Things to remember
A foreign national cannot become a permanent resident in Canada if he or she is inadmissible for reasons other than lack of legal immigration status in Canada.
A temporary resident permit (TRP) holder is inadmissible unless the circumstances that lead to the issuance of the TRP are resolved.
The person being sponsored must resolve the circumstances that resulted in the inadmissibility before submitting an application for permanent residence.
Refer to the guide for temporary resident permit holders:
Applying to Remain in Canada as a Temporary Resident Permit Holder (IMM 5554).
The family class is aimed at faster processing of spouse or common‑law partner applications from applicants outside Canada.
Processing times for spouses or common‑law partners in Canada are generally longer.
The person being sponsored can apply to a visa office outside Canada to take advantage of the family class processing standard. Processing times for applications processed in Canada are posted on our Web site.
Processing times may be longer if the principal applicant has dependent family members outside Canada that are included in the application for permanent residence.
The person being sponsored will not be granted permanent residence until family members have been examined and have passed medical, background and security requirements.
Dependent children include children in the custody of a former spouse or common‑law partner.
The person being sponsored should resolve any child custody disputes before submitting an application.
Leaving Canada can automatically cancel temporary resident status as a visitor, student or worker.
The person being sponsored has no guarantee that he or she will be permitted to return or reenter Canada if he or she leaves before permanent residence is approved. This is especially true if a Temporary Resident Visa is required to enter Canada.
Applications in this category cannot be transferred to immigration offices outside Canada.
The person being sponsored will have to submit a new application to the Case Processing Centre in Mississauga (CPC‑M) if he or she cannot return to Canada.
