Dont worry, the MP response is generic. The VO must have communicated that to them and they just verbatim communicated onwards to you. You will NOT have to wait till end of August. In fact, you will hear something in next 1-2 weeks. Actually, if I were you, i will start packing and preparing for your journey as atleast now you know your case is being approved, re-meds are with them, and they just have to issue you DM. Just forget about this for 1 week, prepare for your journey, and relax. All this will seem like a blur once you are in Canada with your spouse. Good luck
