There are a few charities/causes that will take Canadian Tire money.

"In 2013-2014, you donated over $160 - this money was used to purchase many items for recess and gym use. Thank you for your support!"

Unless it's a large amount, it's not worth going through the trouble though. (Unless you live close to one)
The new reward card was launched a few weeks ago. You can download the app now and use that instead of carrying/collecting CT money. You also earn it at Sport Chek, Atmosphere and Marks, and you can still collect if paying with a credit card now.
Select items will feature 10x and 20x the rewards which will add up pretty quickly. You also automatically get 10x the money if you pay with your CT Mastercard, in addition to any bonus rewards.
Also makes returns much easier, as you no longer need a receipt to return something.
