The following has been updated and is available on the CBSA website:
Memorandum D2-5-11 - Administrative and Operational Guidelines for Commercial Air-mode Carriers for the Processing of Prescribed Traveller Information Pursuant to the Requirements of the Canada Border Services Agency
http://www.cbsa-asfc.gc.ca/publications/dm-md/d2/d2-5-11-eng.html

This memorandum outlines the Canada Border Services Agency’s (CBSA) requirements and administrative policies regarding the provision of prescribed advance passenger information and reservation information with respect to persons being transported to Canada by commercial air carriers.

This memorandum has been revised to clearly explain who is accountable for the provision of passenger information; define “commercial carrier”; outline message format and system outage requirements; offer a model privacy notice for travellers, and provide revised penalty information and contact information.
