I am another Canadian Kindle owner, I am going to guess that you live in Vancouver/Victoria because of the concern over the sleet?? I am in Calgary, so we do not have the same amount of sleet/rain that other places do. However I bring my Kindle with me everywhere, it lives in the big pocket of my purse. It only has the cover on it, and I have found that that is enough. I often bring mine in the bath, by the beach, etc so it has gotten damp before without it being a big deal. I really do not think you need much more than a cover, even with it being in the rain. As long as you put it away as soon as the rain starts, a little bit of damp will not hurt it.
