In Canada a gram of flower runs roughly $4–6, an ounce $119–130, a quarter pound $238–450 and a pound $900–1,500, with price per gram falling by more than half as you move up the ladder. Below are current listed prices at every weight, the per-gram arithmetic worked out, and the thing almost nobody mentions: the industry weight ladder is about 1.2% lighter than the imperial weights it borrows its names from.
Key Takeaways
- Price per gram falls steeply with weight. The same grade runs about $4.29/g by the ounce and $3.35/g by the pound.
- Grade moves price as much as weight does. A AAA quarter pound and a AAAA quarter pound differ by $150 for identical mass.
- The retail ladder is short. 28 g, 112 g and 448 g are each about 1.23% lighter than the true ounce, quarter pound and pound.
- Popcorn is the cheapest real flower, about $2.01/g at the pound tier against $3.35/g for full-size AAAA.
- Free shipping thresholds are part of the price. Most Canadian dispensaries ship free over $150.
- Canada's public possession limit is 30 g dried. Bulk buying is for storage at home, not for carrying.
Weights, Gram to Pound
Cannabis is sold in imperial fractions and weighed in metric. The retail figures are rounded conventions, not conversions:
| Name | Retail grams | True grams |
|---|---|---|
| Gram | 1 g | 1 g |
| Eighth | 3.5 g | 3.54 g |
| Quarter | 7 g | 7.09 g |
| Half ounce | 14 g | 14.17 g |
| Ounce | 28 g | 28.35 g |
| Quarter pound | 112 g | 113.40 g |
| Half pound | 224 g | 226.80 g |
| Pound | 448 g | 453.59 g |
Our guide to weed measurements covers the conversions, joints per ounce and how to weigh accurately.
The Weights Are Short, By How Much
Every tier on the retail ladder is about 1.23% lighter than the imperial weight it is named after, and the shortfall is identical all the way up because the whole ladder is built from a 28 g "ounce" rather than a 28.3495 g one.
Why it matters: when you divide a pound price by 448 instead of 453.59, your per-gram figure comes out 1.23% lower than reality. Everyone quotes the retail convention, so comparisons stay fair. Just do not expect 453 g on the scale.
Prices at Every Weight
These are current listed prices from Canadian dispensaries, with the division shown. Full-size AAAA flower first:
| Weight | Grams | Price | Per gram | Store |
|---|---|---|---|---|
| Quarter | 7 g | $40 | $5.71 | MMJ Express |
| Half ounce | 14 g | $64 | $4.57 | Bulkweedinbox |
| Ounce | 28 g | $119 | $4.25 | Bulkweedinbox |
| Ounce | 28 g | $120 | $4.29 | MMJ Express |
| Quarter pound | 112 g | $450 | $4.02 | MMJ Express |
| Half pound | 224 g | $800 | $3.57 | MMJ Express |
| Pound | 448 g | $1,500 | $3.35 | MMJ Express |
Drop a grade or take popcorn and the ladder shifts down sharply:
| Product | Grams | Price | Per gram | Store |
|---|---|---|---|---|
| AAA quarter pound | 112 g | $300 | $2.68 | MMJ Express |
| AAAA popcorn quarter pound | 112 g | $300 | $2.68 | MMJ Express |
| Mixed flower, 4 oz | 112 g | $238 | $2.13 | Bulkweedinbox |
| AAAA popcorn half pound | 224 g | $500 | $2.23 | MMJ Express |
| Mixed flower, 8 oz | 224 g | $420 | $1.88 | Bulkweedinbox |
| AAAA popcorn pound | 448 g | $900 | $2.01 | MMJ Express |

Shopping for an ounce? We compared every ounce eight online dispensaries listed, per gram and grade by grade: how much an ounce of weed costs in Canada.
The Per-Gram Arithmetic
Two levers move your per-gram cost, and they are roughly equal in size.
| Lever | From | To | Saving |
|---|---|---|---|
| Weight: quarter to pound, same grade | $5.71/g | $3.35/g | 41% less |
| Grade: AAAA to AAA at the same quarter pound | $4.02/g | $2.68/g | 33% less |
| Both: quarter of AAAA to a pound of popcorn | $5.71/g | $2.01/g | 65% less |
Which lever to pull depends on what you are optimising. If appearance matters, move up the weight ladder and keep the grade. If cost is the only thing that matters, popcorn at the pound tier is the cheapest real flower on the market.
Is $120 for a Quarter Pound Good?
It would be exceptionally cheap: cheap enough to check carefully. At $120 for 112 g you are paying $1.07 per gram. Nothing in the current Canadian listings above comes close: the cheapest quarter pound here is $238 (about $2.13/g) for mixed flower, and AAAA at that weight runs $450.
That does not make $1.07/g impossible: clearance, a mislabelled tier or genuinely low-grade material can all land there. It does mean the offer deserves the checks in the price-check section below before you commit, particularly on grade, actual weight and how recently it was packaged.
Why Price Per Gram Drops With Quantity
The per-gram discount at volume is not generosity. It reflects real cost structure:
- Packaging and labour cost roughly the same per unit whether the unit is an eighth or a pound.
- Shipping is close to flat per parcel, so it spreads thinner across more grams. Most Canadian dispensaries ship free above $150, which effectively removes it entirely at the bulk tiers.
- Payment and handling fees are largely fixed per order.
- Inventory risk shifts to you: the store converts stock to cash immediately instead of holding flower that degrades.
That last point is the one buyers underestimate. A bulk discount transfers the storage problem along with the flower, and badly stored flower loses value. See how long weed lasts and how to store it.
What Actually Drives the Price
| Factor | Effect on price |
|---|---|
| Quantity | Largest single lever: up to about 41% per gram across the ladder |
| Quality grade | Comparable in size, roughly a third between AAA and AAAA |
| Bud size (popcorn vs full-size) | Substantial, and independent of grade |
| Legal vs illegal channel | Measurable difference in reported prices between the two[1] |
| Province | Varies: legal retail pricing differs by jurisdiction[2] |
| Strain or cultivar | Smaller than most buyers assume at the same grade and weight |
Note the last row. Within the same grade and weight tier, which strain you pick moves the price far less than any of the rows above it. Grade and quantity do the heavy lifting.
The 30 g Possession Limit
Canada's public possession limit is 30 grams of dried cannabis or equivalent, roughly one ounce.[4] Buying a pound is legal; carrying it around in public is not.
The limit applies to public possession, not to what you may keep at home, and provinces can add their own rules on top. If you buy at the bulk tiers, the practical consequence is that the flower stays stored and you carry out what you need.
How to Price-Check a Bulk Offer
- Divide by grams, always. Headline prices across different weights are not comparable; per-gram figures are.
- Confirm which weight convention is being used: 448 g or 453.59 g changes the per-gram figure by 1.23%.
- Check the grade and whether it is popcorn. A cheap quarter pound is usually cheap for a stated reason.
- Add shipping unless the order clears the free threshold, then recalculate per gram.
- Apply any coupon before comparing, not after.
- Ask when it was packaged. Price per gram means nothing if a third of it degrades before you use it.
