5.36. Suspension of processing
Processing of a sponsorship application may be suspended if a sponsor or co-signer
becomes subject to:
• citizenship revocation proceedings;
•
an inadmissibility report under A44(1);
• serious criminal charges (i.e. involving an offence punishable by a maximum
term of imprisonment of at least 10 years);
• suspension under A63(4) - appeal to IAD on permanent residency obligations is
outstanding.

Loss of Status and Removal
Report on Inadmissibility
Preparation of report
44 (1) An officer who is of the opinion that a permanent resident or a foreign national who is in Canada is inadmissible may prepare a report setting out the relevant facts, which report shall be transmitted to the Minister.
41 A person is inadmissible for failing to comply with this Act
- (a) in the case of a foreign national, through an act or omission which contravenes, directly or indirectly, a provision of this Act; and
- (b) in the case of a permanent resident, through failing to comply with subsection 27(2) or section 28.
28 (1) A permanent resident must comply with a residency obligation with respect to every five-year period.
So, there is a direct link from failing to comply with the Residency Obligations (A28) leading to Inadmissibility (A41(b)) to a report (A44(1)) and suspension of the application (IP-02).
