What digital photo does the PR card application take?
One JPEG from a commercial photographer, uploaded in the Permanent Residence Portal: between 715 x 1000 and 2000 x 2800 pixels and no more than 4 MB. A professional scan of a printed studio photo also works; a phone picture of a print does not.
The studio’s name and address, the date taken and a receipt or similar confirmation go in a separate upload for the back of the photo. Once uploaded, the picture shows in black and white, which IRCC says is not a fault.
