"As of December 1, 2011, missions will no longer issue a counterfoil to applicants approved for permanent residence, if the “CNTRY OF ISS. OF TRAVEL DOC:” field on the COPR identifies a regular passport issued by the United States of America or a country identified in the Immigration and Refugee Protection Regulations 190(1)(a) or (b) or 190(2)(b), (c), (d), (e) or (f), or 190(2.1).
An officer may use discretion in determining whether it is necessary to see the original passport or whether a photocopy of all passport pages is sufficient. A photocopy of only the bio-data page is not acceptable, as notations may have been made on other pages regarding the individual's name, marital status or other pertinent information. This change in procedure does not remove the requirement that staff record the passport information of the approved applicant in the Global Case Management System (GCMS) or the Computer Assisted Immigration Processing System (CAIPS). Line 33 on the COPR will continue to reflect the date by which an approved permanent resident applicant must enter Canada." from http://www.cic.gc.ca/english/resources/manuals/bulletins/2011/ob348a.asp
