It is completely up to each individual office as to what their policy is. I'd contact the very location where you will be renting. In fact, I'd be contacting several offices. I am so used to getting incorrect information, that I contact them several times with the exact same question, to see if I get the same answer. Often I do not.

When you get closer to the border, they all allow travel into Canada, but when you rent as far away as SF, it is questionable.
