Here's an excerpt from the Passport Canada Website: http://www.pptc.gc.ca/cdn/16-.aspx
"Children who have been issued a passport in their first year of life (between birth and 364 days) are entitled to a one-time gratis replacement passport. This is in recognition of the rapid change in the features of children of this age. However, the applicant must submit:
- a new application completed in full and signed by an eligible guarantor,
- new photographs taken within one month of the date the request for the gratis replacement is received,
- an original proof of Canadian citizenship,
- custody documents, if applicable, and
- the original passport.
The maximum validity period of the replacement passport is three years from the date of issue of the original passport."
