回复：提上来再问， 加拿大护照还有6个月有效

my canadian passport renewal completed in one month (actually 3 weeks). Key points:

1. fill and sign the form: http://www.ppt.gc.ca/form/pdfs/pptc054.pdf

2. find a professional photographer to take passport photos with his/her signature on the back of the picture.

good luck.
