Professional credential stamps signal verified expertise on technical deliverables in ways that typed text cannot match. Architects sealing drawings with their OAA stamp, professional engineers sealing reports with their PEO stamp, accountants applying CPA designation stamps, notaries applying notary seals, the credential stamp is the formal artifact that converts “qualified person” into “credentialed signatory.” This guide walks Canadian credentialed professionals through credential stamp design, regulatory requirements, and proper application. Part of our complete tender stationery cluster.
Why Credential Stamps Matter in Government Tenders
Many Canadian government tenders require deliverables to be signed and sealed by credentialed professionals:
- Engineering tenders require P.Eng-sealed drawings, calculations and reports per Professional Engineers Ontario (PEO) regulations.
- Architectural tenders require OAA-sealed drawings and contract documents per Ontario Association of Architects regulations.
- Surveying tenders require Ontario Land Surveyor-sealed plans and reports.
- Audit tenders require CPA-signed audit opinions per CPA Ontario professional standards.
- Legal tenders require Law Society of Ontario member signatures.
- Notarial services require notary public seals.
Deliverables submitted without the required credential are not just unprofessional; they are typically non-compliant with the tender specifications and disqualify the bid.
The Major Canadian Professional Credential Stamps

- Design specification: PEO-approved format with licence number, professional name and “P.Eng” designation.

- Order: CPA, CPA-CA, CPA-CMA, CPA-CGA designations as applicable.
Notary Public Seal
- Required for: Notarized signatures, sworn affidavits, certified copies of documents.

How to Order Credential Stamps
- Specify the credential type (P.Eng, OAA, OLS, Notary, CPA, etc.).
- Provide your licence number and full professional name as registered with your governing body.
- Specify ink colour (black or blue typical for credential stamps; check your governing body specification).
- Choose stamp body size. Larger stamps for prominent deliverable certification; smaller for routine documents.
- Approve PDF proof before manufacturing. Verify your name and licence number are correct.
Multiple Credential Holders, Stamp Strategy
Professionals holding multiple credentials (e.g., P.Eng + MBA, OAA + LEED) often order separate stamps for each credential or a combined stamp showing all applicable designations. The choice depends on which credentials apply to which deliverables.
Compliance With Your Governing Body
Each Canadian professional governing body has specific specifications for credential stamps:
- PEO publishes seal specifications; deviation can result in professional discipline.
- OAA publishes seal specifications; required for sealed architectural drawings.
- Notary specifications vary by jurisdiction.
When in doubt, contact your governing body before ordering. Our team can verify specifications based on documentation you provide.
Frequently Asked Questions
Can I get my P.Eng stamp from Cheque Store?
Yes, we manufacture PEO-compliant Professional Engineer stamps. Provide your P.Eng number and full professional name; we design the die per PEO specification and provide a PDF proof before production.
Do I need an embossing seal for notary work, or will an ink stamp work?
Most jurisdictions require embossing seals for notary work because the raised embossing is tamper-evident in ways an ink stamp is not. See our stamps and seals comparison guide.
What happens if I apply a credential stamp on the wrong document?
The credential stamp implies your professional verification of the document. Applying it incorrectly can trigger governing body discipline. Apply only to documents you have actually verified per your professional standards.
Where do credential stamps fit in tender stationery?
Credential stamps are the verified-expertise piece of the tender response. See our pillar guide, folder strategy, seal requirements, and bid deposit cheques.
