One is how concentrated the nicotine in the e-liquid is allowed to be, which is set federally — Nicotine strength: what mg/mL and percentages mean covers that cap on its own. The other is the millilitres of e-liquid the container holds: a physical quantity that is printed on the label, can be checked against the liquid itself, and is also the exact figure the federal government uses to calculate vaping duty. The next two sections work through that duty and a provincial container limit in turn.
Why federal vaping duty is calculated in millilitres, not puffs
Federal vaping duty is charged per immediate container — one disposable, one pod, one bottle — under Schedule 8 of the Excise Act, 2001: $1.12 CAD per 2 mL or part of a 2 mL, for the first 10 mL a container holds, then the same $1.12 per additional 10 mL or part of a 10 mL after that. The table below applies that formula to a run of container sizes, computed the same way the duty itself is.
| Container size | Federal duty (CAD) |
|---|---|
| 2 mL | $1.12 |
| 5 mL | $3.36 |
| 10 mL | $5.60 |
| 20 mL | $6.72 |
| 30 mL | $7.84 |
Duty rises with millilitres in a fixed, checkable way, and has no term in it for a puff-count claim at all. Two disposables with very different advertised puff counts but the same millilitres of e-liquid are charged exactly the same federal duty; two disposables with the same advertised puff count but different millilitres are not. In a specified vaping province the amount in this table is charged a second time on top of itself — Vape tax in Canada, explained works through that doubling and what it does to a multi-pack compared with a single bottle.
Do any provinces cap the size of the container itself?
Two do: British Columbia and Quebec. British Columbia caps a device’s tank or pod at 2 mL and a refill bottle at 30 mL; Quebec applies the identical 2 mL tank and 30 mL bottle limit. Both limits sit on the container itself, not on any puff estimate — see British Columbia’s tax and product rules and Quebec’s tax and product rules for the rest of what applies in each. Every other province and territory this site tracks sets no equivalent container-size limit, and none of them, British Columbia and Quebec included, places any limit on a puff-count number itself.
What should you compare instead of the puff count?
Two figures hold up across products because both are physical measurements rather than manufacturer arithmetic: the millilitres of e-liquid in the container, and the price paid per millilitre once duty, sales tax and any provincial vape-specific tax are included. Disposable and refillable vapes: the cost per millilitre works that arithmetic through for both formats side by side, and How much does a vape cost in Canada? builds the full delivered price from shelf price to shipping. The stated millilitre figures themselves, by disposable and pod-system capacity, are in how much e-liquid is in a pod or a disposable vape.
The catalogue lists millilitres for every tracked disposable, e-liquid and pod system, alongside the hardware that refills them, priced across the stores and brands in the directory. The price index turns that millilitre figure into cost per millilitre, and the price catalogue shows what each tracked listing currently costs. Provincial duty and sales tax on top of that figure are set out per province at the provincial tax pages. For shoppers who compare by the advertised figure anyway, disposables ranked by price per 1,000 rated puffssets each device’s median price against its rating, with the same caveat stated on the page.
