The Notarius Edge

You know Notarius through our digital signature and our reputation. However our real added value goes far beyond these elements. Here is the real Notarius edge.

Strong origins
Notarius is a reputable company founded in 1996 by the Chambre des notaires du Québec, a professional body and member of the Federation of Law Societies of Canada. Notarius is now partnered with over 35 professional bodies and associations. This recognition is unparalleled in the professional sector.

Impeccable credentials
For documents that require the highest reliability and those that require real longevity of use, including land registry documents, engineering plans and estimates or bank payment instructions, Notarius provides solutions with the highest international standards: Notarius is certified ISO 9001:2008 (Quality Management System) and ISO 27001:2013 (Information Security Management System). This is why we invite our partners and customers to expand the application of the PDF/A format, itself derived from the ISO 19005 standard. Highly customer-oriented.

Simply issuing digital signature certificates is not enough. Unlike typical certification authorities, Notarius is not confined to only issuing these certificates. We also offer complementary solutions. For example, Notarius innovated by creating ConsignO , which is included with subscriptions to CertifiO for Professionals  and CertifiO for Employees. Notarius also offers server versions of CertifiO and ConsignO. Lastly, Notarius also meets the needs of employers with VerifiO , which allows for the efficient and extremely low-cost verification of digitally signed documents.

Extensive and globally recognized expertise

To verify document reliability, you must ensure the origin, integrity, authenticity and longevity of a document. In terms of Information and Communication Technologies (ICT), you must combine three areas of expertise in order to perform this verification: The digital signature, the PDF/A standard and the applicable law. Notarius is the only Certification Authority to combine extensive expertise in these three areas, and is therefore also recognized by the PDF Association and the Federation of Trusted Third Party.

Competitive prices

Notarius was founded as a non-profit organization (NPO) and its prices were set accordingly. When Notarius was continued as a commercial enterprise in 2012, prices did not increase; in fact, they decreased. When conducting a comparative analysis of the market, our partners and customers realized that they were unable to find alternative solutions offering a comparable level of document reliability for a similar or lower price.

Great value for you

Notarius was founded as a non-profit organization (NPO), and its prices were set accordingly. When we grew into a commercial enterprise in 2012, our prices did not increase; in fact, they became even lower than before. Our partners and customers know that only Notarius offers document reliability of this kind at such a great price.

Environmental responsibility and social engagement
We are working to create a greener and less polluted world through the dematerialization of official documents. We have also been certified carbon neutral since 2013, demonstrating our efforts to reduce our greenhouse gas (GHG) emissions. Similarly, our history as an NPO perpetuates our values through our volunteer programs. To learn more about our values and social engagement, please visit our About page.
