Document reliability, our core business for the last two decades

Established in 1996 by the Quebec Board of Notaries, Notarius provides solutions that safeguard the long-term reliability of electronic documents.

Since its creation, Notarius has positioned itself as a Canadian market leader by ensuring the integrity and authenticity of official documents for transactions between a wide variety of professionals, business partners, clients, municipalities and government agencies.

Notarius issues and manages trusted digital signatures. This cyber security initiative is designed to protect the public and enable professionals to sign electronic documents with the same legal value as a paper document signed by hand.

Used by 30 professional associations in Canada, over 4000 companies and thousands of professionals across the world, Notarius’ digital signature certificates are a secure, effective and economical solution that is now an integral part of many trades, professions and organizations.


Since 1998, the Notarius Certificate Authority (CA), based on a Public Key Infrastructure (PKI), has been recognized and trusted by government agencies.

In 2007, the Notarius Certificate Authority was the first in North America to be certified ISO 27001 (Information Security Management).

Notarius is also certified ISO 9001 (quality management) and is a member of leading organizations in the field of trusted third parties (FNTC, DIACC and the PDF Association).

Notarius is the only Canadian company that provides digital signatures recognized by Adobe (Adobe Approved Trust List – AATL) and eIDAS (electronic IDentification Authentication and trust Services).

All of these certifications attest to Notarius’ expertise and the reliability of its signature solutions.
