SAFE vs. Convertible Note: Which One Should a Canadian Startup Use?

Key takeaways: A SAFE and a convertible note both let a startup raise money now and issue equity later, but a convertible note is debt — it accrues interest and has a maturity date — and a SAFE is not. Most Canadian pre-seed rounds default to a SAFE for speed and simplicity; a convertible note tends to show up when an investor wants debt-like protections attached to their money.

The two get confused constantly because they solve the same problem — pricing a round later, once there's a real valuation to price it against — with different legal mechanics underneath.

What a convertible note actually is

A convertible note is a loan. The company owes the investor the principal plus interest, and on a set maturity date the loan either converts into equity — usually at your next priced round, at a discount and/or capped valuation — or has to be repaid. Because it's debt, it sits on the balance sheet as a liability until it converts.

What a SAFE actually is

A SAFE isn't debt at all — see our guide to using a SAFE in Canada for the mechanics — it's an agreement for future equity with no interest and, in most versions, no repayment obligation if the triggering round never happens.

Four real differences that matter

• Maturity date. A convertible note has one — if the company hasn't raised a priced round by then, the note becomes due, or the parties renegotiate. A SAFE doesn't expire this way.
• Interest. A note accrues interest, which increases the amount that eventually converts into equity. A SAFE doesn't accrue interest.
• Balance sheet treatment. A note is debt until it converts. A SAFE is typically not treated as debt, which matters for how your balance sheet looks to a future investor or lender.
• What happens if there's no next round. A note's maturity date forces a conversation — repay, extend, or convert at whatever terms get negotiated. A SAFE, in most Canadian-adapted forms, simply keeps sitting on the cap table as a future claim until an actual trigger event happens.

Which one should a Canadian startup use

For a straightforward pre-seed or seed round with a friendly angel or a Canadian VC using CVCA-aligned terms, a SAFE is usually the simpler, faster document. A convertible note tends to make sense when an investor specifically wants the protections that come with debt — interest, a maturity date, sometimes a security interest — or when the company wants a forcing function: a real deadline that pushes toward a priced round rather than letting SAFEs stack indefinitely.

What this costs to get right

Ruby drafts either one for a flat $799, reviewed by a licensed Canadian lawyer before it goes to your investor — same price either way, so the decision should be about which instrument fits your round, not which one costs less.

Frequently asked questions

Can a startup use both SAFEs and convertible notes in the same round?

Yes, and it happens often on a rolling close — just make sure any MFN (most-favoured-nation) clause in the earlier instruments is checked against the terms of whatever comes later, so early investors don't end up worse off than later ones without you realizing it.

Does a convertible note need to be registered under Canadian securities law?

The same exemption analysis applies as with a SAFE — most pre-seed and seed notes rely on the accredited investor exemption under NI 45-106. The instrument type doesn't change which exemption you need; the investor's status does.

Which one do investors prefer?

It varies by investor, not by market default. Ask early rather than assuming — some funds have a template they always use.
