Hi! Your results need to be valid when you receive the AOR. Once you have that document it does not matter if your IELTS expire even 1 day later. Therefore, if your results will expire in October, you will need to receive the ITA and submit all the documents before that, so you get the AOR in time. Also be aware that in some cases the AOR arrives right after submitting all the documents, but it seems that for some people it takes a while.Thanks! If I get the ITA before october is it then valid or will i still have to give it again?
Here more info from the Government of Canada website:
Language test results must not be more than two years old at the time of application receipt, and will be used as conclusive evidence of an applicant’s language proficiency.
