Yes I suggest you/your dependants to get your upfront medicals. If you are at 69% on your Progress Bar and you have already done your Biometrics, and have submitted all documents required, then all is left is your background/security check. There is the concern of medical results expiring because they are valid for 1 year. With 69& progress bar, your PR will be ready long before your medicals are due to expire. My application is at 70% and completion is MAR 2022. IRCC sent me a medical request (MR) in June and I and my dependants had them done early JUL. Your application and mine are not far apart.
