Each cause below is distinct, and each links to the detailed rule so you can confirm the exact tolerance before you submit. The full cross-country breakdown is in passport photo rejection reasons.
Wrong size or aspect ratio
Submitting a square or 4:3 photo instead of the 35×45 mm portrait frame (roughly 7:9) is a structural error that cannot be corrected at the visa office. See the crop guide.
Head outside 31–36 mm
Head height too small or too large is the most common measurement failure, and it applies even when the overall frame size is exactly right. See head size rules.
Measured to the hairline
Photos cropped to a European hairline-based standard measure short against IRCC's chin-to-crown rule. Re-crop rather than reuse a Schengen photo.
Below the digital pixel floor
Files under 420 × 540 pixels are refused on upload. A 413 × 531 export at exactly 300 DPI falls just short — use 600 DPI instead.
File size under 60 KB
Over-compressing to save space pushes the file below the IRCC minimum and introduces blocking around the eyes. See resolution rules.
Non-white or busy background
Backgrounds with patterns, gradients, or colours other than white or light grey fail validation. See background colour rules.
Shadows or uneven exposure
Shadows on the face or wall, harsh side-lighting, red-eye, and blown-out highlights from direct flash all obscure facial features. See shadow rules.
Wearing glasses
Since 2016, glasses are not allowed in any Canada visa photo — even clear lenses with no glare. See glasses rules.
Smiling or open mouth
Expressions must be neutral with the mouth closed. Smiling, frowning, raised eyebrows, or squinting cause rejection at verification. See smile rules.
Hair covering the face
Hair must not cover the forehead, eyebrows, or fall across the face. IRCC needs an unobstructed view from crown to chin. See hair rules.
Filters or heavy editing
Filters, skin-smoothing, teeth-whitening, slimming or any digital alteration of your face constitutes manipulation and is grounds for rejection.
Only one print supplied
Paper and VAC submissions need two identical photos from the same session. Sending one, or two from different sessions, delays the application.
Missing back annotation
Printed photos without the studio name, address and date — or at minimum the date taken — on the back are returned for correction.
Scanned or re-photographed print
IRCC requires an original digital file. A scan of a printed photo, a photocopy, or a photo cut from a larger picture is not accepted.
Old photo
Photos older than 6 months, or that no longer represent your current appearance, are refused regardless of technical quality.
