A junior explorer on the TSXV announces a financing. Hard-dollar units at one price, flow-through shares at a higher price. The stock pops on the “fully funded drill program” headline, then bleeds for weeks. If you trade Canadian juniors, flow-through shares are a big reason that pattern keeps showing up. This post covers what they are, why they so often turn into supply, and where to find them in the filings before you size into a name.
Flow-through shares are new shares sold by a Canadian mining or oil and gas explorer that hands its eligible exploration deductions to the buyer under section 66 of the Income Tax Act. The buyer usually pays a premium for that tax benefit. For traders, the main point is that many holders are tax-motivated and willing to sell once the shares become free trading.

What are flow-through shares?
Flow-through shares are common shares issued by a Canadian resource company that passes (“renounces”) its eligible exploration spending to the buyer, who deducts it on their own tax return.
The rules live in the Income Tax Act, section 66. The issuer has to be a principal-business corporation, which in practice means mostly mining and oil and gas explorers. It agrees to spend the money on qualifying Canadian exploration expenses (CEE) and, in some cases, development expenses, then renounces those deductions to the shareholders.
Why would a company give away its deductions? Because an explorer has no revenue. Its tax losses are worth almost nothing to it. To a high-income Canadian taxpayer, the same deductions are worth real money. Grassroots mining exploration can also qualify for the federal Mineral Exploration Tax Credit, certain critical minerals have a separate federal credit, and some provinces add their own. So the company sells the tax benefit along with the stock.
Why do flow-through shares sell at a premium?
The buyer gets the stock plus a deduction, so they will pay more than a regular buyer. You see it right in the press release. A hypothetical example: hard-dollar units at $0.20 and flow-through shares at $0.26 on a stock that closed at $0.21. That $0.26 looks like a vote of confidence. It is mostly the price of a tax deduction.
Why do flow-through shares create selling pressure?
Many flow-through buyers get their return from the tax deduction, not the share price, so they have little reason to hold once the shares are free to trade.
That one sentence explains a lot of ugly charts. Here are the mechanics behind it.
The tax math changes the exit
Flow-through shares have a deemed cost of nil for tax purposes. When the holder sells, the whole sale price is treated as a capital gain, while the deduction they already took came off ordinary income. Depending on their situation, a holder can sell below the price they paid and still come out ahead after tax. Individual cases vary, but the point for you is simple: these holders are not anchored to their entry the way you are. The flow-through price is not support.
The hold period ends on a date you can calculate
Flow-through shares sold by private placement are usually subject to the standard four-month hold under Canadian resale rules. They become free trading four months and a day after closing. If a big flow-through tranche closed in one block, a lot of tax-motivated holders get liquidity on the same day. We cover the date math in TSXV private placement hold periods.
Charity flow-through puts shares with a back-end buyer
In a charity flow-through structure, the investor buys flow-through shares, donates them to a registered charity, and the charity sells them to a pre-arranged buyer, often at or below market. The donor stacks a donation receipt on top of the flow-through deduction. The final holder paid a low price and is often looking for a quick exit. That is why charity deals can show the biggest headline premium and still lead to the heaviest supply.
Whether there is a wait depends on the exemption. Shares issued by prospectus or under the listed issuer financing exemption (LIFE) generally carry no hold period, so supply can hit right after closing. Always check the release.
Seasonality and funds stack on top
Investors want deductions in the current tax year, so flow-through raises tend to cluster late in the year, right when Canadian tax-loss selling also hits small caps. Flow-through limited partnerships pool investor money across many placements and later typically liquidate or roll their holdings, which is another source of selling that has nothing to do with the drill results.
The money cannot pay the bills
Flow-through cash is earmarked for eligible exploration. It cannot fund salaries, office costs or general overhead. A company that just raised flow-through money may still need a hard-dollar raise soon for working capital. A flow-through close does not mean the dilution is over. If you want the full playbook on spotting that, read how to tell if a stock is diluting.
When the flow-through money finally turns into drill results, the next document worth reading is the resource estimate, so learn how to read an inferred vs indicated resource in a junior miner’s estimate.
Hard-dollar vs flow-through vs charity flow-through
| Hard-dollar placement | Flow-through placement | Charity flow-through | |
|---|---|---|---|
| Price vs market | Usually at or near market, often with warrants | Premium to the hard-dollar price | Largest headline premium; back-end buyer often at or below market |
| Use of funds | Any purpose, including overhead | Eligible Canadian exploration only | Eligible Canadian exploration only |
| Resale | Four-month hold if private placement; none if LIFE or prospectus | Same rules | Same rules; check which exemption was used |
| Holder motive | A view on the stock | Tax deduction plus some stock exposure | Back-end buyer wants the spread and an exit |
| What to watch | Warrant overhang, hold expiry | Hold expiry date, year-end timing | Supply soon after the shares are tradeable |
Where can you see flow-through shares in the filings?
You find them in the company’s news releases, its documents on SEDAR+, the exchange bulletin, and the notes to its financial statements.
- The announcement release. Search for “flow-through”, “FT units”, “charity flow-through”, “premium”, “CEE” and “renounce”. Note the flow-through price, the hard-dollar price and the last close.
- The closing release. This gives the actual number of shares issued and often states the hold period expiry date in plain words. That date goes in your calendar.
- SEDAR+. On sedarplus.ca, pull the news releases, any material change report, the LIFE offering document if the deal used that exemption, or the prospectus supplement if it was a prospectus deal. Our step-by-step guide to checking dilution on SEDAR+ walks through the search.
- The exchange bulletin. On the TSXV, the exchange accepts the placement for filing, which confirms final numbers.
- Financial statements and MD&A. Look for a “flow-through premium liability” or a flow-through spending commitment. It tells you how much exploration money still has to be spent, and by when.
A hypothetical walkthrough
Hypothetical: a junior closes 12 million flow-through shares at a premium, issued by private placement, in mid-December. You mark four months and a day later. The stock drifts below the flow-through price by spring. A lot of traders assume those holders are “underwater” and will defend their price. After tax, many of them may not be underwater at all. Around the free-trading date, you compare volume to the recent average, watch the tape for size hitting the bid, and check whether a hard-dollar raise has been announced since. None of that tells you the stock will drop. It tells you where the supply could come from.
Checklist before you trade a junior after a flow-through raise
- Is it plain flow-through or charity flow-through?
- Which exemption: private placement, LIFE or prospectus? That decides when shares can trade.
- What is the exact free-trading date, and how big is the tranche relative to the float and daily volume?
- How much hard-dollar cash does the company have for overhead? Is another raise likely?
- Is it late in the year, when flow-through deals and tax-loss selling overlap?
- Are there warrants attached to the units that add a ceiling?

FAQ
Are flow-through shares good or bad for a stock?
Neither by default. They fund exploration without the company paying cash for the tax benefit, which can be a real positive. But they add shares, and many holders are tax-motivated sellers. Judge the deal size, structure and timing, not the headline premium.
When do flow-through shares become free trading?
If issued by private placement, usually four months and a day after closing. If issued by prospectus or under LIFE, generally right away. The closing release and SEDAR+ documents tell you which applies.
Can US investors buy flow-through shares?
The deduction only has value to someone paying Canadian income tax, so these deals are aimed at Canadian taxpayers. US traders can still trade the common shares on the market once they are issued, and they feel the selling pressure all the same.
Why do junior miners drop after a flow-through financing?
Common reasons: new supply, holders who can sell below their purchase price and still profit after tax, back-end buyers in charity structures, and year-end tax-loss selling. Sometimes it is just the drill results. Check the filings before you assume.
CEE vs CDE: what gets renounced?
Most flow-through money is spent on Canadian exploration expenses (CEE), which are generally fully deductible by the buyer. Canadian development expenses (CDE) can also be renounced, but they are deducted on a declining-balance basis, so the deduction is spread over several years. A look-back rule can let an issuer renounce exploration spending in one year even if it actually spends the money during the following calendar year. The details are in ITA section 66 and the CRA flow-through shares guidance.
How do the METC and the critical mineral credit work?
The Mineral Exploration Tax Credit is a non-refundable federal credit on eligible grassroots exploration renounced to individuals. The critical mineral exploration tax credit is a separate federal credit at a higher rate for eligible critical minerals. Claiming either credit reduces the buyer’s CEE pool the following year. Quebec also offers extra provincial deductions for exploration done in Quebec, so check current Revenu Québec rules before relying on them.
Hypothetical after-tax walkthrough
This is illustrative only and not tax advice. Say a buyer pays $0.26 per flow-through share, the same hypothetical premium price used above. They deduct roughly that amount from ordinary income at their marginal rate. Their cost base is nil, so if they later sell at $0.20, the whole $0.20 counts as a capital gain, and only part of a capital gain is taxable. After combining the deduction, any credits and the tax on the gain, a high-bracket buyer can end up ahead even though $0.20 is below $0.26.
The actual after-tax cost depends on the buyer’s provincial marginal rate and any provincial credits. We are not going to quote a calculator. CRA, provincial tax resources or a tax professional are the right places for that.
Does alternative minimum tax affect flow-through buyers?
It can. Large flow-through deductions combined with capital gains can bring alternative minimum tax into play. The AMT rules were changed recently, so older articles may be out of date. Check current CRA guidance or ask a tax professional.
Flow-through LPs vs buying flow-through shares directly
A flow-through limited partnership spreads money across many issuers, while a direct buyer holds one company and carries all of its exploration risk. LPs charge management fees, and they typically liquidate their holdings or roll them into a mutual fund on a set schedule. Direct holders decide for themselves when to sell after the hold expires. For traders, the LP point matters because a fund exit can put supply into many junior names at once, regardless of drill results.
Who can buy flow-through shares?
Private placement flow-through shares are usually sold through investment dealers to buyers who qualify under a prospectus exemption, most often the accredited investor exemption. Non-accredited Canadian investors typically get access through prospectus offerings (including bought deals), LIFE offerings, or flow-through LPs sold by prospectus through advisors. Eligibility depends on the exemption the issuer uses, so read the offering document. More on how these raises are structured is in our TSXV private placements guide.
What issuer checks should you add to the checklist?
- Is the project grassroots or advanced?
- How much flow-through spending is still committed, and by what deadline? Check the MD&A.
- How often has the company raised before? Its SEDAR+ history shows the pattern.
- Is the property in Canada? Flow-through money has to be spent on Canadian exploration.
More questions traders ask
What are the pros and cons for the buyer?
The pros are the deduction and, for eligible spending, possible federal or provincial credits. The cons are premium pricing, illiquidity during the hold period, single-issuer exploration risk, possible AMT, and a nil cost base that makes any sale fully a capital gain. None of that says anything about whether the stock goes up.
Why did my junior drop after the flow-through close?
Usually because new supply showed up from holders who do not need a higher price to come out ahead. Check the exemption, the free-trading date, whether it was a charity deal, and whether LP or tax-loss selling overlapped. If you want to talk it through with people who read filings, the free Discord is open.
Are flow-through shares a tax shelter scheme?
No. They are a legislated incentive under ITA section 66, not a loophole. Be careful with anyone promising guaranteed after-tax returns or unusual donation arrangements, and read the CRA guidance. The structure is Canada-specific. Australia has its own Junior Minerals Exploration Incentive, which works differently.
