Am i close to getting a decision

Submitted my study permit application late (july 13th) due to some delays. Gave biometrics same week. Got an email back last week thursday saaying the need more proof of being able to pay for tuition and proof that i have the funds to sustain myself. Both of which i can get without much difficulty but i would like you guys help as to what to send them.

The deadline to submit is the 7th and i plan to submit on the 5th and a meeting with immigrartion at my school. I dont think i need the medical becuase i think they wouldve asked for it along side the information. Maybe having an eTA prior to applying helps as well. My flight is on the 22nd. Will i get a decision before then? Based on the processing times for the different countries mine is 4 weeks.
