Canadian Certificate of Identity

The Canadian Certificate of Identity is an international travel document issued by Immigration, Refugees and Citizenship Canada (formerly by Passport Canada) to a permanent resident of Canada who is not yet a Canadian citizen, is stateless, or is otherwise unable to obtain a national passport or travel document. It is a biometric document with a grey (formerly brown) cover and is bilingual in both English and French. The validity period of the travel document is determined by the issuing office.
Use.
The Certificate of Identity may be used for travel to all countries/territories specified in the travel document, apart from the bearer's country of citizenship if he/she is not stateless.
The holder of a Canadian Certificate of Identity issued by virtue of his/her statelessness and legally resident in Canada can enter Slovenia visa-free for a maximum of 90 days within a 180-day period. This visa exemption does not apply to those who hold a Certificate of Identity because they have been unable to obtain a national passport, rather than being stateless.
In theory, there is a visa exemption for Germany if the Certificate of Identity has been issued in accordance with the rules in the Convention Relating to the Status of Stateless Persons. However, because Canada is not a signatory to the Convention, in practice there is no such visa exemption.
