Commissioner for Oaths or Notary Public in Alberta Which One Do You Need?
If your document will stay in Alberta, a commissioner for oaths is often enough. If your document will leave Alberta, needs a certified copy, or may be used with another province, a foreign country, a bank, or an apostille process, use a notary public.
That is the simple answer, but the details matter. Choosing the wrong officer can mean a rejected document, a second appointment, and extra cost. This guide explains the practical difference between commissioner for oaths vs notary public Alberta services, with common examples like affidavits, statutory declarations, certified copies, land title forms, insurance proof of loss forms, and documents for use outside Alberta.
What a commissioner for oaths is
A commissioner for oaths is authorized to take oaths, affirmations, and solemn declarations. In plain language, they can witness someone swearing or declaring that the contents of a document are true.
This usually applies to two common document types.
Affidavits
An affidavit is a written statement of facts confirmed by oath or affirmation. It may be used in Alberta court filings, applications, or other formal processes where a person must swear that the information is true.
For example, a person may need an affidavit for:
An Alberta court matter
A name correction
A family-related filing
A lost document statement
A government form that requires sworn evidence
Statutory declarations
A statutory declaration is also a formal statement of truth, but it is usually declared rather than sworn. It is often used when a person needs to confirm facts for a form, application, claim, or administrative process.
For example, a statutory declaration may be used for:
Confirming identity details
Explaining a missing document
Declaring a common-law relationship
Supporting an Alberta government form
Confirming facts for an Alberta-based process
The key limit is location and acceptance. A commissioner for oaths in Alberta is generally used for documents meant for use inside Alberta. If the document is going to an Alberta court, an Alberta government office, an Alberta registry, an insurer in Alberta, or an Alberta land titles process, a commissioner may be the correct choice.
If you are asking, “what is a commissioner for oaths,” the simplest answer is this: they confirm your oath, affirmation, or declaration for an Alberta-use document. You can learn more about commissioner for oaths services if your document is staying in Alberta.
A commissioner does not decide whether the facts in the document are legally good or complete. Their role is to confirm identity, administer the oath or declaration, and complete the commissioning section properly.
What a notary public is
A notary public can do what a commissioner for oaths does, and more.
In Alberta, a notary can administer oaths, affirmations, and declarations. That means a notary can commission affidavits and statutory declarations. A notary can also handle broader document needs, including notarizations commonly requested outside Alberta.
A notary public is commonly used for:
Affidavits
Statutory declarations
Notarized signatures
Certified true copies
Travel consent letters
Documents for other provinces
Documents for foreign countries
Forms for foreign banks
Documents that need authentication or apostille steps
A major difference is certified copies. If you need a copy of a passport, driver’s licence, birth certificate, degree, transcript, permanent resident card, or other document certified as a true copy, a notary public is usually the right officer.
This is where people often confuse a notarized vs commissioned document. A commissioned document usually means the person swore or declared the truth of the contents before a commissioner. A notarized document may include that, but it can also include a notarial certificate, certified copy, or signature notarization for broader use.
Use notary public services when the receiving party asks for a notary, when the document will leave Alberta, or when the document must be accepted by an institution outside the province.
Where to use each
The easiest way to choose is to ask, where is the document going? The destination often decides whether a commissioner or notary is the safer choice.
If the document is for | Usually use | Common examples |
Alberta court | Commissioner or notary | Affidavits, sworn statements, court forms |
Alberta government form | Commissioner or notary | Statutory declarations, identity declarations |
Insurance proof of loss in Alberta | Commissioner or notary | Sworn proof of loss, claim declaration |
Alberta land titles | Commissioner or notary | Land title affidavits, declarations |
Another Canadian province | Notary public | Documents going to BC, Ontario, Saskatchewan, or elsewhere |
Outside Canada | Notary public | Foreign bank forms, visa documents, overseas applications |
Apostille or authentication | Notary public | Documents that need further official verification |
Certified copy | Notary public | Passport, ID, degree, transcript, birth certificate copy |
Commissioners are commonly used for Alberta courts, Alberta government forms, proof of loss documents, and land title-related paperwork. If the form is created for Alberta use and asks for a commissioner for oaths, a commissioner is usually enough.
Notaries are the safer choice for anything leaving Alberta. That includes documents for other provinces, foreign governments, foreign banks, immigration-related paperwork, international school applications, overseas property matters, and documents that may require apostille.
Canada now uses the apostille process for many public documents going to countries that are part of the Hague Apostille Convention. The exact route can vary depending on the document and where it was issued, but the practical point is simple: if apostille or authentication is mentioned, start with a notary.

Who charges less
A commissioner for oaths usually costs less than a notary public. That makes sense because the work is narrower. A commissioner is generally confirming an oath, affirmation, or declaration for use in Alberta. A notary may be dealing with broader acceptance, certified copies, documents leaving the province, or documents that need to fit foreign or interprovincial requirements.
So, if your Alberta-only form clearly asks for a commissioner, choosing a commissioner may save money.
The risk is choosing based only on price. If the receiving party rejects the stamp, the lower fee is no longer a saving. You may need a second visit, a new appointment, a corrected notarization, or a fresh copy of the document.
For example:
A statutory declaration for an Alberta registry process may only need a commissioner.
A passport copy for a foreign bank usually needs a notary.
A sworn statement for Alberta court may be commissioned.
A consent letter for international travel is usually better notarized.
People often search for commissioner for oaths cost when price is the first concern. Price matters, but acceptance matters more. The best question is not only “who is cheaper?” It is “who will the receiving party accept?”
Wider acceptance
A notary public has wider acceptance than a commissioner for oaths.
A commissioner’s authority is closely tied to Alberta use. That is why a commissioner is often fine for Alberta courts, Alberta forms, and Alberta administrative processes, but may not work once the document crosses a provincial or national border.
A notary is more commonly recognized across Canada and abroad. That wider recognition is why many institutions specifically ask for notarized documents. Banks, universities, immigration offices, foreign lawyers, pension offices, and government departments outside Alberta may not understand or accept an Alberta commissioner stamp.
This does not mean every document must be notarized. It means a notary is often the safer choice when acceptance is uncertain.
Common signs that you should use a notary include:
The document says “notary public”
The document is going to another province
The document is going outside Canada
The recipient is a foreign bank, school, lawyer, or government office
The document needs a certified true copy
The document may need apostille or authentication
The receiving party has not said that an Alberta commissioner is acceptable
If the recipient asked for a notary public Edmonton service, do not substitute a commissioner of oaths Edmonton service unless the recipient confirms it in writing.
Not sure?
If you are not sure, say where the document is going before the appointment starts.
That one sentence often solves the problem. For example:
“This is for Alberta Court of Justice.”
“This is for Land Titles in Alberta.”
“This is for an insurance proof of loss.”
“This is going to BC.”
“This is going to a bank in India.”
“This is for a school in the United States.”
“This needs apostille.”
“The recipient asked for a certified copy.”
The officer can then decide whether a commissioner is enough or a notary is the better option. If there is any doubt, ask the receiving party what they require. The receiving party has the final say because they are the one accepting or rejecting the document.
This is especially important for documents for use outside Alberta. A form may look simple, but the destination may require a notary, a specific certificate, or an apostille step.
If you are deciding notary vs commissioner which to use, do not start with the stamp. Start with the destination.
Common mistakes
Choosing a commissioner for a document leaving Alberta A commissioner stamp may be rejected by another province or foreign recipient.
Asking a commissioner to certify a copy Certified true copies are usually handled by a notary public, not a commissioner.
Assuming cheaper is always better A lower fee does not help if the receiving party refuses the document.
Signing before the appointment Many affidavits, declarations, and notarized signatures must be signed in front of the officer.
Forgetting to bring valid identification The officer must confirm identity before commissioning or notarizing the document.
FAQ
Can a commissioner certify a copy?
Usually, no. A commissioner for oaths is mainly there to administer oaths, affirmations, and declarations. If you need a certified true copy of an ID, passport, degree, transcript, or similar document, use a notary public.
Can a notary do all a commissioner does?
Yes. A notary public can administer oaths, affirmations, and statutory declarations, so a notary can do the core work of a commissioner. A notary can also provide services a commissioner usually cannot, such as certified copies and documents for broader use.
Is a commissioner stamp accepted in BC?
Do not assume it will be. A commissioner for oaths in Alberta is generally used for Alberta documents. If the document is going to BC, ask the recipient whether they will accept an Alberta commissioner stamp. In many cases, a notary public is the safer choice.
What if I picked the wrong one?
Contact the receiving party and ask what they require. If the document needs a notary instead of a commissioner, you may need to attend again and have the document notarized properly. Do not alter the stamp or certificate yourself.
