The Sponsor Undertaking Explained: The Promise You Cannot Take Back

What it is

When you sponsor a family member, you sign an undertaking. It is a legally binding promise to the government that you will financially support that person, and that they will not need social assistance.

If they do receive social assistance during the undertaking period, you must repay every dollar of it. And until you do, you cannot sponsor anyone else.

This is not a formality. It is a debt you agree to in advance, for an amount you cannot know, for a period of years.

How long it lasts

The period starts the day the person becomes a permanent resident. Outside Quebec:

For a spouse, common law partner or conjugal partner, three years.

For a dependent child under twenty two on the day they become a permanent resident, ten years, or until they turn twenty five, whichever comes first.

For a dependent child twenty two or older on that day, three years.

For a parent or grandparent, twenty years.

For any other relative, ten years.

Twenty years for a parent is not a typo. It is the longest financial commitment in the Canadian immigration system, and people sign it without reading it.

The part almost nobody understands

Once the person you sponsored becomes a permanent resident, there is no way to cancel or shorten the undertaking.

None. IRCC says so plainly.

You remain responsible even if the person becomes a Canadian citizen.

You remain responsible even if you divorce or separate. IRCC gives divorce and separation as explicit examples of things that do not release you.

You remain responsible even if you move to another province, or leave Canada entirely.

You remain responsible even if you lose your job, fall into debt, or your financial situation collapses.

And you remain responsible even if you asked to withdraw the sponsorship, if IRCC received or processed that withdrawal after they had already landed.

Read that list again before you sign. A marriage that ends in year one still leaves you financially liable in year three. That is the deal, and it is not negotiable.

The one moment you can withdraw

You can withdraw a sponsorship before the person becomes a permanent resident. After they land, you cannot.

If you are having serious doubts, that window is the only one you get, and it closes at the border.

What default means

Default begins when a government makes a payment that you promised in the undertaking to repay, or when you breach an obligation in the undertaking.

It ends when you reimburse the government in full, or reach an agreement with it, or cease to be in breach.

While you are in default, you cannot sponsor anyone else. The debt does not expire quietly. It sits there.

The sponsorship agreement is a separate thing

Alongside the undertaking, you sign a sponsorship agreement with the person you are sponsoring.

In it, you agree to provide for their basic needs: food, clothing, shelter, and other everyday living needs, plus dental care, eye care and other health needs that public health services do not cover.

They agree to make every reasonable effort to support themselves and any accompanying family members.

Dependent children under twenty two do not sign this agreement.

Note what the sponsor's side of that agreement includes: dental and vision care. Provincial health plans generally do not cover those. That is your obligation, in writing.

Quebec is different

In Quebec, the undertaking is signed with the provincial government, not with IRCC, and the durations differ.

For a spouse, de facto spouse or conjugal partner, three years.

For an accompanying dependent child under sixteen, at least ten years, or until they turn eighteen, whichever is longer.

For an accompanying dependent child sixteen or over, at least three years, or until they turn twenty five, whichever is longer.

For a parent or grandparent in Quebec, ten years rather than twenty.

The Quebec undertaking is equally irrevocable once the person has their permanent residence visa, and it equally survives separation, divorce, the sponsored person's naturalisation, and either party moving away.

What to do before you sign

Read the undertaking. The actual document, not a summary of it.

Ask yourself what happens if the relationship ends. Not because you expect it to, but because the undertaking is written for the case where it does.

If you are sponsoring a parent or grandparent, understand that you are making a twenty year financial commitment, and that twenty years is longer than most careers, most mortgages, and a great many marriages.
