The Ontario Association of Architects partners up with Notarius to provide trusted digital signatures to their members

Notarius is proud to announce that its trusted digital signature solution, CertifiO, has been selected by the OAA.

“We are honored to welcome OAA as the newest association to select us for their digital transformation” says Claude Charpentier, CEO at Notarius. “Notarius provides our partners with a way to ensure the reliability of electronic documents while improving efficiency. Our partnership clearly demonstrates that OAA is a forward-thinking association making a conscious effort to remain current with industry trends.”

“For almost three years, the OAA Practice Committee has been examining safe and secure options for digital architectural seals to reduce the risk of fraud, prevent illegal practice and enhance protection of the public. One of the first proposals was to explore working with Notarius. Since then, we have looked at alternative products, watched the adoption of the company’s seal progress across Canada and came to the conclusion they would make a fine partner in this initiative,” states John K. Stephenson, President of OAA.


A leading expert in electronic signatures, digital signatures and long-term document reliability since 1998, Notarius is the only Canadian firm that issues trusted signatures recognized by Adobe (Adobe Approved Trust List – AATL) and eIDAS (electronic IDentification Authentication and trust Services). Notarius’ digital signature solutions are currently recognized and used by more than 35 professional associations across Canada, allowing thousands of professionals to sign and authenticate electronic documents with the same legal value as hand-signed paper documents.


The Ontario Association of Architects is a self-regulating organization governed by the Architects Act, which is a statute of the Government of Ontario. It is dedicated to promoting and increasing the knowledge, skill and proficiency of its member architects and licensed technologists, and administering the Act, to serve and protect the public interest.
