Digital Seal

Landscape Architects are increasingly using new technologies in their daily work. The documents they produce remain subject to high standards of reliability. Active Landscape Architects who wish to produce legally reliable digital documents in compliance with AALA’s requirements can now accomplish this task with CertifiO for Professionals – Alberta Landscape Architects Digital Signature (referred to as the “Digital Seal”). Digital Seals are not to be confused with a digital image of a seal.

After extensive evaluation of the Digital Signature market, AALA has selected Notarius to provide an AALA Digital Seal to active members. 

Webinar - March 27, 2020


What does a Landscape Architect need to know about Digital Seals?

  • When am I required to use my digital seal?
    Anytime an image of your seal is being transmitted electronically (e-mail, uploads, USB KEy, etc.) you MUST seal with a digital seal.  Printing, physically sealing, and then scanning is not sufficient.
  • Is there an AALA Policy
    Yes - you can find the policy at  PRC-003-20220107.pdf
  • What is an electronic document?
    An electronic document is a document carried by electronic, logical and visual media.
  • What is a Digital Signature?
    It is the affixing of a digital signature certificate that cryptographically secures an electronic file, thus proving the origin, the authenticity of the signer, and confirming the integrity of the signed document.

  • What is a Digital Signature certificate? 
    It is a computer artifact issued and cryptographically protected by a Certificate Authority (Notarius) attesting to the veracity of the information declared in the certificate. This information may include:

    • Full name;
    • Email address.
    • Professional title;
    • Membership number;
    • Public key,
    • Validity period and the serial number of their certificate.

Presentation of the Partnership between the Alberta Association of Landscape Architects and Notarius

Notarius provides the framework and platform to allow its 33+ partners to issue Trusted Digital Signatures to their members, without the trouble of managing the technological infrastructure related to such complex solutions. In the same way, AALA controls the issuance of the ink stamp, this partnership allows AALA to be the exclusive issuer of Digital Seal. 

Active Members who wish to avail themselves of an AALA Digital Seal will begin the process of creating electronic originals and authenticating final documents using proven technology solutions that meet government standards and archiving best practices for electronic files. 

Features and Benefits

The Digital Seal affixed to a document by a Landscape Architect:

  • Guarantees the origin of the document. The origin of the document includes proof of the signer’s identity, his AALA professional affiliation (at the time of the signature) as well as the date and time of the document’s finalization;
  • Ensures the integrity of the document (as well as its data contents), so that the document has not been altered since its completion;
  • Establishes the authenticity of the document. The authenticity implies that everything necessary to prove its origin and integrity is embedded in the document;
  • Ensures the longevity of the document. Longevity provides the ability to open, read, authenticate and preserve the reliability of a document over time, or any period exceeding twelve years (rule of thumb).

The Digital Seal must remain under the sole control of its holder, it cannot be shared nor delegated under any circumstances.
