A TSXV junior grinds higher for a week on no news. Then a press release lands: a fund or a mining company announces it has acquired securities of the issuer and now holds more than 10%. That release is part of the early warning report system. If you searched “early warning report Canada meaning”, this post covers the rules, how they compare to US filings, where to find the report on SEDAR+, and how to tell a strategic buyer from a financier who picked up units in a placement.
An early warning report in Canada is a securities filing and press release required when a holder comes to own or control 10% or more of a class of voting or equity securities of a Canadian reporting issuer. Quick note: this page covers that securities-law report, not Early Warning Services, the US company that handles bank account reporting.

What is an early warning report in Canada?
An early warning report is a public filing, plus a press release, that anyone who comes to own or control 10% or more of a class of voting or equity securities of a Canadian reporting issuer must make, so the market knows a significant holder exists.
The trigger sits in National Instrument 62-104 (Ontario has parallel provisions in its Securities Act). The detail on what the report must contain, and the alternative system for institutions, sits in National Instrument 62-103, the CSA’s early warning instrument. The report itself is Form 62-103F1.
It applies to reporting issuers, not to exchanges. TSX, TSXV and CSE companies are all covered. If you trade mostly Canadian names, our Canadian small caps hub pulls the related filing guides together.
What triggers an early warning report?
Crossing 10%, then every further 2% change up or down, and dropping back below 10%. Here is the full list:
- Crossing 10%: issue a press release promptly, and no later than the opening of trading on the next business day. File the report within two business days.
- Each additional 2% increase: a new release and report.
- Each 2% decrease: decrement reporting was added in the CSA’s 2016 amendments, so sellers have to show up too.
- Falling below 10%: a final report.
- A change in a material fact in a previous report, such as a new stated plan.
- During someone else’s formal take-over bid: the threshold drops to 5%.
The convertible math catches a lot of traders out
The holder counts securities it can acquire within 60 days: warrants, options, convertibles. But only its own convertibles go into the denominator, not everyone else’s. That is the “partially diluted” basis, and it is why a placement buyer holding warrants can cross 10% while owning well under 10% of the shares outstanding.
The short buying pause
A holder below 20% generally cannot buy more of that class until one business day after the report is filed. It is a speed bump, not a wall.
What is the AMR alternative for institutions?
The alternative monthly reporting (AMR) system lets eligible institutional investors file monthly instead of issuing an immediate press release.
Eligible institutions include financial institutions, pension funds, mutual funds and investment managers. Under AMR they report within 10 days after the end of the month in which they crossed a reporting threshold, using Form 62-103F3. They lose eligibility if they intend to make a take-over bid or propose a transaction that would give them control, and in certain contested proxy situations.
The trader takeaway: an AMR filing from a large fund manager shows up weeks later and is designed for passive holders. Do not treat it as fresh news.
Early warning report Canada vs US Schedule 13D and 13G
If you trade cross-listed names, you will see both systems. The US uses a 5% threshold and has no press release requirement. US deadlines below reflect SEC amendments that took effect in 2024. See Investor.gov on Schedules 13D and 13G.
Cross-listed names may also skip the 8-K entirely on EDGAR. Our guide on the 6-K filing used by foreign private issuers shows where their offering news appears instead.
| Canada early warning | US Schedule 13D | US Schedule 13G | |
|---|---|---|---|
| Ownership trigger | 10% (5% during another party’s bid) | More than 5% | More than 5% |
| Who files it | Holders not using AMR | Activists, strategic buyers, anyone not eligible for 13G | Passive investors, qualified institutions, exempt investors |
| Initial deadline | Press release by next business day’s open; report within 2 business days | 5 business days | 5 business days for passive investors; 45 days after quarter end for qualified institutional and exempt investors |
| Updates | Each 2% change up or down, falling below 10%, material changes | Within 2 business days of a material change (a 1% change is deemed material) | 45 days after quarter end for material changes; faster once holdings pass 10% |
| Press release | Required | Not required | Not required |
| Institutional alternative | AMR, monthly | 13G is the alternative | n/a |
| Convertibles counted | Acquirable within 60 days | Acquirable within 60 days | Acquirable within 60 days |
| Where to find it | SEDAR+ | EDGAR | EDGAR |
How do you find an early warning report on SEDAR+?
Search the issuer on SEDAR+ and look for documents labelled as early warning reports, then match them to the holder’s press release.
If the new holder’s arrival changes the business itself, the issuer may also file its own disclosure, so it helps to know how to read a Canadian material change report.
- Go to SEDAR+ and search for the company.
- Open its filings, sort by date and scan for “early warning report” document types. The holder may also have its own profile, so search its name if nothing shows.
- Read the matching press release. They are often titled “announces acquisition of securities of” or “files early warning report”.
- Cross-check SEDI. A holder of more than 10% of the voting securities is generally an insider and has to file insider reports, which show trade-level detail.
If you are new to the SEDAR+ search screens, our step-by-step SEDAR+ guide walks through filters and document types.
Strategic accumulator or financier: how do you tell?
Look at how the shares were acquired, whether warrants are involved, and what the purpose section actually says.
Hypothetical example: the 13.8% holder who owns 7.4%
Hypothetical: a junior has 100 million shares out. A fund subscribes for 8 million units in a private placement, each unit being one share plus one warrant. After closing there are 108 million shares out.
- Undiluted: 8M / 108M = 7.4%
- Partially diluted: (8M + 8M) / (108M + 8M) = 13.8%
The release headline says “over 10%”. Social media reads it as a big buyer taking a stake. In reality this is a financier holding discounted paper and warrants that can become overhang, with shares that become sellable once the hold period ends.
Checklist: what to read in the report
| Signal | Leans strategic accumulator | Leans financier |
|---|---|---|
| How acquired | Open market or block purchases | Private placement subscription |
| What was acquired | Common shares | Units with warrants |
| Undiluted vs partially diluted | Close together | Large gap from warrants |
| Price paid | At or above market | Placement price, often a discount |
| Purpose section | Specific: board seat, partnership, possible transaction | Boilerplate “investment purposes”, may increase or decrease |
| Side agreements | Investor rights, participation or nomination rights | Usually none |
| Who the holder is | Industry peer or producer | Fund, merchant bank, finance vehicle |
| Follow-up filings | 2% increments up | 2% decrements and a drop below 10% |
Is an early warning report bullish or bearish?
Neither by itself. It tells you who holds a big block, and the details decide whether that block is support or future supply.
A peer building a stake in the open market takes shares off the float and may signal deeper interest. A financier sitting on cheap shares and warrants is potential supply. A ticker rips 60% in a week, then a decrement release shows a holder dropped from 14% to 11%: someone sold into the run. That is information you can use to size risk, not a signal to act on.
On US names the equivalent work is reading 13D/13G filings and insider forms. Our guide to reading Form 4 insider buying covers that side.
FAQ
Is an early warning report the same as an insider report?
No. The early warning report discloses the stake and purpose on SEDAR+. Insider reports on SEDI show individual trades. A 10% voting holder usually files both.
Does a 10% holder have to say why they bought?
Yes, the report includes a purpose section and any plans. Much of it is boilerplate, so look for specifics like board nominations or transaction plans.
Why does a fund sit at 9.9% and never file?
Staying under 10% avoids the filing. Some financiers also use exercise caps on warrants so their partially diluted stake stays below the threshold.
Does this apply to CSE companies?
Yes. The regime applies to Canadian reporting issuers regardless of whether they list on the TSX, TSXV or CSE.
What Form 62-103F1 asks the filer to disclose
Form 62-103F1 walks the filer through a fixed set of items, so every report reads in roughly the same order. The headings in the form are:
- Security and reporting issuer
- Identity of the acquiror, including any joint actors
- Interest in securities of the reporting issuer (number and percentage held)
- Consideration paid (how and at what price)
- Purpose of the transaction
- Agreements, arrangements, commitments or understandings with respect to securities of the issuer
- Change in material fact
- Exemption relied on, if any
- Certification
The form text sits with NI 62-103 on the OSC site.
What changed in 2016
The 2016 amendments kept the reporting threshold at 10% but made the regime more detailed. The CSA had floated lowering it to 5%, then decided against it. What did change: reporting on each 2% decrease, a report when a holder falls below 10%, more disclosure in the report (including the purpose section and related derivatives or securities lending arrangements), and tighter limits on who can use AMR, such as investors soliciting proxies on certain matters. The CSA notice of amendments is published alongside NI 62-103.
How are equity swaps and derivatives treated?
Cash-settled equity swaps generally do not count toward the 10% threshold, because the holder has no right to acquire the underlying shares. Derivatives that let the holder get shares within 60 days, like warrants or convertibles, do count. The companion policy also says the CSA may look closely at anyone using derivatives to build an economic stake while avoiding a report. The report has to disclose related derivatives the holder has. No new derivatives rule is in force as far as this page covers, so check the CSA site for any current proposals.
Where do traders go wrong with these reports?
Common misreadings in trader forums
Most misreads come from skipping the actual filing. The usual ones:
- Treating the partially diluted percentage as shares owned, when warrants are inflating it.
- Treating an AMR filing as fresh buying, when it can show up weeks after the fact.
- Reading boilerplate “investment purposes” language as a takeover hint.
Primary sources
These are the texts the rules come from:
- NI 62-104 Take-Over Bids and Issuer Bids (the trigger)
- NI 62-103, Companion Policy 62-103CP and Form 62-103F1
If you are new to this, read Companion Policy 62-103CP first. It is the CSA explaining its own rules in plainer language.
More questions traders ask
Who files the report on SEDAR+?
The acquiror, or an agent such as its law firm, files the report and the news release on SEDAR+. The issuer does not file it for them. This page is written for traders reading filings, so for the actual filing steps use the filer resources on SEDAR+.
Is there a filing fee?
Any fee is set by each province or territory’s own fee rules, not by the national instrument. Check the fee schedule of the regulator where the filing is made, linked from the CSA site.
What happens if a holder does not file?
Not filing is a breach of provincial securities law, and the regulators can enforce it. Provincial securities acts give them tools like administrative proceedings and public interest orders, including cease trade orders. The outcome depends on the regulator and the facts.
Can promoters spin an early warning release?
The filing is a regulatory disclosure, but how people talk about it is another story. If someone hypes an “over 10% stake”, open the actual report on SEDAR+ and compare undiluted and partially diluted numbers. In the hypothetical above, 13.8% on paper was 7.4% of shares owned.
