Section 55 — Immigration and Refugee Protection Act: Arrest and detention with warrant

An officer may issue a warrant for the arrest and detention of a permanent resident or a foreign national who the officer has reasonable grounds to believe is inadmissible and is a danger to the public or is unlikely to appear for examination, for an admissibility hearing, for removal from Canada or at a proceeding that could lead to the making of a removal order by the Minister under subsection 44(2). An officer may, without a warrant, arrest and detain a foreign national, other than a protected person, who the officer has reasonable grounds to believe is inadmissible and is a danger to the public or is unlikely to appear for examination, an admissibility hearing, removal from Canada, or at a proceeding that could lead to the making of a removal order by the Minister under subsection 44(2); or if the officer is not satisfied of the identity of the foreign national in the course of any procedure under this Act. A permanent resident or a foreign national may, on entry into Canada, be detained if an officer considers it necessary to do so in order for the examination to be completed; or has reasonable grounds to suspect that the permanent resident or the foreign national is inadmissible on grounds of security, violating human or international rights, sanctions, serious criminality, criminality, transborder criminality or organized criminality. If a designation is made under subsection 20.1(1), an officer must detain, on their entry into Canada, a foreign national who, as a result of the designation, is a designated foreign national and who is 16 years of age or older on the day of the arrival that is the subject of the designation; or arrest and detain without a warrant —

If a permanent resident or a foreign national is taken into detention, an officer shall without delay give notice to the Immigration Division.
