What your cannabis store actually paid: the OCS math, step by step
The one-line formula that reveals what every Ontario cannabis store paid for its stock — plus the real receipts and where your money actually goes.
Some legal cannabis in Ontario is selling for less than the store paid the government for it — and the math to prove it is public. Here is the whole trick, written down so you can use it at the counter.
The one-line formula
OCS price ÷ 1.57 = what your store paid.
Why it works: OCS.ca lists every product tax-in. The OCS's own pricing guide says it verbatim — the retail price on OCS.ca is the wholesale price (the price your local store pays), plus a fixed 39% e-commerce markup, plus HST. Run it backwards: divide the OCS.ca price by 1.13 for the tax, then by 1.39 for their markup. That's the floor — the number every licensed store in Ontario paid for that product.
A real example
Back Forty's Backpackers Liquid Imagination, ten 0.75g pre-rolls. OCS.ca: $41.65, taxes included. Divide by 1.57 and the wholesale floor is $26.52. On price-comparison site hibuddy.ca (Sep 18, 2026), roughly 200 Ontario stores carried that tin — the cheapest at $26.25 (27 cents under the floor) and the most expensive at $42.99. Same tin. A 64% spread, decided by nothing but which door you walk through.
Where the money goes
Build the price from the farm up (estimates from published formulas): the federal government takes excise before the tin ships — the greater of $1.00/gram or 10% of price, so about $7.50 on 7.5 grams. Producer price plus excise plus freight is the "landed cost" (call it ~$21 here); the OCS adds its wholesale markup to reach $26.52; the store adds whatever the price war allows; the till adds 13% HST. On a $33.64 all-in purchase, the people who grew and rolled the product kept roughly $13. Government — excise, OCS margin, sales tax — took roughly $17. That's not a scandal; it's the published system. But it isn't the plant. It's the plumbing.
Why would a store sell below cost?
Price wars and loss leaders, mostly. And one thing that isn't speculation: Ontario's regulator fined retailer Cannabis Xpress $100,000 (reduced from $200,000) for what the AGCO called pay-to-play disguised as a "data program," involving agreements with at least 61 licensed producers. Producers paying stores for treatment they're not allowed to pay for. That thread is open on our story board as The Inducement File.
Your two-minute routine
1. OCS price ÷ 1.57 = the floor. 2. hibuddy.ca = the map. 3. Decide with your eyes open — and remember the honest note: your independent shop can't always chase chain prices, and sometimes the extra couple of bucks buys you the budtender who actually has time for your questions. Informed is the whole point.
