Canon’s are quite different from Nikon. Nikons just appear as hard drives on your computer, but Canon doesn’t allow it. Instead, you have to either install their shovelware to import or get a card reader for their CF cards.
If you have a Mac, then iPhoto knows how to read them too, so you can import them. They do get sucked deep into the iPhoto library directories, but you can find and copy them with Show File.

General consensus is that Canon cameras don’t mount onto the desktop, but is seen by iPhoto. If you want to mount it onto the Finder, you’ll need to use the card reader.
