Notarius or ConsignO certificate won't load? Entrust certificate error? DocuSign says your signature is invalid? We diagnose and resolve Canadian digital signature, certificate and PKI errors live over a screen-shared remote call — usually in a single session.

Government, legal and enterprise signing platforms used across Canada.
Share a screenshot of the error, your OS version (Windows 11, macOS Sonoma) and the app (DocuSign, Adobe Acrobat, ConsignO) so we pinpoint the cause fast.
We join a secure remote session, reproduce the failure and trace it to the real root cause — driver, certificate, middleware or trust chain.
We apply the fix and watch you sign successfully in the same session. You leave with a working signature and a written summary if needed.

Canada's professional signing market is unusual: engineers, architects, notaries and accountants overwhelmingly use CertifiO certificates from Notarius, validated through ConsignO Desktop or ConsignO Cloud, while corporate and federal work leans on Entrust — a Canadian-headquartered CA whose roots sit in both the AATL and the Government of Canada's internal PKI. Provincial professional orders such as the Ordre des ingénieurs du Québec and Engineers and Geoscientists BC accept a sealed PDF only when the CertifiO certificate validates with the professional attributes intact, which is why a document that opens fine on your machine gets bounced by the reviewing authority.
Federal workflows add GCKey and the Government of Canada internal CA, and CRA My Account uses its own authentication path that is frequently confused with certificate signing. Bilingual environments cause a subtle failure of their own: French-language Windows builds install ConsignO and SafeNet components under localised paths, and mixed-language installs leave the middleware pointing at a directory that no longer exists.
PIPEDA and the Secure Electronic Signature Regulations define a 'secure electronic signature' federally, and only a certificate-based digital signature from a recognised CA satisfies it — which is why federal departments and regulated professions reject typed or drawn signatures outright. Quebec applies its own framework through the Act to establish a legal framework for information technology, and the provincial law societies and engineering orders publish sealing requirements on top of that. Ontario's Electronic Commerce Act and equivalent provincial statutes cover ordinary commercial agreements, where a DocuSign envelope is normally sufficient.
The practical consequence: the same PDF can be legally valid for a commercial lease and simultaneously unacceptable for a municipal permit submission.

Straight answers for Canadian Notarius, ConsignO, Entrust and DocuSign issues.
Nine times out of ten the CertifiO certificate is present but ConsignO cannot reach it — either the Notarius Signature Service is not running, the annual identity re-validation lapsed and the credential expired, or a Windows update reset the middleware path (common on French-language installs). We reproduce it live, confirm which of the three it is, and restore signing in the same session.
Orders such as the OIQ and Engineers and Geoscientists BC require the professional attributes inside the CertifiO certificate to survive validation. If the PDF was flattened, printed to PDF, or re-saved after sealing, the byte range breaks and the seal no longer verifies. We check the signature integrity, identify which step destroyed it, and set up a workflow that keeps the seal intact.
No. Under PIPEDA and the Secure Electronic Signature Regulations, a federal secure electronic signature must be certificate-based from a recognised CA — which is why departments and regulated professions reject typed or image signatures. A DocuSign envelope is normally fine for ordinary commercial agreements under provincial e-commerce statutes; it is not enough for a municipal permit or a federal filing.
Yes. "The signature is valid, but the signer's identity could not be verified" on an Entrust chain almost always means the intermediate CA is missing from the machine or the CRL/OCSP endpoint is blocked by a corporate proxy. We install the correct intermediate, verify revocation checking works, and confirm Acrobat shows a green validation before we finish.
Yes, and we start by separating the two: a CRA or GCKey sign-in loop is an authentication problem, not a certificate one, and reinstalling token drivers will never fix it. We diagnose which layer is failing and resolve certificate trust, middleware and Windows/macOS signing for federal workflows — working alongside your departmental IT where the device is managed.
No fix, no fee. If we can't identify the root cause during the session you don't pay. When the fix requires a CA-side action — a reissued certificate from Notarius or Entrust — you still receive a written remediation report with the exact steps and who to contact.
