Can I withdraw all the money I allocated for studying and bring them to Canada by cash? Study Permit

[vasiliy.grigoriev175@gmai]

I am temporarily residing in Turkey and have a USD bank account here, where all my money allocated for studying in Canada is (are) stored. However, I strongly distrust Turkish banking systems (they are extremely unreliable and do not like to make international transfers) and I have good reason to suspect that they won't allow me to transfer all my money to Canada once I come there. I think they will most likely block my bank account and ask me to return to Turkey. However, even if they allow me to make a transfer, they will take a predatory commission and exchange the money at a terrible rate (I checked their rates). So before I go to Canada, can I just withdraw all my money and bring it (them) as cash (yes, I know that I will have to declare this amount, since it will be more than 10 000 CAD).
Will the Canadian visa officer have questions and suspicions due to the fact that there will be no money in my bank account, and I will show him the necessary amount only as cash?
