Often times folks will come in and ask for a Canada Passport photo or "just a regular passport photo", not knowing that not all country's photos are alike. Some, such as Canada, have different requirements for all of their photos and if any are literally even just a hair off, they can and often do reject photos because they are not perfect, causing unnecessary delays and aggravation. When we ask what specifically your photograph is for, we're just trying to make sure to get you what you need so you won't have any bad surprises down the road, eh? 😀
