CHANGE IN CIRCUMSTANCES:
You must immediately advise our office by email should there be a change in your personal circumstances, or the personal circumstances of any of your family members, whether they are accompanying you to Canada or not. This might include any of these situations:
· Change in civil status by reason of marriage, cohabitation, divorce, separation, annulment or death;
· Death of applicant, family member or sponsor;
· Birth or adoption of a child;
· Change in health, including pregnancy;
· The laying of any criminal charges or criminal convictions;
· Change in your mailing address, email address, contact number;
· Change or cancellation of immigration representative;
· Withdrawal of your application
UNDECLARED AND UNEXAMINED FAMILY MEMBERS:
Paragraph 117(9)(d) of the Immigration and Refugee Protection Regulations excludes from future sponsorship any foreign national who is not declared and examined at the time the prospective sponsor applies for and obtains permanent residence. If you or any of your family members fail to declare and present for examination any family member as defined by the Regulations, then you or your family member will not be able to sponsor the undeclared family member at a later date as a member of the family class.
Subsection 1(3) of the Regulations defines “family member” in respect of a person as
(a) the spouse or common-law partner of the person;
(b) a dependent child of the person or of the person’s spouse or common-law partner; and
(c) a dependent child of a dependent child referred to in paragraph (b).
All family members, whether or not they are accompanying you to Canada, MUST be declared and presented for examination to assess whether they are admissible to Canada. A false declaration on your IMM5406 (Additional Family Information form), any failure to declare a family member, or failure to present a family member for examination constitutes misrepresentation and may render you inadmissible to Canada for five (5) years.
