I went myself to the airport and talked to an immigration agent, who kindly listened to me and issued a new Work Permit. I didn't have to leave the country or go to a border an re-enter.
If you already have the medical, you can go to any airport and talk to a CIC agent, they will remove the restriction and get you a new work permit. You don't have to leave the country and re-enter.
