Is a bigger e-liquid bottle cheaper per mL?
Among the stated bottle sizes with enough listings to compare, the median price per millilitre is $0.83 at 30 mL and $0.42 at 100 mL — 713 and 46 listings respectively, last checked October 15, 2026. Federal duty on its own falls from $0.26 per mL to $0.16 per mL across those same two sizes.
Price and duty by stated bottle size
The table below lists every stated E-Liquid bottle size with at least 25 qualifying listings, alongside the federal duty on a container of that size — see vape tax in Canada, explained for the full duty formula.
| Size | Listings | Median price | Median $/mL | Typical range ($/mL) | Duty / container | Duty / mL |
|---|---|---|---|---|---|---|
| 30 mL | 713 | $24.99 | $0.83 | $0.68–$0.97 | $7.84 | $0.26 |
| 60 mL | 330 | $26.49 | $0.44 | $0.34–$0.60 | $11.20 | $0.19 |
| 100 mL | 46 | $42.00 | $0.42 | $0.31–$0.52 | $15.68 | $0.16 |
Do British Columbia and Quebec limit how big a bottle can be?
Yes. British Columbia caps a refill container at 30 mL and a pod or cartridge at 2 mL; Quebec applies the identical 30 mL and 2 mL limits. No other province or territory has a publicly documented retail limit on bottle size, and there is no federal one — federal law fixes nicotine concentration and child-resistant packaging, not how large a container may be. The 20 mg/mL federal nicotine cap applies at every one of these sizes regardless; see nicotine strength: what mg/mL and percentages mean for how that figure works. The fuller set of rules that apply to an online sale — minimum age and which provinces charge extra vaping duty among them — is in what the law says about buying vapes online in Canada.
Salt and freebase listings, by bottle size
Within the same qualifying sizes, here is how many listings’ titles read as nicotine salt, freebase, or name neither term — a count, not a strength comparison. What the two terms mean, and the strengths each is actually listed at, is covered in nicotine salt and freebase e-liquid: what the labels mean.
| Size | Nicotine salt | Freebase | Unstated |
|---|---|---|---|
| 30 mL | 432 | 49 | 232 |
| 60 mL | 82 | 59 | 189 |
| 100 mL | 2 | 3 | 41 |
How these numbers were built
A listing counts as a stated bottle here only when it is filed under the E-Liquid category, its title states exactly one millilitre figure (a title stating two different figures, or a per-unit figure next to a multipack count such as “3 x 10 mL”, is left out rather than guessed at), and it is priced above zero. Titles that read like a pod, disposable or device — a stated puff count, the word “pod” or “cartridge”, or the names of a few pod and disposable product lines — are excluded even when filed under E-Liquid, since some big-format prefilled pods and disposables are mis-categorised that way in the source data. A size is only published in the table above once at least 25 listings state it, and nothing under 10 mL is treated as a bottle at all.
For the format comparison this data feeds into — disposables and pods against refillable bottles, on a cost-per-millilitre basis — see disposable and refillable vapes: the cost per millilitre, and for a pod or disposable’s own stated capacity, see how much e-liquid is in a pod or a disposable vape. Current bottle listings themselves are in the e-liquid catalogue, and every bottle ranked by what it costs per mL is on the cheapest e-liquid by price per mL.
