Every small-cap investing guide tells you to “do your due diligence.” Almost none of them tell you where that actually happens, or what to click once you get there. This is that part.

The tool is called SEDAR+. It’s free, it’s public, and every company trading on the TSX, TSXV, or CSE has to file through it. Most retail investors have never opened it. That’s not a knock on anyone, the interface isn’t exactly built for casual browsing, but it’s also the single biggest gap between “I read a stock promotion online” and “I actually looked at what the company itself is legally required to disclose.”

If you’ve read our exchange guide, this is the flashlight. Here’s how to actually turn it on.

What SEDAR+ Actually Is

SEDAR+ replaced the original SEDAR system on July 25, 2023, after a couple of delays pushed the launch back from its original June date. It’s run by the Canadian Securities Administrators, the umbrella group representing provincial securities regulators, and it consolidated several older systems, SEDAR itself, the national Cease Trade Order database, and a few others, into one platform.

Every reporting issuer in Canada has to file here. TSX, TSXV, and CSE companies alike. No account, no login, no fee to search and read. You just go to the site and look.

One rough patch before you go in: the launch had real technical problems, performance issues, search restrictions, and filing errors that frustrated filers and researchers for months afterward. Most of that has been ironed out, but if a search feels clunkier than a modern website should, that’s the system’s history, not something you’re doing wrong.

Finding a Company’s Profile

Search by company name or ticker. Sounds simple, and mostly is, but a couple of things trip people up the first time.

Companies rename themselves constantly in this world, a mining company pivots to lithium and changes its name, a shell gets reverse-merged into something completely different. If you search an old name and get nothing, try the current ticker instead. And if multiple similarly-named entities show up, check the exchange and the reporting jurisdiction before you assume you’ve got the right one. It happens more than you’d think, especially with generically-named shells.

Once you’re on the right issuer profile, you’ll see a running list of every document that company has filed, going back to whenever they started reporting.

The Documents That Actually Matter

There’s a lot on that list. Most of it you can ignore. Here’s what’s actually worth opening.

Annual Information Form and audited annual financials. The yearly baseline. This is the most complete single snapshot of the company you’ll find, business description, risk factors, financial statements with an auditor’s opinion attached. AIFs are required under Part 6 of National Instrument 51-102 for most reporting issuers, though some venture issuers have modified requirements. Start here if you’re looking at a company for the first time.

Interim financial statements. Quarterly. These are how you catch a burn rate trend before year-end rolls around and tells you all at once. A company that looked fine in Q1 and is suddenly burning twice the cash by Q3 is telling you something, and you’d miss it entirely if you only ever checked the annual filing.

MD&A, Management’s Discussion and Analysis. Honestly, the most human-readable document in the entire filing set, and the one most beginners skip because it sounds boring. It’s management’s own plain-language walkthrough of what happened and why. Annual MD&A has to cover the two most recently completed financial years, so you get built-in context, not just a single snapshot. If you only read one document per filing, make it this one.

Material change reports. Companies have to file one within ten days of anything materially changing about the business, a new deal, a management shakeup, a financing, a lawsuit. The ten-day window matters. A company that’s slow to file these, or that seems to be stretching what counts as “not material” to avoid disclosing something, is worth a second look.

Prospectuses and offering documents. What a company has to tell you when it’s raising money from the public. Dense, but this is where dilution terms, use of proceeds, and risk factors around a specific financing actually live.

Technical reports for mining companies, the NI 43-101 filings, also live in SEDAR+, but reading those properly is its own skill entirely. That’s a dedicated article on its own later in this series.

A Ten-Minute First Pass

If you’re short on time and just want a gut check on a company, here’s the order that gets you the most signal fastest:

Open the most recent MD&A first. Read it in plain language, ignore the numbers for a second, just get the story of what management says is happening.

Then pull up the financial statements from the same period and check the story against the numbers. Does the cash position support what they’re claiming? Is revenue actually moving the direction the narrative suggests?

Then scan for any material change reports filed in the last few months. Anything recent that changes the picture you just built.

Ten minutes, three documents, and you already know more than someone who bought the stock off a forum post.

What Red Flags Look Like in the Filings Themselves

A full red-flags breakdown is coming in its own article, but a few things are worth flagging here since you’ll see them the moment you start actually reading filings.

Going concern language in the auditor’s notes. This is auditor-speak for “we have real doubt this company can keep operating without more financing,” and it shows up more often than you’d expect in early-stage companies. Plenty of legitimate small caps carry this note while they build toward revenue. Understand what it actually means before you dismiss it, or before you panic about it.

Frequent auditor changes. One change might be nothing. A pattern of changes is worth asking why.

Repeated related-party transactions. Deals between the company and its own directors, officers, or major shareholders. Not illegal, and not automatically a problem, but worth tracking if it keeps happening.

Filing dates that keep slipping later. A company that used to file on time and starts filing late, quarter after quarter, is telling you something about what’s happening internally, even if the filing itself doesn’t say it directly.

Key Takeaways

• SEDAR+ is free, public, and every TSX, TSXV, and CSE company has to file through it.
• The MD&A is the most useful single document for a plain-language read of what’s actually happening.
• Material change reports have a ten-day filing deadline, and how promptly a company files them is itself a signal.
• A focused ten-minute pass, MD&A, then financials, then recent material change reports, beats reading zero filings by an enormous margin.
