Forgot picking up study permit

[Lan Pham]

Hi everyone. I unfortunately forgot to pick up my study permit at the airport on my arrival to Canada. I talked to IRCC and was asked to leave Canada and then return which help me get my new study permit. I just wonder whether I have to apply for the new study permit through the visa office in my country and get the Letter Of Introduction which will be shown to the Canada Border Service on my way to Canada. One more thing, the Letter of Introduction for my old study permit which i forgot taking at the airport was lost.
