I find it unbelievable that a doctor can be an acceptable passport
guarantor on one kind of passport form and not another.

Why is my doctor, Gerald Goldman, not acceptable as a guarantor on a passport application? He's been a doctor in Canada for close to 40 years. He's known my wife and I for over 15 years. He has been a guarantor for hundreds of passport applications in the past.
 
Nothing has changed about his blue chip credentials.
 
Unfortunately his status changed as a guarantor because he doesn't have a passport himself. However, he could be "acceptable" again, if I could find an "old passport form" for him
to fill out. (That advice came from Ruby Dhalla's office.)
 
Obviously, what's important here is forms and/or fields on forms rather than the validity of what's in them.
 
Passports should contain truthful content guaranteed by certified Canadian professionals.
 
My doctor's validity as a guarantor didn't change because he doesn't have a passport.
