What We Do

Digital signatures you can trust

Origin – Integrity – Authenticity – Longevity

Ensuring the long-term reliability of your documents

See why Notarius is the only trusted company capable of providing solutions to these matters.


  • Are you unsure if you’re respecting the laws and regulations governing the production of electronic documents?
  • Do you hesitate to destroy official paper documents once they’ve been scanned?

CertifiO, the trusted digital signature, fills these gaps and allows you to create a fully digital signature using a  legally reliable process.

Authenticating the signatory's identity

  • Do you want to feel confident about the authenticity of the documents you receive?
  • Would you like to be certain your documents have been signed by a professional with the right to practice?

CertifiO certifies the name of the signatory as well as his professional status (or the employment relationship). The software guarantees that a document is authentic by incorporating proofs of its origin and integrity into the document.

Tampered documents

  • Do you want to protect your documents to prevent them from being modified ?
  • Are you concerned with the integrity of the documents you receive?

The digital signature signals any alterations to signed documents. You can now be confident about the integrity of your documents.


  • Do you produce documents on your computer… and then print, sign and seal them in an envelope before mailing them?
  • Do you still use paper for your official documents?
  • Do you still sign your documents one at a time?
  • Are all of your processes digital, yet you still print your official documents to sign them or mail them  to your customers?

CertifiO, the trusted digital signature, helps shorten your business processes, making your process fully digital, and allowing you to get rid of hard copies.

Costs and delays

  • Does signing a document with your Montreal, Toronto and Vancouver divisions take over week?
  • Are your printing, handling, shipping and courier costs getting out-of-hand?

CertifiO and ConsignO can support several signatures on a document, without compromising its integrity or long-term reliability, and all at the speed of your Internet connection.

Longevity of your electronic documents

  • Are you unsure if your documents will be readable in 10 or 20 years?
  • Do you hesitate when choosing a file format in order to ensure the long-term reliability of your official documents?

ConsignO allows you to convert your documents to PDF/A standard, a badge of reliability to ensure that your documents will be readable for decades.


  • Are you overwhelmed with paper archives?
  • Are you considering building or renting additional storage space for your official documents or archives?
  • Do you need to guarantee the integrity of your files after scanning?

CertifiO and ConsignO allow stakeholders to establish a fully digital process while ensuring the integrity and longevity of electronic documents after scanning the paper archives.

Environmental impact

  • Do you use as much paper as you did 10 years ago?
  • Are your operations costly to the planet? (paper, courier, archives, etc.)
  • Are you looking for sustainable ways to go paperless?

CertifiO and ConsignO allow stakeholders to implement a fully digital process, all while reaping the benefits of a paperless approach. In addition, a digitally signed document using CertifiO has the same legal value as a hand-signed paper document.

Notarius — A company you can trust

Are you concerned about producing documents that will be readable and reliable for decades? Here are a few thoughtful suggestions to guide you when selecting a supplier.

  • If the company ceases operations or is acquired, how reliable will your documents be 5 years later? Will you be able to prove their authenticity?
  • Are digital signatures and long-term document reliability part of their core business values or are they on the sidelines? How many years of experience does the company have in this field?
  • What precautions does the company take to protect your digital identity, your personal information and your professional status?
  • Is the company certified ISO 27001 (information security),does it comply with the WebTrust for CA program and the Adobe Approved Trust List?
  • What is the company’s vision for the future? Is it active amongst core organizations such as the PDF Association, DIACC and the Fédération Nationale des Tiers de Confiance?
  • Does the company operate on Canadian soil? Is it a privately owned Canadian company?

Founded in 1996 by the Chambre des notaires du Québec, Notarius’ goal is to offer solutions that ensure the long-term reliability of official documents. Our motto: Origin – Integrity – Authenticity – Longevity.

Notarius is the only company in Canada to certify trusted identities and professional status throughout the entire life cycle. We are the only Canadian company that issues trusted digital signatures recognized by Adobe and Microsoft.
