A Manitoba notary public is appointed by the province's minister of finance. In order to become a notary public, you must be a Canadian citizen and at least 18 years old. You must also have a clear criminal history. Once you receive your notary public commission, it is valid for two years. You can renew your commission within six months of the expiration date to keep it active.

Complete the Notary Public Application. This application requires information such as your name, address, telephone number, age, citizenship and employment details. You can download and print a copy of this form from the Province of Manitoba website.

Submit the completed application to the address that is listed on the bottom of the application. The form can be submitted through the mail or in person. Be sure to include a $225 filing fee. This fee can be paid via credit card, check or money order. If paying with a check or money order, make it payable to the “Minister Of Finance.”

Wait to receive your commission in the mail. The province of Manitoba does not provide a time frame for your commission to be mailed.
