Sponsoring a family member for permanent residence in Canada is not just an application — it's a legal promise. When you sign a sponsorship undertaking, you commit to supporting that person financially for a set number of years, and that promise does not end just because the relationship changes or the person becomes self-sufficient sooner. How long that promise lasts depends entirely on who you're sponsoring.

Understanding the sponsorship undertaking length you're signing up for — before you sign — is one of the most important things a sponsor can do. This article compares the three main family-sponsorship categories side by side.

What an Undertaking Actually Is

An undertaking is a written commitment, signed as part of a sponsorship application, that the sponsor will provide for the sponsored person's basic needs — generally food, clothing, shelter, and other essentials — for a fixed period after that person becomes a permanent resident. It's a legal obligation to the government, not just a promise to the family member, which matters if a province ever pays social assistance to the sponsored person and seeks to recover it from the sponsor.

Critically, the undertaking does not end just because:

It ends when its fixed term expires — full stop.

The Three Categories Compared

CategoryUndertaking length (rest of Canada)Governing authority
Spouse, common-law, or conjugal partner3 years from the day the sponsored person becomes a permanent residentImmigration and Refugee Protection Regulations (IRPR) s.132
Parent or grandparent20 years from the day the sponsored person becomes a permanent residentIRPR s.132
Dependent childA fixed term set out in the regulations, generally shorter than the parent/grandparent undertaking and tied to the child's age at landingIRPR s.132

As of mid-2026 — verify the current figures before relying on them, and note that Quebec administers its own, separate provincial undertaking terms that can differ from the rest of Canada.

The dependent-child figure is not reproduced here as a specific number because undertaking terms can be tied to the child's age at the time they become a permanent resident, and the exact length should be confirmed against the current regulation or with a licensed professional rather than assumed.

Why Parent and Grandparent Sponsorship Carries the Longest Commitment

Twenty years is a long time — long enough that many sponsors sign the undertaking in their thirties or forties and are still bound by it well into a different stage of life. A few things make this category distinct:

Why Spousal Sponsorship Is Shorter but Still Binding

At three years, spousal sponsorship carries the shortest undertaking of the three — but "shortest" does not mean "flexible." The undertaking survives separation and divorce. If the marriage or relationship ends during the three-year period, the sponsor generally remains on the hook for the balance of the term, because the promise was made to the government, not to the relationship.

This surprises a lot of people. It's worth having a clear-eyed conversation with a lawyer before signing, especially if the relationship is at all uncertain.

What Triggers Liability Under an Undertaking

A sponsor generally becomes financially liable if the sponsored person receives provincial social assistance during the undertaking period. The province can seek to recover what it paid out directly from the sponsor — not from the sponsored family member. This liability exists independently of whether the sponsor and sponsored person are still in contact, still living together, or still on good terms.

Frequently asked questions

Can a sponsorship undertaking be cancelled early?

Generally, no — once the sponsored person becomes a permanent resident, the undertaking runs its full term regardless of later changes in the relationship or circumstances. This is one of the most important things to understand before signing.

Does the undertaking length change if I sponsor more than one family member at once?

Each sponsored person under the application is covered by the undertaking's terms for that category; sponsoring multiple people (for example, a spouse and their dependent children together) does not shorten any individual person's term.

If my sponsored parent becomes a Canadian citizen, does the undertaking end?

Becoming a citizen does not, by itself, end the undertaking — the obligation is tied to the fixed term set at the time the person became a permanent resident, not to their later citizenship status. Confirm the specific rules with a licensed professional if this situation applies to you.

Is the undertaking the same across all of Canada?

No — Quebec administers its own, separate provincial undertaking regime with its own terms, which can differ from the rest of Canada described here. If either sponsor or sponsored person has ties to Quebec, that province's rules need separate confirmation.
