Thanks so very much! You're very kind.

I'm arriving in YSB (Sudbury, ON) at 2:00 PM on 12/2/10 and then returning the car at YYZ (Toronto) at 3:00 PM (or earlier if the one hour over costs me) on 12/12.

Btw, I'm staying in Sudbury for four days, driving to Kitchener where I'll be staying for six, and then returning at YYZ. I've heard that maybe deals can be struck if you drop off and pick up half way through, though I wonder if two one way trips (Sudbury to Kitchener, Kitchener to Toronto) would be cheaper.
