1. The guarantor can be different for each application if that is what you want. Each application is handled independently. It probably makes sense to have one guarantor for all applications.When applying for canadian passport as a family (2 adults, 1 minor):
1. Must we all have the same Guarantor and references?
2. Does the Guarantor have to attest on the same passport photo that was signed by the photographer, or can he attest on the 2nd passport photo?
2. The application form is not explicit on this, but the photographer will most likely stamp one photo with the words required. See Pro Passport Photo's website for an example.
