Passport Photos for PR Sponsorship

[JMilne]

I've recently had Canadian standard passport photos done for my application. The specifications state the rear of one photo must have the name & DOB of person (me) along with date, name & address of photography studio. My photographer has stuck a pre made label on the rear, my form states to not use stickers, the photographer was adamant it wouldn't be an issue. Anybody know how strict they are about this? Personal experience perhaps. The photographer does many Canadian photos here in Melbourne.

Just his details are on the sticker, my name and DOB is in pen.
