The Inland Spousal/Common-Law Partner Sponsorship program allows a Canadian citizen or permanent resident to sponsor his or her spouse/common-law partner for permanent resident status if the couple is already living together in Canada.
The Spousal Sponsorship program is a subsection of the Family Class immigration category, under which a Canadian or permanent resident may sponsor his or her spouse/common-law partner for Canadian permanent residence. Both the Canadian citizen or permanent resident (also called the 'sponsor') and the foreign national (the 'sponsored person') must be approved by Immigration, Refugees and Citizenship Canada (IRCC, formerly CIC) in order for the sponsored person to receive a visa.
There are two parts to the spousal sponsorship application:
The Canadian or permanent resident applies to sponsor his or her spouse or common-law partner; and
The spouse or common-law partner applies for permanent residence.
