Yep, same thing in Ontario. They will only give you a prescription for 1 year's supply of birth control after you have had a full exam and pap - so they make sure you're getting it annually.
Also, anytime you start or change birth control (first time or new brand or new type) the doctor will only give you a 3-month prescription so that you have to come back for a follow-up appointment after 2 1/2 months to see how you're doing, talk about any side-effects you're having, discuss, etc. before getting a prescription for the remaining 9 months.
