You are getting late dear, because u also need CAQ for Quebec, even online they will take almost a month, friends who applied in early May and got Medical are still awaiting the response. So don't waste time, after initial assessment, if you got medical at that time they will provide you opportunity to submit remaining documents. Regarding sponsorship, make sure enough money in your father's account, and if you have any documentary evidence from uncle just attach with application, if they need any calrificaiton that can be sorted out latter stage. (There is no hard n fast rules for them which we can recommend)
To All
Any friend of May Submission: who got good news ??
Good luck
