There are many places to rent cars, places that are also in The States. By the average meal, it depends where you go, the restauraunt, what province(s), etc. Gas prices are now sticking from 81.2-94.6 around my place. For tours, it depends which company you go to, and what you want to see.

I know of a couple websites, do you know where she is going to be headed in Canada? Or what she would like to see?
