Getting invited into the Parent and Grandparent Program is only the beginning. Once a sponsor is actually building the application, a different set of problems tends to show up — income calculations that don't hold up, documentation that doesn't quite match, and a long-term legal commitment that's easy to underestimate.

Here are the most common parent grandparent sponsorship mistakes we see, organized by where in the process they tend to appear.

Before You're Even Invited: Getting the Basics Wrong

Errors in the Minimum Necessary Income Calculation

The Minimum Necessary Income (MNI) test is assessed against your recent Notices of Assessment and generally involves reviewing more than one recent tax year, and accounting for your full household size, including the family members you're sponsoring. Two mistakes are especially common: miscounting which tax years apply, and forgetting to include existing household members when calculating the required threshold. Because the dollar thresholds themselves change periodically and vary by family size, don't rely on a number you saw somewhere online — confirm the current threshold before you calculate anything.

Underestimating the Length of the Undertaking

Parent and grandparent sponsorship carries a much longer financial undertaking than spousal sponsorship — currently twenty years from the day the sponsored person becomes a permanent resident, under current regulations (verify this figure before relying on it, as undertaking lengths can be subject to change). Sponsors sometimes treat this as a formality rather than the binding, long-term financial obligation it is, which can create real strain if circumstances change later. Once your parent or grandparent becomes a permanent resident, this undertaking generally cannot be cancelled, even if your relationship or financial situation changes.

Documentation Gaps That Trigger Delays

Co-Signer and Household Composition Mistakes

If a co-signer is involved, both the sponsor's and co-signer's information needs to be accurate and consistent, and both take on obligations under the undertaking. Misunderstanding who is financially responsible, or assuming a co-signer's involvement is temporary, is a frequent source of later disputes.

Treating the Application as Finished Once It's Submitted

A PGP application isn't a one-and-done submission. Processing can stretch on for a considerable period, during which IRCC may request updated documents, ask clarifying questions, or need to be notified of a change in circumstances, such as a change of address or a shift in your household composition. Sponsors who stop paying attention to their file after submitting it risk missing a request that has a firm deadline attached, which can jeopardize an otherwise strong application.

A Pre-Submission Checklist

Frequently asked questions

Does a mistake in my MNI calculation mean automatic refusal?

Not necessarily, but if your calculation is wrong and your actual income doesn't clear the required threshold once IRCC reviews your Notices of Assessment, your application can be refused on that basis. It's worth double-checking your math against current figures before you submit, not after.

Can I add a co-signer if I don't meet the income threshold on my own?

In some circumstances a co-signer can help meet the income requirement, but the co-signer takes on real financial obligations under the undertaking too. This is worth discussing with a lawyer before you commit someone else to that responsibility.

What if my parent or grandparent's police certificate expires before IRCC finishes processing?

Processing delays outside your control sometimes require updated documents partway through. Staying on top of any correspondence from IRCC and responding promptly to requests helps avoid a document expiring unnoticed.

Is the twenty-year undertaking really binding even if I can no longer afford it?

Yes — the undertaking is a legal commitment that generally continues regardless of a later change in your financial circumstances or your relationship with the sponsored person. That's exactly why the income and long-term planning side of a PGP application deserves careful thought before you apply.

Do I need to tell IRCC if my address or household changes while the application is pending?

Yes, generally. Keeping your contact and household information current with IRCC while a sponsorship is pending helps avoid missed communications and gives an accurate picture of your ongoing eligibility.
