Family reunification is a main objective of Canadian Immigration, with the intent to reunite Canadian citizens and permanent residents with close members of the family class. A foreign national is a member of the family class if, with respect to a sponsor, the foreign national is:
This is a class for spouses or common-law partners in Canada and their dependent children if the spouse or common-law partner has legal temporary status in Canada.
A sponsor is a Canadian citizen or permanent resident at least 18 years old, who resides in Canada (with exception of Canadian citizens), and who meet certain requirements to sponsor a member of the family class.
The undertaking is a binding contract between sponsors and the Minister of Immigration, Refugees and Citizenship Canada (IRCC), where sponsors promise to provide the sponsored person with basic requirements from the day they enter Canada until the end of the specified period of the undertaking, set out by IRCC.
The financial test is needed to prove that sponsors can support sponsored persons for the period of the undertaking.
