The “Lonely Canadian” rule isn’t a separate immigration program—it’s an informal name people use for IRCC’s “Other relative” option under family class sponsorship. In rare cases, a Canadian citizen or permanent resident may be able to sponsor one relative of any age (such as an aunt, uncle, or cousin) for permanent residence.
To qualify, the sponsor must meet all of these core conditions:
You’re related to the person by blood or adoption.
You don’t have a living relative you could sponsor instead, such as a spouse/common-law/conjugal partner, child, parent, grandparent, or an eligible orphaned sibling/niece/nephew/grandchild.
You also don’t have any relatives in Canada (including an aunt/uncle or any of the close relatives listed above) who are a Canadian citizen, permanent resident, or registered under the Indian Act.
One helpful nuance: if the relative you sponsor has a spouse/partner or dependent children who will immigrate with them, they must be included in the same sponsorship application.
