When you need to have a document officially witnessed or sworn, you might hear about two types of officials: a Notary Public and a Commissioner for Oaths. Both play important roles in verifying documents and administering oaths, but they are not the same. Understanding the differences between these two can save you time, money, and confusion, especially if you live in Saskatchewan or are dealing with legal matters there.
This guide explains the key differences between a Notary Public and a Commissioner for Oaths in Saskatchewan, what each can do, and when you should use one or the other.

What Is a Notary Public?
A Notary Public is an official appointed by the provincial government to perform a wide range of legal formalities. Their main role is to authenticate and certify documents for use both within Canada and internationally.

Witnessing signatures on legal documents such as contracts, affidavits, and powers of attorney

Notaries have broader authority than Commissioners for Oaths, especially for documents that cross borders.
What Is a Commissioner for Oaths?
A Commissioner for Oaths is a person authorized to administer oaths and take affidavits or declarations within Saskatchewan. Their role is more limited compared to a Notary Public.
Key Responsibilities of a Commissioner for Oaths
Administering oaths and affirmations for affidavits and statutory declarations

Taking sworn statements for use in court or government processes within Saskatchewan
When to Use a Commissioner for Oaths

Practical Examples to Understand the Roles
Example 1: Buying Property in Saskatchewan
If you are buying property in Saskatchewan and need to sign a power of attorney or affidavit, a Commissioner for Oaths can witness your signature and administer the oath. This is sufficient for provincial legal purposes.
Example 2: Sending Documents Abroad
If you need to send a certified copy of your diploma to a university outside Canada, you will need a Notary Public to certify the copy. The notary’s seal ensures the document is accepted internationally.
Example 3: Preparing a Will
For a will that will be used only in Saskatchewan, a Commissioner for Oaths can witness the signing. But if the will involves assets or legal matters in other countries, a Notary Public may be required to notarize the document.
How to Find a Notary Public or Commissioner for Oaths in Saskatchewan
Notary Publics are often lawyers or specialized professionals. You can find them through law firms or notary offices.
Commissioners for Oaths include lawyers, paralegals, and other authorized individuals. Many government offices and legal service providers offer this service.
Before visiting, confirm the services they provide and any fees involved.
Costs and Time Considerations
Notary Public fees tend to be higher due to the broader scope and international recognition of their services.
Commissioner for Oaths fees are usually lower and suitable for simpler, local legal needs.
Both services often require an appointment, but some Commissioners for Oaths may offer walk-in services.
Summary
helps you choose the right official for your document needs in Saskatchewan. Use a Commissioner for Oaths for local affidavits and sworn statements. Choose a Notary Public when you need certified copies, notarization for international use, or broader legal services.
If you are unsure which service you need, ask the organization requesting the documents or consult a legal professional. Taking the right step ensures your documents are valid and accepted without delays.
If you have documents that require official witnessing or certification, start by identifying whether your needs are local or international. Then, contact the appropriate official to get your documents properly handled. This simple step can prevent costly mistakes and keep your legal matters on track.
