Canada High School Diploma Apostille: Notarize First or Risk Rejection

Notary embossing a high school diploma copy

Yes, a Canadian high school diploma can receive an apostille, because Canada joined the Hague Apostille Convention in 2024. Two things decide whether yours succeeds. The first is where the diploma was issued or notarized, since that sets which office issues the apostille. The second is whether it is properly notarized.

TL;DR:

  • Only diplomas from recognized elementary or high schools qualify, and an apostille works only in Convention member countries; other destinations may require embassy legalization.
  • Submit documents issued or notarized in Alberta, British Columbia, Ontario, Quebec, or Saskatchewan to that province; Global Affairs Canada handles other provinces, territories, and federal records.
  • A Canadian high school diploma must be notarized before filing, and the notary needs a valid appointment, handwritten ink signature, and readable stamp details.
  • Ontario’s published fee schedule lists $16 for a notarized legal document and $32 for an Ontario government official document; other provinces set their own rates.
  • Some provincial in person options offer same day or next day handling, while Ontario says certain document types may take up to 10 business days.

Which diplomas qualify since Canada joined the Hague Convention

Since January 11, 2024, Canada has been a signatory to the Hague Apostille Convention. One certificate, the apostille, now replaces the old multi-step authentication and legalization chain for Canadian public documents, including education records.

A diploma counts as a public document when a recognized elementary or high school issued it. Provincial guidance says diplomas are authenticated only when they come from recognized schools. A diploma from an unrecognized school is not eligible.

An apostille only works in countries that belong to the Convention. If your destination is not a member, check whether extra legalization steps through that country's embassy or consulate are needed. Our overview of Canada's apostille rules covers when those steps still apply.

Do not confuse this with an Educational Credential Assessment. An apostille confirms that a signature and seal are genuine. It does not compare your education to another country's standards.

Which authority issues the apostille for your diploma

The issuing office depends on where the document was issued or notarized. Alberta, British Columbia, Ontario, Quebec and Saskatchewan each have their own competent authority. Global Affairs Canada handles the remaining provinces, all territories and federal documents, as the requirements page explains.

Canadian diploma apostille authorities by jurisdiction

Sending your file to the wrong office is the quickest way to lose time. Check eligibility first through the official government portal, and read the notices and updates page for current guidance. A document must also be on paper, carry an original recognized signature, and go to the correct competent authority.

Ontario's Official Documents Services is a useful model. Its authentication page offers verification and apostille lookup tools. Our guide to finding the right apostille office for education credentials walks through the decision by province.

Notarization rules for high school diplomas

Elementary and high school diplomas issued in Canada must be notarized before you submit them. The notary needs a valid certificate of appointment and must handwrite their signature in ink.

The notary's stamp or seal must show:

  • Their full name
  • The province or territory of appointment
  • The type of notarial act
  • The expiration date of the appointment, where applicable

Notarization is the most common point of failure. Typical faults include a smudged or unreadable seal, a missing expiration date and no description of the notarial act. An embossed seal with no ink impression may be harder for officials to read.

The fix is simple. Have the notary redo the act with every detail visible. If the original diploma is hard to certify, ask your school for an official certified true copy and notarize that.

Step-by-step checklist to prepare and submit your diploma

Follow these steps in order:

  1. Confirm that your school is recognized by the provincial ministry of education and that you hold an original diploma or an eligible certified true copy.
  2. Decide whether the notary will certify the original or a school-issued certified true copy, and book a notary who meets provincial or federal requirements.
  3. Identify the competent authority, either your province or Global Affairs Canada, and confirm its forms and submission options.
  4. Package everything: the notarized diploma, identification, a prepaid return envelope, any destination-specific requirements and payment.
  5. Track your file, keep copies of everything, and use verification tools after issuance when available.

A few packaging details save trouble:

  • Use a trackable courier for the return.
  • Include a short cover note naming the destination country.
  • Keep scans of every page before you send anything.

Pro Tip: Ask the notary to show you the finished stamp before you leave, and check that the name, province and expiration date are all readable.

In-person filing, where a province offers it, can shorten turnaround compared with mail-in handling.

Where to send your diploma, timelines and fees

Send documents issued or notarized in Alberta, British Columbia, Ontario, Quebec or Saskatchewan to that province's competent authority. Everything else goes to Global Affairs Canada.

  • In-person provincial options can offer same-day or next-day handling for some requests.
  • Ontario's guidance says in-person requests may take up to 10 business days for some document types.
  • Mail-in routes may take longer than in-person filing, so check available options when time is short.

Ontario's published schedule lists $16 for a notarized legal document and $32 for an Ontario government official document, per the province's fee guidance. Other provinces set their own fees, so confirm current amounts before you file.

Why authentication requests come back and how to fix them

Most returns trace to a short list of faults, and our guide to apostille rejection reasons covers more of them:

  • Missing or unclear notary details
  • An expired notary appointment
  • A photocopy sent instead of an original or certified true copy
  • A file sent to the wrong competent authority

The remedies match the faults. Re-notarize with complete notary details. Ask the school for an official certified true copy. Verify eligibility before you mail anything. These points come straight from the requirements and the government's updates.

Pro Tip: Run your diploma through the government eligibility checker before you pay for rush shipping or an expedited service.

Our checklist of questions that prevent a returned apostille is worth a read before you file.

When paying for an expedited service makes sense

DIY works when your deadline is loose and your notary step is clear. A managed service earns its fee when time is short, the notarization is uncertain or you live far from the issuing office. Someone reviews your documents, files in person with the competent authority, bundles the government fees and returns the result by secure courier. Pay for that only if it saves you a real delay.

FAQ

What is the equivalent of a high school diploma in Canada?

Canadian high school graduation is recognized by a provincial or territorial diploma. Names differ by province, such as the Ontario Secondary School Diploma. The apostille authenticates the document itself, not its equivalence abroad.

What countries accept apostilles?

Over 120 countries are now Hague Apostille Convention members. Check that your destination is on the list. If it is not, you may need embassy legalization instead.

Can I walk in to get the apostille?

In some provinces, yes. Ontario offers in-person authentication, which can be faster than mail-in service. Check each office's hours and eligibility rules first.

Where can I get an apostille for a Canadian document?

It depends on where the document was issued or notarized. Five provinces have their own competent authorities, and Global Affairs Canada covers the rest. Our guide to apostilling a Canadian document explains each route.
