Thats completely upto you. Canada Post expresses takes 2 days. There are some couriers that deliver next day.Hi, does anybody has an idea what courier service to use? And do i have to request the signature option too with the courier service? Do i have to put the pictures in a small envelope with the application?
As for the signature, thats again a personal choice. For your peace of mind, get that option.
For the pics, yes you can send them in a small paper or transparent envelope. Anything that would save them from being damaged.
All of your question's answers are personal choices. None of them affects your actual application. Good luck
