Canadian citizen applying for Canadian Passport

"Guarantor?"...  According to a dictionary "a person who makes or gives a guarantee"...

I who hold Japanese passport with Canadian Permanent residence was supposed to shut up my mouth for a while:)  And yet I had a chance to read "Canadian Citizen's newly application for Canadian passport" on Canada government website.

First thing in the morning ... what Guarantor means...?  This is my simple wondering after I read the following sections:

(Duties of a guarantor)

Your guarantor must perform the following tasks free of charge:

1.Complete and sign the "Declaration of Guarantor" section of your application form.

2.Write, "I certify this to be a true likeness of (name of applicant or child)" on the back of one of the passport photos and sign.

3.If applicable, sign and date a copy of each document to support your identity.

The applicant must not assist the guarantor in performing his or her duties. If your guarantor requires assistance, contact Passport Canada.

• My wondering is... to all of the above.
• ...what if any folk of guarantor is in a long distance since an applicant moved to a new place for any reason? Inconvenient...

Eligible guarantors

(Your guarantor must)
1.Hold a 5-year or 10-year Canadian passport that is valid Footnote 2 or has been expired for no more than one year, on the day you submit your application;

2.Have known you (the applicant) personally for at least two (2) years.

In the case of a child, the guarantor must have known you (the parent or legal guardian who is applying on behalf of the child) personally for at least two (2) years and must have knowledge of the child;

3.Be a Canadian citizen 18 years of age or older;

4.Have been 16 years of age or older when he or she applied for his or her own passport;

5.Provide the requested information contained in his or her passport;

6.Be accessible to Passport Canada for verification;

7.Live in Canada, in the United States or in any of the other areas where submission of the "in Canada and in the USA" application form is authorized (Bermuda, American Samoa, the Midway Islands, Puerto Rico and the US Virgin Islands). It is not necessary that the guarantor reside in the same country as the applicant.

• My wondering is...to 1.2. & 3.
• ...What if an applicant has any folk who is not even Canadian citizen but personally have been knowing well at least two (2) years?...

(Now in the case of regular renewal application)

You may use this form to renew a regular passport only if all these conditions are met:
1.you were at least 16 years of age at the time of your previous application;

2.the name on this application form is exactly as it appears on page 2 of the submitted passport ;

3.you submit a previous Canadian passport that:is valid or expired for no more than one year ;

4.was/is valid for five (5) years ;

5.is not damaged; and was never reported lost or stolen.

• My wondering is... to 5.
• ...How can an applicant tell if it is damaged or seems to be? By checking the front page with bar code? or by actually officer's scanning to see if its necessary information & data available on a specific system? or otherwise officer's casual eye check?...

 With Regard,
 I'll shut up my mouth here:)
