kollins said:It simply means the potential Canadian stamp to be affix on your passport document will be valid till September,2015 been the date your passport document will expire.If you plan to land earlier than that,you have no worries as you won't be affected.......you can renew your passport document on arrival to Canada.
I believe the one month is not enough reason to renew it.Besides,I'm not too sure the Nigerian immigration will grant you renewal right unless your passport expiry date is about 6 months time.....for you,it should be around February or March,2015.
Cheers.
K baba thanks so much, God bless You
