New CAD passport app.

the new CAD passport application(short forms) are
now available. No guarantor needed! Just 2
'references'. Only for previous passport holders.

So, I went to the office and the wait time was
1 hr. Got a 48 pager and the agent went thru
all the pages of my old passport(48 pages).
I had lots of old visas which fill up one
page. 48 pagers are $92.

Question:
why would she check all my old pages??
