I called ahead to see if their photo department were able to take and print photos for a Canadian Passport. No big deal if they couldn't, just wanted to make sure before I went.
They said absolutely, they do it all the time.
If they do, there are a lot of people having their applications rejected because of the photos this place takes. Just say you don't do it. Easy!
Instead, I am paying almost $300 to expedite my application because it wasn't correct. Thanks a lot Walgreens!
