While Apple(US) has a full recycling program in place (if you purchase a new Apple product the US branch of Apple Inc. will recycle *any* computer and monitor you choose to bring in) Apple(Canada) is not quite there yet.

However, the web page at:
http://www.apple.com/ca/environment/recycling/ipodrecycling/

...describes the current Apple(Canada) recycling plan:

Apple’s recycling program offers free and environmentally friendly disposal of your iPod and cell phone with no purchase necessary.



Free iPod and cell phone recycling

Apple’s commitment to responsible environmental citizenship includes ensuring that an iPod is properly disposed of at the end of its useful life. The recycling program covers your iPod or any cell phone — regardless of the manufacturer or model. Apple’s recycling program makes it easy for you to help protect the environment.

When the time comes for you to recycle, Apple makes it quick and free.

Visit the iPod and cell phone recycle page and select the quantity that you want to recycle.
