Here is my case :- i did my 12 in 2011 . and in 2013 i applied for my student visa for sept intake in hr diploma for 3 yrs. And luckily i have got student visa from july 2013 to april 2016. i went canada on 17 august and attended my school from 3 september to 5 oct , but unfortunately for emergency family reasons i had to come back to my home country india 
. now m currently doing bachelors in business administration it will b hopefully completed by 2015 end. i am planing to again apply for my student visa for september session 2016 . i know i will have to do my ielts ,medical and living expense all again . my question is that will i again get my visa for further study easily? . as there is no rejection of visa on my passport.
visa will b extended or i will get again a new study permit and visa?
