Do you actually need a guarantor?
Not everyone does — and this is the single most useful thing to check before you go looking for one.
- Renewing an adult passport? You do not need a guarantor, and no one needs to sign your photo. You still need a compliant photo, but the guarantor step doesn’t apply to you.
- First-time (new) adult passport? Yes — you need a guarantor, and they must sign the back of one of your photos.
- Not eligible to renew (for example, an expired-too-long or lost passport)? Your application counts as new, so a guarantor is required.
- Applying for your child? A guarantor is needed, and the parent or guardian submitting the application cannot be the guarantor. The other parent can, if they qualify.
Who can be your guarantor
For a regular (blue) passport applied for within Canada, your guarantor can be anyone who:
- Is a Canadian citizen aged 18 or over
- Holds a valid Canadian passport
- Has known you for at least two years
- Is available to be contacted by IRCC if needed
The rule most websites get wrong
You may still see sites claiming your guarantor must be a doctor, lawyer or other professional, and cannot be a family member. That is the old rule. Today there is no profession requirement, and a family member or someone in your household can be your guarantor.
Applying from outside Canada? If a Canadian citizen guarantor is hard to find, IRCC allows an occupation-based guarantor who doesn’t have to be a Canadian citizen. Your guarantor can’t charge you, and you can’t help them fill in their part.
What your guarantor signs on the photo
This is the part unique to Canada — and where it goes wrong. On the back of one of your two identical photos, your guarantor writes:
“I certify this to be a true likeness of [your full name]”
…then signs it, dates it, and adds their phone number. The second photo is left blank.
Separately, the back of that same photo must show the photographer or studio name, address, and the date the photo was taken — and that date must be within the last six months.
Top guarantor mistakes that get applications returned
- Signing the back of both photos instead of just one
- Signing the front (image side) instead of the back
- A guarantor who hasn’t known you two years or can’t be reached
- Missing the photographer name, address, or date
- A photo older than six months
The signature takes a minute. The photo is the trap.
Finding a guarantor and getting a signature is a small, human task. The part that actually gets Canadian applications rejected is the photo itself: it has to be an exact 50×70mm, with your face measuring 31–36mm from chin to crown, a plain white or light background, no glasses, a neutral expression, and the right resolution to print sharply. Miss any one of those and IRCC rejects the whole thing — guarantor signature and all — and you start over.
Doing it yourself means measuring the crop to the millimetre, controlling the lighting and background, and printing at true size. It’s fiddly and easy to get wrong.
The lazy way: upload a selfie and we return a print-ready, IRCC-compliant 50×70mm photo in about 60 seconds. You print two copies, add the photographer details and your guarantor’s signature to the back of one, and submit. If IRCC rejects the photo, your money back.
Get the compliant photo, then get it signed
We handle the 50×70mm sizing, background and IRCC compliance. You handle the signature.
