SAFEs and Convertible Notes in Canada: How They Work Before You Sign

A SAFE (Simple Agreement for Future Equity) and a convertible note are both ways for a startup to raise money without setting a price on the company's shares at the moment the cheque clears. That single feature — deferring the valuation question — is what separates them from a priced equity round, where the company and the investor agree on a specific price per share before any money changes hands.

Both instruments work the same way at a conceptual level: an investor gives the company cash now, and in exchange receives the contractual right to equity later, once specific things happen — most commonly, once the company raises a future priced round. Until that conversion happens, the investor typically holds no shares and has no voting rights. What they hold is a contract, not equity.

The two instruments differ in legal form. A SAFE, as originally created by the U.S. startup accelerator Y Combinator, is not a debt instrument — it carries no interest, and in its original American form has no maturity date or repayment obligation. A convertible note, by contrast, is structured as a short-term loan: it accrues interest, has a maturity date, and — unless it converts first — is technically repayable, which is a meaningful legal distinction even though most convertible notes are never actually repaid in cash.

For an early-stage company that has not yet reached the point where a professional investor is comfortable agreeing on a fixed valuation, both instruments offer a faster, cheaper way to bring in capital than negotiating a full priced round from scratch. That speed is also why the details matter: a founder who signs a SAFE or convertible note without understanding its mechanics is agreeing today to a formula that will determine how much of the company an investor owns tomorrow.

The practical difference between the two instruments shows up in what happens if nothing else happens — if the company never raises a subsequent priced round.

A convertible note has a maturity date. If the note has not converted by then, the note agreement typically sets out a defined path forward: the company may need to repay the loan (principal plus accrued interest), the parties may negotiate an extension, or the note may convert on its own pre-set terms — depending entirely on how the specific note is drafted. Because a convertible note is debt, an unpaid or defaulted note can, in principle, expose the company to remedies available to a creditor, not just an equity holder.

A SAFE in its original U.S. form has neither a maturity date nor interest, and there is no repayment obligation if a priced round never happens — the investor's downside, in that scenario, is that their investment never converts into anything. In practice, Canadian-adapted SAFE templates circulating in the Canadian market — including a version associated with Y Combinator's own Canada-specific documents and a separate version associated with the National Angel Capital Organization (NACO) — sometimes depart from that original U.S. design, for example by adding a maturity date. That is one of several reasons a founder should never assume that a document titled "SAFE" behaves exactly like the American original just because the name is familiar. Read the specific document in front of you; do not rely on what you remember reading about the U.S. version.

Two mechanics do almost all of the work in determining how a SAFE or convertible note converts into equity: the valuation cap and the discount rate. Both exist to compensate the investor for taking risk earlier, and with less information, than the investors who show up at the priced round.

A valuation cap sets a ceiling on the company valuation that will be used to calculate the investor's conversion price, regardless of what the company is actually worth when the priced round happens. If the company's value has grown substantially by the time of that round, the cap lets the earlier investor convert as though the company were still worth only the capped amount — producing more shares for the same invested dollar than a new investor buying in at the round's actual, higher valuation.

A discount rate works differently: rather than fixing a ceiling, it gives the SAFE or note holder the right to convert at a set percentage below the per-share price that new investors pay in the priced round, whatever that price turns out to be.

Many SAFEs and convertible notes include both a cap and a discount, with a mechanism — sometimes described informally as a "better of" provision — under which conversion uses whichever of the two produces a more favourable outcome for the investor. This is common market practice, but it is not a legal requirement and it is not universal: some instruments include only a cap, only a discount, or neither, and the exact conversion formula is a negotiated term that has to be read in the specific document, not assumed.

To make the mechanism concrete — and this example is entirely hypothetical, used only to illustrate how the formula works, not to suggest what any real deal should look like — suppose an investor puts $100,000 into a SAFE with a $5,000,000 valuation cap and a 20% discount. If the company later closes a priced round at a $10,000,000 valuation, the cap is more favourable to the investor than the discount, so the cap governs: the investor converts as though the company were worth $5,000,000, receiving twice as many shares for their $100,000 as a new investor paying the round's actual price. If, instead, the priced round values the company at only $4,000,000 — below the cap — the discount may instead produce the better outcome for the investor, converting at 20% below the round's price. Real caps, discounts, and the mechanics that combine them vary enormously by deal, stage, and negotiating leverage; none of the numbers above reflect a market standard or a typical deal.

Conversion is the moment the SAFE or convertible note stops being a contractual promise and becomes actual equity — specifically, shares of the company, typically a class of preferred shares carrying rights the company and its new investors negotiate at that time.

The events that trigger conversion are defined in the specific SAFE or note, but the most common ones are:

• A qualified equity financing — a future priced round that meets whatever minimum size or other threshold the instrument defines. This is the trigger every SAFE and convertible note is built around, and it is the scenario the valuation cap and discount rate exist to address.
• A liquidity event — typically a sale of the company or another change-of-control transaction. Most instruments address what happens to the investor's money if the company is sold before any priced round occurs, often giving the investor a choice between converting to equity immediately before the transaction or receiving a return tied to the amount invested.
• Dissolution — if the company winds down without ever raising a further round or being sold, the instrument typically defines the investor's position relative to other creditors and shareholders. That position is usually near the bottom of the priority stack for a SAFE and closer to ordinary unsecured debt for a convertible note, though this varies by drafting.
• Maturity, where the instrument includes one — more common in convertible notes, and sometimes present in Canadian-adapted SAFE templates even though the original U.S. SAFE does not include it.

None of these triggers is automatic in the way a light switch is automatic — the specific language of the instrument controls what happens, including any minimum-financing-size threshold that has to be met before a "qualified" financing actually triggers conversion. A founder should be able to answer, for every SAFE or note the company has outstanding, exactly what event converts it and exactly what formula applies when it does.

Yes — SAFEs and convertible notes are used regularly in Canadian startup financing, but they operate inside the same securities law framework as any other investment, and the paperwork commonly seen in the Canadian market is not identical to the original Y Combinator SAFE built for U.S. deals.

Two points matter here. First, on the contract side, more than one Canadian-adapted SAFE template circulates in the Canadian market, and they are not interchangeable. A widely used post-money-cap version, associated with Y Combinator's own Canada-specific documentation, calculates the investor's ownership percentage differently than a pre-money-cap version associated with the National Angel Capital Organization (NACO). The choice of template changes how dilution is calculated once a company has more than one SAFE outstanding, so a founder comparing offers — or receiving a document drawn from an investor's own template — needs to know which structure they are looking at, rather than assuming all SAFEs work the same way.

Second, on the regulatory side, issuing a SAFE or convertible note to an investor is, from a securities law perspective, a distribution of a security, and it needs to fit within a prospectus exemption under National Instrument 45-106 — Prospectus Exemptions, the framework Ontario and other Canadian securities regulators use to permit private capital raising without a full prospectus. In practice, most early-stage Canadian companies rely on exemptions such as the accredited investor exemption or the family, friends and business associates exemption, and the issuer is generally required to file a report of exempt distribution with the applicable securities regulator within 10 days of closing. None of this makes a SAFE or convertible note exotic — it is the same exemption framework that applies to essentially any private securities offering in Canada — but it does mean the transaction carries compliance steps that a plain reading of a U.S.-style SAFE template will not surface on its own.

The practical takeaway: a document that says "SAFE" on the cover page is not, by itself, evidence that it is the right document, correctly adapted for a Canadian company, on Canadian securities law terms. It is worth having Canadian counsel confirm the template and the exemption before money changes hands, not after.

By the time a term sheet or a signature-ready SAFE lands in a founder's inbox, much of the negotiating room has often already narrowed. Before signing, a founder is generally well served by being able to answer these questions about their own document:

• Is the cap pre-money or post-money? The two produce different dilution outcomes, particularly once more than one SAFE is outstanding, and the difference is not always obvious from a quick read.
• What exactly triggers conversion, and is there a minimum financing size? A future round smaller than the defined threshold may not trigger conversion at all under the instrument's own terms.
• Is there a most-favoured-nation (MFN) clause? Some SAFEs give the investor the right to swap into more favourable terms if the company later issues a SAFE or note with better terms to someone else — which can matter significantly if the company raises multiple rounds of bridge financing before a priced round.
• How many SAFEs or notes does the company already have outstanding, and on what terms? Each one dilutes the founders and every other instrument at conversion; a cap table that looks simple with one SAFE can become genuinely complex with four or five, each on different terms.
• What happens on a sale of the company before conversion? Confirm whether the investor converts, receives a return of their investment, or has an election, and understand which outcome is more or less favourable to the founders in a fast, modest-value exit.
• Does the instrument include board or information rights, side letters, or pro-rata rights for a future round? These are sometimes documented outside the main SAFE or note in a separate side letter, which is easy to overlook if only the primary document is reviewed.

None of this is a checklist for what terms a founder should accept — that is a negotiation, and reasonable terms vary by stage, sector, and the relative leverage of the parties. It is a checklist for understanding, with precision, what is actually being signed.

A SAFE or convertible note is often the first outside-money document a founder ever signs, frequently arriving with a deadline attached and little appetite, on either side, for a lengthy negotiation. That combination — high stakes, unfamiliar mechanics, and time pressure — is exactly when a plain-language understanding of the document matters most.

Lamba Law's startup financing practice reviews and negotiates SAFEs, convertible notes, and seed-stage term sheets for Ontario founders, translating the cap table math into a clear picture of what a founder is actually agreeing to before anything is signed. Because SAFEs and convertible notes so often intersect with what founders have — or have not — put in place among themselves, it is also worth confirming that your founder agreement and vesting terms are in order before you bring in outside capital; investors will ask.

We are also building a SAFE and convertible note modeler so founders can run their own cap table scenarios — different caps, discounts, and multiple outstanding instruments — before a call with a lawyer, not instead of one.
