Everything I learned about eSignatures and how valid they really are
The Ten-Minute Test That Tells You Whether Your Electronic Signature Is Worth Anything
Open the last contract a customer signed with you. Look at the electronic signature at the bottom of it.
Now, without emailing anybody and without asking a co-founder, produce five things: the moment it was sent, the address it went to, the moment it was opened, the deliberate act the signer performed to sign it, and proof the file has not changed since.
Ten minutes on the clock.
Most people reading this cannot do it.
They have a PDF with a name on it, sitting in a folder, and a strong feeling that everything is fine.
Everything is fine right up until a client stops paying and says they never signed anything, at which point section 31.1 of the Canada Evidence Act hands the burden of proving that document is what you claim it is to exactly one party.
You.
Every electronic signature here is legal, which is exactly the problem
Part 2 of PIPEDA defines an electronic signature as letters, characters, numbers or other symbols in digital form incorporated in, attached to or associated with an electronic document.
That is the entire bar.
Every province has its own statute, most modelled on the Uniform Electronic Commerce Act, and they all land in the same place. Quebec does not even tie the definition to a medium.
So a name typed into a text box counts. A scribble drawn with a trackpad at eleven at night counts.
Nothing you are doing is illegal, and nobody is going to void your contract for being digital.
There is a second tier almost no founder touches.
The Secure Electronic Signature Regulations, SOR/2005-30, describe a narrow species of signature: a hash of the document, a private key, a certificate from a certification authority the Treasury Board recognizes.
Land in that tier and evidentiary presumptions attach to your signature.
Stay in the baseline tier, where every commercial contract on earth actually lives, and you get no presumption whatsoever.
That gap is the whole story.
Generous law on validity, silent law on proof, and a burden that lands on the party who wants their money.
It is a design choice, and a sensible one, because legislators did not want to freeze a technology into a statute.
The cost of that flexibility gets pushed downstream, onto whoever picked the tool.
Which is you, probably at two in the morning, comparing three pricing pages while trying to get a client onboarded before the weekend.
Outside Canada the vocabulary changes and the exposure does not.
ESIGN and UETA in the United States, the eIDAS tiers in Europe, the same bargain everywhere: electronic form alone will not kill your contract, and the evidence is your problem.
A thumbs-up emoji, 87 tonnes of flax, and $82,200
March 2021.
A grain buyer in Saskatchewan and a farmer he had been trading with since 2012 settle a price on the phone, the way they always do.
The buyer drafts the contract, 87 metric tonnes of flax at $669.26 a tonne, signs it, photographs it with his phone and texts the picture over with four words:
please confirm flax contract.
The farmer sends back a thumbs-up emoji. 👍
Nothing about that exchange looks like contract execution.
No platform, no signing ceremony, no click-to-accept screen, no audit trail in any sense a vendor would recognize.
Two people who trusted each other, doing what they had done dozens of times.
November arrives.
No flax.
The market has moved against the buyer, and he sues.
The farmer's defence is the one everybody would reach for: the emoji meant message received, nothing more, and the real contract was supposed to follow by fax for review.
In South West Terminal Ltd. v Achter Land and Cattle Ltd., 2023 SKKB 116, decided June 8, 2023, the Court of King's Bench disagreed and awarded $82,200.21.
The reasoning is the part to sit with.
A signature does two jobs, the court said: it identifies the signer, and it conveys acceptance.
The emoji came from a phone number that belonged to one specific person.
The two of them had a decade of history confirming contracts exactly that way, sometimes with nothing more elaborate than "ok".
That record carried the day.
Now flip it.
Two characters on a screen became enforceable because a mountain of surrounding evidence propped them up.
Your beautifully typeset PDF with a cursive font signature has none of that.
Contrary to the way this gets discussed, the question was never whether your signature is valid.
It is what stands behind it when somebody pushes.
| What you have to establish | Where the requirement comes from | What your system must produce | What a free PDF signer gives you |
| --- | --- | --- | --- |
| The document is what you say it is | Canada Evidence Act, section 31.1 | A record tying the file sent to the file signed | The file, and nothing else |
| The storage system has integrity | Canada Evidence Act, sections 31.2 and 31.3 | Evidence the system worked and was not tampered with | A folder in someone's Drive |
| The signer is who they claim | Common law and provincial statutes | Delivery record, IP address, second factor by SMS or access code | Anyone holding the file can type any name |
| The signer meant to be bound | Case law, including 2023 SKKB 116 | Timestamped log of the act that applied the signature | No log at all |
| Both parties agreed to go electronic | Provincial statutes based on the UECA | Recorded acceptance of an electronic disclosure, with time and IP | Consent assumed, never captured |
| Nothing changed after signing | PIPEDA Part 2 integrity requirement | Tamper-evident seal or hash exposing later edits | Pages can be swapped and re-flattened |
| A presumption instead of a fight | SOR/2005-30 and section 31.4 | Digital signature with a recognized certificate | Not available at any price |
Every row is generated automatically by a competent platform as a side effect of hitting send.
You will never look at a single one until the day you need all seven at once.
Notice what the last column is not.
It is not a criticism of free tools for being cheap.
Flattening a signature image onto a page produces a perfectly valid document under every statute named above.
It just produces a document that says nothing about how it came to exist, which is the only thing anyone will ask about it.
The electronic signature bill is the cheap part of this decision
The cost complaints are legitimate.
DocuSign's entry tier runs around ten dollars a month billed annually and caps you at five envelopes a month.
The next tier sits near twenty-five dollars per user per month with a ceiling of roughly one hundred envelopes per user per year, call it eight a month, and SMS delivery and identity verification bill separately on top.
Push forty contracts a quarter with two people and the math genuinely stings.
The reflex is to drop to something free.
Understandable. Usually wrong.
Price per envelope is a number you renegotiate every twelve months over a twenty minute call.
Evidence quality is a number you test exactly once, retroactively, on the worst day of your quarter, against a contract you stopped thinking about eighteen months ago.
Which means the shopping list for an electronic signature platform is not a price column.
It is:
- an exportable certificate of completion;
- a tamper-evident seal;
- a second authentication factor for signers you have never met; and
- a straight answer about which country holds the records and which courts can reach them.
Ask what happens to the archive when you stop paying.
Ask whether you can pull a full audit trail yourself on a Sunday without opening a ticket.
Vendors who answer those crisply are telling you something a feature grid never will, and the ones who stall are telling you something too.
One more thing worth checking before you build the integration: provincial statutes still carve out wills, testamentary trusts, powers of attorney over someone's finances or personal care, and negotiable instruments such as promissory notes and cheques.
Ontario dropped its carve-out for land interests on July 1, 2015.
Other provinces did not.
If your product touches estates, lending or property, read your own province's list rather than a vendor's summary of it.
Go run the test
Set a timer.
Pull the contract.
Five facts, ten minutes, no help from anyone.
Pass it and you can close this tab and go back to shipping, because your paperwork will survive a bad customer.
Fail it and nothing bad happens today, which is precisely why nobody fixes this.
The bill arrives later, when someone with a lawyer works out that not paying you is cheaper than paying you, and the only thing standing between them and that conclusion is a record you never bothered to keep.
There is a version of this where the fix takes an afternoon.
Move the next batch of contracts onto something that:
- logs the send;
- verifies the signer;
- seals the file; and
- hands you a certificate you can export.
Backfill nothing, chase nothing, just stop adding to the pile of documents you cannot defend.
Six months from now the problem has shrunk to whatever you signed before today.
A farmer lost eighty-two thousand dollars over a gesture that took him half a second.
He lost because ten years of text messages said what he meant.
What do your files say about you?
