What Is a Certified True Copy?
A certified true copy is a photocopy of an original document that has been compared to the original and confirmed to be a true and complete reproduction. The person certifying the copy adds a statement, signature, and official stamp or seal confirming that the copy matches the original document.
Certified true copies are commonly required when:
the original document must be kept by the owner, or
the receiving organization does not want to risk losing the original.
In Ontario, certified true copies are typically prepared by a notary public or a lawyer, both of whom are authorized to certify copies of documents.
Why Certified True Copies Are Important
Certified true copies serve several important purposes:
Protection of originals: You can keep valuable documents such as passports or diplomas safely in your possession.
Acceptance by institutions: Many government bodies, schools, financial institutions, and foreign authorities require certified copies rather than regular photocopies.
Proof of authenticity: Certification provides assurance that the document has not been altered or falsified.
For example, if you are applying for work or school outside Canada, the organization may require certified copies of your academic credentials instead of the original certificates.
What Is the Role of a Notary Public in Certifying Documents?
In Ontario, a notary public is authorized to certify that a copy of a document is a true copy of the original. When certifying a document, the notary will:
examine the original document,
compare it with the photocopy,
confirm that the copy is complete and accurate, and
apply their signature and official notarial seal to the copy along with a certification statement.
Keep in mind, the notary does not verify whether the contents of the document are true, only that the copy is a true reproduction of the original shown.

Documents That Usually Cannot Be Certified

A notary in Ontario will generally not certify:
documents that are not original, such as photocopies of photocopies,
documents that already state they must be obtained directly from the issuing authority,
documents that are altered, damaged, or incomplete, or
documents where certification must be done by a specific government body (for example, some vital statistics or medical records).
If you are unsure whether your document can be certified, it is best to confirm in advance.
Always check with the notary or relevant authority before requesting certification.
