If you wish to contribute anything to these Canadian soldiers, there is an organization called "Canadian Angels" . Wendy Sullivan, who hosts this effort, allows you to 'adopt' a soldier, 'register' a soldier, and donate via paypal. She says,

"I started Canadian Angels because I felt there was a need for our Armed Forces to know that the people back home in Canada supported them. For years programs like this have existed in the United States, but for our brave Canadian men and women fighting in Afghanistan and stationed around the world, there has been very little."
