I spend a lot of time in Canada and have the same plan as Dennis.  If
you were an AT&T Wireless customer before they merged with Cingular,
you may be able to get the $9.95/month "North America plan" and
Canada is treated as domestic calls, even when in Canada.  If you
were never an ATT wireless customer (i.e. always Cingular), they
won't give you the deal.  :(
